NIMA WANGDI BIO CHE FIRST YEAR 2011 Theories of child development PSYCHOANALYTIC THEORY OF DEVELOPMENT/THE PSYCHOANALYTIC PERSPECTIVE According to the psychoanalytic approach, children move through a series of stages in which they confront conflicts between biological drives and social expectations. The way these conflicts are resolved determines psychological adjustment, i.e., the individual’s ability to learn, to get along with others, and to cope with anxiety. Although many individuals contributed to the psychoanalytic perspective, two have been especially influential: Sigmund Freud, founder of the psychoanalytic movement, and Erik Erikson. FREUD’S THEORY Freud (1856-1939), a Viennese physician, saw patients in his practice with a variety of nervous symptoms—such as hallucinations, fears, and paralyses—that appeared to have no physical basis. Seeking a cure for these troubled adults, Freud found that their symptoms could be relieved by having patients talk freely about painful events of their childhood. On the basis of adult remembrances, he examined the unconscious motivations of his patients and constructed his psychosexual theory of development. It emphasized that how parents manage their child’s sexual and aggressive drives in the first few years is crucial for healthy personality development. Three Parts of the Personality In Freud’s theory, three parts of the personality—id, ego, and superego—become integrated during a sequence of five stages of development. The id, the largest portion of the mind, is the source of basic biological needs and desires. The ego—the conscious, rational part of personality—emerges in early infancy to redirect the id’s impulses so they are discharged on appropriate objects at acceptable times and places. For example, aided by the ego, the hungry baby of few months of age stops crying when the child sees the mother unfasten her clothing for breast-feeding or warm a bottle. And the more competent preschooler goes into the kitchen and gets a snack on his/her own. Between 3 and 6 years of age, the superego, or conscience, develops from interactions with parents, who eventually insist that children conform to the values of society. Now the ego faces the increasingly complex task of reconciling the demands of the id, the external world, and conscience. For example, when the ego is tempted to gratify an id impulse by hitting a playmate to get an attractive toy, the superego may warn that such behaviour is wrong. The ego must decide which of the two forces (id or superego) will win this inner struggle or work out a reasonable compromise, such as asking for a turn with the toy. According to Freud, the relations established between the id, ego, and superego during the preschool years determine the individual’s basic personality. PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 1 NIMA WANGDI BIO CHE FIRST YEAR 2011 Psychosexual Development Freud believed that over the course of childhood, sexual impulses/stimulation shift focus from the oral to the anal regions of the body. In each stage of development, parents walk a fine line between permitting too much or too little gratification of their child’s basic needs. If parents strike an appropriate balance, then children grow into well-adjusted adults with the capacity for mature sexual behaviour, investment in family life, and rearing of the next generation. The following table shows some of the important characteristics of the five stages of psychosexual development. Freud’s Psychosexual Stages Psychosexual Stage Oral Period of Development Birth-1year Anal 1-3 years Phallic 3-6 years Description The new ego directs the baby’s sucking activities toward breast or bottle. The oral region becomes the most sensitive erogenous zone. If oral needs are not met appropriately, the individual may develop such habits as thumb sucking, fingernail biting, and pencil chewing in childhood and overeating in later life. Young toddlers and preschoolers enjoy holding and releasing urine and feces. When the child reaches this stage, the erogenous zone shifts from the oral region to the anal region. Toilet training becomes a major issue between parent and child. If parents insist that children be trained before they are ready or make too much demands, conflicts about anal control may appear in the form of extreme orderliness and cleanliness or messiness and disorder. Id impulses transfer to the genitals, and child finds pleasure in genital stimulation. Freud’s Oedipus conflict for boys and Electra conflict for girls develop or take place. Young children feel a sexual desire for the opposite-sex parent. To avoid punishment, they give up this desire and, instead, adopt the same-sex parent’s characteristics and values. As a result the superego is formed, and children feel guilty each time they violate its standard. The relations between id, ego, and superego established at this time determine the individual’s basic personality orientation. Latency 6-11 years Sexual instincts die down, and the superego develops PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 2 NIMA WANGDI BIO CHE FIRST YEAR 2011 further. The child acquires new social values from adults outside the family and from play with samesex peers. Genital Adolescence Puberty causes the sexual impulses of the phallic stage to reappear. If development has been successful during earlier stages, it leads to marriage, mature sexuality, and the birth and rearing of children. Freud’s psychosexual theory highlighted the importance of family relationships for children’s development. It was the first theory to stress the role of early experience. But Freud’s perspective was eventually criticized for several reasons. First, the theory overemphasized the influence of sexual feelings in development. Second, because it was based on the problems of sexually repressed, well-to-do adults, it did not apply in different cultures from nineteenth-century Victorian society. Finally, Freud’s ideas were called into question because he did not study children directly. ERIKSON”S THEORY Several of Freud’s followers took what was useful from his theory and stretched and rearranged it in ways that improved on his idea. The most important of neo-Freudians for the field of child development is Erik Erikson (1902-1994). Psychosocial Theory Erik Erikson expanded Freud’s theory, emphasizing the psychosocial outcomes of development. Erikson expanded on Freud’s theory by emphasizing that the ego is a positive force in development, ensuring that individuals acquire attitudes and skills that help them become active, contributing members of the society. Erikson was also one of the first to recognize the lifespan nature of development and the impact of culture on one’s individual development. PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 3 NIMA WANGDI BIO CHE FIRST YEAR 2011 Erikson’s Psychosocial Stages Psychosocial Period of Stage Development Description Basic trust vs. mistrust Birth-1 year From warm, responsive care, infants gain a sense of trust, or confidence, that the world is good. Mistrust occurs when infants have to wait too long for comfort and are handled harshly. Autonomy vs. shame & doubt 1-3 years Using new mental and motor skills, children want to choose and decide for themselves. Autonomy is fostered when parents permit reasonable free choice and do not force or shame the child. Corresponding Psychosexual Stage Oral Anal Phallic Initiative vs. guilt 3-6 years Industry vs. inferiority 6-11 years Identity vs. identity confusion Adolescence Intimacy vs. isolation Young adulthood Through make-believe play, children experiment with the kind of person they can become. Initiative—a sense of ambition and responsibility— develops when parents support their child’s new sense of purpose and direction. The danger is that parents will demand too much self-control, which leads to overcontrol, or too much guilt. At school, children develop the capacity to work and cooperate with other. Inferiority develops when negative experiences at home, at school. Or with peers lead to feelings of incompetence and inferiority. The adolescent tries to answer the questions, Who am I, and What is my place in society? Self-chosen values and vocational goals and lead to a lasting personal identity. The negative outcome is confusion about future adult roles. Latency Genital Young people work on establishing PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 4 NIMA WANGDI BIO CHE FIRST YEAR 2011 Generativity Middle adulthood vs. stagnation Old age Ego integrity vs. despair intimate ties. Because of earlier disappointments, some individuals cannot form close relationships and isolated from others. Generativity means giving to the next generation through child rearing, caring for other people, or productive work. The person who fails in these ways feels an absence of meaningful accomplishment. In this final stage, individuals reflect on the kind of person they have been. Integrity results from feeling that life was worth living as it happened. Old people are dissatisfied with their lives fear death. Contributions and Limitations of the Psychoanalytic Perspective A special strength of psychoanalytic perspective is its emphasis on the individual’s unique life history as worthy of study and understanding (Emde, 1992). Psychoanalytic theory has also inspired a wealth of research on many aspects of emotional and social development, including infant-caregiver attachment, aggression, sibling relationship, child-rearing practices, morality, gender roles, and adolescent identity. Despite its extensive contributions, the psychoanalytic perspective is no longer in the mainstream of child development research (Cairns, 1998; Miller, 1993). Psychoanalytic theorists may have become isolated from the rest of the field because they were so strongly committed to the clinical approach that they failed to consider other methods. In addition, many psychoanalytic ideas, such as Freud’s Oedipus conflict and the psychosexual stages, are so vague and subject to interpretation that they are difficult or impossible to test empirically.

PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 5 NIMA WANGDI BIO CHE FIRST YEAR 2011 Behavioural theory At about the same time in the early 20th century that psychodynamic theory was attracting increased attention, John Watson (1878 – 1958) was among the first psychologists to champion the English philosopher John Locke’s view that the infant’s mind is a blank slate on which experience writes. Watson agued that learning determines what children will be. He assumed that, with the correct techniques, anything could be learned by almost anyone. In other words, in Watson’s views, experience was just about all that mattered in determining the course of development. B.F Skinner (1904 – 1990) supported this view with his study of operant conditioning, in which the consequence of a behavior determines whether a behavior is repeated in the future. Skinner showed that two kinds of consequences were hood especially influential. Reinforcement is a consequence that increases the future likelihood of the behavior that it follows. Positive reinforcement consists of giving a reward such as chocolate or gold stars to increase the likelihood of previous behavior. A father who wants his daughter to help with chores may reinforce with praises, food treats or money whenever she cleans her room. Negative reinforcement consists of rewarding people by taking away unpleasant things. The same father could use negative reinforcement by saying that whenever his daughter cleans her room she doesn’t have to wash the dishes or fold laundry. A punishment is a consequence that decreases the future likelihood of the behavior that it follows. Punishment suppresses a behavior by either adding something aversive or by withholding a pleasant event. Should the daughter fail to clean her room, the father may punish her by nagging (adding something aversive) or by not allowing her to watch television (withholding a pleasant event). Human development researcher also showed that the principles of operant conditioning could be extended readily to people (Baer & Wolf, 1968). Berk, L. E. (2004). Development through the lifespan. 3rd (edn) Boston: Allyn & Bacon Social learning theory Researchers discovered that people sometimes learn without reinforcement and punishment. People learn much by simply watching those others around them, which is known as imitation or observational learning. perhaps imitation makes you think of “monkey-see, monkey-do”, in which people simply mimic what they see. Later investigations showed that people are more likely to imitate if the person thay see is popular, smart or talented. They are more likely to imitate when the behavior they see is rewarded than when it is punished. Findings like this imply that imitation is more complex than sheer mimicry. Albert bandura (1918- ) based his social-cognitive theory on this more complex view of reward, punishment, and imitation. Bandura’s theory is “cognitive” because he believes people actively try to understand what goes on in their world; the theory is “social” because, along with PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 6 NIMA WANGDI BIO CHE FIRST YEAR 2011 reinforcement and punishment, what other people do is an important source of information about the world. Bandura also argues that experience gives people a sense of self efficacy, which refers to people’s beliefs about their own abilities and talents. Self efficacy beliefs help to determine when people will imitate others. A child who sees herself as athletically untalented, for example, will not try to imitate Shaquille O’ Neal dunking a basketball despite the fact that he is obviously talented and popular. Thus, whether that people will imitate others depend on who the other person is, whether that person’s behavior is rewarded, and the person’s beliefs about his or her talents. Kail, R.V & Cavanaugh, J. C., (2004), Human Development – A life-span view, 3rd (ed), USA, Thomson & Wadsworth Cognitive theory (PIAGET: 1896-1980) According to Piaget’s cognitive-developmental theory, children actively construct knowledge as they manipulate and explore their world, and their cognitive development takes place in stages. Piaget did not believe that knowledge was imposed on a passive, reinforced child. Piaget’s Stages of Development Central to his theory is the biological concept of adaptation (Piaget, 1971). Just as the structures of the body are adapted to fit with the environment, so the structures of the mind develop during childhood to better fit with, or represent, the external world. In infancy and early childhood, children’s understanding is very different from adults. For example, Piaget believed that young babies, do not realize that an object hidden from view—a favorite toy or even the mother— continues to exist. He also concluded that that preschoolers’ thinking is full of faulty logic. For instance, children younger than age 7 commonly say that the amount of milk or water changes when it is poured into a differently shaped container. According to Piaget, children eventually revise these incorrect ideas in their ongoing efforts to achieve equilibrium, or balance, between internal structures and information they encounter in their everyday worlds (Beilin, 1992; Kuhn, 1992). In Piaget’s theory, as the brain matures and children’s experiences expand, they move through four broad stages of development, each of which is characterized by qualitatively distinct ways of thinking. The table below provides a brief description of Piaget’s stages. In the sensorimotor stage, cognitive develop begins with the baby’s use of senses and movements to explore the world. These action patterns evolve into the symbolic but illogical thinking of the preschoolers in the preoperational stage. Then cognition is transformed into the more organized reasoning of the school-age child in the concrete operational stage. Finally, in the formal operational stage, thought becomes the complex, abstract reasoning system of the adolescent and adult. PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 7 NIMA WANGDI BIO CHE FIRST YEAR 2011 Piaget’s Stages of Cognitive Development Stage Period of Description Development Infants “think” by acting on the world with their eyes, ears, and hands. As a result, they invent ways of solving Sensorimotor Birth-2 sensorimotor problems, such as pulling a lever to hear years the sound of a music box, finding hidden toys, and putting objects in and taking them out of containers. Preschool children use symbols to represent their earlier sensorimotor discoveries. Language and make-believe Preoperational 2-7 years play develop. However, thinking lacks the logical qualities of the two remaining stages. Children’s reasoning becomes logical. School-age 7-11 years children understand that a certain amount of water or Concrete play dough remains the same even after its appearance operational changes. They also organize objects into hierarchies of classes and subclasses. However, thinking falls short of adult intelligence. It is not yet abstract. The capacity for abstract thinking permits adolescents to reason with symbols that do not refer to objects in the 11 years Formal real world, as in advanced mathematics. They can also on operational think of all possible outcomes in a scientific problem, not just the obvious ones. Contributions and Limitations of Piaget’s Theory Piaget’s cognitive developmental-perspective convinced the field that children are active learners whose minds consist of rich structures of knowledge. Besides investigating children’s understanding of the physical world, Piaget explored their reasoning about the social world. Piaget’s stages of cognitive development have sparked a wealth of research on children’s conceptions of themselves, other people, and human relationships. Piaget’s theory encouraged the development of educational philosophies and programs that emphasize discovery learning and direct contact with the environment. Despite Piaget’s overwhelming contributions to child development and education, in recent years his theory has been challenged. Research indicates that Piaget underestimated the competencies of infants and preschoolers. For example, it has been found that when young children are given tasks scaled down in difficulty, their understanding appears close to that of the older child and adult than Piaget believed. This discovery has led many researchers to conclude that the maturity of children’s thinking may depend on their familiarity with the task and the kind of knowledge sampled. Finally, many studies show that children’s performance on Piagetian problems can be improved with training. This finding raises questions about his assumption that discovery learning rather than adult teaching is the best way to foster development. PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 8 NIMA WANGDI BIO CHE FIRST YEAR 2011 Today, the field of child development is divided over its loyalty to Piaget’s ideas. Those who continue to find merit in Piaget’s approach accept a modified view of his cognitive stages—one in which changes in children’s thinking are not sudden and abrupt but take place much more gradually than Piaget believed (case, 1992, 1998; Fischer & Pipp, 1984). Other have given up the idea of cognitive stages in favor of a continuous approach to development—information processing. (Berk, L. E. (2000). Child development (5th ed.). Boston: Allyn & Bacon) VYGOTSKY’S SOCIOCULTURAL THEORY Lev Semenovich Vygotsky (1896-1934), the Russian psychologist’s sociocultural theory focuses on how culture—the values, beliefs, and customs, and skills of a social group—is transmitted to the next generation. According to Vygotsky, social interaction—in particular, cooperative dialogues between children and more knowledgeable members of society—is necessary for children to acquire the ways of thinking and behaving that make up a community’s culture. Vygotsky believed that as adults and more expert peers help children master culturally meaningful activities, the communication between them becomes part of children’s thinking. As children internalize the essential features of these dialogues, they use the language within them to guide their own thought and actions and acquire new skills. Vygotsky’s theory has also been influential in the study of children’s cognition. But Vygotsky’s approach to cognitive development is different from Piaget’s. Piaget, unlike Vygotsky, did not regard direct teaching by adults as important for cognitive development. Instead, he emphasized children’s active, independent efforts to make sense of their world. Vygotsky agreed with Piaget that children are active, constructive beings. But unlike Piaget, Vygotsky viewed cognitive development as a socially mediated process—as dependent on the support that adults and more mature peers provide as children try new tasks. Finally, Vygotsky did not regard all children as moving through the same sequence of stages. Instead, as soon as children acquire language, their enhanced ability to communicate with others leads to continuous changes in thought and behaviour that can vary greatly from culture to culture. A major finding of cross-cultural and multicultural research is that cultures select different tasks for children’s learning. In line with Vygotsky’s theory, social interaction surrounding these tasks leads to knowledge and skills essential for success in a particular culture. For example, among the Zinacanteco Indians of southern Mexico, girls become expert weavers of complex garments at an early age through the informal guidance of adult experts (Childs & Greenfield, 1982). PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 9 NIMA WANGDI BIO CHE FIRST YEAR 2011 Contributions and Limitations of Sociocultural Theory Vygotsky’s theory and the research stimulated by it reveal that children in every culture develop unique strengths that are not present in other cultures. However, Vygotsky’s emphasis on culture and social experience led him to neglect the biological side of development. Although he recognized the importance of biology, he said little about the role of heredity and brain growth in cognitive change. Furthermore, Vygotsky’s focus on social transmission of knowledge meant that he placed less emphasis than did other theorists on children’s capacity to shape their own development. ETHOLOGY An approach concerned with the adaptive, or survival, value of behaviour and its evolutionary history. The origins of ethology can be traced to the work of Darwin. Two European zoologists, Konrad Lorenz and Niko Tinbergen, laid its modern foundations. Watching the behaviours of diverse animal species in their natural habitats, Lorenz and Tinbergen observed behaviour patterns that promote survival. The best known of these is imprinting, the early following behaviour pattern of certain baby birds that ensures that the young will stay close to the mother and be fed and protected from danger. Imprinting takes place during an early restricted time period of development. If the mother goose is not present during this time, but an object resembling her in important features is, young goslings may imprint on it instead. Observations of imprinting led to a major concept that has been widely applied in child development: the critical period, now referred to as sensitive period for it term offers a better account of human development than does the term critical period. A sensitive period is a time that is optimal for certain capacities to emerge and in which the individual is especially responsive to environmental influences. Inspired by observation of imprinting, British psychoanalyst John Bowlby (1969) applied ethological theory to the understanding of the human infant—caregiver relationship. He argued that attachment behaviours of babies, such as smiling, babbling, grasping, and crying, are built-in social signals that encourage the parent to approach, care for, and interact with the baby. By keeping the mother near, these behaviours help ensure that the infant will be fed, protected from danger, and provided with stimulation and affection necessary for healthy growth. PSYCHOLOGY CHILD DEVELOPMENT THEORY Page 10 NIMA WANGDI BIO CHE FIRST YEAR 2011 Ecological Systems Approach In essence the Ecological Systems Approach is the acceptance of a new perspective on the child’s behaviour, and how it relates to other areas of the child’s existence outside the school perspective. How many times when discussing a pupil’s behaviour in class, have teachers at a parents evening heard the parents saying “well they're never like this at home” or “are you sure you’ve got the right child”. This is due to the parents' own perspective of the child behaviour within their family “system”. This approach sees the development of both normal and abnormal behaviour as a product of the child’s environment. All aspects of the child’s environment must be considered. In order to comprehend better the EBD child in the classroom, one must not just seek to understand the child’s teacher and classmate experiences, but also the child’s experiences within their family, neighbourhood and community. This is known as the Child’s System. Emotional and Behavioural Difficulties are seen as the result of discrepancies between the child’s skills and abilities, and the demands and expectations placed on the child within the environment that they are existing within at that time. The theoretical origins of this perspective rest on Ludwig von Bertalanffy’s “General System Theory” (1950, 1968). In this human beings are seen as existing in a social web (similar to a biological ecosystem). The individual’s behaviour and development is both influenced by, as well as an influence on, the behaviour and development of others with whom they interact in the web. Thus human behaviour is the product of an ongoing interaction between social environments and internal motivations (gained from previous social experiences). These systems include the home, family, religion, culture, sub-culture, community, as well as school. There are always interconnected elements between these systems. Hence any alteration in one system can have repercussions in the others. For example in a social system (e.g. the family), there is a change within a part of the system (e.g. the parental relationship), this affects the whole social system (e.g. also affects children of family), which may influence allied systems (e.g. school).
