Long Type Questions With Answers

Question 1.
What are the main features of the Industrial Revolution?
Answer:
The Industrial Revolution had the following main features. Firstly, industrialization made more inventions and discoveries possible. The Spinning Jenny, Mule. Cotton Gin, Steam-engine, Flying shuttle, Water frame, and lamp Power Loom were the most significant ones in this regard. Secondly, the ideology of capitalism came to replace the age-old and outdated stem of feudalism. New capitalist class industrialists and entrepreneurs came to replace the old feudal lords in European societies.

Thirdly, with the growth of industrialization, a large number of rural people migrated to industrial centers in search of better means livelihood. They joined the industries as workers and laborers. They had to, now, set up their new homes in industrial centers, away from their ancestral villages. governments were now bound to pass social legislation in favor of their living and working conditions.

Fourthly, it gave rise to specific difficulties and problems in the industrial centuries. The problem of housing workers, their health sanitation needs, working conditions, and an ever-increasing population of workers were problems to be attended revolutions to these have to be gradual, not Overnight.

Fifthly, it led to an increase in the production and sale of goods, as stated earlier, result, trade, and commerce made rapid progress. Sixthly, agriculture and industries became the two legs or the main pillars of the economy. Gone were the days when European states depended only on agriculture for their survival and sustaining themselves. Finally, industrialization led to competition among the nation-states of Europe.

From industrialism to colonialism, from colonialism to commercialism, from commercialism to imperialism, from imperialism to militarism, and from militarism to war were the natural and inevitable phases. Industrialization lay at the root of competitive nationalism. This finally led to a clash of interests and war among nations.

Question 2.
Discuss the inventions that brought in the industrial revolution?
Answer:
Spinning Jenny – The following is ‘a list of the first inventions that accounted for the outbreak of the Industrial Revolution. Textile Industry – The Englishmen had colonized India. India was famous for the quality and quantity of its production of cotton. The Englishmen took away Indian cotton to England in huge quantities. But weaving cotton and spinning its thread was done manually.

The weaver wove cloths out of threads spun out of cotton by the English housewives. It took the ladies a lot of time to spin a thread for a single piece of cloth, The need quicker spinning was urgently felt The solution to this problem came in 1764 when the Englishman James Hargreaves invented the “Spinning Jenny”. This machine could spin 8 threads at a time.

This machine revolutionized the spinning of threads. It was later improved to bring out nearly a hundred threads at the same time. This small wonder was so important that England came to have more than eighty thousand spinning jennies by 1778, the year death Hargreaves. Spinning work was thus greatly speeded up. Arkwright – John Kay invented the Flying Shuttle by which the weaving process was speeded up.

Richard Arkwright improved upon Hargreaves and Kay by inventing the water- frame in 1769 This water frame could have thinner stronger threads. In 1776 Samuel Crompton invented the spinning “Mule”, further improving upon the quality of threads. Cartwright’s Powerlopms Correspondingly, weaving also underwent great change. Hand-weaving had been improved upon by the flying shuttle of John Kay.

But this was not enough to cope with the volume of spun threads. The hand-loom was replaced by the power loom which was invented by Edmund Cartwright in 1785. The power loom did the work of many weavers and took up a fraction of their time. Powerlooms came up in every nook and comer of England.

Eli Whitney, the American inventor, invented Cotton Jin in 1793. The above inventions radically changed the textile industry for the better. It involved less manpower and still less cost reproduction while greatly increasing the volume of production (or ‘output). Profit and prosperity came as a natural result.

Question 3.
How are Coal and Iron Industries part of the Industrial Revolution?
Answer:
Coal and iron were the two basic factors of progress. Coal was the source of energy. But mining coal was difficult. The water underground made coal mining difficult. This water had to be emptied by buckets. It took a lot of time and money because holies in hundreds were used in every colliery for emptying the water bucket by bucket. Finally, Thomas Newcomen invented the 1705, Steam Engine to pump out water from the mines.

James Watt improved upon this invention in 1769 and these improved versions of the Steam Engine served the purpose in a more efficient and economical manner. Factories could now be set up in the heart of a city. Steam power helped the machines also to run better and produce more goods in less time. In the early days smelting of iron was done in charcoal furnaces. The iron, thus produced, was of low grade. In 1750Abraham Derby started using coal to process iron.

This helped England, in particular, because England was rich in coal deposits. This process made the industries produce steel at a cheap rate. As a coal-mining was dangerous, Humphry Davy invented the Safety Lamp. Miners used this lamp for mining coal in the underground darkness. Thus coal and iron revolutionized the world of industry. The modem age came to be known as the “Age of Iron and Coal.

Question 4.
How were transport and communications – are of Industrial Revolution?
Answer:
With the growth of steam power, the transport and communication scene witnessed corresponding improvements. The British engineer John Macadam started the mode of building ‘macadamized’ roads. In 1814 Sir George Stephenson invented the “Rocke” which was a railway engine driven by steam power: This steam engine ran the first locomotive between Manchester and Liverpool. Steam engines revolutionized navigation and iron ships driven by steam power replaced the old ships of wood.

In 1838 the Atlantic ocean was crossed by two such new ships Ocean travel and maritime trade and commerce came to flourish from then on. The entire communication network came to be helped by the invention of the telegraph in 1835 and of electric telegraphs by Samuel Morse in 1840, Graham Bell’s invention of the telephone in 1876, and Marconi’s invention of the wireless. Thomas Alva Edison invented 187 8 the electric light. The age of electrical most radically transformed the modem world.

England was a prosperous country. For centuries, it was carrying out trade and commerce with other countries. England also had access to plenty of natural resources and materials for herself and her colonies. The shipping industry of England was the biggest and best. The cost of labor was cheap due to the shifting of people from villages to cities. All the city’s reasons explain why the industrial revolution, first, took place in England.

After the machines were invented and came into use, England became the foremost industrial nation in the world within half a century. Between 1813 and 1855 Egland’s textile exports to India increased fifty times, coal production rose by over four times, and pig-iron, over four times. England’s industrial revolution and prosperity came to affect and inspire countries in Europe.

France, Spain, Prussia, Portugal, Holland, and others adopted the industrial revolution and, by the second half of the 19th century, the whole of Europe even the far-away United States of America came to be under its total influence, age of electricity brought more light to human civilization as a whole.

Results of the Industrial Revolution :
The industrial revolution has had no end so far. From machines to electricity to the modem space age of nuclear energy, the industrial revolution is still continuing. As such its results so far can only be studied. Its record so far has been glorious. It has marked a giant step forward for human civilization as a whole.

But while like a flower the industrial revolution has spread its fragrance throughout the world, like a disease it has also infected human civilization. The following analysis of its merits and demerits would show how “Industrialisation was a mixed blessing.

Question 5.
Write the merits of the Industrial Revolution?
Answer:
The merits or advantages of the industrial revolution are summed up as under. Firstly it led to mechanized production. This, in turn, increased production much more than before. Thus, it resulted in improved production, in quality and quantity. This was true of both agriculture and industry. Mass production of goods inaugurated an era of plenty. Secondly, agriculture was to benefit immensely from the industrial revolution.

New tools and machines, steel plow and harrow for tilling, the mechanical drill the planting of seeds, and machines for thrashing, reaping, and cultivating mechanized agricultural production. As such the harvests became bumper and production increased by leaps and bounds with the use of chemical fertilizers. Thirdly, the mass production of goods and articles gave encouragement to trade and commerce.

Transport and communication systems improved with the network of roads and railways. Water transport did not lag behind. Travelling and transportation of goods revolutionized. Europe became one big trading village, with this conquest of man over time and distance. Human mode of life became fashionable and more comfortable with the production of articles of basic and conventional necessities.

Life was pleasant and comfortable, with man’s needs being satisfied more fundamentally and easily. Fourthly, the exploration of markets abroad and beyond the shores of Europe started more seriously. Before shins and navigation helped the process. Internpailade improved. Fifthly; serialization bought urbanization of cities in industrial centers. The inadequacies of village life came with the new urban life. neighbors and gradually demanded political rights.

Trade-union of workers came tip to successfully work for the protection of workers’ rights. Sixthly, the industrial revolution resulted in a contrast. While it came to strengthen capitalism, it also gave birth to communism as propagated by Karl Marx. Seventhly, the growth of science and technology continued unabated. The tire industrial revolution was the greatest blessing for mankind in this regard. The conquest of time brought more leisure, which came to be used for creative purposes.

Question 6.
Write the demerits of the Industrial Revolution?
Answer:
The industrial revolution brought, in its wake, a host of demerits. Firstly, it broke the back of the self-sufficient rural life. The old life style was replaced by a new economic system that brought a virtual end to traditional society. In this transition, artisans of village industry and the peasants came to forfeit their hereditary means of livelihood. Farmers became landless laborers and artisans gave up their ancestral profession to seek means of livelihood in industrial centers.

In a word, the industrial revolution broke the link with the past. People found it difficult to adjust to this transition. Secondly, rural unemployment led to the overcrowding of cities and industrial centers. As such, unemployment in the cities grew. Not everybody can get a job in an industry because the industry would not absorb any laborer over its needs. Increased unemployment led people to frustration.

More availability of labor led to lesser wages. As such the gulf between the rich and the poor widened. This led to class rivalry between the capitalists or the rich or the ‘Haves’ and the laborers or the poor or the ‘Have-nots’. Thirdly, therefore, the industrial revolution made class wars inevitable. Fourthly, the industrial revolution led to capitalism inside countries; but on the international stage, it brought competition, imperialism, and war among the nations.

Fifthly, the industrial revolution made the life of the workers and laborers wretched. Miserable life in the slums of the cities, with no sanitation or hygienic living conditions and exposure to smoke and gas pollution, brought diseases. No grant of leave, no insurance against death by disease or by accident, and the burdens of poverty made their life hell. Sixthly, industrialization brought the political ideology of imperialism into Focus on the international stage and made war inevitable.

From an economic and political point of view, it brought capitalism and communism face to face. It also led to Europe’s colonial and commercial hold over the rest of the world. Thus as a result of the industrial revolution, human civilization came to have a post and materialism came to have a future. The victim was humanism.

Question 7.
State the development of colonial government in England?
Answer:
Meanwhile, certain political changes had come to the fore in England. Queen Elizabeth was succeeded to the throne of England by James I of the Stuart dynasty. James, I was a Catholic and adopted a policy of religious persecution of the Protestants and Puritans of England. The English Puritans, on their part, hated to be brought under the English Catholic Church and decided to leave England to settle elsewhere.

Thus have they come to be known as the Pilgrims. In 1620, they left England from the port of Plymouth fol. North America in a ship named ‘May Flower’. These Pilgrims were known as ‘Pilgrim Fathers’, the ancestors of the modem Americans. They landed at a port that they named as Plymouth in an area to be known as Massachusetts. This ‘May Flower’ voyage came to be followed by many such voyages from England during the reigns of James I and Charles.

The Puritan unhappiness was the principal cause of this exodus. There were certainly other reasons as well. The plight of poverty at home and the promise of prosperity on the fertile lands of the “New World” was under such consideration. Then there was also a zeal for freedom from feudal burdens and the old social system as well. The prospects for living in a free society were also alluring. Thus the English Pilgrims began pouring into America.

The Irish, the Dutch, and people from different German states also came away to America in large numbers. A healthy climate, fertile soil, and an unlimited prospect for prosperity were too tempting. Gradually the English came to settle down in the area permanently. settlements came to be known as colonies. As many as thirteen such colonies came to be established. All these were on the Atlantic Seaboard of North America.

Each colony flourished in its own way, but the procedure for government and administration came to be uniformly based on their English background. The English system of laws and law courts was introduced. Each colony came to have its legislative assembly and a governor. The governor was regarded as the supreme executive authority and was broadly regarded as the representative of the English King. The colonial people came to prosper and flourish. Each colony flourished in its individual way.

Better economic life than their living standards in England led to a sense of pride and contentment. The English Government and people came to regard the thirteen colonies, as English property, because their people had done it. The people of the thirteen colonies had also theoretically accepted it, having made provision for treating the Governor as an agent of the British Crown in a broad sense.

England had thus come to be regarded as the mother country of the thirteen colonies. It was nice of the colonial people to owe loyalty to England, for this was more out of their habit than out of any necessity. The only genuine necessity was with regard to their own security. France had already entrenched herself in her Colonies in Canada, to the north of the thirteen colonies. Fear of a French invasion had led them to owe allegiance to England in expectation of English protection in such contingency.

However, they, later on, came to be discontented with England because of the various manners in which England came to exploit them. The seeds of discontent had come to be sown. The opportunity for their germination came during and after the Seven Years’ War (1756-63) in Europe. In this European War, the English triumphed over their enemies including France. The English captured Canada from France. With the fall of France in Canada.

Die threat of French invasion vanished for the thirteen colonies. Time was now ripe for them to re¬assert themselves. They now decided to break the chains of the English colonial yoke. Discontent spurred them. The ideals of life; liberty and the pursuit of happiness moved them. Many other factors also came to inspire them to rise in revolt against the English.

Question 8.
Write the causes of the American War of Independence.
Answer:
The causes of the ‘American War of Independence were many. The upheaval was a sign that the thirteen colonies had reached such a degree of economic, political, and cultural maturity, that their achievement Of autonomy was inevitable. But it was also a consequence of certain new developments in British colonial policy that provoked the colonies into asserting their independence.

Its causes can therefore be broadly classified into two categories, i.e. the fundamental causes that ignited the spark of discontent and the immediate causes that brought it to a conflagration.

Fundamental Causes:
England symbolized old and traditional institutions like the Church, monarchy, and feudal heritages as well as a general conservatism. On the other hand, ever since ‘May Flower’ brought the ‘Pilgrim Fathers’ to American soil, they had developed a progressive outlook for a society of free men without the bondage of the Church or such other out-of¬date restrictions.

They stood for modem outlook, wherein life, liberty, and the pursuit of happiness were to be the subtle visions. Thus, superior progressive political consciousness tempted them to separation.

Sense of Economic equality and Individual dignity :
Economic equality was a beacon feature of American Society. There was no feudal heritage nor stake. Each was free to develop his economic condition through perseverance and imagination. This spirit came to be described in the 19th century as ‘Social Darwinism’. In the survival of the fittest in human society, only industrious and imaginative individuals can succeed. Each was free and equal, society was thus egalitarian, offering equal opportunity to all and treating all on an equal footing.

Only the Red Indians and the Negroes were the social subordinates as slaves, This emphasis on individual dignity was the source of Social courage and political wisdom. English society, with its hierarchy of Lords, Dukes, the clergy, and commoners, thus came to be looked down upon. Thus, the Americans were only too eager to break the links that chained them to the backward social systems of the mother country.

To these considerations of political, social, economic, and religious differences also came to be added the geographical consideration of distance and isolation from the mother country. The thirteen colonies were thousands of miles away from the mother country. geographical remoteness, at a time when seam-ships and telegraphs were yet to be developed, led to an absence of frequent contacts.

The relationship was thus too formal for a generation of Americans, who were under nothing, except a historical obligation to continue to be loyal to a government hundreds of miles away. Economic grievances of the Americans also added to these sentiments. The commerce of the colonies was regulated by England by virtue of its political authority. It was out of obligation that the colonial people were acknowledging the authority of England over them.

But the English government regarded the colonies as its rightful property because the colonies had been set up by the English. Therefore, England was bent on getting economic benefits out of these colonies. The rules, thus framed, made the American colonies. supply those goods which England did not possess or produce.

pay a part of the English expenses on the army and navy, not to compete with English commerce, and not to grant trade rights to any other country. The colonies felt uneasy under such growing economic burdens. With the withdrawal of the danger of the French invasion at the end of the Seven Years’ War, the Americans were now under no obligation to continue the economic exploitation of them by the English.

Question 9.
Write the immediate causes of the American War of Independence?
Answer:
At the end of the Seven Years’ War, the British government was faced with a grave economic problem. This was because of a business depression after the war as well as an increase in the national debt of England as a consequence of the expenses during the war. The victory was a matter of pride for Englishmen everywhere. British king George III and British Prime Minister Grenville had come to the opinion.

that since the war had been to the advantage of the North American colonies, by freeing them from the French danger, these colonies should help solve some of the economic problems arising out of the war. In the first place, the colonies should assume some of the burdens of their own protection. Total expenses for the defense of the colonies amounted to about 3,00,000 pounds per in.

Second place, they should contribute to the relief of the English Treasury and the recovery of English commerce. It would have been a normal policy under normal circumstances. But the situation had become somewhat abnormal owing to the 1763 proclamation of George III. In that year the British army had suppressed a mutiny of the Red Indians under Pontiac.

The British King, angry that the colonies did nothing to suppress Pontiac, passed this proclamation in 1763, forbidding “all our loving subjects” in the colonies to go beyond a particular point in the western direction. The colonial people regarded this proclamation as deliberately designed to exclude them from the riches of the West. Thus the colonists now came to resent still more keenly the attempt by Parliament to raise more revenue in North America

Question 10.
What are the different Acts and what are their impacts?
Answer:
The first of the new revenue measures, the Sugar Act of 1764, alarmed the American merchants, because it imposed an import duty on sugar, on the colonists. The Stamp Act was passed in 1765. This act imposed a duty on various items including legal and commercial papers, liquor licenses, playing cards, newspapers, calendars, and academic degrees. These duties drained the supply of specie (gold and silver coins) and threatened the colonial economy.

These revenue measures touched off a major controversy. The colonies now boycotted all imports. In 1765 delegates from the thirteen colonies met in New York in a “Stamp Act Congress”. To them, the Stamp Act had a “manifest tendency” to suppress “the rights and liberties of the colonists”. They, therefore, came to argue that as long as they were not allowed to send their representative to the British Parliament to voice their grievances against these high-handed measures of the British government, would not pay these taxes.

Their celebrated slogan now was, “No taxation without representation”. The Stamp Act was withdrawn in 1765 on the appeals of London merchants, threatened by economic ruin, because of the American boycott. The ministry of Grenville resigned. Nevertheless, the Parliament passed the Declaratory Act asserting that the king and Parliament could indeed make laws affecting the colonies.

To King George of England, the Colonies were English property and thus he had the right to rule, control and tax them. In 1767, his government passed the Customs Duties Act (or Townshend duties), levying duties on colonial imports of tea, paper, paint, and lead. Again the merchants of Boston, New York, and Philadelphia organized boycotts. In 1770, British Prime Minister Lord North modified the Townshend duties and made only tea dutiable.

In 1773, the English East India Company attempted to sell its tea in North America. It hoped to overcome American opposition to the hated duty by making the retail price of East India tea far cheaper than that of the Dutch tea smuggled by the colonists. On December 6, 1773, to the cheers of spectators lining the waterfront, a group of Bostonians, disguised as Red-Indians, boarded three East India Company ships and threw the tea chests, worth thousands of pounds, into the sea.

They described this incident as the Boston Tea Party. British government adopted policies to suppress the colonists. The “Intolerable” Acts of 1774 closed the port of Boston and suspended the elections in Massachusetts. This added insult to injury of the “Boston Massacre” when British troops fired and killed some Americans.

Question 11.
What are the implications of the American War of Independence?
Answer:
For Britain, the American revolution brought more severe losses than simply the loss of thirteen colonies. Britain was totally devastated by it. It dealt a great blow to her worldwide prestige and dominance. The Sun has started to set on the British empire. Her international prestige was at stake, particularly after the surrender of armies to the American forces at Saratoga in 1777 and at Yorktown in 1781.

The British used to regard themselves as invincible. The American revolution pricked the bubble of that myth. The loss of American colonies came also as a blow to the power and position of the king, at home. The British King, George III, came to lose the trust of his own people. Even his admirers now became his critics. Before the American war of independence the people of the Thirteen Colonies were regarded as “a race of convicts” who ‘ ‘ought to be thankful for anything we allow them, short of hanging”.

Now public opinion has changed in Britain. The personality and policy of George III came in for severe criticism. In 1780, the British House of Commons passed a resolution that declared that “the influence of the crown has increased, is increasing, and ought to be diminished”. The Prime Minister, Lord North, resigned and was replaced by Pitt, the younger who was a professional politician. He continued in office for long eighteen years and during this entire period, the King was content to play a supporting role to the seasoned Prime Minister.

By far the greatest impact of the American revolution was on international and European politics. During the latter portion of the revolution, France took the stand to isolate Britain in international politics. While its volunteers under Lafayette had joined the forces of George Washington, France came to sign a treaty with Spain (1778) directed against Britain. France also took the lead in Europe to influence other countries against Britain.

Britain stood frustrated, lonely, and humiliated. The American revolution successfully challenged the system of colonialism. All anti-colonial liberation movements that followed in the next 200 years throughout the world drew their inspiration from the American model. American revolution inaugurated an era of democracy and popular governments, All nationalist movements owed their ideals of detente fancy and equality to the American Revolution.

Even, it became one of the immediate causes of the French Revolution. The French soldiers who acted as ‘volunteers’ with the American freedom fighters, returned home and spoke in praise of the better nature of the government and living conditions of the people Ironically, France used Montesquieu’s and Rousseau’s philosophies after the Americans had done so. These two great philosophers belonged to France.

In this regard it can be said that the ideals and ideas of the American revolution influenced those of the French revolution; The American revolution was a national affair w le the French revolution was an event that influenced every nook and comer of Europe and the world. Both were, thus, events of monumental significance for mankind.

Question 12.
What is “Revolution” and what are the political causes of the French Revolution?
Answer:
“Revolutions are not made with rose water” nor are they mere Explosions that announce them – like the first shots at Concord, the fall of Bastille, or the mutiny of the Petrograd troops that signaled the start of the American, French or Russian revolution respectively. A revolution is not an event but a process. It starts in the minds of men and releases a rush of elemental forces in them. A revolution is not made; it comes out of the past and when it comes, it cannot be avoided.

Reform is a correction of the evils and defects, but revolution means nothing less than the complete transfer of power. To quote Edgar Brown, “Revolution means that power must pass from one class to another and even if Bonapartism interrupts the process, a revolution never goes backward.” Thus revolution may be defined as the displacement of the sovereignty of the state. The French Revolution was neither incidental nor accidental. It was in the logic of history and was almost inevitable.

It was a rejection of the past ancient regime; it was a prescription for the future of popular sovereignty. It came towards the end of the 18th century and had already seen the ‘Age of Reason. ’ That is why the 18th century is known as the grave of one epoch and the cradle another. This, the historic landmark was the climax of the enlightenment of the age, for, a revolution always occurs first in the minds of men. Yet, political, social, economic, and philosophical causes also contributed no less to its outbreak.

Political Causes:
Responsibility of Louis XIV Louis XVI and Marie Antoinette :
The Bourbon Monarchy was the root cause of all political unrest in France. The Bourbon dynasty was ruling over France. Louis XIV was the King of France during a long reign from 1661 to 1715. He was fortunate to be the King of France when France was prosperous and the people, were extremely loyal. Feudalism was dependent on royal support. France had no Constitution.

The Parliament of France had not met since 1614. It was not going to meet for 175 years, till 1789. The government was a centralized despotism. All power lay concentrated in the hands of the king. Justice was the hand-maid of the ruler. Louis XIV further consolidated his powers and came to proclaim, “L’etat test ” or “I am the State”. It was a monarchy by “Divine right”, a heritage of the Middle Ages.

The King was regarded as a divine agent, appointed to rule, therefore, the king was only answerable to God, not to his people, for his deeds and misdeeds. Louis XIV was a grand monarch. He was not only a capable general but also a competent builder. He ordered palaces to be built at Versailles, eleven miles from Paris, and he decided to rule from there far away from the dins and bustles of Paris.

Versailles became the dazzling apex of a state edifice that had cost the treasury only 24 million pounds. Versailles was a monument to Louis XIV’s thoughtless extravagance though it was the citadel of his absolutism. The expenditures were unwise, while the seclusion it brought for the monarch from the people, created artificial barriers between the ruler and the ruled. It brought fame to France in Europe, yet it increased the size and volume of French loans from other European Governments.

Louis XIV was a Grand Monarch. His successors were weak. They lacked his personality. So they became unpopular and were too weak to suppress the public discontent. Louis XV was a weakling who could not check the tide of popular disavowal of the growing poverty of the common man and the system of punishment through emergency laws, like “Letter de Cachet” by which a man can be jailed or punished without explanation or trial.

It was already too late, when he regretted, “After me the deluge”. He was succeeded by Louis XVI, in 1774. He was a good man, but a bad king was afraid of taking in dip ’pins of administration and kingship “as if the Universe is falling on me”. “God! What a burden is mine and they have taught me nothing”. “I wish, I could resign too” – reflects his attitude to kingship. He was a kind-hearted man who loved France and her people.

But time had already started blinking at the downfall of the Bourbons. He was a good judge of men and appointed capable administrators like Turgot and Necker. But no one trusted Louis XVI, for his worst shortcoming was that he had no will of his own. Though brilliant, he was unable to exert himself while his wife, Marie Antoinette was under the suicidal bliss of ignorance.

She made luxury the prevailing note everywhere. As gaiety was unconfined, so necessarily was the expenditure that kept it going. Wilful wastes thus paved the way for woeful wants. Expenditure was larger than income and foreign loans were sought to keep the machinery going. The total palace expenses f<?r 1789 alone were more than 20 million Francs.

The royal court was the tomb of the nation. Thus, despotism was changed to its own misdeeds and could not escape their consequences. The Parliament or ‘States General’ had not met for 175 years. Public appointments continued made by nomination rather than merit. Privilege, not law, was the basis of the state; expedient, not principle, the principle of its rulers.

Question 13.
What are the social causes of the French Revolution?
Answer:
The Third Estate:
Like the monarchy itself, the social and economic foundations of the old me were beginning to crumble and slip by the middle eighteenth century. French society was divided into three traditional classes or ‘estates’. They were the nobles, the clergy, and the common people. The nobles and the clergy were the first two estates and the common people were the ‘third estate.’

The first two estates were the aristocrats who enjoyed all powers and privileges and were exempted from paying any tax to the State. Only the third estate paid taxes of various kinds because they did not enjoy privilege and bore the brunt of the wrath of the privileged aristocracy. They paid the ‘Taille’ or land tax, ‘Vingtieme’or income tax, ‘Gabelle’ or salt- tax, and Corvee’ or road tax. Apart from these, they paid ‘Tithe’ to the Church and feudal dues to the nobles. Discontent grew at these disparities.

The peasants and common people were thus groaning under the oppressive burdens of taxation, poverty, and punishment by the King through ‘Letter de cachet’, by the nobility through coercion, and by the Church through persecution. The peasants were the worst suffers. To add to their misfortune, there had been the famine of 1788, as a result of which “one-third of them had nothing but third-rate potatoes to eat, for one-third of the year – in the words of Carlyle.

The King had no time or inclination for them, “Wha is the Third Estate ?” asked Abbe Sieyes and answered, “Everything, what has it been in politics until now? Nothing. What does it desire? To become something.” The picture of the society was described in a famous way, “the nobles fight, the clergy pray, the people pay.” The Nobles and the Clergy “The revolution of 1789 was much less a rebellion against despotism than against inequality.”

The nobles and the clergy constituted one percent of the total population of France. The institution of nobility had been a feature of society since the days of feudalism. When the strong monarchy was revived, the institution was not abolished; rather the volume of its vices of exploitation had gone up. They continued to enjoy their rights, while they continued to forget their obligations to the State and people.

They continued to receive their feudal dues from the people but did not pay their taxes or dues to the State. The clergy did not lag behind the nobles. The clergy possessed estates, collected tithe from the people, threatened persecution and the Church was autonomous. The government had no control over Church or religious affairs. The Church was thus “a State within a State.” While superstitions grew, so did religious exploitation.

Gradually the intelligentsia took up the gauntlet against the Church and clergy, exposed and criticized them, and exhorted the people to rise n rebellion against in clergy. Holbach, an intellectual of the age, lamented, “Religious and political errors Have turned the Universe Into a valley of tears.” “The French Revolution was a general mass movement of the nation against the privileged classes”, said Napoleon Bonaparte.

No man could have held back those social forces, setting the dimensions of the new era. Thus, the national discontent led to the prominence of the middle class or bourgeoisie. The revolution was bourgeoisie in origin, character, and climax. The middle class is the backbone of any society. They are educated people belonging to various professions.

They were the seat of revolutionary spirit. They criticized the existing vices, promoted discussion, roused passion, and led the people to believe that the only limits to the realization of a better tomorrow were the doubts of today. The middle class became the vanguard of the revolution.

Answer:
French society was characterized by various economic imbalances. The nobles and the clergy constituted one percent of the total national population. They owned forty percent of the total national wealth. They did not pay any tax by virtue of the convention of privilege. This created inevitable bitterness because the unprivileged class bore the brunt of taxation.

Short Notes on :
Montesquieu :
Foremost of these philosophers was Montesquieu (1689 – 1755). He was a lawyer by profession. This French philosopher set out to analyze political virtues. In 1748 was published his great work, ‘The Spirit of the Laws. This work was to initiate a philosophic movement against the ‘ Old Regime. ’ The work was not a figment of fiction nor a flight of fancy.

To Montesquieu, liberty is the ultimate objective of all reason or rational processes. Liberty was impossible v without, what he called, the separation of powers. The legislative, executive, and judicial ‘ powers of a State should be in separate hands. Each of these three branches should be as powerful as any of the other two. No two such branches should come together.

Thus, the government can run smoothly through this system of checks and balances. Thus, through the ‘Separation of Powers’, public liberty can come, not only to be granted but guaranteed, as well. When “The Spirit of the Laws” came to be published, it was in such heavy demand that there were 22 editions of this book in only t eighteen months. It awakened a taste for ’ political studies by bringing social sciences into the focus of literature.

It was a challenge to the Monarchy of France because by wielding all legislative, executive, and judicial authority of the State, the Monarchy was denying liberty people. Montesquieu, thus, inaugurated the attacks of philosophy and reason on the ‘Old Regime’ and its vestiges in France.

Voltaire :
Another philosopher, though in a different mold, was ‘King’ Voltaire. He was one of the masterminds of Europe and his age (1694-1778) is known in the history of Europe as the ‘Age of Voltaire’. This philosopher was famous for his wit and wisdom. He preferred to be ruled by one lion than by a hundred lambs. Yet he was for benevolent despotism. This controversial philosopher was therefore adored by Catherine the Great and Frederick the Great in their respective courts.

But Voltaire was against weak despotism and called upon the people to rise in revolt against weak rulers. The people affectionately described him as ‘King’ Voltaire. Voltaire vehemently opposed to the corruption in the Church and called upon the French people to “crush the infamous thing”. Voltaire was “a pillar of cloud by day and of fire by night.” Tyranny of any form was opposed to him. The French took up his advice as a mandate to strip the Church of wealth and power.

Rousseau:
But if any philosopher deserves singular credit for having fathered the French Revolution, it was Rousseau (1712 – 78). His ideas inspired the radicals of the French Revolution. He started with a sweeping generalization, very typical of the Enlightenment. Whereas nature dignifies man. Rousseau argued that civilization corrupts him; man would be corrupted less if civilized institutions followed nature more closely.

This was the central theme in “Emile”, in “Discourse on the Moral Effects of the Arts and Sciences ” as well as in his masterpiece “Social Contract” (1762). “Man is born free and everywhere he is in chains” Rousseau regretted. He, therefore, urged the people to rise in revolt against the oppressive tyranny of their despots, “sweep away all the false fabric of society.

the world of ugly wants and insolent riches and establish ‘felicity of life’ by destroying the serpent of property. Iron and com had a civilized man and thereby ruined mankind. The simplicity of ancient ways of life was destroyed by the concept of property. Rousseau raised the clarion call of “Liberty, Equality, and Fraternity”. The French Revolution of 1789 adopted the call as its swan song. Rousseau was a champion of liberty.

“Better the perils of liberty than the privileges of servitude”. Rousseau was an egalitarian society without distinctions of class or status. He stood for the universal brotherhood. Rousseau attempted to harmonize government and liberty through the theory of the social contract. While earlier theories postulated a political contract; Rousseau’s contract was social, where a whole society agreed to be molded by its ‘general will’.

Rousseau was an advocate of democracy and individualism. His idea was a free citizen in a free state His ideal State was a republic virtue’. His philosophy breathed “revolt in the name of nature, against the artificial social system” in France. It also inhaled the sweet breeze of virtue and ‘Liberty, equality, and fraternity.’Thus Rousseau gave the future revolution, its own philosophy, creed, its purpose, and its direction.

He was true, the Father of the French Revolution, though he had died eleven years before its outbreak. Apart from Montesquieu, Voltaire and Rousseau, there were other intellectuals, philosophers, and encyclopaedists who also prevailed in the French mind. Diderot and the other encyclopaedists gave the synthetic knowledge of ages to the French and thereby started discussions and aroused passion.

among other things, popular sovereignty. Helvetius projected “the self-interest” of man and society. Holbach criticized the Church, D’ Alembert, Quesnay and others inspired the French people with their writings.

Long Questions With Answers

Question 1.
What are perception and its operational benefits? Discuss the process of perception. Meaning and Operational Definition.
Answer:
While interacting with the environment, the organism is impinged by a number of stimuli, lie receives these stimuli through its sense organs. This is called sensation. The sensation is the raw material of experience. When meaning is added to the sensation, with the help of past experience and learning it becomes perception.

In other words, perception provides meaning and awareness to a particular sensation. The sensation is mere acquaintance with the stimulus. But perception contributes a clear knowledge about the stimulus. So perception has been included under the cognitive (knowing) aspect of the mind. Perception has become the meeting ground of experimental, clinical, and social psychology.

Starting from Wundt to Gestalt perception has been a topic of great interest. Watson, Wundt, Titchener, and Gestalts, all gave due importance to the process of perception. Gestalt School dominated the study of perception for the next two decades. Their research centered around the organization of perception.

As already pointed out, perception contributes meaning and awareness to a particular sensation. For instance, you see a big bird-like object flying in the sky. This is the sensation when you attend to it and say that it is an airplane, it becomes perception. Perception is, therefore, defined as the awareness of sensory stimulation.

But this is an incomplete definition. Along with awareness, the most important thing in perception is adding knowledge and meaning to this awareness, i.e., interpreting it on the basis of past experience. Perception is, therefore, defined as the interpretation of sensation in the light of past experience.

When a person faces a stimulus, he gets a sensation. It may be a sensation of vision, smell, or sound. When he tries to go ahead and add knowledge to this sensation with the help of experience and learning, it becomes perception. Titchener has defined perception as a complex of sensory and imaginal elements.

By this, he implied that perception is always built up of complex experiences out of sense impressions, characteristics, and qualities supplied by mental activities. According to Hebb, it is a process of information, extraction, and preparation for response. This definition of Hebb emphasizes the selective nature of perception. We do not perceive each and every stimulus. We perceive the one which we select to perceive.

Processes involved in Perception:

The mechanism through which the organism converts a sense of impression to perception by adding knowledge and meaning to it is called the process of perception. Thus, the sensation is the first step in the process of perception. Perception, in fact, starts with sensation. Though without sensation there cannot be any perception, all sensation may not lead to perception, because perception is a selective process.

According to Munn (1954), “The term perception is customarily used to refer to relatively complex receptors or neural processes which underlie our awareness of ourselves and our world. This awareness is referred to as perception. “Perception is, therefore, a very complex process.”

As mentioned earlier at a given moment We get a number of sense impressions from the environment around us. But it is neither possible nor necessary to perceive everything at a time. So our perception at a given moment is based on selection. Selection is guided by set, need, or by objective determinants of the stimulus.

Needed objects are perceived first. A large number of studies on perceptual selectivity lead to the conclusion that there are certain objects in the environment that conform to the current needs, values, attitudes, and past experiences of the perceiver and hence are selected for perception.

Titchener has explained perception as a selective act in terms of attention as attention is a preperceptive attitude. The selective manner in which different part systems are analyzed in perception is largely determined by the unique interaction between the individual and his cultural media, which he has passed through and of which he is a part at the moment.
After selection one starts perceiving.
This process of perception involves:

  • Receptor Process
  • Symbolic Process
  • Affective Process

In each act of perceiving, these three processes are involved.
Receptor Process:
Perception not only depends upon the mental set but also upon the forms of stimulation, the receptor functions, and the neural functions. Simultaneously different receptor processes like visual, auditory, olfactory, gustatory, kinesthetic, and neural are activated. At a particular time perception is limited only to a particular receptor process.

For instance, at the same time the telephone rings, and the calling bell rings. Here you receive both sounds through your auditory receptors. But you cannot attend to both simultaneously. So you decide to attend to the tclephni1; call first and then the calling bell.

Symbolic Process:
Sensory stimulations arouse certain neural activities which have their trace in the nervous system. These are popularly known as neural traces. These traces act as symbols or substitutes for the original stimulus or experience. There are called images. When the teacher, for instance, asks the student in the class to draw a picture of his father in his mind’s eye, it becomes symbolic.

These symbolic images help us while perceiving something. This symbolic process is activated by any experience or image associated with the father. It is called symbolic because it represents some experiences or images, as it stands for some experiences or images which is a necessary part of the perceptual process. While sensations depend upon the present, images are derived from past experiences.

For any perception both present sensation and past experience in the form of images are necessary. Perception, therefore, does not consists only of sensation or only of images. It is made up of sensations, ideas, and images. All these come simultaneously at the same moment to make perception complete. Particularly, for adding meaning and knowledge to their interpretation of a sensory experience, the symbolic process helps.

Affective Process:
When we are perceiving an object, with receptor and symbolic process, the affective process is also involved to complete perception. In fact, an effective process forms an integral part of the process of perception. When one is interpreting a fruit, say a mango, it may appear to him pleasant or unpleasant or it may bring an indifferent neutral feeling in him.

This pleasantness or unpleasantness for the percept (the object which we perceive) may arise due to past experience or due to the very nature of the percept. Say, you like the mango as it is sweet. So its presence brings a pleasant sensation in you. The fragrance of a flower always gives a pleasant sensation. The bitterness of quinine always creates an unpleasantness.

Such ideas about the percept are not due to past experience only, but because of the very nature of the object. But in most perceptions, the affective feeling is determined by past experience. You don’t like the sight of a particular person or females on the whole. You cannot stand the sight of jasmine because it reminds you of a very painful memory.

Individual differences in the perception of the same object are mostly guided by this affective process, perception is an active process as pointed out by Ruch (1970), “perception is a process whereby sensory cues and relevant past experience are organized to give us the most structure, meaningful picture possible under the circumstances.”

Question 2.
What is attention and what types of attention?
Answer:
Attention is also described as selective and fluctuating. At a particular moment, so many stimuli around us attract outs attention and draw our awareness. But we Only attend to that stimulus that suits our purpose at the moment. So, we select only the stimulus at a time and reject the rest. When you enter the drawing room of your friend, the beautiful personal carpet immediately draws your attention because of its fantastic color combinations. You at this moment, only select to attend this and it remains in the center of your consciousness for some time.
Types of Attention
Attention has been classified in 3 groups:

  • Voluntary Attention
  • Involuntary Attention
  • Habitual Attention

Voluntary Attention:
Voluntary attention also called effortful attention. When attention requires special effort on the part of the attendee to attend it, it is called voluntary attention. In this case, we attend an object that we really want to attend. At the time of examination, a student has to attend to a particular topic if he comes to know that questions have been set from this topic.

Involuntary Attention:
When without one’s own effort one attends to a stimulus it is called effortless or involuntary attention. Munn (1954) remarks that “when stimuli or situations force themselves upon us as it were, whether or not we are set for their perception, attending is said to be involuntary.” In voluntary attention, stimulus draws our attention because we can not help attending.

In voluntary attention usually occurs because of the quality of the stimulus itself, either loud sound, eye-catching color, or the huge size of the stimulus object. As opposed to voluntary attention involuntary attention is incidental. There is more fluctuation and greater distraction in involuntary attention since the desire to attend is very less in this type of attention.

Habitual Attention:
We attend to certain objects in our environment because we have been attending to these stimuli from the very beginning. So just out of habit and past experience, we attend to it not by pressure nor out of the will, rather because of continuous observation of these stimuli we become habituated to attending them.

The gardener attends to the plants, the housewife attends to the kitchen, the mother attends to the baby and the student attends to his study, because of habit. In a similar way, a smoker attends a cigarette shop, and a painter’s attention is drawn immediately to beautiful paintings. The doctor’s husband attends to the telephone call and the mother attends to the baby’s crying.

In habitual attention, the person is permanently set for the reception of certain stimuli. Let us take the example of a husband chess player, who purchased a book on ‘Chess’, a wife who was interested in cooking and purchased a book on Chinese recipes, and finally, a daughter who is a cricket lover, who purchased a book on cricket. Thus, in habitual attention, internal conditions and bit play a major role.

In habitual attention, the attitude of alertness develops which determines one’s attention to a particular stimulus. In the words of Munn, “Most of our acts of attending are continuing rather than abruptly assumed sets and they are sets of which we are frequently unaware. These continuing sets stem from our motives. They are related to drives, interests, attitudes, prejudices, and aspirations”.

Habitual attention may develop out of voluntary attention. In the beginning, you may start reading, cooking, or gardening because of necessity, out of your own will. But once you are habituated to doing it, it becomes a part of your life and you cannot give up reading daily to it. A student who was habituated to reading daily for four hours used to read daily even after he passed his MBBS Examination.

Once when this author asked him “Why are you studying daily, going to the library ? You have already passed. Take some rest”. The boy remarked, “I can’t sleep peacefully unless 1 read daily and go to the library. It has almost become a habit with me.” The present author who has cooked for the family for the last thirty-five years, now it has almost become a habit with her to attend to cooking.

Question 3.
What are the various determinants of attention? Explain objective determinants in detail.
Determinants of Attention
Answer:
The complexity of the environment makes the individual face so many stimuli simultaneously at a given moment. But as it is impossible to attend to all at a time, he selects one of them. What are the conditions for selecting a particular stimulus for attention? What are the factors that make stimulus attract our attention? Why do we select one and reject the others? All these questions deal with the determinants of attention. Many factors influence the direction and selection of our attention. They determine our attention.

The determinants of attention may be classified under two broad heads:

  • The objective or external determinants.
  • The subjective or internal determinants.

A large number of researches in consumer psychology, in the area of advertisement and selling, have uncovered several external and internal determinants.

Objective Determinants:
Those factors or determinants which lie in the stimulus or object of attention are called the external or objective determinants. They are the qualities and characteristics present in the object of attention. They are:

  • Intensity
  • Size
  • Duration
  • Novelty
  • Repetition
  • Change
  • Systematic form
  • Movement
  • Location
  • Colour
  • Contrast
  • Prepotency

More often than not, several of these factors operate together in determining our attention at a given moment.
Intensity:
The more intense the stimulus, the more likely it is to be attended. It is also called the potency of the stimulus. The sound coming from the loudspeakers, deep and bold colors, bright, gorgeous shades, strong, fragrance, severe pain, all these draw attention immediately. On the other hand, a soft whisper, low sounds, plate color, and fade shades, and dim light do not catch our immediate attention, keeping other words constant.

The brilliantly lit signs in front of the traffic stand or cinema hall attract our attention to those than the low power lights. Thunder draws our attention at once. According to Boaz (1984) here the selection depends upon the very nature of our sense receptors and on the greater amount of energy stimulated.

Size or Extensity:
The size of a stimulus is of great importance in determining the direction of our attention. Big things always draw one’s attention more than smaller ones, other things being equal. A big poster, a big elephant, a big mouse, a full-page advertisement, and big letters draw instant attention in comparison to their smaller counterparts.

For successful advertisements very big posters and big lights are kept in front of shops. During elections in India, the full-page advertisement of hand, the election symbol of Congress (I), drew the immediate attention of a large number of people. Thus, the greater size of the stimulus has an advantage over smaller sizes. However, size is only one among the diverse factors determining one’s attention.

Duration:
Other things being equal, objects exposed for a longer period of duration have greater attention-catching value than those shown for a shorter period. When a card containing a few digits is exposed before us for 1 minute it is better attended than when it is exposed for only 1/10 part of the second. Similarly, a sound or a visual exposed for a moment obviously escapes our notice while the one which persists catches and holds our attention.

But the stimulus presented for a continuous duration is less likely to hold one’s attention because of fluctuations than the stimulus which is presented at intervals and for a moderate duration. For example, if the noise goes on without break it might escape our attention. The duration of exposure hence should be up to a limit.

Novelty:
Most of us attend to anything that is novel. Things to which we are unaccustomed, which are new to us, whether sound, smell or taste, are instantly noticed by us. That is why, anything strange or unusual has always a unique charm for the attending person than the things which are conventional, traditional, ordinary, and usual.

Say, for instance, a newly designed unusual dress used by a girl may draw our immediate attention to her more than when she is dressed in a traditional saree or salwar kameez. Similarly, strange animals, ultramodern buildings, unusual colors, strangely decorated drawing rooms, and novel flower arrangements draw our attention more than conventional ones. Novelty in the technique of advertisement on T. V., Radio draws a lot of attention.

Repetition:
According to Ruch (1970), “A work stimulus frequently repeated may be as effective as a strong one presented once.” Thus, a stimulus may not be very intense or colorful, it may not be very big in size, and the sound may not be very loud, but if it is repeated over and over again it may eventually draw our notice.

Repetition brings the object to the center of consciousness and so we are bound to attend it. When you are studying and somebody gives knocks on the door, you overlook it. But if the knock is made repeatedly over and over again, you are definitely drawn to it. But there is a limit to the effectiveness of repetition.

If it goes beyond the limit, it ceases to draw one’s attention just like diminishing returns. If repetition is overdone it can also lead to monotony and unpleasantness. For instance, the continuous and repeated ticking sound of the timepiece kept on the study table escapes our attention though it is there in the fringe of our consciousness. This is because we are so adopted or accustomed to it.

Question 4.
What do you understand by errors in perception? Explain some geometrical and fan’s Zollner, height width, Ponzo, and Jastrow illusion.
Answer:
Errors in perception Always our sense organs do not provide correct information. So we can not always rely upon these sense organs. Very often what we see and hear may be wrong and misleading. We perceive certain things which are not actually present there and sometimes we perceive one thing for another.

On the whole, our perception of the stimulus world may not be always accurate. The sensory information may be incorrectly interpreted on certain occasions. These are called errors in perception. Mainly two types of errors are there – illusion and hallucination.

Illusion:
Illusions are the wrong perception while perception is the correct interpretation of sensation, illusion is the wrong or mistaken interpretation of a sensory experience. In both perception and illusion existence that is illusion always has an apparent external stimulus. A person suffering from a severe cold may not get the real fragrance of flowers or the smell of fish. Thus the errors in perception seem to be a function of diverse factors.

Muller Lyer- Illusion:
It is also known as a geometrical illusion. An observation of the diagram given below would lead to every normal person saying that the horizontal line ‘A’ looks smaller than line ‘B’.

What do you understand by errors in perception Q4

But actually both the lines are of the same length. Muller and Lyer, two psychologists, observed this kind of error in perception for the first time and hence called it Muller Lyer Illusion. In this visual illusion, both lines are of equal length. At the end of line ‘A’ two very short lines are joined just like an arrow and at the end of line ‘B’ two very short lines of the same size as line ‘A’ are joined like a feather.

These two are known as arrow-headed and feather-headed lines. Though both lines are of similar length the feather-headed line appears invariably longer than the arrow-headed line. It is a universal illusion as this error in perception takes place in every normal person due to the stimulus factor.

Even children old enough to express their nature of experience and some animals react in the same way as normal adults. Perception of the comer of buildings, and rooms is due to this type of geometrical illusion. Hering illusion, Zollner illusion, and Orbison illusion are some of the examples of geometrical and optical illusions universally found.

Hering Illusion:
It is named after Hering (1861). In the following figure, the two horizontal lines are parallel. The distance between 1 and 2 is the same, all the way across the figure. But they appear every one as unparallel. This is also called Fan’s illusion.

What do you understand by errors in perception Q4 1.1

 

Zollner Illusion:
It is named after Zollner (1860). All these lines are drawn in a parallel way. But they are not perceived as parallel.

What do you understand by errors in perception Q4 1.2

Height Width Illusion:
A tall hat is put in a short vase. The height and width of the hats are equal. But one looks taller than the other.

Ponzo Illusion:
It is also a geometrical illusion. Circles 1 and 2 are really of the same size. But circle 2 looks bigger than 1.

What do you understand by errors in perception Q4 1.3

Jastrow Illusion:
The two crescents 1 and 2 are of the same size but 1 appears to be bigger than 2.

Question 5.
Define perceptual constancy. Perceptual Constancy
Answer:
The tendency of the percept to remain the same from moment to moment and from time to time refers to the constancy of perception. Even when we perceive an object under different conditions, size shape, and height, the perception of the stimulus does not change. It remains the same. Thus, in spite of the constant changes in the stimulus field, the stimulus situations that are familiar are easily recognized for what they are. Perceptual constancy includes the constancy of size, shape, distance, color brightness, etc.

Size Constancy:
The size of a stimulus varies with the change in distance in distance between the percept and the perceiver. A tree that is usually perceived at a distance of 5 feet will look very small when perceived from a distance of 30 feet. This is because the size of the retinal image becomes smaller and smaller as the distance of the object from the eye becomes larger and larger.

But in spite of this significant difference in the sense of impression, we perceive the tree to be of its usual size. Similarly, from whatever angle you perceive a square table, you will perceive it in its actual size. Martin did an experiment on size constancy. A series of 13 blocks were lined up from the observer varying in size from 30 mm to 90 mm.

The standard blocks, one at a time, were placed at varying distances from the observer, but always nearer to him than the comparison series. The technique again was to have the observer select the blocks that appeared equal in apparent size to the standard. Considerable constancy was indicated by the observer in the perception of the size of the blocks.

Colour Constancy:
When a black paper is brought from the dark comer of a room into direct sunlight by a window, the intensity of the sunlight being reflected from its surface is increased. The paper is still perceived as black, and the perception of the color of the paper does not change though the conditions against which it, is observed are radically changed.

When a blue paper is placed in yellow illumination of the optimum intensity and observed through a reduction screen it appears neutral grey. But when observed without the screen it appears as blue because in yellow constancy illumination is perceived as blue. Cramer has shown that well-known objects projected into an obviously colored screen, retain their object colors.

Shape Constancy:
We perceive a circle as a circle or a triangle as a triangle though it appears to be of different sizes from different angles. A circle may appear of an oval size from a particular angle, but we perceive it as a circle though referral images vary from angle to angle and position to position.

Brightness Constancy:
Under brightness constancy, a known object is always perceived as having the same color even if the conditions of illumination are quite different. Always the sense impression of the refer a very with the conditions of illumination that is dim, bright, average, etc.

Question 6.
Define illusions and illusions caused by stimulus factors and illusions of movement and moon illusion.
Answer:
Illusions- are wrong perceptions while perception is the correct interpretation of sensation, illusion is the wrong or mistaken interpretation of a sensory experience. In both perception and illusion, the sensory experience of a stimulus has real existence that is illusion always has an apparent external stimulus. In perception, the sensory conventional example of an illusion is taking a “coil or roope or rope for a snake in darkness”.

Illusions are misperceptions resulting from misinterpretation of information received by our sensory organs, illusions are experienced by all normal human beings, third, and animals. They are experienced through the stimulation of any of our senses. It is true that our perceptual process involves the organic and functional factors for the interpretation of a particular sensory experience.

Perceptual Process:
According to Morgon and King, “An illusion is not a trick or a misperception. It is a perception that does not agree with other more trustworthy perceptions. Illusions demonstrate that what we experience depends upon processes which go far beyond the sensory input.” Thus, a well-defined and very similar stimulus may lead to an illusion undo-certain circumstances, but not always.

As already discussed, our perceptual process involves the organic and functional factors for the interpretation of a particular sensory experience. In other words, we interpret a stimulus in the light of our past experience, organic needs, values, attitudes, motives, etc. If this interpretation is incorrect, we perceive the stimulus wrongly and commit mistakes in our perception.

Errors in perception are not very unusual and every individual is likely to commit errors in his perception in his day-to-day life. These errors mainly depend upon the physical and psychological conditions and circumstances under which the stimulus is interpreted. Illusions may be categorized under different heads on the basis of their causes.

Illusions due to organic and functional factors also occur due to defects in the sense organ of the perceiver and limitations in the receptors. Award-hearing persons or partially blind or colorblind persons may be liable to many illusions. Mental deficiency and emotional states also affect the accuracy of perception. Perception becomes distorted and is misinterpreted under highly disturbed and emotional states.

Illusion caused by Stimulus Factor:
Horizontal, vertical illusions occur due to the stimulus factor. Suppose we take two straight lines of 3 cm each. The first line we draw horizontally exactly from its middle point (1.5 cm):

Define illusions and illusions caused by stimulus factors and illusions of movement and moon illusion Q6

We draw another vertical line of 3 cm (the second line). Now observe both lines, the vertical line is observed longer than the horizontal line. This type of illusion is caused due to stimulus factors. Certain illusions also occur due to personal or functional factors like need, value, past experience such as observing the colored balloons as fruits.

Take another case. You have gone to the station to receive a friend. You call somebody else your friend from his back. This is an illusion due to expectations or mental set. A color-blind person cannot perceive the real color of a stimulus or a hard-hearing person may consider the sound coming from a truck as the sound coming from a scooter.

Define illusions and illusions caused by stimulus factors and illusions of movement and moon illusion Q6 1.1

The illusion of Movement:
When an observer perceives a moving picture when actually the object is not moving it is called an illusion of Movement. This is also known as Phi-phenomenon named by Gestaltist Wertheimer. In Movies, T.V. screens, and electrical advertisements this illusion of movement is noticed.

What exactly mean? When a number of still pictures are projected one after another at a suitable rate, say for a fraction of a second, we see the picture moving though actually, they are static, still pictures. Take an example, you are traveling in a fast-moving train. You find the trees on both sides moving, though actually, they are static. This is also an illusion of movement.

Moon Illusion:
It is an example of the size constancy illusion. Hochberg writes, “It has been known as everybody the moon looks quite large when it is near the horizon than when it is overhead at its zenith even though the visual angle subtended by the moon remains constant”. Recent research on the Moon illusion has supported an ancient explanation.

The earliest explanation for this moon illusion has received some experimental support to argue that: “the sky at the horizon looks further away (due to the intervening fortress and thus the moon seems larger near the horizon.” (Kaufman and Rock). Thus, the distance is taken into account while judging the size of the object.

Question 7.
What is an illusion? Discuss briefly the various theories of optical illusion and Hallucination
Answer:
Although our perceptions are usually quite accurate, they are also subject to distortions called illusions. So these are wrong and incorrect perceptions. Here external stimulation is always present illusions are mistaken or wrong interpretations of sensory experiences. In the true sense, these are not perceptions.

Because in perception, the stimulation is correctly interpreted. Whereas, in illusions, the stimulation is wrongly interpreted. It is obvious that the experience depends upon the process. In short, illusions are misperceptions resulting from misinterpretation of information received by our sensory organs illusions are experienced by all normal human beings, birds, and animals.

They are experienced through the stimulation of any of our senses. It is true that our perception process involves the organic and functional factors for the interpretation of a particular sensory experience.

Theories of Optical Illusion:
Several theories have been developed to explain the causes of optical illusions, and they are discussed here briefly.

The Eye Movement Theory:
According to the eye movement theory, optical illusions sometimes occur if the eye movements are blocked due to the inward projection of other lines. This theory explains the Muller-Lyer Illusion.

The Perspective Theory:
It argues that everyone knows that distant objects appear smaller in size than nearer objects. The perceiver thus compensates for such learning even though they may be equal. Thus, he perceives the objects at a distance to be greater in size than the nearer ones.

The Confusion Theory:
The perceiver observes the percept as a whole, as one unit, and does not analyze it fully. It has been found that if the Muller-Lyer Illusion is analyzed by narrowing down over a range of vision, the illumination would be greatly reduced.

Good Figure Theory:
As a natural tendency, we eliminate the irregularities in a particular figure and fill up gaps to give it a complete meaning. We want to see the figure as a single, meaningful and compact unit. This leads to illusions. It has, therefore, been concluded that illusions like constancies are the natural products of certain factors like need, value, mental set and post experiences, etc. functioning in a given physical environment.

Hallucination:
It has been already discussed how the illusion is a normal affair. Most normal people sometimes or others experience the illusion. But hallucination which is also a type of perceptual error is experienced by mentally disturbed abnormal persons. It is also experienced by those who are under the influence of drugs.

Illusions always have an external stimulus. In hallucination, there is no real sensory stimulus or apparent objective external stimulus, but we perceive it as some object or figure and demonstrate experiencing a hallucination. For instance, when we visualize a ghost every night when there is none when we hear a huzzing sensation inside the stomach.

When there is no such sensation or when we experience severe pain when there is no pain sensation at all, we experience visual, auditory, and tactual hallucinations respectively. Hallucinations may be visual, auditory, olfactory, tactual, gustatory, etc. But usually visual and auditory hallucinations are more commonly experienced.

Hallucinations represent our inner conflicts, fears, anxieties, and mental imbalances. Particularly, in certain forms of insanity like Schizophrenia, hallucination forms a major symptom. Sometimes such patients hear the voice of God, and spirit and are found to actually talk with them in their imagination. Especially common are auditory hallucinations.

Question 8.
Critically examine the role of the organization in perception.
Answer:
Perceptual Organisation:
Very often we are confused. How does perception work? This question has long fascinated psychologists and philosophers, who have generated many theories to explain the key functions and operating principles of perception. Two prominent explanations are there:

  • Experience-based influence and
  • Gestalt Principles of Perception.

The experience-based inference was the dominant approach established by Hermann. Von Helm Holtz (1966). Helmholtz argues for the importance of experience in perception. According to his theory, an observer uses prior knowledge of the environment to make sense of the proximal stimulus. His theory proposes that we learn how to interpret sensations on the basis of our experience with the world.

But in the early 1.920, Gestalt psychologists maintained that psychological phenomena could be understood only when viewed as organized, structured wholes and not when broken down into primitive perceptual elements. The German word ‘Gestalt’ roughly means form, whole, or configuration. It challenged the views of structuralists and behaviorists by arguing that the whole is more than the sum of its parts.

Gestalt psychologists first study several aspects of perceptual organization systematically. Perceptual organization is the process by which we structure the input and create perceptual coherence. In other words, the perceptual organization puts sensory information together to give us the perception 6f coherence. Many of the organization processes we will discuss in this section were first described by Gestalt theorists who argued that perception depends on the laws of the organization or simple rules by which we perceive shapes and forms.

The organization of sensory data is the beginning of the perceptual process. We will have a confusing world if we do not put together and organize the information available to us through our millions of receptors. Max Wertheimer, Kohler, Koffka, and other Gestalt psychologists have studied and experimented on perceptual organization extensively.

They have discovered a number of principles relating to the organization of perception. According to these psychologists, an individual organizes a multitude of environmental stimuli into meaningful structures and forms. Always a person perceives patterns of stimuli rather than random collections of individual stimuli.

An individual integrates disconnected parts of sensory information into a meaningful structure, which ultimately results in the perception of a whole. So the perception of an object or event is something more than the sum total of its sensory input. To bring out a clear picture of the perceptual process, Gestalt psychologists have discovered a set of principles, which are popularly known as Gestalt laws of perceptional organization.

The Gestalt Laws of perceptual organization are based on three groups of principles:

  • Laws of grouping
  • Figure-ground relationship and
  • The goodness of figures.

Laws of Grouping
Generally, the laws of grouping propose how certain elements in the perceptual field of an individual go together. The following are some important principles of grouping.
The Law of proximity (Nearness):
Very often, elements may be grouped according to their perceived closeness in time or space. In short, elements that appear together tend to be grouped together. Now see the figure below. Here eight lines are seen as four pairs of lines.

Critically examine the role of the organization in perception Q8

Here, a very pertinent question is – how does our visual system accomplish this perceptual grouping, the perception that sets of stimuli are together? The perception of stimuli as ‘grouped’ was first studied extensively by Gestalt psychologists. Max Wertheimer (1923). He presented subjects with arrays of simple geometric figures.

By varying a single factor and observing how it affected the way people perceived the structure of the array, he Was able to formulate a set of laws of grouping including proximity. According to Wertheimer, all else being equal, the nearest (most proximal) elements are grouped together.

The Law of Similarity:
Our tendency to perceive things are belonging together because they share common features reflects the law of similarity. This law proposes that with the proximity among elements being equal, perceptual elements that are similar in some respect tend to be grouped together.

Critically examine the role of the organization in perception Q8 1.1

In the above (Fig. 5.3), you see rows of triangles, squares, and circles rather than a column consisting of a triangle, a square, and a circle. In the figure, you observe triangles go with triangles, squares with squares, and circles with circles. Since there is a uniform distance between triangles, squares, and circles; therefore, the law of proximity does not occur.

The Law of Good Continuation:
This principle suggests that elements that appear to follow a particular direction, such as a straight line or a simple curve are readily perceived as forming a group. It is just a tendency to perceive stimuli as a part of a continuous pattern. In the figures below, you see a zigzag line with a curved line running through it, so that each line continues in the same direction it was going prior to the intersection.

Critically examine the role of the organization in perception Q8 1.2

The Law of Closure:
We have a tendency to perceive stimuli as complete and balanced even when pieces are missing. Closure makes us see incomplete figures as complete and supplies the missing edge. beyond gaps and barriers. In other words, within limits, physically incomplete figures tend to be perceived as complete figures or as meaningful wholes.
Critically examine the role of the organization in perception Q8 1.3

Here, grouping occurs in a way that favors the perception of the more enclosed or complete figure. Now from the figure above (See Fig. -5.5), the following curved line is not perceived as a curved line; rather, it is perceived as a circle. Here the curved line is not perfectly closed, but we see a circle because it is more tempting to perceive a complete figure than simply a curved line.

Attention and Perception:
The process of selecting a stimulus or a group of stimuli from among a large pool of stimuli is called attention. Attention is a complex process, combining a state of focused awareness with a readiness to respond. Attention influences both the stimuli an individual processes and the responses one is likely to make. Perception is a cognitive mechanism of sorting out, interpreting, analyzing, and integrating stimuli involving our sense organs and brain.

Perception is a receptive, selective, symbolic, and affective process. The process by which we structure the input and create perceptual coherence is called perceptual organization. Perception of an object or event is something more than the sum total of its sensory input. The perceptual organization puts sensory information together to give us the perception of coherence.

The Law of Common Fate:
According to this Gestalt principle, elements that are more in the same direction are perceived as together. Of course, this is a type of grouping on the basis of similarity but applied to moving objects. When we see a flock of birds moving in the same direction in the sky, it appears as groups or units. Now you can see how the law of common fate operates in the perceptual organization from the figure above (Fig -5.6).

Critically examine the role of the organization in perception Q8 1.4

 

The Law of pragnaz (Meaningfulness):
The principles of Gestalt grouping operate only when two or more elements, are simultaneously present in a visual field. According to Gestalists, the whole stimulus pattern somehow determines the organization of its own parts. In other words, the whole percept is different from the mere collection of its parts. Gestalt psychologists believe that all of these grouping laws are particular examples of a single general principle the Law of Pragnaz (Meaningfulness).

This principle reveals that the simplest organization requiring the least cognitive effort will always emerge. This law also proposes that we perceive the simplest organization which fits the stimulus pattern. The law of pragnaz is otherwise known as “the minimum principle of perception. ”

Critically examine the role of the organization in perception Q8 1.5

Again always we have a tendency to perceive figures as good, regular, and simple, with minimal cognitive effort. Therefore, this law is also known as the Law of Good Figure This law also emphasizes on the fact that we like to see regular and simple forms, rather than irregular forms.

Question 9.
Define the figure – Ground Relationship.
Answer:
Figure – Ground Relationship:
We tend to divide the world around us into two parts – a figure, which has a definite shape, and a location space, and ground, which has no shape, but seems to continue behind the figure and has no definite location. The figure-ground relationship helps clarify the distinction between sensation and perception.

Define the figure - Ground Relationship Q9

A figure is an object-like region in the forefront and the ground is the backdrop against which the figures stand out. The tendency to perceive a figure as being in front of the ground is very strong. When you perceive a region as a figure, boundaries between light and dark are interpreted as edges or contours belonging to the figure and the ground seems to extend and continue behind these edges.

When we see birds flying in the sky, birds are figures in the background of the sky. When you see the moon in the sky, the moon is the figure and the sky is the background. Similarly, the boat is the figure in the sea.

Define the figure - Ground Relationship Q9 1.1

The following difference in the characteristics of figure and ground relating to any perceptual activity was observed by a Danish Psychologist Rubin( 1958). The figure has a definite shape, whereas the ground appears to have no shape. The figures have the quality of a thing, but the ground appears relatively formless.

The ground seems to continue behind the figure. But the figure seems to be present in front of the ground. The figure seems to be closer to the perceiver with a clear location in space. But the ground is farther away. It has no clear location in space. Always figure appears more impressive, dominant, and better structured. A figure has more associations with meaningful shapes than the ground.

Besides all these above differences, Coren (1969) revealed another difference between figure and ground. According to his observations, the figure is always brighter than the ground. There should be a stable perception of the figure. In short, a figure should be perceived as a figure on different occasions.

But when the figure-ground relationship is ambiguous or is possible for different types of interpretation, the perception tends to become unstable. In these occasions, the figure and ground reverse their positions frequently. Very often, the figure becomes the ground and the ground becomes like a figure simultaneously. Almost spontaneously these reversals occur. Now, look at figure 5.8(a). What do you perceive? A vase or two faces?

Define the figure - Ground Relationship Q9 1.2

Perception of Movement:
Every day, we see the movement of different types of vehicles on the road, and birds and airplanes fly in the sky also, we see the movement of people around us. But how do we perceive this movement? Is there any difference between the perception of movement and the perception of static objects? In some instances, the objects do not move, but we perceive the movements of objects. How does this happen? Psychological, as well as physiological processes, are involved in the perception of movement.

Long Type Questions With Answers

Question 1.
What are the aims and objectives of teaching general science?
Answer:
Science has occupied a valid place in the school curriculum. Education of science which emphasized physical law and properties of matter and the application of scientific principles met in our daily life is an essential supplementary to general education. Science should be taught not with a view to making each pupil a future specialist but make him a useful citizen.

Thus, the school science course should form part of a sound general education. It should train the mind of students to reason about things he has observed and develop their power of weighing and interpreting evidence. It should also make him acquainted with the broad outlines of great scientific principles with the ways these are exemplified in familiar phenomenons and with their application to the service of man.

The objectives of science teaching may be classified into some categories. The first aim of science teaching is that students shall demonstrate a knowledge of the fundamental of science that may be brought into use in daily life. The knowledge will bring positive change in students, behavior. The second objective of science is that students should demonstrate abilities that are the by-product of knowledge.

These abilities will be exhibited in their behavior scientifically. The third most important aim of science teaching in high school is to make the students into more citizens and better equipped to improve community life. In order to achieve this aim, the course content in science should have practical applications to daily life. The fourth aim of science teaching is that the students shall demonstrate knowledge of the contributions made by our Indian scientists, in the science world.

The science teacher must stress their achievement science in class to that students must develop pride in their scientifically rich heritage. Thus, the science program should be aimed at causing the level of scientific knowledge, skill, and attitudes of the students to make them more productive in their home environment.

The other objectives of science learning are as follows:
Knowledge:
This means pupils should acquire knowledge of scientific terms and concepts, natural phenomena, modem inventions of science animal life and plant life human-machine and functioning, and so on. The knowledge is realized if the pupils recall and recognize scientific terms, facts, concepts, and symbols.

Understanding:
This means the pupils can explain and discriminate between facts, concepts, and data, illustrate specific terms, and concepts phenomena, locate errors in faulty statements, and so on.

Application:
Having realized this aim a pupil can give reasons for scientific conclusions, analyze the given data, formulate and test hypotheses, and predict new happenings and soon.

Skills:
Having realized this aim the pupils are expected to develop three types of skills.

  • drawing skills
  • manipulative skills
  • observational and recording skills.

Interest:
It creates interest to read scientific literature, collect specimens, take scientific hobbies, visit places of scientific interest, and participate in science clubs and science fairs.

Ability:
This activity of the pupil’s ability to use scientific terminology, improvise and manipulate the scientific instruments, collect suitable data from relevant sources, interest in the given data, and so on.

Attitude:
Having developed a scientific attitude the pupils will become free from bias and prejudices and they will become honest and truthful in recording and collecting scientific data.

Appreciation:
This means the pupils will be able to realize the importance of science in human progress appreciation. The contribution made by scientists to human progress and appreciation of the history of scientific development through the ages.

Utilization of leisure:
Having developed manipulative skills the pupils will be able to engage themselves in useful leisure time activities as making things of daily use such as ink, soap, candles, cosmetics, boots Polish, etc.

Vocational opportunities:

Question 2.
Write a note on the use of lecture methods in the teaching of science in schools. Give its merits and limitations?
Answer:
The lecture method involves teaching by means of spoken word, a format talk by the teacher. The method may profitably be used at a higher level and also at a lower level and its success will depend on individual teachers. This method is also known as the storytelling or conversational method. The teacher is well prepared and will present lectures that will stimulate better learning. In the lecture method, the lecture is taken as a technique of description, explanation, and clarification. This method is useful and effective with young and college students.

Merits:
The lecture method has the following merits:
It develops the power of concentration in the students, and also their power of experience, expression, thinking, and reasoning. economical and time-saving. It keeps both the teacher as well as the students active. Through this method, it is possible to establish direct contact knowledge between the teacher and the taught. Through this method, it is possible to elucidate difficult and complicated thoughts and ideas. This method is very useful in introducing a lesson. It also threw light on the practical aspects of education.

Demerits of lecture method:
The method kills the liveliness of the class. It is the teacher who reigns supreme and the students remain passive partners. This method is not useful for the students of the lower class In this method it is the teacher who remains active and the students remain passive. This method is not psychological and scientific. The knowledge that is required through ‘this method is neither complete nor perfect nor stable.

Through this method it. is not possible to provide practical education to the students because there is little creativity or activity in this method. This method has very little scope for evaluation and examination of the students by the teacher while he is teaching them. It strikes a severe blow to the originality of the students. Their curiosity remains unsatisfied and the thirst for knowledge continues:

Question 3.
What are the main features of the demonstration cum discussion method in teaching science? What are the advantages and disadvantages?
Answer:
The main features of the demonstration and discussion method are as follows:
Demonstration-cum-discussion method is not a single method. It is a combination of two methods, more clearly a result and method resulting from the combination of discussion method as well as demonstration method. This method involves the active participation of the teacher and students at the same time which is unlikely in other methods say, the lecture method. The teacher is in active the laboratory work and heuristic methods are active and so on.

Demonstration-cum-discussion method through group participation develops keen observation power and scientific reasoning in students which is. not possible either ill the lecture method or in the Heuristic method. Demonstration-cum-discussion method ‘ of teaching science encourages a maximum amount of participation among students than other methods.

The demonstration-cum-discussion method through group participation develops keen observation power and scientific reasoning in students which is hot possible either in the lecture method or in the Heuristic method. Demonstration-cum-discussion method is the only method in which the interest of the students is measured. Through this method force, and discipline is maintained. This method develops skills in handling apparatus, free-thinking, and cooperative spirit among students.

Disadvantages:
If deconstruction-cum-discussion method is not properly used then all students get a chance to take part neither in a discussion nor in experimentation: Thus, the principle of learning by doing is not aided by the method. The student’s donor gets the direct experience of doing experiments. So their skill in apparatus handling is not properly developed. If the teacher does not take care of students to become undisciplined. through this method.

CHSE Odisha Class 11 Foundations of Education Unit 4 Method of Teaching General Science Questions and Answers

Question 4.
What do you mean by laboratory method in teaching science? How can you make use of this method? What are the merits and demerits?
Answer:
The laboratory method is one of the best methods of teaching science. In this method teaching the subject is done in a laboratory. The students are given an opportunity to carry out experiments independently. The teacher observes their activities. He asks them to write out their observations. Theoretical studies get verified through laboratory work and thus learning experiences are gained.

In the laboratory method, the student performs a particular work of the experiment. He learns to follow directions, conduct experiments are record observations to find out results. While the student performs experiments, the Demonstration-cum-discussion method develops skills in scientific thinking. These are some of the main features of demonstration-cum-discussion method.

Advantages:
This method is economic from the point of view of money and time. The method obeys the rule of learning by doing what the students do or see they learn. So this method is very much psychological. It is useful when the apparatus required for practical work is costly. There the teacher can improvise the apparatus and demonstrate it.

If the teacher wants to revise some of the principles of science subject, he can do it by demonstration-cum-discussion method. the teacher is free to help students to perform experiments. The teacher is free to help the students having difficulties in their work. The teacher acts as a friend, philosopher, and guide in laboratory work.

How to use it effectively:
Laboratory methods should be used when a class can be divided into small groups. A good laboratory method is guided by a heuristic approach; The teacher should take the help of students in showing up for laboratory demonstrations. The students should be trained in the art of observing and recording reporting. The reporting of the laboratory, work includes areas like a statement of the problem procedures used observations made and conclusions drawn, etc.

Advantages:
It is based on the principle of learning by doing. It is interesting and joyful for students. It develops skill and efficiency as the students do experiments by themselves. An activity when performed is remembered for a longer time. Team teaching can be possible with this method.

Limitations:
It is not economical. It requires resources like a laboratory, equipment, furniture, etc. which, can not be made available in each school. It requires a small teacher-pupil ratio. It has been criticized as wasteful because of students in the high school stage. Sometimes this method does not develop the heuristic talents of students.

Question 5.
What are the main features of the problem-solving method? Discuss the merits and demerits of this method?
Answer:
Problem-solving approach presupposes the existence of a problem in the teaching-learning situation. A problem is a difficulty or obstruction which has to be overcome to reach, the goal. A human child has to meet and solve problems as he grows older and older. the problem-solving method aims at presenting the knowledge to be learned in the form of a problem. It begins with a problematic situation and consists of continuous, meaningful, and well-integrated activity. The problems are set to the students in a natural way and it is ensured that the students are genuinely interested to solve them.

Main features of the problem-solving approach:
It is a research-like method lt involves scientific thinking as a process of learning the essential features are as follows Formulation and appreciation of a problem or the emergence of a problem or selection of a problem. Collection of data or information to solve the problem. Analysis of the data. Formulation of hypothesis Conclusion. Applying the idea to a new situation.

The problem:
The problem arises out of the felt needs of the students. The problem must be familiar to the students. Before setting the problem the teacher should look at the following things. The problem should be suitable to the maturity level of the students. The problem should be easily solved. The problem should be worthwhile for the reader.

Collection of data:
After formulation of a problem, the teacher should stimulate the students to collect data in a systematic manner from various sources like textbooks reference books, magazines, newspapers, and from other sources like observation, discussion, and interviews,s, etc.

Formulation of Hypothesis:
At this stage, the students should look to the following regarding the solution to the problem. Selecting important factors related to the problems. Identifying the different relationships which may exist between the factors. Analyzing, selecting, and interpreting the relevant data. Judging the significance of data.

Testing of Hypothesis :
Checking the hypothesis which recognizes authorities Division experimental procedures suitable for testing hypothesis. Organizing data. Applying the hypothesis to the problem to determine adequacy.

Analysis of evidence and drawing inferences:
Children should be taught to the scientific and reasonable in interpreting the data. It is essential to break the large area into different segments and then to consider ways and means for analysis; the analysis of data should be accurate and to the point.

Drawing Conclusions :
The conclusion should be drawn by the pupils themselves and the teacher is to see how far it is significant relating to the solution to the problem.

Analysis of the data in a new situation:
The students should be able to recognize the common and identical elements in the principle of the problem and apply them in the new life situation.

Advantages:
From the standpoint of learning principle of problem-solving is very valuable since they are the result of the cumulative and generalized experience that makes up the basis of knowledge and understanding. It is much easier for members than the facts through the method. It develops reflective thinking. So. it stimulates thinking, reasoning, and critical judgment in the students.

It develops qualities of dependence on the students as they are to face the problematic situation themselves. It is a stimulating method. It acts as a great motivating force and directs students, attention, and activity. It serves individual differences. It develops desirable study habits in the students. They get engaged in the analysis of the problem, reflective thinking, and systematic.

data gathering, verification, and critical study. It is a method of experience-based learning. Problem-solving is done by self-experience. There is the possibility of close contact between the teacher and taught. The students get valuable social experiences like patience, cooperation, self-confidence, etc.

Disadvantages :
It is a time-consuming method. The progress of students is very slow. It is difficult to organize the contents according to the needs. All topics cannot-be-taught by this method. All require adequate resources. The method does not suit the students of lower classes. They do not possess enough background for a scientific approach to problems.

The project method is a pupil-centered method carried out in school or outside the school. The essence of this method is to carry out a useful task on a ground in which all the students work co-operatively learning by doing and learning by the living are the two cardinal principles of this method. Children learn through association, cooperation, and activity.

The various steps of the method are as follows:

  • Providing a situation
  • Choosing and purposing
  • Planning
  • Executing
  • Evaluation
  • Recording

Providing a situation:
The teacher should provide such a situation to the students which may create some problems for them and in which they feel interested to work.

Choosing and purposing :
The children should be tempted to choose a project. The teacher should stimulate discussion through suggestions. The project chosen should be to the need of the pupils. The purpose of the. project be clearly defined and well understood by the pupils.

Planning:
The success of a project depends upon a good planning. The students should plan out the whole scheme under the guidance of the teacher. The teacher should prepare two to three plans in his mind and guide the students Every child should be encouraged to participate in the discussion and to make suggestions. All the students are taught to write the plan properly.

Executing:
The teacher should assign duties and distribute work among the pupils of a group to their interests and abilities. Every child should contribute actively towards the execution of the project. The teacher should guide them.

Evaluating:
The students review the project and find out the mistakes if any. self-criticism is an important training and should not be neglected. The teacher should see that the objective of the project has been achieved.

Recording :
The students should keep a complete record of work, how they planned, what discussions were held, how, duties were managed, etc. and finally criticism of their own work.

Merits of the project method:
The project method is based on the laws of learning, the law of readiness, law of exercise, and the law of effect. It promotes cooperative activity and group interaction.

Question 2.
How History is related to other schools/subjects. Discuss, in brief?
Answer:
History is a subject that is related to almost all other subjects, In this connection history is not a subject at all but a house in which all subjects dwell. Here we will discuss the relationship of history with some other important school subjects:

History and literature:
Every branch of literature is the product of historical situations. History is the record of man’s deeds whereas literature is the product of historical situations. Literature is the record of man’s feelings, emotions, and imagination. Historical facts need languages for their expression. Many literary works provide a lot of historical facts. So history is related to literature.

History and Geography:
History, Geography, and Civics are included in social science. History stresses time whereas geography stresses space. Sometimes geography offers an explanation for people or countries that would be complete without some reference to the geographical account of that place.

History and Political Science:
Political science and history are closely related. Political science as a subject deals With the branch of historical studies which mainly gives an account of the growth and development of the administrative setup of different countries. Political science is the science of citizenship and such citizenship refers to good knowledge of history. History gives information about revolutions and political movements which helps political scientists in their study. History without the proper analysis of political events of the time is nothing but simple fiction.

History and Economics:
History describes the story of a man of different ages, which also includes the economic conditions of the people; Analysis of the growth of economic institutions is an important part of history. The history of past economic events throws an important light on the present economic policies and helps the formulation and verification of different economic laws and theories.

History and Science:
History is man’s story on earth. This includes the long chain of discoveries, explorations, and inventions that man has achieved through the ages. Science has its own history. Subjects like Anthropology include both history and science. Besides, those subjects of history is also related to music art, handy work, etc. which are taught in the class.

Question 3.
Write a note on the story-telling method in teaching history?
Answer:
Children arc wry fond of learning stories. That’s why the storytelling method has taken a special place in teaching history. Children derive pleasure in listening story and history taught in storytelling to become effective and easily understood the subject matter. It is suggested that for the age group of 8 to 10 history should mainly be carefully chosen graded series of written with attractive descriptive details.

This would arouse the interest of pupils and provide scope for imaginative understanding and enjoyment. For primary classes in teaching history, the teacher follows that method. He uses necessary aids to make teaching effective so the children feel easy to understand the subject matter and keep the man’s memory easily.

Advantages:
The storytelling method has become effective and fruitful in learning for lower-grade children. While telling the story the teacher makes movements of his body and followed them with actions. It has certain advantages. Enhancement of interest Storytelling can give life to the dead facts. It is a more effective way of bringing out all the aspects- cultural, economic, and social of this ancient society. Development of imagination Stories develops the imagination of people.

They take the pupils far away from this material world and offer ample scope for the play of their imagination. The teaching of creative faculties Stories in historical happenings and materials provide any scope for the children to utilize their creative ability in various ways. Inculcation of virtues The teacher through storytelling can include in the children virtues like pity, truthfulness, charity, etc.

Selection of stories:
The following principles should be taken into consideration for selecting stories. The story should be fully known to the teacher himself. The story should be selected to suit the mental age of the pupils. The teacher may take the stories from any source he thinks suitable, local or world history, cave life, hunting life, etc. but must take the necessary continuity into consideration.  The story should be full of action and details.

role of the teacher:
Storytelling is an art and the story teacher should know this art, the teacher should possess the ability such as historical personages when he narrates stories. He should be equipped with a rich imagination. power, accurate, varied, and wide knowledge of the past.

Question 4.
What is narration-cum-discussion method? Discuss the advantages of teaching history in the classroom?
Answer:
Narration-cum-discussion method is useful both for juniors and seniors. In this method, there is scope for both teachers and pupils for exchanges their opinions. Method, while presenting the subject matter the teachers ask for some anticipation and discussion with the students. Teachers put these questions in such a manner that their answers lead to the development of both discussion and narration methods.

When the teacher was narrating the subject matter, he takes the help of different audio-visual aids for making the teaching attractive and effective in die formation to the students about different events and trends. In order to motivate the pupils to study a new topic the teacher takes the help of narration, a technique for presenting the topic while narrating the teacher can indicate by modulating his voice through gestures and facial expressions, the exact meaning that he wants to convey to the pupils.

In order to aid the memories of children in the primary levels narration work is desirable to give through black-board summary. The children should be asked to take down the blackboard summary in the notebooks Advantages of the method. The method develops the imagination and insight of the pupils. It enables them to apply their learning in new situations. In this method, students do not become passive listeners. They take an active part in discussion and narration.

So the teaching becomes lively and effective. This method clarifies all doubts of the students. He gets a chance to discover what he did not know and what he has overlooked. Genuine potential students are judged by the teacher in this method. The method activates the learners of self-evaluation. It is also helpful in establishing an attitude of looking forward to progress and growth.

Question 5.
How the demonstration method is employed in teaching history. Explain?
Answer:
The demonstration is an important method for making the teaching of history interesting, effective, real, and lively. All children are acting and dramatic instinct young children, often do something quite spontaneously in imitation of others’ actions. By the technique, the natural tendency of the young mind is harassed from the educational end.

Thus historical dramatization is an attempt at presenting historical events with the help of the students. Hence, through role-playing, the students develop insight into the historical scene and actions. On the other hand history a subject for study offers great scope dramatization. So the history teacher should fully utilize this method for making the study of history interesting and real.

The technique of demonstration:
Demonstration of historical events can be of two kinds such as extempore dramatization and prepared dramatization.
Extempore dramatisation:
In this type of dramatization, the whole lesson may be presented in a dramatic fashion. It does not require any previous preparation fashion. It does not require any previous preparation on the part of the students no customer or stage effects are required. The presentation can be done in different ways.

The teacher himself may present the whole lesson in a dramatic style. The teacher may ask a few selected students to come to the front and act out the dialogues and monologues in a dramatic fashion. The teacher may write out home what has to be read by the students in the class.

Prepared dramatization:
In this kind of dramatization, preparation is made in advance. Students are taught to speak out dialogues and act accordingly. When the scene and action have been selected the teacher must help each with the appreciation of his part by rapidly reviewing the main points of the story.

Advantages of this method:
In the dramatization method, the students learn by doing. So their experiences are strengthened through mental and physical activity. It provides them an opportunity to acquire knowledge of historical happening through activity. It helps the students to develop their power of thinking and reasoning. It presents the historical event with human feelings and ideas.

The students find themselves involved in the activities of the past. It thus enables them to understand the persons and events in a historical perceptive. The device makes history teaching real. It makes the dead positive, interesting, and enjoyable for the students. The method helps the students to develop the art of speaking and self-confidence.

Question 6.
Discuss the project method in teaching History. Give its advantages?
Answer:
According to Kilpatrick “A project is a wholehearted purposeful activity proceeding in a social environment. A project is a unity of activity in which pupils are made responsible, for planning and purposing. So educational projects must be purposeful, life-oriented, and society-based activities that may be problematic and realistic.

Characteristics of project method:
Life oriented:
The project method aims at preparing students for life. It is related to day, today life and its problems. So the method is life centred.

Self-expressive:
A project seeks to bring out what is in the child and develop his innate potential. It gives an opportunity for self-expression and the school environment provides adequate scope for self-development.

Activity-based:
The project is implemented through activities, It is a method of working out the practical Solution to the problem.

Motor Activity in Nature:
A project must use manual or motor activities. The activities need skills and technical knowledge. The activities not only help in executing the project but also develop the personality of the children.

Play way Activities:
Children when engaged in physical activities get immense joy and contribute the most towards productivity. Any kind of imposed activities is uninteresting. In play way activities the monotony is removed and joy is enhanced.

Types of Educational Projects:
Produce type:
Projects when are related to production. Construction of a house, a road, a, garden or a factory, a picnic, or staging a drama are called consumer type of projects.

Problem type:
Projects which are related to a particular burning problem of the life or society are called problem types. Students take up projects to bring peace and harmony among the people.

Advantages of the project method:
Emphasis on:
Freedom The project method encourages adequate freedom essential for school life, and for the effective teaching-learning process. It gives self-direction, leading to successful learning experiences. Students develop creativity and productivity attitudes.

Learning through problem-solving:
In the project, method emphasis is given on practical life situations and their problems and students are unexposed to day, today life with adequate preparedness knowledge, interests, and attitude for learning from their experiences.

Training in citizenship:
Projects are planned and implemented dramatically. The project, method encourages students to cooperate, think, and act together for achieving common objectives. It provides them with training and democratic living sharing responsibility giving leadership, showing respect to individuals, and exercising citizens’ rights and duties properly. Such a program school may work as a kind of preliminary training for citizenship.

Psychological sound:
Organization of a project in school to the natural needs- and conditions promote learning outcomes. This is psychologically sound. The three important laws of learning the law of readiness, the law of exercise, and the law of effect are very well taken care of. In the implementation of the project, students get joy and motivation towards learning.

Social values emphasized:
The school as a society the project work develops social skills, social efficiency, and social cohesion. Through the organization of educational projects students jointly plan and execute the project and less front of each other at various phases of implementing a project.

Question 7.
Discuss the dramatization method in Teaching History?
Answer:
It is a common experience that history does not only deal with material objects but also with events, human ideas, and sentiments happening in time, which have been preserved through verbal symbols. It is impossible to transfer them into audio-visual symbols through models and even through puppets Moreover, historical happenings are not isolated events, but are sequences of happenings one having a connection with the other.

These concepts of casual sequences and movement cannot be represented by models of any kind. Hence, dramatization seems to be the most powerful audio-visual aid in history teaching. In dramatization, an individual acts as somebody had acted in the past. As a result of which the events become quite natural and lively.

In history demonstration means the reconstructing of an experience in the past that is of historical significance, It is the attempt to transcend the barrier of time and place and relieve the experience concerned. A child dramatizing a character has to feel like the character and to a degree must become the character. There is a better way at making historical experience real than through dramatization.

This is the only way of learning by doing in history. The pupils assimilate the essential facts of history by playing the different historical events in the connection. Those who do not directly participate in dramatization but witness it, also get in the way of the character. Their experience becomes almost as real to them as the action.

Kinds of dramatization:
Dramatization is of many kinds. They are as follows:
Full-length play:
It is a vivid, realistic, and full representation of the whole scheme, an idea emotion, a happening, or a situation. It takes hours in performance, and success in it requires one to come up almost to professional standards. Any way it requires detailed preparation and educational implication should be subservient to its beauty as a drama.

Class:
dramatization The teacher may undertake still more informal dramatization within the history class itself. It may not occupy the whole period and may be made to illuminate part of the lesson. To give the teacher a concrete idea of how this class dramatization could be done about half a dozen examples of each type from Indian history are given below. An attempt has been made to Include as many varieties as possible in the selection of topics for dramatization.

The pageant:
A pageant is an attempt to depict an idea or a feeling by arranging a spectacle. The appeal is solely visual, presenting a long and complicated event very effectively within a short compass forcing attention on key points.

Tableau:
Tableau is a picture like some composed of human characters against a background there may be a basic expression but no speaking.

Shadow play:
It is another technique for dramatization. In this technique, there is a thin screen between the actors and the audience.

Puppet shows:
Puppet enjoys a distinguished position as a dramatic art. There are many kinds of puppets.

Question 8.
Describe the different steps of the history lesson plan for class (VIII)?
Answer:
Like all other subjects, a history lesson plan has three steps:

  • Introduction
  • Presentation
  • Evaluation Application

Before starting the introduction it is essential to mention general as well as specific objects, materials or instructional aids to be used and previous knowledge of pupils assumed by the teacher.

Introduction:
The teacher has to introduce the topic in the class. The introduction serves two main purposes. To enable the teacher to know the background knowledge of pupils and to arouse an interest in the children to learn the topic. A topic can be introduced in many ways. The teacher can ask, recite some, or the like to introduce a topic. At the end of the introduction step, the teacher announces the topic of the class.

Presentation:
It is the most important step in teaching history. The new knowledge is presented in the step. In the storytelling method, the teacher tells the story and asks a few thought-provoking questions in the middle of the story. In the narration method, the teacher goes on narrating appropriate points and asks some thought-provoking and anticipation questions to the students. During the narration, the teacher makes use of various teacher skills like narration, questioning, and using audiovisual aids.

using blackboard and the like Thought Provoking Questions:
Few thought-provoking or anticipatory questions are asked during narration. These questions are asked during narration. These questions are put usually when the teacher feels that pupils can anticipate the effect of a cause. These questions are generally indirect involving the insight and foresight of the pupils.

Comprehension questions:
A sufficient number of comprehensive questions are asked after the narration is over. These are small and direct questions. These questions are asked to, know the extent to which pupils comprehend the topic.

Summary Questions:
A few summary-type questions are asked at the end of the presentation step in step to draw the summary of the topic.

Evaluation:
In a third of the plan, a few objectives based objective type questions are asked to evaluate the extent to which the specific objectives of the lesson have been achieved.

Long Questions With Answers

Question 1.
What is Neuron? Describe the structures and functions of neurons, flow does it differ from a cell?
Answer :
Building Blocks of the Nervous System:
Neurons are basic units of the nervous system. These are the nerve cells that actually process information. The human brain contains about 100 billion neurons. The average neuron is as complex as a small computer and has as many as 10,000 physical connections with other cells. Most neurons are created very early in life, but their shape, size, and connections can change throughout the lifespan. On the whole, the way the neurons function reflect the major characteristics of the nervous system.

Basic Structure of a Neuron:
Not all neurons are alike. They are specialized to handle different information processing functions. However, all neurons have some common characteristics. In general, every neuron has the following structures

  • Cell body or soma
  • Dendrites
  • Axon and
  • Terminal buttons or axon terminals
    (See fig. 4.1)

What is Neuron Q1

Cell body or Soma:
The cell body or ‘ Soma’ is the enlarged head of the neuron. It is enclosed by the cell membrane. The cell body contains the nucleus of the cell and cytoplasm which sustains its life. Some are the head side of the neuron. It uses oxygen and nutrients to generate energy. Its shape varies depending on the type of neuron. Generally, neurons transmit information in only one direction, that is, from the dendrites through soma to the axon to the terminal buttons.

Dendrites:
Dendrite is the branching fiber from the cell body. A neuron receives information at one end and sends out messages through the other. The part of the cell which receives incoming signals is called a dendrite. The dendrites receive nerve impulses from adjacent neurons or directly from sense receptors and conduct them to the cell body.

Axons relay or send impulses from the cell body to other neurons or to muscle tissue. The very word ‘dendrite’ came from the Greek word ‘dendron’ which means ‘tree’. So dendrites of a neuron look very much like trees. Dendrites are extended from the cell body. Dendrites increase the neuron’s surface area, allowing each neuron to receive input from many other neurons.

Axons:
Two types of extensions are found in the cell body. The short extensions from the cell body are called dendrites. But the longer single-branched extensions are called the axon. It is that part of the neuron which carries information away from the cell body to other cells. Each neuron has only one axon.

The point in the axon nearest to the cell body is called the axon hillock. Axons may have some branches which are called axon collaterals. Axons have two coverings. Of course, these two coverings are not found in every neuron. The outer boundary of the neuron is called the membrane. The membrane serves as a barrier for the neuron.

In some axons, there is a fatty white sheath called the myelin sheath. Axons having myelin sheath are called myelinated axons and which do not have it is called unmyelinated axons. Axons without myelin sheaths are not very good conductors of electricity. With the insulation of myelin sheaths, axons transmit electrical impulses and convey information much more rapidly.

Another covering is found in axons of neurons exclusively outside the brain and spinal cord. It is called a neurilemma. Neurilemma is a very thin covering that takes part in regeneration. If a neuron outside the brain and spinal cord is damaged, it can be regenerated. But the neurons of the brain and spinal cord can not be regenerated, as they do riot have neurilemma in their actions. Once these highly specialized cells are damaged, they are damaged forever.

Terminal Buttons:
An axon conducts information along its length which can be several feet in the spinal cord and less than a millimeter in the brain. At the far end of the axon, some swollen and bulb-like structures are there which are called terminal buttons. Through these buttons, stimulation passes to Astrocytes and oligodendroglia are two important glial cells.

Astrocytes produce chemicals that neurons need to fulfill their functions. On the other hand, astrocytes help control the chemical composition of the fluid surrounding neurons. The main function of oligodendroglia is to provide support to axons to produce myelin sheaths.

Functions neurons:
The main function of the neuron is to communicate messages of stimulation in the form of nerve impulses. Our behavior is only possible through the flow of nerve impulses. Near about 10 billion neurons fire in our brain. They send and receive various nerve impulses. This is the communicative function of the neuron.

Sensory or afferent neurons come from receptors and go to the brain and motor (efferent) neurons go to muscles or glands. The inter-neurons are the linking neurons. An electrochemical reaction occurs inside when a neuron is adequately stimulated. Neurons fire or do not file like a gun. There is no in-between stage. This is called the all-or-none principle.

All neurons follow this principle. They are either off or on. Now let us see how neurons serve their communicative functions and how nerve impulses or nerve energies are formed. The neuron contains intracellular fluid. The fluid on the outside of the neuron is called the extracellular fluid. In between these two types of fluids, there is a cell membrane.

The fluid contains many dissolved substances. Many chemical substances are broken into pieces when they dissolve in water or any fluid. Ions are electrically charged particles when dissolved. The electrical charges are negative or positive and are carried out by ions. As you know, positive and negative electrical charges attract each other.

But only positive electrical charges or negative electrical charges repel each other. Since ions are found in both extracellular fluid and intracellular fluid, the same thing happens in a neuron. (See fig. 4.3) A neuron works to maintain its resting potential. It does not come automatically.

When a neuron is in a resting state, there is a negative electrical charge of about – 70 million votes. Ameli volt one – thousand of a volt. This is called the resting potential of the neuron. The neuron can be best compared with a battery with the inside of the neuron representing the negative pole and the outside of the neuron representing the positive pole (Koester, 1991).

When a neuron is stimulated by externals like heat, light, or sound, the message arrives, and the positively charged ions outside the neuron rush inside the neuron at rates as high as 100 million ions per second. This sudden arrival of positive ions inside the neuron causes the charge to change from negative to positive.

When it reaches a critical level, an electrical nerve impulse known as action potential travels down the axon of the neuron. The very term ‘action potential’ is used to describe the brief wave of positive electrical charge which sweeps down the action.

What is Neuron Q1 1.1

Generally, an action potential lasts only about 1/1000th of a second. When a neuron sends an action potential, it is commonly said to be ‘ firing’. The action potential abides by the all-or-none principle. Once the electrical impulse reaches a certain intensity, it fires and moves all the way down the axon without losing any of its intensity.

Again, the axon potential moves from one end of the axon to the other. After the nerve impulse has traveled, the positive ions are pumped out of the state. It becomes ready to fire again. The flow of the nerve impulse depends upon the diameter of a particular neuron. A nerve impulse is carried out speedily through a larger diameter and slowly through a smaller diameter.

Absolute Refractory Period:
After the action potential is transmitted by the neuron, it takes rests for a brief period of time. The neuron can not be fired again immediately, no matter how much stimulation it receives. It is just like reloading the gun after each shot. This time span just after carrying action potential during which the neuron is inactive is called the absolute refractory period.

During this period, the neuron is in resting potential. This time span of resting time is usually less than 1/1000th of a second. An action potential can not be produced during the absolute refractory period. When this span is over, again the neuron can cany a nerve impulse. The absolute refractory period is followed by a relative refractory period during which a strong stimulus can make the neuron active.

Threshold Point:
Weak stimuli can not produce an action potential in a neuron. Therefore, a stimulus of a certain strength is needed to produce an action potential. So the point at which a stimulus triggers an action potential is called the threshold of a neuron. Different neurons have different thresholds of excitation. Generally, the threshold point of each neuron is fairly constant.

Cell:
The nervous system of a living organism is made up of cells. A cell may be defined as a unit of living material. All can live independently by synthesizing within themselves substances from the nutrition absorbed from their environment. A cell contains living material called PROTOPLASM which is surrounded by a membrane called plasma membrane or the cell membrane.

Question 2.
Define AH or None law. Neural transmission or synapse?
Answer:
AH or None Law:
According to this principle, the nerve fibers respond completely or not at all. The stimulus has to be a minimum strength for the nerve to react. A weak stimulus will excite a few nerve fibers and we may not have sensory experience at all. But a strong stimulus will excite a larger number of nerve fibers resulting in a more intense experience. We can take the lighting of a match stick for illustration.

We must strike it with a certain amount of force to ignite the powder. If greater power is striking is exerted, the match flame will not be brighter. Beyond the minimum pressure necessary, any extra effort does not add to the brightness of the flame. This is exactly what happens with the stimulation of a nerve fiber. When such an explosion takes place, the nerve fiber is ready for another charge in a fraction of a second.

This principle is called the ‘all-or-none law”. Further, the nerve impulse is an electrochemical stimulation, which does not decrease in its intensity as it travels through the axon. If an axon carries any nerve impulse at all, the impulse continues to maintain the same strength throughout its travel in the axon until it reaches the terminal buttons.

The speed of a nerve impulse depends on the diameter of the axons. The larger the diameter, the greater is the speed. The strength of the nerve impulse depends upon the nature of the axons. It must be remembered that the dendrites and the cell body of a neuron do not obey the all-or-none principle. Only this principle is applicable to axons. So the axon is only governed by this law.

Neural Transmission:
No doubt, our mental functions stem from biological functions. In turn, they also influence our biological activities. Neural activity is biological activity. Neural activity is the biological medium in which all our psychological processes occur. Therefore, it is necessary to gain preliminary knowledge about how neural impulses travel from one part of the biological system to another. Not only the neural impulse travels within a neuron, but it also travels from one neuron to the other. The two major parts of the neural transmission are

  • communication within a neuron (action potential) and
  • communication between neurons (synaptic transmission).

We have already discussed how neural impulses travel from one neuron to another neurons.
Synapse:
A synapse is a gap or junction which is generally found between the axon tip of one neuron and the dendrite of another. Neurons never touch each other. The nerve impulses are transmitted chemically across a small gap between the neurons. This type of contact provided between the axon of one neuron and the dendrites of another neuron is very interesting and significant.

The gap is very minute so that the conduction can easily go on. It is the synapse that makes our motor learning possible. When an impulse arrives at the end of an axon, electrical conduction in the axon is changed to chemical transmission. The tiny sacs in the terminal buttons of the axons, called synaptic vesicles release a transmitting substance called “neurotransmitters” which can the message to the other neuron.

Before the electrical impulse across the synaptic gap, it must be converted into a chemical signal As their name suggests, neurotransmitters transmit or carry information across the synaptic gap, it must be converted into a chemical signal. As their name suggests, neurotransmitters transmit or carry information across the synaptic gap to the next neuron.

When a nerve impulse reaches the end of the axon, it triggers the release of neurotransmitters which flood the synaptic gap. The dendrites of the receiving neuron come in direct contact with these neurotransmitters and receive the message. The receiving neuron will experience a change if the neurotransmitters are sufficiently stimulated, the received impulse will be conducted within the neuron and will be relayed from neuron to neuron until the message is completed.

It is estimated that the billions of neurons in the brain have trillions of synapses. There are many neurotransmitters. Each of them plays a specific role and functions in a specific pathway. Some neurotransmitters stimulate or excite, whereas, others inhibit neurons from firing (Bloom, Nelson & Lazerson, 2001). some neurotransmitters are both excitatory and inhibitory.

Most neurons secret only one type of neurotransmitter, but many different neurons are simultaneously secreting different neuro-transmitters into synaptic gaps of a single receiving neuron. Researchers have identified more than 50 neurotransmitters, each of which has a unique chemical makeup. Here, let us consider the functions of some neuro-transmitters which have major effects on our behavior.

Define AH or None law. Neural transmission or synapse Q2

Question 3.
Describe the structure and function of the spinal cord.
Answer:
Central Nervous System Structure and Function:
The central nervous system is well protected in the bony case of the skull and spinal column. It is divided into the spinal cord and the brain. The sensory or efferent neurons carry impulses from receptors into the central nervous system. The motor or efferent neurons cany impulses originating in the central system outward to effectors.

The Spinal Cord-Structure:
The spinal cord is a continuation of the brain below the medulla. It has a simple structure compared to the brain. It presents the same structure from angle to angle. A cross-section of the spinal cord at any level reveals the same uniform structure. The different parts of the spinal cord are connected to the brain.

The membranes cover the spinal cord and separate the fine neural tissues from the bony box of the central nervous system, lire outer, middle and inner membranes are called dura mater, arachnoid, and parameter respectively. The spinal cord has a rich acroterial blood supply. In a section of the spinal cord, we find grey matter in the central region and white matter in the peripheral region. The grey matter consists of millions of cell bodies of neurons.

The white matter consists of processes of neurons, that is, of axons and dendrites. In a six-foot man, the spinal cord is about the diameter of a little finger and 45 cm long. We do not find the spinal cord in most of the primitive forms of animal life. But when we go higher in the scale of evolution the nerve cells are found to be gradually combining into clusters and groups. These nerve clusters grow up the first step towards the evolution of the spinal cord and brain.

Describe the structure and function of the spinal cord Q3

Connected to the spinal cord are thirty-one pairs of peripheral spinal nerves. In each nerve thousands of individual axons are bundled together. Some of these have sensory and some motor function. The sensory branches of the spinal cord enter the cord at the back of the dorsal portion.

The sensory branches cany into the spinal cord impulse generating in the sensory receptors in the skin, joints muscles, and viscera. After synaptic connections in the cord, the sensory activity runs toward the brain. On the other hand, the motor branches of the spinal nerves leave the front or ventral part of the cord. They control the axons of nearby muscles and glands.

Functions of Spinal Cord:
Complete transaction of the spinal cord proves that the spinal cord has communicative and integrative functions. Observations of patients show that if the cut of the spinal cord is above the level of exit of the spinal nerves to the arm and legs, the outcome is quadriplegia. Similarly, if the cut is below the arm level, but above the leg level, the person suffers from paraplegia.

In both cases, there is no recovery. There is complete anesthesia and permanent paralysis of the parts of the body below the level of the cut. Why there is paralysis? Because the sensory stimulations cannot reach the brain. The motor impulses also cannot come out because of this cut in the spinal cord.

So though voluntary movements in the parts of the body before the cut are absent, reflex actions are not lost. The presence of Kneejerk refer and the reflex arising out of the pinching in such patients indicate the integrative capacity of the spinal cord and also its capacity to respond adequately to simple stimuli and by acting differently to different stimuli.

The last act shows a crude kind of decision-making. However, the capacity to perform these actions upon command is lost in paraplegics. The moderating influences of the higher center are also lost. In normal people, the reflexes are under some sort of descending inhibition from the brain. But in these types of patients, the reflexes are relatively larger and more sudden.

Describe the structure and function of the spinal cord Q3 1.1

CHSE Odisha Class 11 Psychology Unit 2 Perceptual Process Long Answer Questions Part-2

Question 4.
What do you mean by reflex action and define its type or characteristic?
Answer:
Reflex Action:
The reflex action is a very simple type of response that occurs automatically without our voluntary knowledge. According to Woodworth, “It is a direct muscular or glandular response to a sensory stimulus.” The examples of reflex actions are many. If someone puts his finger inside the mouth of a new baby, he starts sucking it. When a mosquito comes in front of someone’s eye, it is automatically closed as a protective measure.

Aeroflex action is very quick and rapid because it proceeds directly from the spinal cord. It does not go to the brain while in other activities the sensory stimulation is carried over to the brain through the spinal cord. The brain, in turn, sends out the message for making a particular response. That is why there is some delay in making these responses to activities other than reflex actions.

Types of Reflexes:
Basic reflexes, postural reflexes, segmental reflexes, inter-segmental reflexes, and spinal reflexes, come under different types of reflexes. There are also muscular reflexes such as knee jerks, the withdrawal of the hand, coughing, sneezing, swallowing, crying, and grasping reflexes. Glandular reflexes such as the flow of saliva, and the flow of tears are also notable.

Characteristics of Reflex Action:
The reflex actions are involuntary, unlearnt, and innate in nature like winking, knee erk, withdrawing leg from painful stimulation, sneezing, etc. The individual has no control over such reflexes. They occur very abruptly within a fraction of a second and also terminate very quickly. The involuntary or primary reflexes are purely universal.

The same type of avoidance of the pin pricking, grasping, winking and pupillary reflex is found in almost every person in the world. The reflexes are unlearnt behavior. Most of the behaviors of neonates are expressed in terms of reflexes. In babies, these reflexes are found in their original form.

As they grow up, the number of reflexes decrease and learned behavior increase. In other words, reflexes decrease with age. But there are certain reflexes that continue throughout life, like a knee-jerk, eye blink, etc. Finally, reflexes protect the individual from danger and help in maintaining the safety and welfare of the organism. Reflexes have, therefore, many positive values.

A reflex action is different from an ordinary action. In ordinary action, sensory stimulation in the form of electric waves is sent to the brain through the spinal cord. The brain then sends the message about the response to be made through the effectors. But in the case of reflex action, the message does not go to the brain. The spinal cord controls it. So the reflex action follows the spinal cord.

Reflex Arc:
The structure through which reflex action takes place is called the reflex arc. It involves the sensory nerve, spinal cord, and motor nerve. Take the example of withdrawing the foot when the pin is pricked. Sensory neurons cany impulses to the association.

Question 5.
How many lobes are there in the brain? Describe their location and function.
Answer:
Four lobes, in the brain and these, are:
Frontal lobe:
It is located in front of the nearly vertical fissure of Rolando and above the fissure of Sylvius. It contains three important areas of the brain: the motor area, the association area, and the speech area.

Motor Area:
At the farther end of the frontal lobe and adjacent to the central fissure, we have the motor area Which controls the voluntary movements of various parts of the body like the leg, arm, face, etc. It is technically known as the precentral area (Broadman’s area 4).

Promotor Area:
It is located in front of the precentral area. It also controls complex muscular movements of the body. Each hemisphere is connected to the opposite side of the body. The right limbs are paralyzed if the motor area of the left hemisphere is damaged or destructed and vice versa, complete destruction of the motor area of one of the hemispheres will produce paralysis of the muscles, on the opposite side of the body. The motor area has centers that control different parts of the body such as feet, hips, trunks, etc.

Association Area:
Just below the premotor area, there is an association area that deals with psychological processes like reasoning and memory. These areas are also responsible for giving a coherent form to various experiences of the organism. It is because of the association area, that man is different from animals. The essential function of these areas is to react to immediate sense impressions and symbols as well.

A small baby does not have the capacity to react to symbols. But with age, the power to react with symbols grows and these symbolic processes become a significant part of the association areas. Because of these areas, we are able to correlate all our present experiences with past experiences and make use of memory and thought processes.

ParietalLob:
The parietal lobe lies near the central fissure in the back half of the brain. It has the somesthetic area, which is the most important functional area. It lies adjacent to the central fissure itself. The parietal lobe is the seat of sensation. All the sensory impulses coming from the various parts of the body reach this area. So it is named a somesthetic or body sensitivity area.

Like the motor area, here we have separate centers for receiving the impulses from different parts of the body such as the arm, Teg, etc. All the bodily sensations are projected in this area. If this area is damaged person cannot discriminate between a piece of silk cloth and sandpaper. The sensation of wool, pinprick, mud, or clay is projected in the parietal lobe.

Temporal Lobe:
The major part lying below the lateral fissure is called the temporal lobe. The auditory area is located here. Electrical stimulation in this area leads to the sound of all sorts of noises heard by the subject. Damage to this area leads to deafness. The area for recognition of music is situated in this area If the recognition area of the temporal lobe is destroyed, the person loses the taste sensation. Connected with the temporal lobe is the gustatory area which lies directly below the temporal lobe.

The olfactory area also lies at one end of the temporal lobe. So it is undoubtedly the most important area of sensitivity. Thus, neurophysiology research indicates that this area is more vital than the frontal lobe and it has also been suggested that memory may ultimately be found to depend upon the temporal lobe. It plays a significant role in emotional behavior. So it has close functional contact with the interbrain.

Occipital Lobe:
The shape of the occipital lobe is triangular and it is located at the back portion of the brain. It is the seat of visual sensation. The most important functional area located in this lobe is the visual area. The retina, the crucial Organ of the eye is connected with it. Optic nerves1 coming down from the eye are extended to the occipital lobe. If one of the optic nerves is damaged, either of the eyes will lose the visual ability.

But if one part of the occipital lobe is destroyed, the person will not be able to sec half of the object. Several optic nerves going down from the retina go to different parts of the occipital lobe and we see the objects. The cerebrum and particularly, the cortex, contains the major centers of intelligence, cognitive process, sensational process, and all such creative higher mental processes.

Functions of the Brain:
Sensory Function:
Specialized sensory areas are located to the parietal, temporal, and occipital lobes and they are known as sensory projection areas because nerve impulses originating in receptors are as if it were projected upon them.

Somasthetic Activity:
A portion of the parietal lobe located just behind the fissure of Rolando serves as a terminal or projection area for impulses originating in the skin and in the Kinesthetic receptors. It is called somesthetic or body feeling area. When this area is stimulated electrically in human beings these are reports of temperature, touch, and movement experiences in the body.

But no pain sensation is experienced in the body. Medical reports indicate that even when tumors are operated on from various areas of the cortex, no pain is experienced. So it is concluded that pain sensitivity is mediated by the thalamus and not by the cortex.

Visual Sensitivity:
At the back of each cerebral hemisphere, in the front part of the occipital lobe lies an area called the striate area which is responsible for visual sensation. The visual area in the right cerebral hemisphere receives impulses from the right half of each eye and in the left cerebral hemisphere from the left half of each eye. If the visual cortex of the right hemisphere is damaged, the right parts of both eyes become blind.

Total blindness will be possible only when visual areas are destroyed in both hemispheres. Flashes of light, whirling colors, and similar such visual experiences thus warn the epileptic patient that he is going to be attacked by a fix. How is this possible? Frequent irritation of tissues in the visual cortex of the epileptic caused by tumors brings these visual signals.

Auditory Sensitivity:
The temporal lobe contains the auditory area. When the temporal lobe of epileptic patients is electrically stimulated or is cut, the patient hears buzzing, humming, and even musical sounds. Destruction of the auditory cortex in one hemisphere leads to minor defects in hearing. If, however, both the auditory areas are completely destroyed, the person becomes fully deaf.

This indicates that each car has representation in both hemispheres. Broca, a neurologist, found that when an area on the side of the left hemisphere was destroyed, the loss of speech occurred which is known as Broca’s speech area.

Motor Functions:
These areas of the brain are involved in controlling the movements of the body. The primary motor area, secondary motor area, and supplementary motor area. These areas of the brain are involved in the movement of the body, control of postures, and the tension of muscles. The secondary and supplementary areas do not send long axons to the spinal cord. They send sort axons into the nuclei in the interior of the cerebral hemispheres.

From it, in turn, other short axons go to nuclei in the brain stem, and a chain of such neurons leads down to the spinal cord. When stimulated electrically, part of the motor areas cause movements in the extremities. So when these areas are injured or damaged, the same parts are paralyzed. As already indicated, movements on the right side of the body originate from stimulation of the motor area of the left hemisphere and movement of the left side through stimulation of the right hemisphere.

Damage to the motor area on one side is followed by loss of voluntary movement on the other side of the body. Though voluntary movement stops in a corresponding limb, when a part of the motor area is damaged, the individual is able to move his limbs reflexly in response to strong stimuli because reflex arcs function at the lower level and are not controlled by the higher centers. The supplementary motor area is located in the longitudinal fissure.

These parts of the brain are involved in the control of postures, tensions, and body movement. These areas send short axons while long axons are sent by the premotor area. It is now suspected though not confirmed that these short axons play a major part in the control of movements like trembling and jerking etc. When the lower region is stimulated, the face may be twitched, the mouth may be opened and closed, and the like.

It was earlier believed that paralysis produced by cortical injuries was permanent and the patients never recovered. But experiments with monkeys and rats show that limbs that are paralyzed by the destruction of cells present is the motor cortex sometimes recover their functions, this brings the hope that if paralyzed human beings are given proper training, they might also start showing muscular movements. It has also been proved in some cases by messages etc.

Associative Functions:
The association areas of each side of the cerebral cortex are connected with each other, with sensory and motor areas, with the thalamus, and with similar areas on the opposite side. The chief function of the association area is to correlate and integrate the simpler functions of the sensory and motor areas since the sensory area act as gateways into the cortex and the motor areas act as exits.

Therefore, injuries to the cortex outside but near the visual areas do not cause blindness but destroy awareness of depth and recognition of visual objects. According to Munn, The cerebral cortex is a device not only for receiving sensory and initiating motor impulses but also through its association neurons for connecting, relating, and integrating functions.

These integrative functions of the cortex plus its susceptibility to modification during an organism’s life | time provide the foundation of such psychological processes as learning, recalling, past experiences and thinking”.

Question 6.
State the structure and function of the autonomic nervous system.
Answer:
Autonomic Nervous System:
The anatomical distinction between the central nervous system and the autonomic nervous system lies in that the nerve fibers of the A.N.S. have always a junction with another neuron outside the brain or spinal cord on the way to muscles or glands. But such outside synapses are not found for nerves running to the straight muscles, that is, the central nervous system. By and large.

The A.N.S. controls the internal environment of the O while the CNS controls the impulses from the sense organs, organizes them in the brain, and sends the motor impulses to the muscles. Why is it called A.N.S. ? Because many of the activities it controls are autonomous or self-regulating activities such as digestion and circulation which continue from life to death even when the person is asleep or unconscious. Its activity never stops in a living organism.

Division of Autonomic Nervous System

  • Sympathetic System
  • Parasympathetic System

Sympathetic System:
On either side of the spinal column, closely connected with it through the spinal nerves the chains of nerve fibers and masses of cell bodies from which fibers extend to various visual organs. These are called sympathetic chains. This sympathetic outflow takes place through the thoracic and lumber regions of the spinal cord. Due to this it is also sometimes called “The Thora Cicolumbar System”.

Structure:
The sympathetic nervous system consists of 22 sympathetic ganglia in a man:
arranged along the spinal cord. These fibers originate in the spinal cord and either end upon the sympathetic ganglion or they may extend to the other bundles of the ganglion chain. By this, they help in connecting the various sympathetic ganglia with each other or they may go to the distant parts of the body or end near the muscles or glands.

Besides, there are three important ganglia in the neck region which are known as superior, middle, and inferior ganglia. These cervical ganglia play a significant role in controlling the blood vessels of the heart and head, and dilator fibers of pupils. In general, they influence the blood supply of the brain.

Functions:
As the name suggests, the sympathetic nervous system sympathizes with the organism during an emergency situation or need by mobilizing all bodily energies effectively in the direction of facing an immediate need or emergency situation. When the man is asleep, he is at the lowest level of activity.

At this stage, the sympathetic system is at its minimum in its function. Suddenly, he is awakened by the loud noise “Fire, Fire”. Immediately his level of activation rises to the maximum through the activation of the sympathetic system. The sympathetic system puts itself into action to meet this emergency situation. The man gets up and runs with maximum speed to help himself or others out of the fire.

The sympathetic system constricts the visceral blood vessels and directs them to muscles and the brain increases the rate of the heartbeat so that more blood is pumped through to the heart, and helps the secretion of adrenalin which raises the level of blood sugar necessary for more energy, etc. There is also inhibition of intestinal and gastric activity, widening of the pupils.

State the structure and function of the autonomic nervous system Q6

Let us take the case of a person who is angry. During anger, the action of the sympathetic system includes dilating the pupil of the eye, lifting the lid and protecting the ball, speeding up the heart rate, and raising blood pressure. There is also the cessation of digestive movements, peristaltic contractions of the stomach, and of secretion of digestive juices.

The blood that normally goes to these organs is diverted to the muscles to enable the O to face the emergency situation. All these duplicate the energy of the person. In this manner, the sympathetic system makes the O ready to face the emergency situation by helping in organizing the bodily resources to meet the situation more effectively.

Parasympathetic System:
It is a division of the autonomic Nervous System concerned with projecting and conserving the body’s resources, preserving normal functions, and maintaining a calm emotional state. It has two divisions :

  • the cranial part
  • The sacral part.
    So it is called the craniosacral system. But here there is no such chain of parasympathetic ganglia.

The Cranial Part:
It consists of all the nerves and outlets that one, associated with the brain and the head.

The Sacral Part:
It comes from the extreme lower end of the spinal cord.

Question 7.
Describe the location of the brain.
Answer:
He conducted several experiments on rats and other animals to find out the effect of the removal of various parts of the cerebrum on psychological purposes.

  • Several experiments on rats and of the problem and cerebral lessons; and
  • the effects of destruction on various sizes and locations on the maze learning habits are notable.

The findings of these studies showed an intimate relationship between the difficulty of the problem and the effect of cerebral lessions. There was an increase in error while learning when cortical destructions 1 were higher. Lashley finally concluded that the quantity of the lesson was a significant factor in retardation in learning. lie found that many problems like the skill of ordinary maze learning can be acquired equally well with one part of the cortex as with another.

He further found that there was a positive relationship between the amount of cortex and the difficulty of the task that is, as the difficulty of the task increases the greater amount of cortex is required to solve it. Even when half of the cortex was removed, simple tricks were learned equally quickly, but difficult problems could not be solved.

In one experiment by Lashley (1929) adequate training was given to monkeys to open the door by handling a latch. After learning was complete the monkeys were decorticated. Some portions of the frontal lobe were removed by surgical operation, without any danger to the life of the monkey. After decortication, it was found that some portions of the brain are at least responsible for certain work.

But later he also found that money could be educated and they could relearn the previous learning after decortication. From these experimental findings, he established two principles to explain the functional localization of the brain, that is, whether the brain acts as a whole or in parts.

Principle of Equipotentiality:
Lashley was of opinion that complex learning does not depend upon the definite structure of a specific area of the cortex. On the other hand, he noted that complex learning depends upon the total organization of the cortex. The principles of equipotentiality hence mean that with some very specific exceptions.

One part of the cerebral cortex is potentially the same as another part in its functional capacity related to the learning process. In other words, the capacity of the uninjured or intact part of the brain for functioning as a substitute for other parts in case of emergency is called the principle of equipotentiality.

All parts of the cortex, therefore, are equal potential for the learning function. Thus, Lashley in his book Brain Mechanism and Intelligence (1929), has remarked, “The term equipotentiality I have used to designate the apparent capacity of the intact part of a functional area to carry out with or without reduction in efficiency, the functions which were lost by destruction as a whole.

This capacity varies from one area to another and with the character of the functions involved. It probably holds only for the association areas and for function more complex than simple sensitivity or motor coordination.”

The Principle of Mass Action:
To Lashley, the principle of mass action meant that the brain fundamentally functions as a hole. He said that the more the cortex available, the better would be the learning capacity. In this connection, he has pointed out that the animals with various amounts of their cortices removed. Showed a general reduction in sensitivity, aggressiveness, and in exploratory activity in puzzle-born learning situations in comparison to their normal counterparts.

What he intended to say is that the cerebral cortex seems to be responsible for the characteristics of one’s behavior as a whole. That is why the removal of one part of the cerebrum affects learning in a general manner. The most important generalized function of the brain is to establish associations between our various present and past experiences.

The association area of our brain contains all our experiences and it is because of this connection of experiences that our mind acts as one unit. Franz later found that the amount of brain has also got a major contribution to higher psychological activities and complex learning processes. He noticed that if a small portion of the cortex will be decorticated, it will not decrease the activities undertaken by this part.

The other parts of the brain will take charge of it and the work will be somehow managed. But if a longer part is taken away there will be a deterioration in learning and other complex mental activities. It is thus proved that more amount of cerebral cortex is needed for higher psychological processes like learning, application of intelligence and judgment, synthesizing ability, thinking, problem-solving, perception, etc.

This principle, therefore, states that the brain acts as a whole or in a mass. The principle of equipotentiality and mass action is confirmed and supported by many experimental studies on apes, monkeys, human beings, etc. These principles are also confirmed by the findings of studies on human beings whose parts of the brain were injured or damaged by disease or accident.

Analysis of these principles and the experimental findings in their support do prove that simple sensory-motor functions may show a relatively high degree of localization while complex and higher-order mental activities require less localization and more mass action. Therefore, it would probably be more appropriate to conclude that the brain acts in widespread patterns.

patterns that include many cortical areas and their connecting association fibers. Loss of any large portion of the cortex will disturb the interaction of parts and break up the usual pattern. It is the general type of function. So, we have to accept somewhere between the two. In ordinary simple work, the brain acts in part.

But in higher-order activities and higher mental processes, coordinating the integrative function of the entire brain is essential. So, in such cases the brain functions as a whole. There is evidence for the localization of sensory and muscular movements. There is some indication that the frontal lobes are concerned with the management of planned activity and that the rear half of the brain is more concerned with knowing and understanding things.

Learning seems to be an unlocalized function and adjustment of the organism for the total situation and for a goal is probably a function of the entire cerebrum. It would, therefore, be not appropriate to generalize about the principles of complete equi-potentiality of the functions of various areas of the cerebrum. Besides, the evidence derived from rats, cannot be applied with equal confidence in human organisms.

Experiments on monkeys show a much greater loss in the ability to learn when their frontal lobes were destroyed than the damage elsewhere. Some cases of human subjects also indicated that there is a considerable degree of specificity in the cortex. However, further research in this area is necessary to draw a generalized conclusion on the functional localization of the brain.

Question 8.
What are the methods applied to study the brain?
Answer:
Some of the important methods to study the localization of functional areas of the brain are discussed below:
Anatomical Method:
In this method, the anatomist attempts to find out various nerve pathways by observing the nature of neural tissues under the microscope. By this method, the anatomist not only learns the origin and termination of different nerve fibers but he also finds out what sense organs send fibers where and what parts of the brain send motor fibers to the spinal cord. This method only finds out the structure of the brain and spinal cord. The functions of the brain and the spinal cord are not traceable by this method.

Method of Extirpation or Aplation Method:
Extirpation means to destroy or cut off. In this method, a particular part of the brain is destroyed or cut off and its effect is studied on the functions of the brain or human behavior. The behavior of the organism is carefully observed and recorded. Then it cuts off a specific part of the brain and observes its effects on the behavior of the ‘O’, that is whether it changes his behavior or not.

Action Potential and Electrical Recording Method:
Neurons produce electric currents when they conduct and the potentials underlying them can be recorded with a cathode ray oscilloscope. By correlating the parts having the greatest electrical activity with the nature of the stimulus one can find out which area of the brain is involved in various types of sensations and how the body surface is represented on surfaces in the brain.

Method of Stimulation:
It is a direct method. Different parts of the brain are stimulated with mild electric currents. While making brain operations on patients an introspective report is taken from the patients on the sensations they experience while stimulation. Using this method, functions of different parts of the brain can be located.

Chemical Method:
In this method certain chemicals are used to distinguish axons from cell bodies; certain parts of neural tissues from others to observe their specific functions. Similarly, it is used to find out which axons are part of the same neurons. Otherwise, because of their complexity, it is not possible to say these things merely by looking through a microscope. Behavioral changes are also observed by using various chemicals on the external and internal parts of the brain.

Scanning Method:
Today medical science has made rapid progress, thanks to the continuous and meaningful research in the area, particularly in the West. Scanning means taking pictures intently of all parts. With the development of scamming methods, new models of X-ray machines, and computers, the functions of the brain are being studied in a very scientific and organized manner.

Through scanning, it is possible to get an X-ray picture of every millimeter of the brain. Scanning of the brain helps in knowing the damages and destruction made to the brain because of accidents. Alzheimer’s disease, Korsakoft’s Syndrome, and many other diseases like a brain tumors.

There are different types of Scanning like Cat Scans, Pet scans, and MRIs, etc.
Cat Scan:
The Cat Scan method is used when one is interested to know and analyze the minute details of the functioning of the brain of an individual. Scanning of the brain is recommended particularly when the doctor has to diagnose to patient.

Question 9.
Describe the structure of the human brain.
Answer:
The Brain:
Modem scientific psychology recognizes that is the brain, not the heart or soul which guides human behavior. Recently, technological innovations such as the electron microscope and brain scanning systems have led to an explosion in a number of new theories and tests of how the brain works. It has been found that an adult brain weighs about 1.36 kg and contains around 100 billion neurons.

The brain receives one-fifth of the blood pumped by the heart. If deprived of oxygen for 3 to 4 minutes, the brain cells are irreparably damaged. Brain investigation reveals that while some mental functions are widely distributed among different areas in the brain, man activities are highly localized.

Different areas in the brain are specialized for specific jobs. Our brain controls almost all the activities that we do, except the reflex activities which are controlled by the spinal cord.

Structure of Brain:
With the development of the human embryo inside the mother’s womb, the nervous system begins forming as a long, hollow tube in the back of the embryo. After three weeks of conception, cells making up the tube differentiate into a mass of neurons, most of which then develop into three major regions of the brain – the hindbrain, which is adjacent to the top part of the spinal cord, the mid-brain, which rises above the hindbrain and the forebrain, which is the uppermost region of the brain (see fig. 4.6).

Hindbrain:
It is the lowest portion of the brain located at the rear of the skull. In other words, the backside of the brain is called the hindbrain. It has three subdivisions medulla, cerebellum, and pons. The medulla begins where the spinal cord enters the skull. It is also called the medulla oblongata.

This structure is located at the lowest portion of the brain stem. It is a link between the brain stem and the spinal cord. The medulla helps to control our breathing and regulates reflexes which allow us to maintain an upright posture. It also controls some vital and autonomic functions such as respiration, circulation of blood digestion of food, etc.

It has some roles in sneezing, sleep, and coughing also. The cerebellum extends from the rear of the hindbrain, just above the medulla. It is also called the ‘Tittle brain’ because it is a miniature version of the cerebrum. Its outer surface looks grey and the interior white. It consists of two rounded structures thought to play important roles in motor coordination (Middleton & Strick, 2001).

Its vital function is to control body balance and posture. It also controls biological rhythm or perception of time. Injury to the cerebellum may lead to a lack of motor coordination, stumbling, and loss of muscle tone. When the cerebellum is damaged, movements become uncoordinated and jerky.

Extensive damage to the cerebellum even makes it impossible to stand up. It also stores the memory of movement patterns so that we do not have to concentrate on how to walk, dance, or ride a bicycle. Moreover, the cerebellum is associated with coordinating movements, controlling posture, and maintaining equilibrium.

Describe the structure of the human brain Q9

The Pons lies between the medulla and the midbrain. It is a Latin word, which means ‘bridge’. But it does not look like a bridge. It is so named because of the bundle of nerves that passes through it. the pons region connects to the cerebellum and is involved in dreaming and waking. It contains several clusters of fibers involved in sleep and arousal (Kolb, Whishaw & Terao: 2003, 2004). Moreover, the pons transmits information about body movement and is also involved in functions related to attention, sleep, and alertness.

The Midbrain:
The shortest part of the brain is the midbrain. It is also the topmost part of the brain which is located in the central region. It is just a tube-like structure. The outside of the midbrain looks white and the inside looks grey. Through this tube, a fluid-like substance called cerebrospinal fluid passes which provides nutrition to the brain. Besides providing nutrition, it has got sensory and motor pathways. The midbrain contains primitive centers for vision and hearing and plays a key role in the regulation of visual reflexes.

Describe the structure of the human brain Q9 1.1

Two systems in the midbrain are of special interest – One is the reticular formation or Reticular Activating System (RAS) and the other one is the brain stem, the RAS begins in the hindbrain and ascends through the region of the midbrain into the lower part of the forebrain. It is a network of neurons crossing each other.

The size of RAS is just like a small finger of a man. RAS has two parts ascending reticular system and descending reticular system. The ascending reticular system sends impulses to the cerebral cortex and the descending system sends impulses downward to the RAS. RAS also receives impulses from the cerebral cortex.

Describe the structure of the human brain Q9 1.2

Electrical stimulation of RAS awakens sleeping animals. If the RAS is damaged, the animal may not die but will sleep forever. This kind of sleep is called comatose or simply coma. Once it is destroyed, it does not recover. RAS also acts as a relay station for emotional behavior. The RAS is less activated during sleep. It is connected with the cerebrum by receptors and effectors. Further, it plays an important role in selective attention and filtering of information through learning.

The brain stem is so-called because it looks like a stem (Carlson, 2001). It is the most ancient part of the brain. The brain stem connects with the spinal cord at its lower end and then extends upward to encase the reticular formation in the midbrain. Clumps of cells in the brain stem determine alertness and regulate basic survival functions, such as breathing, heartbeat, and blood pressure.

The Forebrain:
It is the most important part of the brain. Virtually it possesses all the parts concerned with the perception, and coordination of behavior patterns including those of emotion, motivation, learning, memory, language, and thinking. The significant parts of the forebrain are the thalamus, hypothalamus, limbic system, and cerebrum.

Thalamus:
Thalamus is located almost in the exact center of the human brain. It consists of an egg-shaped cluster of neurons. Thalamus connects the cerebrum with peripheral parts of the body. All the nerves come and go through it. So it is an important relay station for incoming sensory impressions from all parts of the body. Further, it is called the central switchboard of the brain.

Describe the structure of the human brain Q9 1.3

The main function of the thalamus is to send incoming sensory impulses to respective parts of the cerebral cortex. Most neural input to the cerebral cortex goes through the thalamus. Thalamus is also involved in controlling sleep and attention in coordination with other brain structures, including RAS. When the cortex wants to inhibit or control certain automatic activities, it sends the impulses to the thalamus.

Basal Ganglia:
Just above the thalamus and under the cerebral cortex lie large clusters of neurons called basal ganglia. The basal ganglia work with the cerebellum and the cerebral cortex to control and coordinate voluntary movements. These large clusters of neurons or ganglia enable people to engage in habitual behaviors such as riding a bicycle. People with damage to basal ganglia suffer from either unwanted movement, such as constant writing or jerking of limbs, or too little movement, such as the slow and deliberate movements of those with Parkinson’s disease.

Describe the structure of the human brain Q9 1.4

Describe the structure of the human brain Q9 1.5

Hypothalamus:
Hypothalamus is a small forebrain structure located just below the thalamus. It lies at the base of the cerebrum. It regulates the functioning of the Autonomic Nervous System. Hypothalamus monitors three pleasurable activities eating, drinking, and sex – as well as emotion, stress, and reward. It also directs the endocrine system. Hypothalamus acts as a regulator of the body’s internal state.

It also plays an important role as an integrative location for handling stress (Hayashi and others, 2004). Much of the integration is accomplished through the hypothalamus’s action on the pituitary gland, an important endocrine gland located just below it. If certain areas of the hypothalamus are stimulated electrically, a feeling of pleasure results.

The Limbic System:
The limbic system is composed of a group of structures that is found in all mammals, sometimes called the old brain. Only mammals and reptiles have limbic systems. It is a ring-like structure having several other structures. The limbic system is structurally interconnected with the hypothalamus. So it is involved in the drives of hunger, sex, aggression, and some of the behaviors regulated by the hypothalamus.

The three principal structures in the limbic system are the amygdala, hippocampus, and septum. The amygdala has an important role in aggression. It is involved in memory, emotions, and certain basic motivations. The damage to the amygdala causes an animal to be less fearful, over-curious, hypersexual, and more exploratory.

Question 10.
What is the endocrine gland and discuss the functions of the endocrine system?
Answer:
The endocrine system is a set of glands that regulate the activities of certain organs by releasing their chemical products into the bloodstream, like the nervous system, it plays a crucial role in our behavior and development previously, the endocrine system was considered separate from the nervous system.

However, today neuroscientists know that two systems are interconnected. The endocrine system consists of ductless glands which secret complex chemical substances called hormones, directly into the bloodstream. The human body is not only under the control of the nervous system but also of a complementary system of hormones.

This system is controlled by Autonomic Nervous System (ANS) activity and like ANS, it is not under conscious control but regulated by the body itself. It helps in maintaining bodily homeostasis. Hormones are involved in different bodily functions and behaviors. They influence body growth, sexual development arousal, mood, and metabolism.

Endocrine or ductless glands are stimulated in 3 ways:

  • by chemical level in the bloodstream,
  • other hormones and
  • nerve impulses from the Bram

Once secreted into the blood, hormones are promoted it’s their bodily targets. This system not only sustains our slow and continuous bodily processes but also helps us to respond to crises. During an emergency, the Iannone ‘adrenaline’ is released into the bloodstream, energizing our body for quick defensive action for ‘ fight’ or ‘ flight’.

‘Hormones’ are generally called ‘the messengers of life’ because their influence is diverse but specific (Carpo 1988). Different hormone factories ‘sites of our body produce chemicals that influence a variety of bodily processes. A small structure of the limbic system, the hypothalamus, is the brain center in charge of the endocrine system.

In the hypothalamus, specialized cells receive messages from other brain cells committing to release a number of different chemicals. These chemicals influence the adjacent pituitary gland, the so-called master gland which can either stimulate or inherit the release of hormones from other glands.

The functions of the Endocrine System:
The important functions of the endocrine system are discussed below:

  • The pituitary gland
  • Thyroid gland
  • Parathyroid
  • Adrenal gland
  • The pancreas
  • The Gonads

The Pituitary Gland:
Although the pituitary gland is situated within the cranium, still it is a part of the endocrine system, rather than the nervous system. This gland is popularly known as the master gland. It is located in a small bony hollow at the base of the brain. Centre of the skull. The size of the pituitary gland is very small. But control growth and regulates other glands. This pea-sized gland is controlled by the hypothalamus.

The pituitary gland has:

  • anterior
  • posterior pituitary secretions.

Anterior:
The anterior pituitary secretions help growth. Hypersecretion of it causes gigantism and a rugged personality.

Posterior pituitary secretions:
The posterior pituitary gland hormone raises blood pressure, regulates metabolism, and increases the contraction of smooth muscles in the intestine and uterus.

Thyroid Gland:
The thyroids are located in the neck at either side of the ‘Adam’s apple’. These glands produce thyroxin, which influences the body’s metabolism rate. It also helps to control the rate of physical growth and influences the structure and functions of the nervous system.

Question 11.
What is the cerebrum and describe how does the brain function?
Answer:
The Cerebrum:
The cerebrum or cerebral cortex is more highly developed in humans than in any other animals. The cerebral cortex is divided into two halves or hemispheres. It is the highest region of the forebrain and is the most recently developed part of the brain in the evolutionary scheme. In humans, the cerebral cortex covers the lower portions of the brain like a large cap.

The cortex is greatly convoluted with lots of grooves and bulges which considerably enlarge its surface area. It is connected with other parts of the brain. Literally, millions of axons connect the neurons of the cerebral cortex with those located elsewhere in the brain.

What is the cerebrum and describe how does the brain function Q 11

The cortex looks gray since it consists largely of cell bodies and unmyelinated fiber. A very depressed or fissure divides the cerebrum into two equal halves – the left hemisphere and the right hemisphere. The left hemisphere is connected with the right-hand side of the body. The right hemisphere is connected with the left-hand side of the body.

The two hemispheres are connected with each other by a thick fiber bundle known as the corpus callosum. Each hemisphere is divided into four parts or lobes by two fissures – the frontal lobe, the parietal lobe, the temporal lobe, and the occipital lobe. However, the occipital lobe is not clearly demarcated. It is located at the rear of the brain.

The frontal lobe is that portion of the cortex behind the forehead which is involved in the control of voluntary muscles, intelligence, and personality. The frontal lobes of humans are especially large when compared with those of other animals. This lobe is primarily responsible for the planning, execution, and control of movements.

Without intact frontal lobes, humans are emotionally shallow, -5 distractible, listless, and insensitive to social contexts (Hopper & Teresi, 1992). Individuals with frontal lobe damage become so distracted by irrelevant stimuli that they often cannot carry out some basic directions. An important part of the frontal lobe is the prefrontal cortex, which is at the front of the motor cortex.

It is believed to be involved in higher cognitive functions such as planning and reasoning (Manes & Others, 2002). Neuroscientists refer to the prefrontal cortex as an executive control system because of its role in monitoring and organizing thinking (Owen, 1997). The parietal lobe is located at the top and towards the rear of each hemisphere.

It is involved in registering spatial location, attention, and motor control. This cortex receives information from the somatic senses. Therefore, this area is specialized for touch, pressure, and pain. On the whole, it controls incoming sensory information. The portion of the cerebral cortex just above the ears is the temporal lobe. It is involved in hearing, language processing, and memory.

The temporal lobes have a number of connections to the limbic system. Individuals with damage to the temporal lobes can not file experiences into long-term memory. The area of recognition of music is situated in this area. If this area is destroyed, an individual may lose the taste sensation.

The occipital lobe is located at the back portion of the brain. Its shape is triangular. It is the seat of the visual sensation. The most important functional area located in this lobe is the visual area. The retina is connected to this area. A stroke or wound in the occipital lobe can cause blindness or wipe, out a portion of the person’s visual field.

In the cerebral cortex, there are some areas that are not directly concerned with sensory or motor functions. These are called association areas. Each lobe is having an association area. They play significant roles in various sensory systems and in transmitting sensory input to programmers for motor output. Further, the association areas are involved in complex cognitive activities such as thinking, reasoning, learning, remembering, etc.

How does the brain function?
Very often, the question arises whether or not the brain functions as a ‘whole’. Physiological psychologists are trying to answer this question since the days of Johannes Muller. There are differences in views. A group of experts believed that each part of the cerebrum had a definite function. Another group believed that parts of the brain are functionally interchangeable. Modem findings indicated that the brain functions in parts as well as as a whole.

The experimental findings of Franz and Lashley on localization are expressed in two theories:

  • the theory of equipotentiality and
  • the theory of mass action.

Theory of Equipotentiality:
The theory of equipotentiality suggests that all parts of the cortex are equal potential enough for simple learning functions. Lashley has conducted a good number of studies on animals. According to him, complex learning does not depend upon the definite structure of a specific area of the cortex, rather, complex learning depends upon the total organization of the cortex.

This principle suggests that with some very specific exceptions, one part of the cerebral cortex is potentially the same as another part in its functional capacity related to the learning process. Therefore, all parts of the cortex are equal potential for learning function.

The Principle of Mass Action:
The principle of Mass Action reveals that the brain fundamentally functions as a whole. The more parts of the cortex an available, the better would be the learning capacity. In his study, Lashley found that animals having decorticated cortex demonstrated a general reduction in sensitivity, exploratory activities, and aggressiveness. The removal of any part of the brain affects the learning process.

Later, Franz found that the amount of brain has got major contributions to higher psychological activities and complex learning processes. The principles of Mass Action and Equipotentiality were confirmed and supported by many experimental studies on apes, monkeys, human beings, etc.

These principles were also confirmed by the findings of the studies on human beings whose parts of the brain were injured or damaged by disease or accident. Probably it would be more appropriate to conclude that the brain acts in widespread patterns, which include many cortical areas and their connecting association fibers.

Damage to the large portion of the cortex would certainly disturb the interaction of parts and break up the usual pattern. It is true that the brain acts in part in ordinary simple work. But in higher mental activities and higher mental processes, the coordinating and integrative function of the entire brain is necessary. In such cases, the brain functions as a whole. However, to draw a generalized conclusion on the functional localization of the brain, further research in this area is essential.

Question 12.
What is the peripheral Nervous System?
Answer:
The peripheral nervous system is composed of all the neurons forming the nerve fibers that connect the CNS to the rest of the body. It consists of sensory and motor neurons that transmit messages to and from the central nervous system. Our brain will be isolated from the world without a peripheral nervous system. This system has two divisions.

  • Somatic Nervous System.
  • Autonomic Nervous System.

These are described below:
What is the peripheral Nervous System Q12
Somatic nervous system:
The somatic nervous system is the first part of the peripheral nervous system. It is under voluntary control and regulates the actions of the skeletal muscles of the body. The somatic nervous system has both sensory neurons and motor neurons. The sensory neurons mn from our sense organs toward the central nervous system for perception and learning etc.

On the other hand, the motor neurons carry messages from the brain to the striped muscles of the body for activities. Action like moving our legs or hands, running, jumping, and riding is possible by the somatic nervous system. On the whole, the somatic nervous system controls the striped muscles of our body.

What is the peripheral Nervous System Q12 1.1

Autonomic Nervous System (ANS)
The very word autonomic means self-regulating or independent. ANS is the second part of the peripheral nervous system. It is involuntary and governs activity, which is not normally under the direct control of the individual. The ANS works even when we are asleep. ANS sustains basic life processes.

The ANS operates constantly, regulating bodily processes we do not usually control consciously, such as respiration, digestion, and arousal. On the whole, the autonomic nervous system is called as autonomic because many of the activities it controls are autonomous or self-regulating and continue even when a person is asleep or unconscious.

The autonomic nervous system (ANS) is subdivided into the sympathetic and parasympathetic nervous systems. Both these divisions have survival functions for which the autonomic nervous system is called as survival nervous system. The ANS is intimately connected with the spinal cord.

The sympathetic division tends to act as a unit. It is exciting in emotional situations. The sympathetic division governs responses to stress in emergencies when action must be quick and powerfully, energized. This is the ‘fight or flight response system. In short, the sympathetic nervous system is the division for emergency survival.

For example, during emotional excitement, digestion is stopped, heart rate is increased, blood flowing to the internal organs is directed to the skeletal muscles and the endocrine system is stimulated to release several chemicals which increase the effectiveness of the entire motor system. The sympathetic division energizes us to respond to a stressor quickly.

But the parasympathetic division monitors the routine operation of the body’s internal functions. It is concerned with projecting and conserving the body’s resources, preserving normal functions, and maintaining a calm emotional state. This division returns the body to calmer functioning after sympathetic arousal. Unlike the sympathetic division, the parasympathetic division tends to affect one organ at a time.

In short, whereas the sympathetic system is activated during violent emotions, the parasympathetic system is dominant and active during normal times or during quiescence. Activation of this system slows the heartbeat, lowers blood pressure, and conserves as well as protects bodily resources. The sympathetic and parasympathetic systems do not compete with one another, rather they function in a coordinated manner.

Question 7.
Illusions.
Answer:
Illusions are wrong perceptions. Illusion is the wrong or mistaken interpretation of a sensory experience.

Question 8.
Hallucination.
Answer:
It has been already discussed how the illusion is a normal affair. Hallucination which is also a type of perceptual error is experienced by mentally disturbed abnormal persons. Hallucinations may be visual, auditory, olfactory, tactual, gustatory, etc. Hallucinations represent our inner conflicts, fears, anxieties, and mental imbalances. Visual hallucination follows auditory hallucination.

Question 9.
Symbolic process.
Answer:
Sensory stimulations arouse certain neural activities which have their trace in the nervous system. These are popularly known as neural traces. These traces act as symbols or substitutes for the original stimulus or experience. These symbolic images help us while perceiving something. This symbolic process is activated by any experience in an image.

Question 10.
Size Constancy.
Answer:
The size of a stimulus varies with the change in distance between the percept and the perceiver. A tree that is usually perceived at a distance of 5 feet will look very small. Martin did an experiment on size constancy. Considerable constancy was indicated by the observer in the perception of the size of the blocks. But in spite of this significant difference in the sense of impression, we perceive the tree to be of its usual size.

Question 11.
PHJ Phenomenon.
Answer:
Phiophenomcnon is an illusion of movement. When objects are more in quick succession, they appear as one continuous unit or whole. In an experiment, the phenomenon is when two more lights are of optimum brightness, size, and distance. Human adults, children, and animals all are used by this type Of illusion of movement. It is also due to the basic characteristics of the brain activity involved in perception.

Long Type Questions With Answers

Question 1.
What is the importance of Audio Visual aids? Explain?
Answer:
Sensory experiences form the foundation of intellectual growth. It is a common practice with teachers to communicate knowledge by means of written and oral languages. But language has some limitations which result in bearing difficulties. The modem educationist, therefore, recognizes of audio-visual aids to remove learning difficulties by ensuring concreteness and dynamic interests. The most abstract concept can be presented to the pupils in a concrete way by means of more than one aid. Some of the distinct advantages claimed for audio-visual aids are discussed below.

Audiovisual aids are the best attention compellers:
Those arouse interest and motivate the pupils to action and stimulate physical and mental activity.

Audio-visual aids give variety to the classroom atmosphere:
Variety is always attractive and attention-getting to the child. It breaks the monotony and sustains the attention of the child for a longer period.

Audio reduces verbalism:
Audio-visual aids reduce verbalism or the use of unnecessary language, words and phrases and contribute towards clearness of perception and accuracy in observation

Aids extend freedom:
Aids provide some freedom to the child. The child may freely observe, talk, laugh, question, and comment and may act in a natural manner. An atmosphere of friendliness and cooperation proves inside the classroom between the teacher and the students.

Aids provide first-hand experience:
Audio-visual aids provide first-hand experience when the students see a demonstration, handle the apparatus, perform, the activity operates a model specimen, draw a picture or diagram and manipulate the situation.

Aids being a vivid reality in the classroom:
Aids provide some naturality end reality in the classroom. The students from some images of real objects when they observe. This reduces abstractness and increases Concentrate concepts.

Aids may represent actual sources :
In many cases, actual objects may not be brought to the class for various reasons expensiveness, oversize, danger in handling or difficulty in the collection. In such a situation, the teacher may improvise some aids to represent the real object. For example, it is not possible to bring an elephant to the class, but the teacher can use a mode of the elephant past objects, and distant objects represented through improvised aids.

Aids provide an opportunity to inculcate a scientific attitude and give training in the scientific method:
Children become more sincere, industrious and systematic, they develop the powers of critical thinking, reasoning, and judgement. They develop an enquiring bent of mind through questioning and argument.

Question 2.
Discuss the different types of audio-visual aids and their functions?
Answer:
For using the senses children different aids may be used by the teacher. On the basis of the senses, the teaching aids may be broadly divided into the following three categories:

  • Auditory aids
  • Visual aids and
  • Audiovisual aids

Auditory aids :
These aids involve the use of the auditory sense or the ear. The children by hearing various sounds can gain some experiences. Instruments used in such auditory aids are radio, tape recorder, and gramophone records.

Visual Aids:
These aids are meant to utilize the sense of vision, (eye) and therefore are called visual aids. Examples of such aids are many
(a) Charts, globes, specimens
(b) Motion pictures, slides, films
(c) Maps, diagrams, sketches, .models, pictures
(d) Flannel graphs, bulletin board
(e) Printed materials, newspapers

Audio-visual aids:
These aids involve the use of both auditory and visual senses and can be simultaneously heard and seen. Therefore, these aids are called as Audio-visual aids. These includes
(a) Sound motion pictures
(b) Television
(c) Dramatic plays

Broad classification of instructional aids:
Broadly Instructional aids can be classified into three categories, as
(a) Projected aids
(b) Non-projected aids and
(c) Activity aids

Projected Aids:
When a projected aid is used an enlarged image of the material is t projected on a screen kept at a distance from the projector. The room is either totally or partially darkened. A projected aid is bound to be more effective since a darkened room reduces destruction and the bright image on the screen secures the attention of the audience. Colour will make the aid more attractive motio^ more dynamic and motion associated with sound will be most effective.

Projected’aids are suitable for small as well as large groups. Projected materials are shown viewers by means of various projectors. A list of the projected materials is given below. Projected materials include, books, diagrams, pictures, then opaque objects, slides, motion pictures etc. and projectors like Epidia scope, slides projectors, film projectors, motion picture projectors etc.

Non-Projected Aids :
These aids cannot be projected on the wall or on the screen. Such aids individually or in groups can be shown to the students teaching. These can be too, used on the blackboard or classroom walls. All these non-projected aids generally are visual aids.

Examples of these aids are as follows :

  • Graphic aids – line graphs, bar graphs, histograms, pictorial graphs
  • Diagrams with symbols and labels
  • Pictures with various colours, shapes and sizes.
  • Maps, illustrations, flat pictures
  • Posters, cartoons, sketches
  • Charts, models, specimens
  • Globes, improvised materials
  • Display boards, flannel graphs, bulletin board

Activity aids:
Modern educations give stress on learning by doing or learning by experience. The students can get three types of experience during the teaching-learning process.

Direct Experiences:
It consists of having, immediate sensory content with the actual object or place. It is the purposeful experience that is seen handed tested, touched, felt and smelled. Such experiences give first-hand information and are thus the most educative type of experience.

Various experiences :
It refers to the experience gained through the represented or substituted materials models, pictures and specimens, photographs, exhibits and posters. It is not always possible to get direct experiences.’There are situations, objects and phenomena where a representation is better for instructional purposes. For, example, an atom cannot be seen directly but can be studied only through a model or diagram.

Symbolic experience :
Symbolic or abstract experiences are afforded through verbal symbols – oral or written. These experiences occur at the conceptual level. The verbalism is the quickest method representing an experience, at times it becomes more confusing and abstract. These sensory experiences are such effective than, verbal ones. The more will be the number of direct experiences, the more effective will be the learning of a child. Therefore, the teacher must plan activities that can provide first-hand information to, the learners.

Question 3.
Discuss the activity aids and activities that provide direct experiences to pupils in their learning?
Answer:
From activities, the sensory experiences are gainer which becomes more effective for the learning of a child. The activities that provide direct experiences are as follows.

Field trips:
The learning process should not confine to the four walls of the classrooms. The pupils should be taken away from the school to visit places of educational importance located nearby the school or in the community. They can get some first-hand information regarding the objects or places written in the book or told by the teacher.

Such field trips may be organized to enable the pupils to visit local schools, museums, hospitals, gardens, parks, radio-station, TV stations, telephone exchanges, forests, airports, factories, agricultural and industrial forms, natural spots, and places of such categories situated in the locality. Through field trips, children gather experiences of locality and community life.

Excursions:
Excursions are undertaken mostly for recreation, and pleasure learning experiences outside the local community. The pupils have some knowledge and information the visiting places and the educational information becomes first-hand. They correlate school life with the outside world. Generally, children can be taken to visit lakes, rivers, mountains, forest parks, historical towns, monuments, places of historical importance, airports, zoos, etc. scientific and industrial farms and other places.

Exhibitions:
The exhibitions arranged in schools are usually planned to communicate something interesting educative and valuable to students, parents and the public. Parents and visitors can have an idea of the talents present in the pupils. Self-activity is fostered in the children who take part in the exhibition.

Individual interests, fancies, and skills are exhibited by the participants. Exhibitions are effective models of mass communication instruction on a large scale. The exhibition must be an annual affair. All students of the school must cooperate and contribute something valuable. Students must be trained as to what features of the exhibit must be stressed while giving explanations.

School museums:
Museums are the wonderful media for mass education. These institutions collect passive original objects and specimens available in the locality. The students must be encouraged to contribute exhibits to the museum. Each exhibit kept in the museum must be properly labelled giving details about the exhibit and the names of the donor.

Nature study:
The pupils can leam many things from the nature and environment through observation. They can get a comprehensive idea of plant and animal life.

Community study:
Community resources provide educational learning situations to the pupils. Through community study, the pupils can understand the value of social life, develop citizenship and civic responsibility achieve vocational understanding and economic self-sufficiency. The child leams what is relevant to him. The school must provide a chance for children for talks to and visit postmen, policemen, political leaders, social workers, farmers, and other people, who help the community. Community study must include visits interviews, participation, field trips and journeys Resource persons may be invited to the school to deliver talk to the pupils.

Creative activities:
Creativity in children is manifested in a number of activities. By observing these activities the pupils can leam many things and can also get many direct and concrete experiences are as follows.

  • Music, dancing, songs
  • Dramatisation
  • Arts and crafts,
  • Play way. activities, like mock

parliament, and assembly, mock elections, students, self govt., school co-operatives, folk music and folktales etc.

Question 4.
What are objective-based and objective-type test items? What are the different types of objective tests in Mathematics or any subjects?
Answer:
Tests are essential features in the teaching-learning process. They are used for various purposes. The main purpose is prognosis, diagnosis and survey. Very often we talk of objective-based tests and objective tests. They are not the same. The meaning is different objective-based tests are there which are based on specific objectives. At the beginning, based on specific objectives. At the beginning of the teaching-learning process set certain objectives.

In the end, we have to assess the extent to which broken pupil behaviour patterns and test items asked to evaluate each behaviour pattern. Such test items are called objective-based tests. But, objective test items are those which elicit answers in either a word or in number. Now adays educationists put emphasis on objective test items instead of essay-type items. Various types of objective tests are used.

Alternative response type test :
It is the testing situation in which a pupil has to choose one of the two persons. The items can be answered either ‘yes’ or ‘no’ or by true or false. Such items can even be answered by putting either a tick mark or a cross mark. Example – Some of the following statements are true as some are false. Write ‘T’ against the statement and ‘F’ against false statements in the space provided for Q.

  • The three angles of a triangle are 360°.
  • The sum of two sides of a triangle is greater than the third side.
  • The difference in the length of the two sides of a triangle is smaller than the third side.

Completion type :
In this type, items consist of a sentence or statement in which there is a blank space which is to be filled up by the pupils. Alternate responses may be supplied in the bracket among which the pupils have to choose the correct one.
Example – Fill in the blanks:

  • The square root of 256 is _____.
  • The sum of three angles in the triangle is equal to ______.

Matching type :
In this type of test, two-column of items are given. Each item on the first column is to be matched with the corresponding items on the sound column.
Example Match each item in column ‘A’ with its related item in column‘B’

A B
Reflex angle 45°
Right angle 90°
Acute angle 140°
Obtuse angle 30°

Multiple choice tests :
In this type of test items with each question are given 4 to 5 possible answers among which only one is the correct answer. The pupils have to choose the correct answer. This type is considered to be the best of objective-type test items.
Example – Choice the correct answer from the four alternatives given below which of the following is correct is a right angle triangle?
(a) All angles are right angles
(b) Two angles are right angles
(c) Only one angle is a right angle
(d) No angle is right angle:

Question 5.
What are the different types of items used in classroom evaluation? What is objective-based evaluation?
Answer:
Objective-based evaluation :
The evaluation process should be based on the intended learning outcomes. The evaluation process should be organized to access the extent to which the instructed objectives are achieved through instruction. If it is found through evaluation that some objectives have not been achieved to the desirable extent.

It will be inferred that the learning experiences and activities provided and the methods of teaching adopted have not been sufficient or appropriate from this consideration evaluation becomes the basis for continuous review and revision. the entire process of education fills the desired level of efficiency is reached.

Types of test items :
A variety of evaluation tools and techniques are needs to be used for making the evaluation process effective. The most frequently used tests that have a direct relationship with classroom instruction, are the achievement tests. The teacher makes use of these tests to access the achievement of pupils in various school subjects.

A science teacher in a similar manner constructs and uses achievement tests at different times. A variety of test items can be asked by the teacher. The different types of test items can be classified in the following manner. The test items include Essay type short answer type, very short answer type and objective types.

The objective-type test questions include:

  • Simple recall/fill in the gaps type.
  • Alternate response type
  • Multiple choice type
  • Correct the error type
  • Matching type
  • Master lost type
  • Analogy type

Essay-type tests :
The items that require a long answer are called essay-type items.
Example:
Describe the preparation, properties and uses of carbon dioxide. Explain with a suitable diagram, the cell division (mitosis, in plants and animals)

Short answer type:
The short answer type items usually require answers within a paragraph of about 50-75 words.
Example:
Write down the chemical proportion of chlorine, Distinguish between a solar eclipse and a lunar eclipse.

Very short answer type :
These items require answers within 10-20 words. State two physical properties of oxygen gas, Define buoyancy.

Objective tests :
The objective-type items require answers in a word or a number or a tick mark or the like. As has been mentioned in the classification tables are a large variety of objective-type items. Some of such items with examples are discussed below.

  • Simple recall fill in the gaps type – Hydrogen is prepared in the laboratory by the reaction of _______
  • A rod made of _______ and H, SO. is, used as an electrode in the dry cell.

Fill in the gap:
Type questions alternate words may also be given in the bracket.
Example: In a dynamic energy is transformed into electric energy (Kinetic, potential, chemical, light)

Alternate Response type:
In this type of item, the examine has to choose the correct answer from among the two alternative answers. The same of each type are yes / no type, right/wrong type (V/x) mark type etc.
Example:
Please write ‘R’ for the correct statement and ‘W’ for incorrect statements in the box provided for the purpose.

  • Graphite is an amorphous carbon
  • The chemical formula of lime is CaO

Multiple Choice type:
This type is considered one of the best types. objective test items. Usually, four or more alternate answers called distracters are given under each question. The examine has to point out the most appropriate answer from among those alternatives.
Example – Which of the following is used in the extraction of iron?

  • Graphite
  • Diamond
  • coal
  • charcoal.

Correct the Error type :
In this type, the examinee has to correct the error if any in a statement
Example – Correct the error if any in the statement without changing the underlined portion. Jupiter is the nearest planet to the sun.

Classification type :
This is also called to find the odd man out type item.
Example:
Underline the item which does not fall under the groups. Iron, copper, rubber, aluminium, zinc

Matching type :
In this type of item, there are usually two columns, one acts as a stem and the other as an alternative. The number of items in the alternatives column should be more by two / three items them of the item to avoid the chance element.
Example – Join each word of column ‘ A’ with the appropriate word of column ‘B’

Column – A Column – B
Diamond Ammonium chloride
Alternate Current Dil. sulphuric acid Voltaic cell       Transformer
Edonita Armature
Dry cell Copper sulphate solution Non-conductor of electricity Dil. Hydrochloric acid

Analogy type :
In this type of test item, the examinee has to find out an analogous response having the same relationship as in the case of a known relationship.
Example: Fill in the blanks

  • C02 : CaC03 = H2:
  • Anophelis : Malaria _______ : Philaria :

Question 6.
Discuss the merits and limitations of objective-type tests?
Answer:
The merits of objective type test:
It can be scored objectively and easily. The scoring will not vary from time to time, from the examiner. In this test, examiner a more extensive and representative sampling can be obtained. This reduces the role of luck and cramming of expected questions. As a result, there is greater reliability and better content validity. It possesses an economy of time, for it takes less time to answer than the easy test, and comparatively, many test items can be presented to students.

It eliminates extraneous factors such as speed of writing, fluency of expression, literacy style good handwriting, neatness etc. It creates an incentive for pupils to build up a broad base of knowledge, skills and abilities. It measures the higher mental process of understanding, application, analysis, predictions and interpretation.

Limitation of objective type test:
Objectives like the ability to organize matter ability to present matter logically and in coherent fashions etc. cart not be evaluated. Guessing is possible. No doubt, the chances of success may be reduced by the inclusion of a large number of items. The construction of the adequate type of test items is difficult. It requires special abilities and is time-consuming. The printing cost is considerably greater than that of an essay-type test.

Question 7.
Discuss the advantages and limitations of short answer items (T/ F) items, matching tests and multiple-choice items?
Answer:
Short answer items – A short answer item is classified as a supply type/recall type objective item.
Example: Who succeeded Akabar?
Advantages:
A relatively large sample of content can be covered. It is easy to construct. It provides little opportunity for guessing. It is useful in evaluating the ability to interpret diagrams, charts and graphs. It is useful in evaluating spelling and knowledge of a foreign language. It is mathematics and science where a computational answer is required or where a formula or equation is to be written. Objectives understanding, application and problems during skill can be measured with short answer items.

Limitation:
It is less objective than the other type of objective item. It is almost impossible to write good short answer items that require a student to exhibit synthesis and interpretation so that one and only one answer will be correct. It is limited to questions that can be answered with a word, phrase, symbol or number. Its excessive use may encourage a student to memorise and develop poor study habits because short answer items are best for measuring highly specific facts like dress, names, places and vocabulary.

True / False items :
Here the student is presented with a declarative statement that is true or false.
Example:
T / F – The sun rises in the east T/F – Columbus discovered America.

Advantages of T/ F items:
They are good for young children who have poor reading habits. They can cover a large portion of the subject matter in a relatively short space and a short period of time. They provide high reliability per unit of testing time. They can be scored quickly, reliably and subjectively. They are adaptable to most content areas. They can be more easily constructed than other objective-type items.

They can be conveniently used to measure :
The ability to identify the correctness of the statement. The ability to distinguish fact from opinion and The ability to recognize the cause-and-effect relationship. It is carefully constructed they can measure the higher mental processes of understanding, application interpretation.

Limitations :
Pupils’ scores on T/F items can be unduly influenced by good or poor luck in guessing. They are more susceptible to ambiguity misinter pretation than any other selection type objective item and here therefore low reliability They lend themselves most easily to cheating.

They tend to be less discriminating Matching tests :
A matching test consists of two columns ‘A’ and ‘B Each item in column ‘A’ is to be paired with an alternative given in column ‘B Usually with the columns containing an unequal number of items.
Example:
Match the dates in column ‘B’ with the events in column ‘A’ by writing the number of items in ‘B’ in the space provided.

A B
1. India got her independence (i) 1525
2. Sepoy muting (ii) 1857
3. Odisha become an

independent province

(iii) 1936
4. First Battle of Panipat (iv) 1947
5. Death of Mahatma Gandhi. (v)1948
(vi) 1950

Advantages of Matching Test:
Because they require relatively little reading time, many questions can be asked in a limited period of testing time. They afford an opportunity to have a large sampling of the content, which ultimately increases the reliability of the test. The matching test can be Constructed relatively easily and quickly. The matching test gives less opportunity for guessing than, T/F items or M.C. items. Like T/F or MC items they are amenable to machine scoring.

Limitations:
If sufficient care is not taken in their preparation, they may encourage serial memorization rather than association. It is sometimes difficult to get clusters of questions that are sufficiently alive so that a common set of responses can be used. They cannot be very successfully used for measuring understanding of the ability to discriminate because of the difference in finding a homogenous response.

Multiple Choice Items :
Multiple choice test items have stems in form of a statement or a question and more than one option is provided. The examinee has to point out the correct answer.
Example: Stem which of the following men invented the telephone Responses or options,
(a) Marcone,
(b) Edison,
(c) Bell,
(d) Morse

Advantages of MC items:
They can measure learning outcomes with respect to factual recall, ability to apply to understand, ability to interpret the data ability to reason, ability to exercise judgement, ability to justify methods etc. They can be scored objectively, quickly, and accurately by machines, clerks and even students themselves. The degree of difficulty of the test can be contained by changing the degree of homogeneity of the responses.

They provide valuable diagnostic information especially if all the responses are plausible and vary only in their degree of correctness. They are easier to respond to and are better liked by the students than T/F items. They can be conveniently used for numerous subject matter areas.

Limitations:
They are very difficult to construct. More skill and more time are required. They are not well adapted for measuring the ability to organize and present ideas. They require more space for items.

(a) Long answer type
(b) Short answer type
(c) Objective tests

Different types of questions:
There are three kinds of questions as there are three kinds of written examination

Long answer type or Essay type questions:
This type of question requires some descriptions etc.
Example: Write what you do in children’s day.

Short answer type questions:
this type of question requires short answers. The child answers each question within two or three sentences. ;
Example:
Write an answer within two or three sentences – who was Nehru

Vocabulary tests :
Oral test:
In the oral test, the teacher assesses recording comprehension and expression.

Written test:
Objective type written test in English is designed to test the different linguistic abilities of the specimen of some questions are given below.

Comprehension type :
This type consists of a sentence or paragraph from which some words and phrases are omitted. The pupil is to fill in the blanks with suitable words or phrases. Correct use of prepositions and vocabulary can be tested with the type.

Fill in the blanks with the words from the box:

Question 14.
What are the general principles of teaching? Explain?
Answer:
There are some general principles which need to be followed by a teacher for successful teaching in the classroom. They are as follows:
Principles of motivation :
Motivation is the driving force behind all kinds of purposeful activities and most learning is the outcome of motivation. The learner has to be motivated to learn and to react to the stimulus whether it is an object or situation or information self-motivation is the best motivation. It is the duty of the teacher to arouse interest in the teacher before any teaching is done.

There are some natural angles in the child and sometimes the interest is also created or required. The teacher has to utilize natural urges as well as acquired interests for teaching different topics. Curiosity is another strong urge for motivation. If a child is curious to know how people in different parts of the world live it is natural on his part to read the relevant books and journals, listen to suitable radio programmes or view TV. Programmes, programmes dealing with the people of different lands.

Principle of Activity :
Learning by doing is the basic principle enunciated by Froebel who successfully implemented c. it in the kindergarten system. It is found that learning becomes more effective if the child is physically and mentally made active in the teaching-learning process. The head with the hand should work together for making learning easier and more interesting.

For example, for effective teaching about Odisha to different children, we can ask them to draw a map of the state, dramatic scenes from Odisha history and so on. All these activities must create interest as well as curiosity among children and enrich learning experiences about Odisha. Similarly, in science teaching the principle of learning by doing is very well applied and students are required to observe.

the garden, make experiments in the laboratories and the activity methods are followed by teachers not only at the primary stage but also at the higher stages of education. The project method, the problem-solving method, the Heuristic method and so on are all based on activities in and outside the classroom. Students’ participation and involvement in the teaching-learning process make their education.

more relevant and meaningful. The principles of learning by doing is not only adopted in teaching various curricular subjects but also applied in organizing co-curricular activities, the programmes like sports and games, debates and discussions drama and music fieldwork and excursion etc. emphasize such activities.

Principle Relating to life :
All educationists and psychologists insist that teaching should always be related to life and its problem. While teaching children of pre-primary and primary schools their environment home, village, community-related to learning experiences. Education has been accepted as a preparation for life, teaching should be related to life and students be prepared to face the challenge of life with success.

The educational institution should satisfy individual and social needs teaching is linked to life and the issues to be effective and useful. The education commission 1964-66 also emphasized that our education has to be related to the life needs and aspirations of the people.

Question 15.
Explain the maxims of methods of teaching?
Answer:
Various methods of teaching have been developed by educationists around the world b. through the ages for teaching students effectively.
But there are certain basic principles of teaching which are called the maxims of methodology and from the basis of the method of teaching. Adequate “knowledge of these maxims is essential for a teacher quality to perform his teaching activity with proficiency; They are as follows:

From the known to the unknown :
The most common way of teaching a lesson is to proceed from known to unknown. The pupils are taught end reminded about which they are already familiar and acquainted with them the facts and figures, which are not c. known but useful to them. They move from the familiar, concepts to the unknown and unfamiliar.

For example, to teach about warm deserts, we can draw a picture of the hot summer, with which they are acquainted. For teaching about freedom struggle, we can start with the Independence Day or Republic day celebration. Secondly, for teaching a lesson on profit and loss,- children may be reminded about their experiences in buying.

a certain thing and the Sale of goods in the local shops Thirdly in the teaching of new and difficult words in a language, the already known and familiar words with similar meanings can be recapitulated and made of it. Thus we proceed from known to unknown and from knowledge to experience.

From the simple to complex :
The topics to be taught are arranged according to the degree of complexity. In teaching a topic we divide various aspects or units of the topic according to the degree of simplicity so the teaching can be easier from the point of view of learning. The concepts which are simple to one may be complex to another so the experience of pupils is given importance while planning the teaching of a lesson. Topics are thus arranged according to the principle of proceeding from the simple to the complex.

From the concrete to the Abstract :
The abstract or vagueness of a topic poses a problem in understanding. Children find difficulty in understanding an abstract object or concept due to vagueness or lack of preciseness. For example, if we ask a pre-scholar to make a total of 2 and 3, he may find it different but if weask him to count 2 sticks after country 3 ones, then it may not be a problem.

Thus, manipulation with concrete things is easier than with abstract ones for children. In teaching a Geographical topic like Australia, the land and people, adequate use of maps, charts, models, and illustrations will be useful. Rather the use of radio and video programmes in Australia can make teaching more effective and interesting by going lively ideas and . experiences to the learner.

From the Indefinite to definite :
In the child’s mind, all concepts are indistinct, and unclear the interest and attitudes of children are also indefinite. But teaching aims at making all these ideas distinct and precise. In Indian schools, we emphasize blind memorization without understanding the meaning and implications which does not help in clarifying the concepts and removing the vagueness. We should give more emphasis on teaching concepts clearly and definitely. Teaching with the use of audio-visual aids should help on making the ideas distinct.

From the particular to the general :
Some students can easily comprehend particular of specific objects and ideas teaching should be started from the particular knowledge and proceed to give general knowledge which are comparatively vague and abstract in nature. The observing the specific objects, generalizations are drawn. In teaching various topics in arithmetic, sciences, geography and the like, this principle can be effectively applied in inducting method of teaching.

Induction followed by Deduction :
Induction is found more useful for teaching different subjects. In this method, teaching starts with particular examples then the conclusion is drawn. We accept a general principle or formula as valid which is then applied to individual or specific cases.1 This method is not proven sound and scientific for children’s learning. Both inductive and deductive methods have their advantage and can be used in teaching Suitable subjects.

For example, in teaching a new formula or a new theory the Inductive method can be used effectively. After teaching the formula of theory in the method it is easier to use the deductive method for teaching most of the exercises in arithmetic algebra and geometry and other subjects. So inductive teaching is always followed by deductive teaching.

Psychological vs logical :
The successful teacher teaches everything according to the psychological needs and conditions of pupils. But in the text-books topics are arranged logically. It is the duty of the teacher to arrange them Psychologically in the scheme of lessons as he is aware of the behaviours, needs, and interests of the students. Even in teaching a lesson a group’s teaching is to be done to their psychological needs and conditions. The remapping power is understood from the logical presentation. The teacher should apply the general principles and maxims in a psychological manner more effectively.

Question 16.
Discuss the relationship between teaching and learning. Discuss the factors affecting the teaching-learning process?
Answer:
Prior the 20th century, teaching is considered a rigid, formal and stereotyped process of transmitting knowledge, facts and figures. Education was taken as a Bipolar process in which teachers are giving and pupils are receiving end. Teachers are the source of knowledge and schools are knowledge shops. Methods of teaching are logical and routine without the psychological needs and conditions of learners, their interests, curiosity, freedom and flexibility emphasis was laid on rigid discipline blind memorization and hard reinforcement.

Verbalism was enforced and no audio-visual aids or materials were utilized in the field of education. The learner is considered an empty vessel to be filled up with knowledge and information, facts and figures. But in the 20th century, the child is considered a tender plant and a teacher as a gardener. The child is taught according to his abilities, attitude interests and aptitude.

He is helped to learn to teach nourish, and cultivate the growing child and guide his growth. Children are motivated to search experiments, gathering facts and information. Various media and materials are used for making learning more interesting and effective. Now, learning has assumed more importance than teaching.

There has been a change in the learning process. New theories of learning highlight the principles of contiguity and the importance of the environment etc. Multimedia systems and educational technology.  Now, stress is given in the principle of learning, than traditional teaching. There are three types of effectiveness in teaching such as pre-stage effectiveness, process effectiveness and product effectiveness.

The quality of learning depends on the quality of teaching. The end result of the teaching process determines the product’s effectiveness. The important teaching results in the outcome of learning. It is evaluated through achievement tests, and personality tests administrated to students. The input of teaching is results in the outcome of learning.
