Stages of Human Development: NBSE Class 12 Education answers

Summary

Human life is a journey of constant change, from being a baby to an adult and then an old person. While growth is a continuous process, we can look at it in different stages to understand it better. The main periods are before birth and after birth. The time after birth includes infancy, childhood, adolescence, and adulthood.

Infancy is the first stage, from birth to about two years. An infant depends completely on others for care. This is a time of very fast physical growth in height and weight. Their bones are soft, and their first teeth appear. Infants learn about the world using their senses. Socially, they start by focusing on their own needs but soon learn to recognize family and smile. They express emotions like joy, fear, and anger. This period is called the ‘foundation age’ because it builds a base for future behaviors.

Childhood follows, from about age three to twelve. Physical growth is slower but steady. Children become stronger, and their brains develop a lot. They are very curious and ask many questions, so this is called the ‘questioning age’. They learn to share and cooperate with friends. They often form groups, which is why it is also known as the ‘gang age’. Emotionally, children gain more control over their feelings and develop ideas about right and wrong.

Adolescence connects childhood to adulthood, from about age twelve to nineteen. This stage has intense and rapid changes. The body grows into its final adult form, and boys and girls develop distinct physical traits. Feelings can be very strong and change quickly. Adolescents think deeply about who they are, which is a ‘search for identity’. They want more independence and may question rules. Friendships become very important. Their ability to think about complex ideas also grows.

Understanding these stages helps adults provide the right support. During infancy, learning happens through play and the senses. In childhood, it is good to encourage curiosity and learning through activities. For adolescents, guidance and understanding are needed. They benefit from positive outlets for their energy, like sports, art, or helping others. Meeting the needs of each stage helps a person grow into a balanced adult.

2. What are the three stages of human development?

Answer: The three main stages of human development which are infancy, childhood, and adolescence.

3. Describe the physical, emotional, and social developmental characteristics of infancy.

Answer: The physical, emotional, and social developmental characteristics of infancy are as follows:

Physical Development:

Height: An average Indian child at birth measures between 17 to 21 inches. At one year, the child is 28 to 30 inches, and at two years, the child is 32 to 34 inches tall, which is almost double the birth length.
Weight: An average Indian newborn weighs 2.5 to 3.25 kg. A newborn normally loses some weight but regains it by 7-10 days. At the age of four months, the baby doubles his or her birth weight, and at the end of the first year, triples it.
Development of Bones: Ossification, or the hardening of bones, mainly takes place during infancy. The bones of babies are soft and can be easily deformed.
Development of Teeth: Teeth begin to appear when the baby is 5 to 6 months old. They usually come out at a rate of about one tooth a month. Out of 20 temporary teeth, about 16 appear by the age of 2 years.
Development in the Nervous System and Eye Muscles: Growth in the nervous system consists mainly of the development of immature cells present at birth. Eye muscles are well coordinated and can distinguish colours.

Social Development:

The infant is not social at birth and is very self-centered, only concerned with satisfying physical needs.
During the 1st month, the infant cannot differentiate between human voices and other noises.
During the 2nd month, the infant recognises the sounds of human beings and smiles at people.
During the 3rd month, the infant recognises his or her mother and feels unhappy when separated.
During the 4th month, the infant shows selective attention to the human face and feels happy in their company.
During the 5th month, the infant reacts differently to smiling and scolding and can distinguish between friendly and angry voices.
During the 6th month, the infant recognises familiar persons with a smile and shows a definite expression of fear towards strangers.
During the 8th and 9th months, the infant attempts to imitate speech, simple acts, and gestures.
Between the 10th and 12th months, the infant plays with his or her own image.
At the 12th month, the infant becomes an active member of the family.
From the 13th to 18th month, the infant’s interest shifts from play materials to playmates.
Between 20-24 months, the infant cooperates in routine activities like being dressed, fed, and bathed.

Emotional Development: In the beginning of life, emotions are not clear, but as the child grows, different emotions become clearer and can be easily interpreted.

Anger: When interfered with, unable to do a task, or not being understood, the child reacts by screaming, kicking, and waving the arms.
Fear: Any stimulus that occurs suddenly, unexpectedly, or is different from what the infant is used to, causes fear.
Curiosity: Anything new or unusual acts as a stimulus for curiosity, which is expressed mainly through facial expressions.
Joy: This is stimulated by physical well-being and friendly responses from others. It is expressed through smiling, laughing, baby coos, and gurgles.
Affection: Family members, toys, and pets stimulate the infant’s affection, which is expressed by hugging, patting, and kissing.

4. List the general notions of infancy stage of human development.

Answer: The general notions of the infancy stage of human development are:

Age of dependence: The infant is totally dependent on the caretaker to fulfill all its needs.
Age of rapid growth and change: Growth is both physical and psychological. The bodily movements are more coordinated and the infant is able to recognise and identify people and objects.
The foundation age: At this period of time, the foundation of many behaviours, patterns, attitude to others, and self and emotional expressions are being established.
A shy age: The infant’s world is limited to the family and to some significant people. It shies away from strangers and unfamiliar surroundings.
A hazardous age: The child is prone to physical illnesses and accidents. The high infant mortality rate is evidence of this.
An appealing age: Adults as well as older children find the infant appealing because of its helplessness, dependency, and easy to manage feeling that one gets.

Long Answer Questions

1. Trace those events from your own childhood and adolescent stages that reflect the characteristics of these periods.

Answer: Looking back, I can see how my own life reflects the characteristics of childhood and adolescence described.

During my childhood, I remember the world being a place of exploration. I was part of a close-knit ‘peer group’ in my neighbourhood, which we considered our ‘gang’. We had our own rules and a strong sense of group loyalty. This was the ‘gang age’. I was also very curious and would ask my parents an endless stream of questions about everything, which shows it was a ‘questioning age’. Socially, I learned behaviours like cooperation and sharing while playing with my friends, but I also remember being selfish with my favourite toys at times.

Adolescence was a period of intense change. I recall feeling moody and having fluctuating emotions; I could be very happy one moment and sad the next for no clear reason. There was a strong desire for independence, and I often felt a need to rebel against the authority of my parents and teachers, replacing my earlier obedience with a spirit of criticism. I became very interested in the ways of adult living. My friendships became deeper and were based on common interests and hobbies, and these friends are still very important to me. I spent a lot of time thinking about who I was and what my role in society would be, which was my search for ‘identity’. This period was also a time of great intellectual awakening, where my curiosity was at its height, and I developed a strong urge for self-expression through writing and participating in debates.

2. How can a teacher help adolescents develop a balanced personality? Discuss your experiences in this regard.

Answer: A teacher can help adolescents develop a balanced personality in several ways. The fundamental task of education is to help adolescents progress towards physical, sexual, mental, and emotional maturity, which is the ‘fullest development’ of personality. To achieve this, the first essential thing for teachers is to develop a warm and genuine interest in them. Acceptance of emotionally disturbed students by their teachers is the basic principle which they must start with, as this helps students to understand and deal with their problems and provides the emotional security they need.

Other ways a teacher can help include:

Introducing adolescents to suitable literature to help them satisfy their needs for adventure, love, and affection.
Providing sex education in a plain, straightforward manner to satisfy their curiosity.
Providing hard physical activities to exercise their fully developed physique and relieve sex pressure.
Directing their hero-worship attitude towards desirable qualities by presenting heroes from real life, history, or literature, which may lead them towards the formation of an “Ideal-self”.
Keeping the individual occupied in various games, co-curricular activities, and debates to avoid self-consciousness and daydreaming.
Providing proper vocational guidance to help them select a future career.
Ensuring their emotional life is well-balanced by curtailing activities that cause frustrations, disappointments, conflicts, and stresses.
Providing an abundance of interesting material, manual work, plenty of outdoor exercise, games, regular sleep, and hygienic food arrangements.

During my own adolescence, I remember feeling very confused and anxious. A single sentence of a sympathetic teacher, who noticed I was struggling and told me it was okay to feel that way, restored my self-confidence. This was more helpful than any formal counselling could have been. That teacher also encouraged me to join the debate club, which helped me channel my energy positively and kept me occupied, preventing me from daydreaming. This experience showed me how a teacher’s acceptance and guidance can bridge the gap and provide the emotional security an adolescent needs.

3. Describe the physical, emotional, and social developmental characteristics of early and late childhood.

Answer: The developmental characteristics of early and late childhood are as follows:

Early Childhood (From 3 to 6 years)

Physical Development: This stage is characterised by slow, steady, and uniform growth. By five years, the child’s height approximately becomes almost double their birth height, and they acquire almost five times their birth weight. The arms and legs lengthen, the trunk elongates and becomes slimmer, and the abdomen flattens. The nervous system shows rapid growth during the first four years, and by the age of four, the brain gains almost 80% of its final weight. Near the end of the fifth year, the permanent teeth begin to appear.
Social Development: Social behaviours like imitation, co-operation, sympathy, and sharing are common. However, unsocial patterns like negativism, aggressiveness, selfishness, and egocentrism also develop. The child desires freedom and takes satisfaction in doing work with their own efforts.
Emotional Development: This is a period of stability and control. The child learns to hide his/her feelings and expresses emotions in an appropriate and socially approved manner.

Late Childhood (From 7 to 12 years)

Physical Development: Growth continues to be slow and steady. The bones continue to ossify at different rates in different parts of the body. The muscles become larger, stronger, and heavier.
Social Development: The child becomes an active member of the ‘peer group’, and this stage is referred to as the ‘gang age’. They believe in group loyalty and try to conform to the rules and values of the group. A sort of segregation is found among boys and girls, as they form their own groups among members of their own sex. The interests and values of the peer group often have a clash with the interests and values of teachers and parents.
Emotional Development: In this stage, the child’s emotional behaviour gets structured into sentiments. Various sentiments like religious, moral, patriotic, and aesthetic sentiments begin to develop, which leads towards character formation.
Intellectual Development: The power of memory increases. At 7 years, a child tries to distinguish between two objects. At 8 years, a child is able to repeat sentences containing 16 to 17 words. At 9 years, a child becomes conscious of day, time, and date, and recognises coins of various denominations. At 10 years, a child points out mistakes in short sentences and repeats 60–70 words in three minutes. At 11 years, a child can recognise similarity and differences and make comparisons. At 12 years, a child points out the cause of a thing and provides his own explanation.

4. Tabulate the various differences between infancy and adolescent stages of human development.

Answer:

Basis of Difference	Infancy (Birth to 2 years)	Adolescence (12 to 19 years)
Physical Development	A period of very rapid growth. Height almost doubles by two years, and weight triples in the first year. Ossification of soft bones begins, and temporary teeth appear.	Physical growth reaches its peak, and the body finds its final shape. Maximum height and weight are achieved. Sexual maturity is attained, and secondary sexual characteristics develop.
Social Development	The infant is not social at birth and is self-centered. Social response is directed towards family members. The infant is dependent on adults for all needs.	This is a period of social maturity. There is a strong spirit of independence and rebellion against authority. Friendships are based on common interests and are very important. The individual is in search of ‘identity’.
Emotional Development	Emotions are not clear at first and develop from general excitement to specific feelings like delight, distress, fear, and anger.	Emotions are violent, intensive, and fluctuating, making the individual moody, tense, and anxious. Sentiments like self-respect, personal pride, and group loyalty are strong.
Intellectual Development	This is the ‘Sensorimotor Stage’. Learning occurs through sensory exploration like looking, listening, and testing. The infant begins to develop basic concepts of space, weight, and self.	There is a great intellectual awakening. The individual engages in complex and abstract thought. Curiosity is at its height, and special aptitudes may develop. There is a strong urge for self-expression.
Dependency	The infant is totally dependent on the caretaker to fulfill all needs.	The adolescent strives for independence from adults and wants to be free from all adult restraints.

5. Describe the physical, intellectual, and social developmental characteristics of adolescent stage of human development.

Answer: The physical, intellectual, and social developmental characteristics of the adolescent stage are as follows:

Physical Development

The physical growth and development reaches its peak and the human body finds its final shape.
The maximum limit with regard to increase in size, weight, and height is achieved.
Bones and muscles increase to the greatest possible extent, leading to a great increase of motor activity.
Growth of all other inner and outer organs reaches its maximum and almost all the glands become extremely active at this stage.
There is growth of hair under the arms and the genital organs.
Boys and girls develop the characteristic features of their respective sexes. For girls, there is the roundness of breasts and hip, their voice acquires shrillness, and they begin to menstruate. For boys, a beard and moustaches grow, their voice deepens, and they have nocturnal emission.
Sexual development reaches its peak. The development undergoes three stages: Stage of Auto-erotism or Self-love, Stage of Homo-sexuality, and Stage of Heterosexuality.

Social Development

This is a period of social maturity.
A spirit of independence is manifested in interest. Self-assertion is strong and wants to be free from all adult restraints.
There is a marked tendency to rebel against authority.
They are more interested in the ways of adult living and are anxious to be initiated into it.
Habitual obedience to parents and elders is replaced by a spirit of criticism and revolt.
They are very much attached to their families and the feeling of family loyalty is very strong.
Friendships of adolescents are based on their common interests, hobbies, and skills and subsequently tend to last longer than friendships in early childhood.
They want recognition and attention from others. They are in search of ‘identity’ and seek to clarify who they are and their role in society.
Adolescents are highly sensitive, idealists, and social reformers by nature.

Intellectual Development

There is great intellectual awakening, and curiosity is at its height.
Adolescents engage in a larger and more complex range of activities.
The adolescent may develop a special aptitude for music or language, may begin composing poems, and begins to appreciate literature.
His/her vocabulary widens and they enjoy debates, discussions, and dramas.
The urge for self-expression is very great, which may result in writing, acting, or painting.
The adolescent has a desire for responsibility but also has a tendency to be irresponsible.
He/she is impatient for the results and is very enthusiastic.

6. Explain the educational significance of all three stages of human development.

Answer: The educational significance of infancy, childhood, and adolescence is as follows:

Nature of Education in Infancy: The education of the infant mostly consists of the training of higher senses, and the apparatus of education has to consist of concrete materials, as in the Montessori Method. The process of education should involve activities and concrete experiences. Education must provide for the satisfaction of the infant’s instinct of submission, self-satisfaction, and fantasy. The teacher must ensure the infant’s emotional needs are fully satisfied. School activities should be based on the pleasure-principle, meaning activities in which the child is mostly interested, and the Play-way method may be applied. The child’s experience should be enriched by taking them outdoors to places like fields, parks, and zoos to have knowledge of the world.

Nature of Education in Childhood: Childhood is the time when an individual’s basic values and ideals are shaped. Behaviour should be voluntary and guided, not dominated by force. The teacher must provide varied occupations, as the child is deeply interested in outdoor activities. The child should be given scope for questioning, and their curiosity must be satisfied by giving factual information. Learning at this stage should be based on the proper arousal of curiosity. The child should be provided opportunities to exercise their constructive instincts, and ‘Learning through doing’ should be used. Methods like the Project method, Heuristic method, Storytelling, and Dramatisation exert a strong influence. The school should also have provisions for fine arts, games, outdoor activities, and social and community activities. Discipline should be self-governed rather than done by restriction.

Nature of Education in Adolescence: The fundamental task of education is to help adolescents progress towards physical, sexual, mental, and emotional maturity, which is understood as the ‘fullest development’ of personality. To solve their problems, teachers must develop a warm and genuine interest in them and accept emotionally disturbed students to provide them with emotional security. Teachers can introduce them to suitable literature to satisfy their needs for adventure, love, and affection. Sex education should be given in a plain, straightforward manner. The adolescent must be provided with hard physical activities and a curriculum with enough material to satisfy their thirst for knowledge. A teacher can direct their hero-worship attitude towards desirable qualities to help form an “Ideal-self”. Proper vocational guidance should be given, and their emotional life should be well-balanced by keeping them occupied in games and co-curricular activities.

32. Define the Stage of Auto-erotism or Self-love.

Answer: The Stage of Auto-erotism or Self-love is when the adolescent loves his/her body and stands before the mirror for a long time. If he/she has feelings of inadequacy and emotional deprivation, he/she indulges in masturbation, which is the self-stimulation of the genitals as a means of sexual satisfaction.

33. What is the Stage of Homo-sexuality in adolescence?

Answer: The Stage of Homo-sexuality is when boys and girls are attracted toward the members of their own sex and seek gratification from each other’s body by grouping them in two or three at one time. Most often this stage passes on to the next stage, heterosexuality.

34. What is the Stage of Heterosexuality in adolescence?

Answer: The Stage of Heterosexuality is when boys and girls are seen attracted towards each other.

Each stage has certain characteristic features and prepares the ground for the next stage.

36. What factors influence the age range of development stages across cultures?

Answer: The exact age range of development stages is arbitrary and depends on cultural factors. The range of adolescence, for instance, not only differs from country to country but also varies from community to community and from individual to individual. Some of the factors which control the dawn of puberty and attainment of maturity include the standard of living, early or late marriage, health and climate, cultural traditions and environment, attitude towards sex, and the role expected from the child at different ages.

37. What is the modern understanding of a newborn baby’s capabilities?

Answer: The modern understanding is that the newborn baby, or neonate, enters the world with surprisingly sophisticated perceptual and motor abilities, a set of skills for interacting with people, and a capacity to learn that is put to use immediately after birth. The previous view of the infant as a passive, incompetent being has been shown to be wrong. It is now well accepted that infants, from the outset, are skilled and capable beings who display the beginnings of many complex abilities.

38. What are the general notions of infancy as the “foundation age” and “shy age”?

Answer: The notion of infancy as “the foundation age” means that at this period of time, the foundation of many behaviours, patterns, attitudes to others, and self and emotional expressions are being established.

The notion of infancy as “a shy age” means that the infant’s world is limited to the family and to some significant people. The infant shies away from strangers and unfamiliar surroundings.

39. Describe the physical development of an infant in terms of height and weight.

Answer: In terms of height, an average Indian child at birth measures between 17 to 21 inches. At one year, the child is 28 to 30 inches, and at two years, the child is 32 to 34 inches tall, which is almost double their birth length.

Regarding weight, an average Indian newborn weighs 2.5 to 3.25 kg. A newborn normally loses some weight but regains it and shows an increase within 7-10 days. An infant doubles their birth weight at four months and triples it by the end of the first year.

40. Why is it advisable to change a baby’s sleeping position frequently?

Answer: It is advisable to change a baby’s sleeping position frequently because the bones of babies can be easily deformed as they are soft. Ossification, or the hardening of bones, mainly takes place during infancy. The shape of the head can be flattened if a baby spends most of its sleep time on its back, and the chest can be flattened if the baby sleeps too long on its stomach. Therefore, it is advisable to change the baby’s position every two to three hours.

41. Describe the social development of an infant during the first two months.

Answer: The infant is not social at birth and is very self-centered, only concerned with the satisfaction of his/her physical needs. During the first month, the infant cannot differentiate between human voices and other noises. A social development milestone occurs during the second month, when the infant begins to recognise the sounds of human beings and gives smiles to the person.

42. What social milestones occur in an infant between the 3rd and 6th months?

Answer: Several social milestones occur between the 3rd and 6th months.

During the 3rd month, an infant recognises his/her mother and feels unhappy on separation.
During the 4th month, he/she shows selective attention to the human face and feels happy in their company.
During the 5th month, he/she reacts differently to smiling and scolding and can distinguish between friendly and angry voices.
During the 6th month, he/she recognises familiar persons with a smile and shows a definite expression of fear for strangers.

43. What is the ‘Sensorimotor Stage’ according to Piaget? How does an infant learn?

Answer: According to Piaget, the ‘Sensorimotor Stage’ is a stage in conceptual development where an infant’s earliest perceptions come through sensory exploration. An infant learns by:

Looking, listening, smelling, and testing anything that comes its way.
Trying to discover meaning through simpler forms by asking the questions ‘who’, ‘what’, ‘why’.
Associating ideas with objects and situations, which results in the development of concepts of space, weight, time, self, social, beauty, and comic.

44. Describe the main characteristics of physical development during childhood.

Answer: The stage of childhood is characterised as the period of slow, steady, and uniform growth, with a very slow development rate. By five years, the child’s height approximately becomes almost double, and he/she acquires almost five times his birth weight. The arms and legs lengthen and may become spindly, and the hands and feet grow bigger. The trunk elongates and becomes slimmer, the neck becomes longer, the chest broadens, and the abdomen flattens. The muscles also become larger, stronger, and heavier, with the result that children look thinner.

45. How does a child’s body proportion change during the childhood stage?

Answer: The stage of childhood is characterised as the period of slow, steady, and uniform growth. During this time, the arms and legs lengthen and may become spindly, and the hands and feet grow bigger. The trunk elongates and becomes slimmer, the neck becomes longer, the chest broadens, and the abdomen flattens. The muscles also become larger, stronger, and heavier, which results in children looking thinner.

46. What is the ‘latency period’? Why is it called so?

Answer: During the physical development of childhood, the stage is sexually known as the ‘latency period’. This term is used because the sexual energy of the child lies dormant throughout this stage. However, this dormant energy is significant because it is expected to emerge with great force at the end of the childhood stage, marking the transition to the next phase of development.

47. Why is childhood referred to as the ‘gang age’?

Answer: Childhood is referred to as the ‘gang age’ because the child shows more interest in outside activities with the peer group than with parents and family members. During this time, he or she becomes an active member of this ‘peer group’. The child also believes in group loyalty and therefore tries to conform to the rules and values that are maintained by the group to which he or she belongs.

48. How does emotional development show stability and control during childhood?

Answer: During childhood, emotional development shows significant stability and control. The child learns to hide feelings and express emotions in an appropriate, socially approved manner. This emotional behaviour is not guided by instinctive causes but has an appropriate rationale behind it. In this stage, emotions also get structured into various sentiments, such as religious, moral, and patriotic ones, which leads towards character formation.

49. Why is childhood called a ‘questioning age’ or an ‘exploratory age’?

Answer: Childhood is called a ‘questioning age’ or an ‘exploratory age’ due to the progressive changes in the child’s mental process. During this time, the child seeks to satisfy his or her voracious curiosity by asking an infinite variety of questions to parents and others. This constant questioning is a key part of their intellectual development, which includes developing concepts, perception, language, and reasoning.

50. What factors control the onset of puberty and maturity in children?

Answer: The standard of living, early or late marriage, health and climate, cultural traditions and environment, attitude towards sex, and the role expected from the child at different ages are some of the factors which control the dawn of puberty and attainment of maturity by children.

51. Describe the physical changes that occur in girls during adolescence.

Answer: During adolescence, girls develop the characteristic features of their sex. This includes the roundness of breasts and hips. Their voice acquires shrillness and becomes sweet, and they begin to menstruate monthly during this period. In general, girls become sexually as well as socially mature at an early age, with the adolescence period in India usually ranging from 11 to 17 years for them.

52. Describe the physical changes that occur in boys during adolescence.

Answer: During adolescence, boys develop the characteristic features of their sex. A beard and moustaches grow among boys, and their voice deepens and becomes harsher. They also experience nocturnal emission, which is the discharge of semen during sleep and is often accompanied by erotic dreams. The period of adolescence for boys in India usually ranges from 13 to 19 years.

53. What is meant by sexual hypocrisy in adolescents? How is it expressed?

Answer: Sexual hypocrisy is a characteristic seen in adolescents during their social development. It means showing an apparent indifference towards the members of the opposite sex, while at the same time trying to win their attention. This behaviour occurs even though both boys and girls appreciate each other at this stage. It is a complex social behaviour that marks this period of development.

54. Why do adolescents tend to rebel against authority and criticize elders?

Answer: Adolescents tend to rebel against authority and criticize elders because their spirit of independence and self-assertion is strong, and they want to be free from all adult restraints. For this reason, habitual obedience to parents and elders is replaced by a spirit of criticism and revolt.

55. List some common social interests of adolescents in their daily lives.

Answer: General, common social interests of adolescents in daily life are:

Enjoying parties.
Conversations in get-togethers. They talk about things that interest or disturb them from which they derive a sense of security.
Helping others when misunderstood, mistreated or oppressed. Group loyalty becomes very much pronounced.
Interests in world affairs, government and politics, through reading and discussions with peers, teachers and parents. Cooperation reaches its peak.
Criticism and reform: Often destructive in criticism and usually impractical in ‘reformatory’ suggestions.
Taking alcohol or drugs, smoking or playing cards in forbidden areas is also common.
The occupational choices have a big role in the social development, as they want to be self-dependent. Accordingly they have the choice of their social circle.

56. Why are adolescents often described as moody and inconsistent in their emotions?

Answer: Adolescents are not consistent in their emotions. They have very fluctuating emotions, which are frequent and quick. This makes them moody. Sometimes they are very happy and at other times they are extremely sad, and this happens in a very short span of time.

57. How does the need for education differ for an infant?

Answer: The education of the infant mostly consists of the training of higher senses, and the apparatus of education has to consist of concrete materials, as in the Montessori Method. The process of education has to consist of activities and concrete experiences. An infant’s education must provide for the satisfaction of the instinct of submission and self-satisfaction, as well as their fantasy. The teacher must ensure the infant’s emotional needs are fully satisfied. School activities should be based on the pleasure-principle, meaning activities in which the infant is mostly interested, and the play-way method may be applied.

58. What is the nature of education suitable for the childhood stage?

Answer: During childhood, education should guide a child’s voluntary behaviour rather than using force. The teacher must provide varied occupations, especially outdoor activities like running, climbing, and swimming. The child should be given scope for questioning, and their curiosity must be satisfied with factual information. Learning should be based on arousing curiosity and learning through doing. Methods like the Project method, Heuristic method, Storytelling, and Dramatisation are influential. Discipline should be self-governed, not based on restriction, and there should be provisions for games, social, and community activities.

59. Why is sex education considered an urgent need during adolescence?

Answer: Sex education is considered an urgent need during adolescence because the sex instinct is very intense at this stage. To satisfy the curiosity for sex, different types of creative activity can be a better method of channelising the sex drives of the adolescent. Sex education should be given in plain, straightforward talk, not in hints. Increasing knowledge enables the adolescent to relate their different tendencies in harmony with each other.

60. How can a teacher help adolescents deal with self-consciousness and daydreaming?

Answer: To help adolescents deal with self-consciousness and daydreaming, a teacher should keep the individual occupied in various games, co-curricular activities, debates, and other such activities.

61. Explain the key ideas presented in the introduction about human development.

Answer: One of the most important features of all living beings is change, which is most striking in the human life span from conception to death. Several changes happen each day in our bodies and psychological functioning; some are noticeable while others are not. Some of these changes are determined more by hereditary or genetic factors, while some depend more on environmental and cultural factors. Even though development is a continuous process, some theorists believe that various stages can be identified to locate major shifts and determine developmental tasks, which helps in monitoring the pace of developmental changes. It must be pointed out that there is no sharp dividing line between these stages. Each stage has certain characteristic features and prepares the ground for the next stage. The entire life span of an individual is divided into various stages, and all individuals have to pass through them.

62. Describe the different definitions of infancy from medical, legal, and psychological perspectives.

Answer: The stage of infancy is defined differently from various perspectives.

Medically, an infant is referred to as a person who is incapable of speech and is thus helpless.
Legally, a person is regarded as an infant until he or she reaches the age of eighteen. A minor, according to the law, is thus an infant.
Psychologically, the first two years of life are referred to as infancy. Elizabeth B. Hurlock spanned infancy from birth till two weeks and attributed the term babyhood to the period from the end of the second week after birth until the end of the second year of life. In general, infancy refers to the period of development that begins at birth and ends about 18 months to 2 years of age with early language use.

63. Explain the general notions of infancy, covering at least four key aspects.

Answer: There are several general notions associated with the stage of infancy. These include:

Age of dependence: The infant is totally dependent on the caretaker to fulfill all its needs.
Age of rapid growth and change: Growth is both physical and psychological. The bodily movements become more coordinated, and the infant is able to recognise and identify people and objects.
The foundation age: During this period, the foundation of many behaviours, patterns, attitudes to others, and self and emotional expressions are established.
A shy age: The infant’s world is limited to the family and to some significant people. It shies away from strangers and unfamiliar surroundings.
A hazardous age: The child is prone to physical illnesses and accidents, and the high infant mortality rate is evidence of this.
An appealing age: Adults and older children find the infant appealing because of its helplessness, dependency, and the easy-to-manage feeling one gets.

64. Describe the physical development in infancy. Include details on bones, teeth, and the nervous system.

Answer: During the first year of life, a baby goes through more changes in body size than at any other time. An average Indian child at birth measures between 17 to 21 inches and by two years is 32 to 34 inches tall. An average newborn weighs 2.5 to 3.25 kg, doubles this weight by four months, and triples it by the end of the first year.

Bone development involves growth in size and changes in composition. Ossification, or the hardening of bones, mainly takes place during infancy. The bones are soft and can be easily deformed.

Teeth start developing in the jaws during the third or fourth month of pre-natal life but appear around 5 to 6 months of age. Out of 20 temporary teeth, about 16 appear by the age of 2 years.

Growth in the nervous system consists primarily of the development of immature cells present at birth rather than the formation of new cells. Eye muscles are well coordinated and can distinguish colours.

65. Detail the progression of social development in an infant from birth to 24 months.

Answer: An infant is not social at birth and is very self-centered. The progression of social development is as follows:

During the 1st month, the infant cannot differentiate between human voices and other noises.
During the 2nd month, the infant recognises the sounds of human beings and gives smiles to the person.
During the 3rd month, the infant recognises his or her mother and feels unhappy on separation.
During the 4th month, the infant shows selective attention to the human face.
During the 5th month, the infant reacts differently to smiling and scolding.
During the 6th month, the infant recognises familiar persons with a smile and shows fear of strangers.
During the 8th and 9th months, the infant attempts to imitate speech and gestures.
Between the 10th and 12th months, the infant plays with his or her image.
From the 13th to 18th month, interest shifts from play materials to playmates.
Between 20-24 months, the infant cooperates in routine activities like being dressed, fed, and bathed.

66. What are the main emotional characteristics of infancy? Explain anger, fear, and joy.

Answer: In the beginning of life, emotions are not clear, but as the child grows, different emotions become clearer and can be easily interpreted. The main emotional characteristics of infancy include anger, fear, and joy.

Anger: When interfered with its movements, unable to do a task, or not being understood, the child reacts by screaming, kicking, waving the arms, and jumping up and down.
Fear: Any stimulus which occurs suddenly or unexpectedly or which is different from what the infant is accustomed to gives rise to fear.
Joy: Joy is stimulated by physical well-being and friendly responses to others. It is expressed through smiling, laughing, baby coos, gurgles, or even shouts with glee, and all bodily movements are intensified.

67. Trace the development of different emotions from birth to 24 months as shown in the table.

Answer: The development of emotions from birth to 24 months progresses as follows:

At birth: Excitement
3 months: Excitement, distress and delight
6 months: Excitement, distress, delight, fear and anger
12 months: Excitement, distress, delight, fear and anger, elation and affection
18 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy
24 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy, and joy

68. Describe the key features of physical development during the stage of childhood.

Answer: The stage of childhood is characterised as a period of slow, steady, and uniform growth. By five years, the child’s height approximately doubles, and they acquire almost five times their birth weight. The arms and legs lengthen and may become spindly, while the hands and feet grow bigger. The trunk elongates and becomes slimmer, the neck becomes longer, the chest broadens, and the abdomen flattens. By the age of four, the brain gains almost 80% of its final weight. The bones ossify at different rates, and near the end of the fifth year, permanent teeth begin to appear. The muscles become larger, stronger, and heavier, which results in children looking thinner. Sexually, this stage is the ‘latency period’, where sexual energy lies dormant.

69. Explain the characteristics of social development during childhood, including unsocial patterns.

Answer: During childhood, social behaviours like imitation, co-operation, sympathy, empathy, social approval, sharing, and attachment to people outside the home are common. However, unsocial patterns like negativism, aggressiveness, ascendant behaviour, selfishness, egocentrism, destructiveness, prejudices, and sex antagonism also develop. At this stage, the child desires freedom and takes satisfaction in doing work with their own efforts. They show more interest in outside activities with their peer group than with family members. The child becomes an active member of a ‘peer group’, and this stage is referred to as the ‘gang age’. They believe in group loyalty, conform to its rules, and a sort of segregation is found among boys and girls, who form their own groups with members of their own sex.

70. What are the main features of emotional and intellectual development in childhood?

Answer: Emotional development in childhood is a period of stability and control. The child learns to hide feelings and express emotions in an appropriate and socially approved manner. Emotional behaviour is not guided by instinctive causes but has an appropriate rationale behind it. This stage can also give birth to complexes due to inhibition and repression. The child’s emotional behaviour gets structured into sentiments like religious, moral, patriotic, and aesthetic sentiments, which leads towards character formation.

Intellectual development involves progressive changes in mental processes. Mental growth continues in childhood, and the child seeks to satisfy a voracious curiosity by asking many questions, which is why this is called a questioning or exploratory age. The child’s interests grow in number and extent, including interests in reading short stories and history. The power of memory increases. At 6 years, a child can distinguish between right and left, and by 9 years, becomes conscious of day, time, and date. By 10 years, a child can point out mistakes in short sentences.

71. Why is the period of adolescence not rigid? What factors cause variations in its range?

Answer: The range for the period of adolescence is not rigid because achieving puberty and becoming mature cannot be tied to a universal span or period. It is very difficult to point out the exact range of the adolescence period in terms of chronological years. Therefore, the range of adolescence not only differs from country to country but varies from community to community and from individual to individual.

The factors which control the dawn of puberty and attainment of maturity by children include the standard of living, early or late marriage, health and climate, cultural traditions and environment, attitude towards sex, and the role expected from the child at different ages.

72. Explain the physical development that occurs during adolescence for both boys and girls.

Answer: During adolescence, physical growth and development reach their peak, and the human body finds its final shape. The maximum limit with regard to increase in size, weight, and height is achieved. Bones and muscles increase to the greatest possible extent, leading to a great increase in motor activity. The growth of all other inner and outer organs reaches its maximum, and almost all the glands become extremely active. There is also growth of hair under the arms and the genital organs.

Boys and girls develop the characteristic features of their respective sexes:

Girls: There is the roundness of breasts and hip among the girls. Their voice acquires shrillness and becomes sweet, and they begin to menstruate monthly during this period.
Boys: Beard and moustaches grow among boys. Their voice deepens and becomes harsher, and they have nocturnal emission (discharge of semen during sleep) accompanied by erotic dreams.

73. What are the three stages of sexual development during adolescence? Explain each stage.

Answer: During adolescence, the sexual development undergoes three stages of change.

The first is the Stage of Auto-erotism or Self-love. In this stage, the adolescent loves his/her body and stands before the mirror for a long time. If he/she has feelings of inadequacy and emotional deprivation, he/she indulges in masturbation, which is self-stimulation of the genitals, as a means of sexual satisfaction. This is not a symptom of emotional abnormality, and there is absolutely no need for anxiety.
The second is the Stage of Homo-sexuality. At this stage, boys and girls are attracted toward the members of their own sex and seek gratification from each other’s body by grouping them in two or three at one time. Most often this stage passes on to the next stage, heterosexuality.
The third is the Stage of Heterosexuality. At this stage, boys and girls are seen attracted towards each other.

74. What are the main characteristics of social development during the adolescent period?

Answer: The social development of the adolescent age is marked by the following characteristics:

This is a period of social maturity.
Spirit of independence manifested in interest. Self-assertion is strong and wants to be free from all adult restraints.
There is a marked tendency to rebel against authority.
They are more interested in the ways of adult living and are anxious to be initiated into it.
Habitual obedience to parents and elders is replaced by a spirit of criticism and revolt.
Both boys and girls appreciate each other. At the same time, sexual hypocrisy is seen in them.
They are very much attached to their families. The feeling of family loyalty is so strong that no one tolerates any criticism from any quarter.
Friendships of adolescents is based on their common interests, hobbies, and skills or the satisfaction of their mutual needs and subsequently tend to last longer than the friendships in early childhood. It sometimes ties them in lifelong relationships.
They want recognition and attention from others. They are in search of ‘identity’. They seek to clarify who they are and their role in society.
Adolescents are highly sensitive, idealists, and social reformers by nature. They feel strongly for the weak and sufferers. They are always ready to do some sort of social and community service.

75. What are the characteristics of a socially mature individual? List at least six points.

Answer: Socially mature individuals have the following characteristics:

They like to mix up with people. They are capable of making and keeping friendship.
They are not self-centred. They are always ready to sacrifice their interests for the greater cause of group, society, and nation.
They possess the ability for sharing and shouldering social responsibilities. They are prepared to play the role of a leader or a follower as the situation demands from them.
They are able to make proper decisions and take suitable action at the time on any social crisis, problem or situation in which their help is needed.
They are very much cooperative. They believe in maintaining relationships and working with others.
The area of their social interests and participation is very wide. They possess refined tastes and adequate social etiquettes.

76. Describe the nature of emotional development during adolescence. Why is it a turbulent period?

Answer: During adolescence, individuals experience violent and intensive currents of emotions. The adolescent child remains very tense and anxious, and it is a period of lightning for all emotions like anxiety, fear, love, and anger. Emotions take their roots as sentiments, and self-consciousness, self-respect, and personal pride are increased. They feel strongly, react vigorously, and become introverted, moving into their inner world.

This period is turbulent because at no stage is emotional energy as strong and dangerous as in adolescence. The sudden functioning of sexual glands and a tremendous increase in physical energy make adolescents restless. Their emotions are not consistent; they have very fluctuating emotions which are frequent and quick, making them moody. The emotional balance is disturbed, and proper channelisation of emotional energy is a strong need of this stage.

77. What is the nature of education in infancy? What methods and principles should be applied?

Answer: The education of the infant mostly consists of the training of higher senses, and the apparatus of education has to consist of concrete materials, as in the Montessori Method. The process of education has to consist of activities and concrete experiences. The infant’s course of education must provide for the satisfaction of the instinct of submission and self-satisfaction, as well as for the satisfaction of his/her fantasy. The teacher must see that the infant’s emotional needs are fully satisfied.

The system of reward and punishment can be used for making the infant’s training effective and properly self-governed. School activities should be based on the pleasure-principle, meaning activities in which the infant is mostly interested. The Play-way method may be applied. The child’s experience should be enriched by taking them outdoors to places like fields, parks, and zoos to gain knowledge of the world.

78. How should education be structured during childhood to cater to the child’s needs?

Answer: During childhood, education should be structured to guide the child’s behaviour voluntarily, not through force. Since children are deeply interested in outdoor activities, the teacher must provide varied occupations. The child should be given scope for questioning, and their curiosity must be satisfied with factual information. Learning should be based on the proper arousal of curiosity. The child should be provided opportunities to exercise their constructive instincts, and learning through doing should be a key approach. Methods like the Project method, Heuristic method, Storytelling, and Dramatisation have a strong influence. The school should also satisfy the child’s gregarious instinct through activities like guiding and scouting, and provide for fine arts, games, and other social and community activities.

79. What is the fundamental task of education during adolescence? How can teachers help?

Answer: The fundamental task of education during adolescence is to help adolescents progress towards physical, sexual, mental, and emotional maturity. This can be understood as the ‘fullest development’ of personality, which is the most cherished goal of education.

To help solve the problems of adolescence, the first essential thing for teachers is to develop a warm and genuine interest in them. Acceptance of emotionally disturbed students is a basic principle that helps them understand and deal with their problems, bridging the gap between the teacher and the pupil. A single sentence from a sympathetic teacher can restore self-confidence more effectively than a technical interview. By introducing students to suitable literature, teachers can help satisfy their needs for adventure, love, and affection, which may develop in them a more realistic attitude and understanding of the world.

80. Discuss the pre-natal and post-natal periods of development, listing all stages and their approximate ages.

Answer: The pre-natal and post-natal periods of development, along with their stages and approximate ages, are as follows:
Pre-natal Period (from conception to birth)

1. Germinal Period: First 2 weeks from conception
2. Embryonic Period: From 3 to 8 weeks
3. Foetal Period: From 9 weeks to birth

Post-natal period (from birth to death)

1. Infancy: From birth to 2 years
2. Childhood: From 3 to 12 years or up to the onset of puberty
- (a) Early childhood: From 3 to 6 years
- (b) Later childhood: From 7 to 12 years or up to the onset of puberty
3. Adolescence: From 12 to 19 years or from onset of puberty till attainment of maturity
- (a) Early adolescence: From 12 to 16 years
- (b) Later adolescence: From 17 to 19 years
4. Adulthood: From 20 years to death
- (a) Early adulthood: From 21 to 40 years
- (b) Later adulthood: From 41 to 60 years
5. Old age: From 61 years to death

81. Discuss the ‘Modern Understanding of Infancy’. How has the perception of infants changed from William James’s time?

Answer: The modern understanding of infancy is that it is one of the most remarkable and busiest times of development. The newborn baby, or neonate, enters the world with surprisingly sophisticated perceptual and motor abilities, a set of skills for interacting with people, and a capacity to learn that is put to use immediately after birth. By the end of infancy, the small child is a sociable, self-assertive, purposeful being who walks on his or her own, has developed refined manual skills, and is prepared to acquire language.

This view of the infant has changed drastically over this century. At one time, the newborn baby was considered to be a passive, incompetent being whose world was, in the words of the turn-of-century psychologist William James, “A blooming, buzzing confusion”. Recently developed methods and equipment have shown this image to be wrong. It is now well accepted that infants, from the outset, are skilled and capable beings who display the beginnings of many complex abilities.

82. Describe in detail the physical and social development that occurs during the stage of infancy.

Answer:
Physical Development
During infancy, a baby goes through more changes in his/her body size than at any other time.

Height: Children of the same age vary greatly in height, but the pattern of growth is similar for all. An average Indian child at birth measures between 17 to 21 inches; at one year 28 to 30 inches, and at two years the child is 32 to 34 inches tall, which is almost double his birth length.
Weight: An average Indian newborn weighs 2.5 to 3.25 kg. A loss of weight in a newborn is normal, and by 7-10 days it would regain the lost weight and show an increase. At the age of four months, the baby doubles his/her birth weight, and at the end of the first year, triples it.
Development of Bones: Bone development consists of growth in bone size and change in their composition. Ossification or hardening of the bones mainly takes place during infancy. The bones of babies can be easily deformed because they are soft.
Development of Teeth: Teeth start developing in the baby’s jaws during the third or fourth month of pre-natal life but don’t start appearing until the baby is 5 to 6 months old. They usually come out at a rate of about one tooth a month until the baby is 2 to 2 ½ years old. Out of 20 temporary teeth, about 16 appear by the age of 2 years.
Development in the Nervous System and Eye Muscles: Growth in the nervous system consists primarily of the development of immature cells present at birth. Eye muscles are well coordinated and can distinguish colours.

Social Development
Infancy is centered around home, where foundations for later behaviour and attitudes are formed.

The infant is not social at birth and is too much self-centered, only concerned with the satisfaction of his/her physical needs. An infant cannot share toys and wants to have all things for himself/herself.
The infant is dependent upon adults for the satisfaction of his/her needs, including emotional satisfaction.
During the 1st month, the infant cannot differentiate between human voices and other noises.
During the 2nd month, he/she recognises the sounds of human beings and gives smiles to the person.
During the 3rd month, he/she recognises his/her mother and feels unhappy on separation.
During the 4th month, he/she shows selective attention to the human face and feels happy in their company.
During the 5th month, he/she reacts differently to smiling and scolding and can distinguish between friendly and angry voices.
During the 6th month, he/she recognises familiar persons with a smile and shows a definite expression of fear for strangers.
During the 8th and 9th months, he/she attempts to imitate the speech, simple acts, and gestures observed in others.
Between the 10th and 12th months, he/she plays with his/her image and even kisses it as if it were another person.
At the 12th month, he/she can refrain from doing things in response activities and becomes an active member of the family.
From the 13th to 18th month, the infant’s interest shifts from play materials to playmates.
Between 20-24 months, it co-operates in routine activities like being dressed, fed, and bathed.

83. Explain the emotional and intellectual development that takes place during infancy.

Answer:
Emotional Development
In the beginning of life, emotions are not clear, but as the child grows, different emotions become more clear and can be easily interpreted. The emotional characteristics of infancy are:

Anger: When interfered with its movements, unable to do a task, or for not being understood, the child reacts by screaming, kicking, waving the arms, and jumping up and down.
Fear: Any stimulus which occurs suddenly or unexpectedly or which is different from what the infant is accustomed to gives rise to fear.
Curiosity: Anything new or unusual acts as a stimulus to curiosity, which they express mainly through their facial expressions.
Joy: Joy is stimulated by physical well-being and friendly responses to others. It is expressed through smiling, laughing, baby coos, gurgles, or even shouts with glee.
Affection: Family members, toys, and family pets stimulate the infant’s affection, which it expresses by hugging, patting, and kissing.

The following shows the development of emotions:

At birth: Excitement
3 months: Excitement, distress and delight
6 months: Excitement, distress, delight, fear and anger
12 months: Excitement, distress, delight, fear and anger, elation and affection
18 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy
24 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy, and joy

Intellectual or Mental Development
According to Piaget, infancy is the ‘Sensorimotor Stage’ in conceptual development. Its earliest perceptions come through sensory exploration. The infant understands by:

Looking, listening, smelling, and testing anything that comes its way.
It tries to discover meaning through simpler forms by asking the questions ‘who’, ‘what’, ‘why’.
It associates ideas with objects and situations, resulting in the development of concepts of space, weight, time, self, social, beauty, and comic.

84. Describe the key characteristics of development during the childhood stage across physical, social, and emotional domains.

Answer:
Physical Development
The stage of childhood is characterised as the period of slow, steady, and uniform growth. The development rate is very slow at this stage.

By five years, the height of the child becomes almost double, and he/she acquires almost five times his birth weight.
The arms and legs lengthen and may become spindly, and the hands and feet grow bigger.
The trunk elongates and becomes slimmer, the neck becomes longer, the chest broadens, and the abdomen flattens.
By the time the child completes the age of four, his/her brain gains almost 80% of its final weight, with another 10% being added by the time he/she completes eight years.
The bones ossify at different rates in different parts of the body.
Near the end of the fifth year, the permanent teeth begin to appear.
The nervous system shows rapid growth during the first four years.
The muscles become larger, stronger, and heavier, with the result that children look thinner.
Sexually, this stage is the ‘latency period’, where sexual energy lies dormant.

Social Development

Social behaviour like imitation, co-operation, sympathy, empathy, social approval, sharing, and attachment behaviour to people outside the home are common.
Unsocial patterns like negativism, aggressiveness, selfishness, egocentrism, and prejudices are also developed.
The child desires freedom and takes satisfaction in doing work with his/her own efforts.
He/she shows more interest in outside activities with the peer group than with family members.
He/she becomes an active member of the ‘peer group’, and this stage is referred to as the ‘gang age’.
He/she believes in group loyalty and tries to conform to the rules and values of the group.
A sort of segregation is found among boys and girls, who form their own groups among members of their own sex.
The interests and values of the peer group often clash with those of teachers and parents.

Emotional Development

It is a period of stability and control.
The child learns to hide his/her feelings and expresses emotions in an appropriate and socially approved manner.
Emotional behaviour is not guided by instinctive causes but has an appropriate rationale behind it.
The childhood stage gives birth to many complexes due to inhibition and repression.
The child’s emotional behaviour gets structured into sentiments like religious, moral, patriotic, and aesthetic sentiments, which leads towards character formation.

85. Detail the social and intellectual development that characterizes the childhood years.

Answer:
Social Development

Social behaviour like imitation, co-operation, sympathy, empathy, social approval, sharing, and attachment behaviour to people outside the home are common.
Even unsocial patterns like negativism, aggressiveness, ascendant behaviour, selfishness, egocentrism, destructiveness, prejudices, and sex antagonism are also developed.
At this stage, the child desires freedom and he/she takes satisfaction by doing his/her work with his/her own efforts.
He/she shows interest in outside activities with the peer group more than with parents and family members.
He/she becomes an active member of the ‘peer group’ and this stage is referred to as the ‘gang age’.
He/she believes in group loyalty and thus tries to conform to the rules and the values maintained by the group he/she belongs to.
A sort of segregation is found among boys and girls of this age. They form their own groups among members of their own sex because of a definite and clear differentiation between their habits, interests, and attitudes.
The interests and values of the peer group often have a clash with the interest and values of the teachers and parents.

Intellectual Development
Mental development implies the progressive changes in the mental process which begins at birth and goes on till death. Mental growth continues in childhood. The child seeks to satisfy his/her voracious curiosity by asking an infinite variety of questions, which is why this age is called a questioning age or an exploratory age.

At this stage, reflex actions and instincts develop.
The child’s interests grow in number and extents.
The child develops interests in reading short stories and spends more time in reading history and visiting new places.
At this time, the power of memory increases.
At 6 years, a child displays its ability to distinguish between right and left, to count up to 13 or 14 objects, and to solve problems.
At 7 years, a child tries to distinguish between two objects.
At 8 years, a child is able to repeat sentences containing 16 to 17 words.

86. Explain the physical and sexual development that marks the stage of adolescence.

Answer: Physical Development

The physical growth and development reaches its peak and the human body finds its final shape.
The maximum limit with regard to increase in size, weight, and height is achieved.
Bones and muscles increase to the greatest possible extent, leading to a great increase of motor activity.
Growth of all other inner and outer organs reaches its maximum and almost all the glands become extremely active at this stage.
There is growth of hair under the arms and the genital organs.
Boys and girls develop the characteristic features of their respective sexes.
Girls: There is the roundness of breasts and hip among the girls. Their voice acquires shrillness and becomes sweet and they begin to menstruate monthly during this period.
Boys: Beard and moustaches grow among boys. Their voice deepens and becomes harsher and they have nocturnal emission (discharge of semen during sleep) accompanied by erotic dreams.

Sexual Development: Sexual development reaches its peak during adolescence, and the whole personality structure and behaviour of the adolescent is dominated by sex. During adolescence, sexual development undergoes three stages of change:

Stage of Auto-erotism or Self-love: The adolescent loves his/her body and stands before the mirror for a long time. If he/she has feelings of inadequacy and emotional deprivation, he/she indulges in masturbation, which is not a symptom of emotional abnormality.
Stage of Homo-sexuality: At this stage, boys and girls are attracted toward the members of their own sex and seek gratification from each other’s body by grouping them in two or three at one time. Most often this stage passes on to the next stage, heterosexuality.
Stage of Heterosexuality: At this stage, boys and girls are seen attracted towards each other. They try to attract each other through different ways, like dressing up nicely, better haircut, better manner, politeness in behaviour, and affectionate voice.
Sexual hypocrisy is also seen in them, which is an apparent indifference towards the opposite sex while trying to win their attention. They are very keen to establish friendship or even sexual relationships with members of the opposite sex.

87. Discuss the social development of an adolescent. What are their common interests and characteristics of social maturity?

Answer: Social Development of an Adolescent
Adolescence is a period of rapid change and adjustments, and the social development of this age is marked by the following characteristics:

This is a period of social maturity.
A spirit of independence is manifested in interest. Self-assertion is strong, and the adolescent wants to be free from all adult restraints.
There is a marked tendency to rebel against authority.
They are more interested in the ways of adult living and are anxious to be initiated into it.
Habitual obedience to parents and elders is replaced by a spirit of criticism and revolt.
Both boys and girls appreciate each other. At the same time, sexual hypocrisy is seen in them.
They are very much attached to their families, and the feeling of family loyalty is so strong that no one tolerates any criticism from any quarter.
Friendships of adolescents are based on their common interests, hobbies, and skills and subsequently tend to last longer than friendships in early childhood, sometimes tying them in lifelong relationships.
They want recognition and attention from others. They are in search of ‘identity’ and seek to clarify who they are and their role in society.
Adolescents are highly sensitive, idealists, and social reformers by nature. They feel strongly for the weak and sufferers and are always ready to do some sort of social and community service.

Common Social Interests

Enjoying parties.
Conversations in get-togethers where they talk about things that interest or disturb them.
Helping others when misunderstood, mistreated or oppressed. Group loyalty becomes very much pronounced.
Interests in world affairs, government and politics, through reading and discussions with peers, teachers and parents.
Criticism and reform, which is often destructive in criticism and usually impractical in ‘reformatory’ suggestions.
Taking alcohol or drugs, smoking or playing cards in forbidden areas is also common.
The occupational choices have a big role in social development, as they want to be self-dependent.

Characteristics of Social Maturity

They like to mix up with people and are capable of making and keeping friendship.
They are not self-centred and are always ready to sacrifice their interests for the greater cause of group, society, and nation.
They possess the ability for sharing and shouldering social responsibilities.
They are able to make proper decisions and take suitable action at the time on any social crisis.
They are very much cooperative and believe in maintaining relationships and working with others.
The area of their social interests and participation is very wide. They possess refined tastes and adequate social etiquettes.
Their social behaviour conforms to the norms, social codes, and ethics.
They possess a strong desire to serve the cause of society and try to bring desirable reforms.
They possess a greater degree of adaptability and adjustability.

88. Describe the emotional and intellectual awakening that occurs during adolescence.

Answer: Emotional Development

Adolescents experience violent and intensive currents of emotions. At no stage is this emotional energy as strong and dangerous as in adolescence.
They are not consistent in their emotions. They have very fluctuating emotions, which are frequent and quick, making them moody.
The emotional balance is disturbed, and proper channelisation of emotional energy is a strong need of this stage.
The adolescent child remains very tense and anxious. It is the period of lightning of all emotions like anxiety, fear, love, and anger.
Emotions take their roots as sentiments. Self-consciousness, self-respect, and personal pride are too increased.
He/she feels strongly and reacts vigorously, becomes an introvert, and moves in the inner world, generally in a thinking mood.
Everything in the world is strange and puzzling to the young adolescent.
Birth of religious emotions, expressed as love towards other religions, missionary zeal, and altruism towards all mankind, emerge during this period.
Vague and mysterious ideals and habits of frequent self-inspection and masturbation develop and weaken the body and mind.
They develop many complexes and think of themselves as beyond redemption. They are hunted by a sense of sin, fear, anxiety, and depression.

Intellectual Development: There is great intellectual awakening during adolescence, but it does not show the same positive acceleration found in physical traits. Development in intelligence reaches its final stage late in adolescence. Adolescents engage in a larger and more complex range of activities. Curiosity is at its height. The adolescent may develop a special aptitude for music or language, develop mechanical aptitudes, or begin composing poems. He/she begins to appreciate literature. His/her vocabulary widens, and they enjoy debates, discussions, and dramas. The urge for self-expression is very great, which may result in writing, acting, or painting. The adolescent has a desire for responsibility but also has a tendency to be irresponsible. He/she is impatient for the results and is very enthusiastic.

89. Explain the educational significance of the infancy and childhood stages of human development.

Answer: Nature of Education in Infancy: The education of the infant mostly consists of the training of higher senses, and the apparatus of education has to consist of concrete materials, as in the Montessori Method. The process of education has to consist of activities and concrete experiences. The infant’s course of education must provide something for the satisfaction of the instinct of submission and self-satisfaction, and also have provision for the satisfaction of his/her fantasy. The teacher has to see that the infant’s emotional needs are fully satisfied. The system of reward and punishment can be utilised for making the infant’s training effective and properly self-governed. School activities should be based on the pleasure-principle, i.e., activities in which he/she is mostly interested. The play-way method may be applied. The child’s experience should be enriched by taking them outdoors to fields, parks, and zoos to have knowledge of the world.

Nature of Education in Childhood: Childhood is the time when the individual’s basic values and ideals are to a great extent shaped. The child thinks more of the objective environment of things and persons other than himself/herself. Behaviour should be voluntary and not be dominated by force, but should be guided. The teacher must provide varied occupations for outdoor activities such as running, climbing, and jumping. The child should be given scope for questioning, and his/her curiosity must be satisfied by giving factual information. Learning at this stage should be based through the proper arousal of curiosity. The child should be provided opportunities for the exercise of his/her constructive instincts, and learning through doing should be emphasised. Methods like Project method, Heuristic method, Storytelling, and Dramatisation exert strong influence. The school should have provision for fine arts, games, and other outdoor, social, and community activities.

90. Discuss the nature of education required during adolescence. How can teachers and schools support their development?

Answer: The parents and society both expect that adolescents should progress towards physical, sexual, mental, and emotional maturity. To help them march ahead steadily in this direction is the fundamental task of education.

To solve the problems of adolescence, the first essential thing for teachers is to develop a warm and genuine interest in them. Acceptance of emotionally disturbed students by their teachers is the basic principle. This helps students to understand and deal with their problems and bridges the gap between the teacher and the pupil, which is the basis of emotional security. A single sentence of a sympathetic teacher can be more helpful than a long technical interview. By introducing them to suitable literature, teachers can help them satisfy their needs for adventure, love, and affection.

Since the sex instinct is very intense, there is an urgent need for sex education, which should be given in plain, straightforward talk. To satisfy curiosity and for sex sublimation, different types of creative activity are a better method of channelising sex drives. The adolescent has to be provided hard physical activities to exercise his/her fully developed physique. The curriculum should supply enough material for the satisfaction of his/her thirst. The hero-worship attitude may be directed towards desirable qualities from real life or history. To avoid self-consciousness and daydreaming, the teacher should keep the individual occupied in various games, co-curricular activities, and debates. Proper vocational guidance should be given. The school should seek a cultural unity for humanity as a whole. Abundance of interesting material, manual work, plenty of outdoor exercise, games, and regular sleep all play their part in the sublimation of the tendency during this critical period.

91. Provide a comprehensive overview of the stages of human development, from the pre-natal period to old age. Discuss the continuous yet stage-like nature of this process.

Answer: One of the most important features of all living beings is change, and these changes are most striking in the human life span from conception to death. Even though development is a continuous process, some theorists believe that various stages can be identified for the sake of locating major shifts and determining developmental tasks. This helps in monitoring the pace of developmental changes. It must be pointed out that there is no sharp dividing line between them. Each stage has certain characteristic features and prepares the ground for the next stage. Some theorists, like Piaget and Freud, have suggested stages in specific areas of development, such as cognitive and psycho-sexual development, respectively.

The entire life span of an individual is divided into various stages. All individuals have to pass through these stages of human development. Though the stages of development are universally recognised, the exact age range is arbitrary and depends on cultural factors. The stages are as follows:
Pre-natal Period (from conception to birth)

1. Germinal Period: First 2 weeks from conception
2. Embryonic Period: From 3 to 8 weeks
3. Foetal Period: From 9 weeks to birth

Post-natal period (from birth to death)

1. Infancy: From birth to 2 years
2. Childhood: From 3 to 12 years or up to the onset of puberty
- (a) Early childhood: From 3 to 6 years
- (b) Later childhood: From 7 to 12 years or up to the onset of puberty
3. Adolescence: From 12 to 19 years or from onset of puberty till attainment of maturity
- (a) Early adolescence: From 12 to 16 years
- (b) Later adolescence: From 17 to 19 years
4. Adulthood: From 20 years to death
- (a) Early adulthood: From 21 to 40 years
- (b) Later adulthood: From 41 to 60 years
5. Old age: From 61 years to death

92. “Infancy is one of the most remarkable and busiest times of development.” Elaborate on this statement by discussing the physical, social, emotional, and intellectual development during this stage.

Answer: Although it comprises only 2 per cent of the life span, infancy is one of the most remarkable and busiest times of development. The newborn baby, or neonate, enters the world with surprisingly sophisticated perceptual and motor abilities, a set of skills for interacting with people, and a capacity to learn that is put to use immediately after birth. By the end of infancy, the small child is a sociable, self-assertive, purposeful being who walks on his/her own, has developed refined manual skills, and is prepared to acquire language.

General notions of infancy include it being an age of dependence, an age of rapid growth and change, the foundation age for behaviours and attitudes, a shy age limited to family, and a hazardous age due to proneness to illnesses.

Physical Development:

Height: An average Indian child at birth measures between 17 to 21 inches. At two years, the child is 32 to 34 inches tall, almost double his birth length.
Weight: An average Indian newborn weighs 2.5 to 3.25 kg. At the age of four months, he/she doubles his/her birth weight, and at the end of the first year, triples it.
Development of Bones: Ossification or hardening of the bones mainly takes place during infancy. The bones of babies are soft and can be easily deformed.
Development of Teeth: Teeth start appearing when the baby is 5 to 6 months old, at a rate of about one tooth a month. Out of 20 temporary teeth, about 16 appear by the age of 2 years.
Development in the Nervous System and Eye Muscles: Growth in the nervous system consists primarily of the development of immature cells present at birth. Eye muscles are well coordinated and can distinguish colours.

Social Development:

The infant is not social at birth and is too much self-centered, only concerned with the satisfaction of physical needs. During the 2nd month, he/she recognises the sounds of human beings and gives smiles. During the 3rd month, the infant recognises his/her mother. During the 6th month, he/she recognises familiar persons with a smile and shows fear for strangers. During the 8th and 9th months, the infant attempts to imitate speech and simple acts. Between 20-24 months, the infant co-operates in routine activities like being dressed and fed.

Emotional Development: In the beginning of life, emotions are not clear but become more interpretable as the child grows.

Anger: The child reacts by screaming and kicking when interfered with.
Fear: Any sudden or unexpected stimulus gives rise to fear.
Curiosity: Anything new or unusual acts as a stimulus to curiosity.
Joy: Stimulated by physical well-being, it is expressed through smiling and laughing.
Affection: Expressed by hugging, patting, and kissing family members and pets.

The development of emotions progresses as follows:

At birth: Excitement
3 months: Excitement, distress and delight
6 months: Excitement, distress, delight, fear and anger
12 months: Excitement, distress, delight, fear and anger, elation and affection
18 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy
24 months: Excitement, distress, delight, fear and anger, elation and affection for adults and children, jealousy, and joy

Intellectual or Mental Development: According to Piaget, this is the ‘Sensorimotor Stage’. Its earliest perceptions come through sensory exploration. The infant understands by looking, listening, smelling, and testing anything that comes its way. It tries to discover meaning through simpler forms by asking ‘who’, ‘what’, ‘why’ and associates ideas with objects and situations, resulting in the development of concepts of space, weight, time, self, social, beauty, and comic.

93. “During the childhood period significant changes in the sphere of physical, social, emotional, and intellectual aspects take place.” Discuss this statement in detail, providing characteristics for each domain of development during childhood.

Answer: During the childhood period, significant changes in the sphere of physical, social, emotional, and intellectual aspects take place. The main characteristics of development during this stage can be named as follows:

Physical Development: The stage of childhood is characterised as the period of slow, steady, and uniform growth. By five years, the height of the child approximately becomes almost double, and he/she acquires almost five times his birth weight. The arms and legs lengthen, the trunk elongates and becomes slimmer, and the abdomen flattens. By the time the child completes the age of four, his/her brain gains almost 80% of its final weight. The bones ossify at different rates, and near the end of the fifth year, permanent teeth begin to appear. The nervous system shows rapid growth during the first four years, and muscles become larger and stronger. Sexually, this stage is a ‘latency period’ where sexual energy lies dormant.

Social Development: Social behaviour like imitation, co-operation, sympathy, and attachment to people outside the home are common. Even unsocial patterns like negativism, aggressiveness, and egocentrism are also developed. The child desires freedom and takes satisfaction in doing work with his/her own efforts. He/she shows interest in outside activities with the peer group, becomes an active member of the ‘peer group’, and this stage is referred to as the ‘gang age’. The child believes in group loyalty and conforms to its rules. A sort of segregation is found among boys and girls, who form their own groups. The interests and values of the peer group often have a clash with those of teachers and parents.

Emotional Development: This is a period of stability and control. The child learns to hide his/her feelings and expresses emotions in an appropriate and socially approved manner. His/her emotional behaviour is not guided by instinctive causes but has an appropriate rationale behind it. The childhood stage gives birth to many complexes due to inhibition and repression. In this stage, the child’s emotional behaviour gets structured into sentiments like religious, moral, patriotic, and aesthetic sentiments, which leads towards character formation.

Intellectual Development: Mental development continues in childhood. The child seeks to satisfy his/her voracious curiosity by asking an infinite variety of questions, which is why this age is called a questioning age or an exploratory age. At this stage, reflex actions and instincts develop, and the child’s interests grow in number and extent, including interests in reading short stories and history. The power of memory increases. Specific milestones include:

At 6 years, a child can distinguish between right and left and count up to 13 or 14 objects.
At 7 years, a child tries to distinguish between two objects.
At 8 years, a child is able to repeat sentences containing 16 to 17 words.
At 9 years, a child becomes conscious of day, time, and date and recognises coins.
At 10 years, a child points out mistakes in short sentences and repeats 60-70 words in three minutes.
At 11 years, a child can recognise similarity and differences and make comparisons.
At 12 years, a child points out the cause of a thing and provides his own explanation.

94. “Adolescence represents a period of intensive growth and change in nearly all aspects of a child’s physical, mental, social, and emotional life.” Elaborate on this.

Answer: The word ‘adolescence’ comes from the Latin word ‘adolescere’ which means ‘to grow’. So the essence of the word adolescence is growth, and it represents a period of intensive growth and change in nearly all aspects of a child’s physical, mental, social, and emotional life.

Physical Development: The physical growth and development reaches its peak, and the human body finds its final shape. The maximum limit with regard to increase in size, weight, and height is achieved. Bones and muscles increase to the greatest possible extent, leading to a great increase in motor activity. There is growth of hair under the arms and the genital organs. Boys and girls develop the characteristic features of their respective sexes.

Girls: There is the roundness of breasts and hip. Their voice acquires shrillness and becomes sweet, and they begin to menstruate.
Boys: Beard and moustaches grow. Their voice deepens and becomes harsher, and they have nocturnal emission.

Sexual development reaches its peak and undergoes three stages of change:

Stage of Auto-erotism or Self-love: The adolescent loves his/her body and may indulge in self-stimulation of the genitals.
Stage of Homo-sexuality: Boys and girls are attracted toward members of their own sex.
Stage of Heterosexuality: Boys and girls are seen attracted towards each other and try to attract each other through different ways, like dressing up nicely and politeness in behaviour.

Social Development: Adolescence is a period of rapid change, adjustments, and social maturity. Characteristics include a spirit of independence, a marked tendency to rebel against authority, and an interest in the ways of adult living. Habitual obedience is replaced by a spirit of criticism and revolt. Friendships are based on common interests and skills and tend to last longer. They want recognition and attention from others and are in search of ‘identity’. Adolescents are highly sensitive, idealists, and social reformers by nature, feeling strongly for the weak and sufferers. Common social interests include enjoying parties, having conversations in get-togethers, and helping others.

Emotional Development: Adolescents experience violent and intensive currents of emotions. At no stage is this emotional energy as strong and dangerous. They are not consistent in their emotions, which are fluctuating, frequent, and quick, making them moody. The emotional balance is disturbed, and the adolescent child remains very tense and anxious. It is the period of lightning of all emotions like anxiety, fear, love, and anger. Emotions take their roots as sentiments like self-consciousness, self-respect, and personal pride. The adolescent feels strongly, reacts vigorously, and becomes introvert, moving in the inner world. Birth of religious emotions, missionary zeal, and altruism emerge during this period. They may also develop many complexes and think of themselves as beyond redemption, hunted by a sense of sin, fear, anxiety, and depression.

Intellectual Development: There is great intellectual awakening. Adolescents engage in a larger and more complex range of activities, and curiosity is at its height. They may develop a special aptitude for music or language, begin composing poems, and appreciate literature. His/her vocabulary widens, and they enjoy debates and discussions. The urge for self-expression is very great, which may result in writing, acting, or painting. The adolescent has a desire for responsibility but also has a tendency to be irresponsible. He/she is impatient for the results and is very enthusiastic.
