Case Study: Developmental Psychology

In the “Study of the Child: Theories of Development I” (Learning Seed, 1997), according to Vygotsky, the cognitive development in children is in direct relationship, and dependent on interaction with others. (Feldman 2010, pg. 20). Vygotsky believed to truly understand cognitive development; a child’s social and cultural experiences must be considered.

Developmental Child Psychology has been defined as a field of study that examines and attempts to explain why and how human beings change and develop over time. Changes include physical change, mental change and social change.

The teacher could place two cups that have the same amount of liquid in the cups but because one of the cups is taller than the other the child is going to think the taller glass has more liquid in it. The third stage is the concrete operational stage which occurs during ages seven to eleven. The term concrete operational means the child can reason only about tangible objects presents. So the child can conserve and think logically but only with practical aids. Thinking becomes less egocentric with increased awareness of external events. The fourth and final stage is the formal operational stage which occurs during ages eleven to fifteen. This stage focuses on hypothetical thinking and scientific reasoning. Piaget believed that only children can learn when they are ‘ready’ to learn. He also believed that development couldn 't be ‘sped up.’ Piaget believed that children learned through the resolution of disequilibrium (self discovery, active participation). He believed that teachers should ‘bend’ to children’s needs, provide an appropriate environment, promote self discovery, exploratory learning, self-motivated learning, and set challenges to existing schemes.

There are three main theories of development that I shall discuss in this assignment, 'Cognitive', the main theorist being, 'Piaget', (1896 - 1980), The, 'Psychosocial Theory', 'Erikson', (1902 - 1994), and, The 'Psychosexual', of, 'Freud', (1856 - 1939).

Psychology is a broad field that includes a wide variety of career opportunities. Some of these careers include health psychology, clinical psychology, sport psychology, and school psychology, only to mention a few. In this expansive field with much to offer, developmental psychology consists of just one of the many options available to psychologists. Developmental psychologists study the “social, cognitive, and physiological development during any of the following life stages: infancy, childhood, adolescence, and adulthood” (PsychologyCareerCenter). They also study the various landmarks associated in that particular age range (American Psychological Foundation). For example, a developmental psychologist who works with children might focus on developmental disabilities or behavioral problems in young children. One who works with aging adults might concentrate on the effects of Alzheimer’s or dementia on the mind (American Psychological Foundation).

Developmental Psychology is the ways that people change throughout their lifespan. Studies include the psychological affects, physical and social growth, intellectual, emotional and perceptual changes that occur. Developmental Psychology focus on a wide range of behavior changes beginning with prenatal development. Developmental Psychology also focuses on developmental disabilities and the effects it might have on people’s behavior. As with many fields related to psychology, a developmental psychologist must obtain a doctorate for most positions; some positions at the university level requires a PhD.

Many advances in cognitive development are seen throughout early childhood. Both Piaget and Vygotsky contribute theories which attempt to explain the background and development of these

Most of the criticism of Piaget’s work is in regards to his research methods. A major source of his inspiration for the theory was based on his observations of his own children. And because of this small sample group, people believe that it is difficult and incorrect to generalise his findings to a larger population. Similarly, many psychologists believe that Piaget underestimated the age which children could accomplish certain tasks and that sometimes children understand a concept before they are able to demonstrate their understanding of it. For example, children in the Sensorimotor stage may not search for a hidden object because their motor skills are not developed, rather than because they lack object permanence. This has been supported by evidence from Bower & Wishart (1972). They found that the way that an object is made to disappear influences the child’s response. As well as this, Piaget’s theory has been said to overestimate that every child and adult reaches the formal operational stage of knowledge development. Dasen (1994) claims that only a third of adults ever reach this stage.

According to Cliff Notes, Developmental psychology is the scientific study of age-related changes throughout the human life span. A discipline of scientific inquiry, developmental psychology recognizes humans of all societies and cultures as beings who are “in process,” or constantly growing and changing. This discipline identifies the biological, psychological, and social aspects that interact to influence the growing human life-span process. Within the last 25 years, developmentalist’s researchers who study human development expanded their focus to include the study of the physical, motor, cognitive, intellectual, emotional, personality, social, and moral changes that occur throughout all stages of the life span (cliff notes).

Development psychology refers to the scientific study of the systematic psychological changes that normally occur to human beings throughout their growth period from birth to old age. It was originally concerned with children and infants, but it has since expanded to include the entire life span of mankind including adolescence and adulthood. Development psychology covers the extent to which human development occurs through gradual accumulation of knowledge, and the extent to which children born with inmate mental structures learn through experience. Several psychological theories and approaches like the behavioral, humanistic, psychoanalytic, biological, and cognitive approaches have been developed to explain the

Jean Piaget is considered to be very influential in the field of developmental psychology. Piaget had many influences in his life which ultimately led him to create the Theory of Cognitive Development. His theory has multiple stages and components. The research done in the early 1900’s is still used today in many schools and homes. People from various cultures use his theory when it comes to child development. Although there are criticisms and alternatives to his theory, it is still largely used today around the world.

Next, the "pre-operational stage" is the second stage of Piaget’s theory. This stage lasts from around 2 - 7 years. In this stage, Piaget proposed that a child fails to understand the concept “conservation” - the belief that things remain constant in terms of number, quantity and volume irrespective of variations in appearance. In experiments to test number conservation, Piaget showed the child two sets of checkers, which had exactly the same number of checkers in each set. He then changed one of the checker sets, keeping the same amount of checkers in it, so that it was only different in appearance. When the experiment ended, the results showed that the children believed that the sets were of different quantity, thereby, proving Piaget’s theory factual. (Piaget 1952)

For the purpose of this paper, I will replicate the conservation tasks experiment to test Piaget’s theories. My test subject is a five year old girl named Truphena, she -according to Piaget-is categorized to be in the pre-operational stage of intellectual development. Therefore she wouldn’t be expected to succeed at the conservation tasks that will be presented to her. I also have another subject named Franklin who is nine year old, he

Educational Implications of Piaget’s Theory. Piaget’s theory of cognitive development is well-known and provides a basic understanding of the cognitive process and how children

Week one started off with developmental psychology, which is defined as identifying and explaining the continuities and changes individuals display over time. There are two ways that cause humans to develop, these are by maturity and learning experiences. A person that observes developmental psychology are known as developmentalist.
