Cognitive Development

A large portion of research has gone into understanding cognitive Development a child perceives it’s world. Jean Piaget was a major force establishing this field, forming his “theory of cognitive development”. Many of Piaget’s theoretical claims have since fallen out of favor.

Perhaps equally importantly, Piaget identified and described many cognitive changes that must be explained, such as object permanence in infancy and the understanding of logical relations and cause-effect reasoning in school age children. The many phenomena he described still attract the interest of many current researchers. Cognitive development and motor development may also be closely interrelated. When a person experience a neurodevelopmental disorder and their cognitive development is disturbed, we often see adverse effects in motor development as well.

Historical origins: The history and theory of cognitive development. Jean Piaget is inexorably linked to cognitive development. It is clear that in Piaget’s writings that there are influences from many historical predecessors. A few that are worth mentioning are included in the following Historical Origins chart.

Conti-Ramsden 2004

He discusses childhood development as happening in three stages. First stage, up to age 12, the child is guided by their emotions and impulses. 16, the child’s reason starts to develop. The third and final stage, age 16 and up, the child develops into an adult. He used a detailed observational study method with the children. Area of specialty was developmental psychology.

ZPD is the link between children’s learning and cognitive development. Began her career working with mentally disabled children in 1897, then she conducted observation and experimental research in elementary schools. Discussed the Four Planes of Development. 6, 6 -12, 12 -18, and 18 -24. The Montessori Method now has three developmentally-meaningful age groups.

Piaget was the first psychologist and philosopher to brand this type of study as “cognitive development”. Other researchers, in multiple disciplines, had studied development in children before, but Piaget is often credited as being the first one to make a systematic study of cognitive development and gave it its name. His main contribution is the stage theory of child cognitive development. Wrote the theory of stages of moral development which extended Piaget’s findings of cognitive development and showed that they continue through the lifespan.

Kohlberg’s 6 stages follow Piaget’s constructivist requirements in that stages can not be skipped and it is very rare to regress in stages. The first stage in Piaget’s stages of cognitive development is the sensorimotor stage. This stage lasts from birth to two years old. During this stage, behaviors lack a sense of thought and logic.

Behaviors gradually move from acting upon inherited reflexes to interacting with the environment with a goal in mind and being able to represent the external world at the end. The sensorimotor stage has been broken down into six sub stages that explain the gradual development of infants from birth to age 2. Once the child gains the ability to mentally represent reality, the child begins the transition to the preoperational stage of development. Each child is born with inherited reflexes that they use to gain knowledge and understanding about their environment. Examples of these reflexes include grasping and sucking. Children repeat behaviors that happen unexpectedly because of their reflexes. For example, a child’s finger comes in contact with the mouth and the child starts sucking on it.

Music, Rhythm, and Dance

If the sensation is pleasurable to the child, then the child will attempt to recreate the behavior. Child has an experience with an external stimulus that they find pleasurable, so they try to recreate that experience. For example, a child accidentally hits the mobile above the crib and likes to watch it spin. When it stops the child begins to grab at the object to make it spin again.

In this stage habits are formed from general schemes that the infant has created but there is not yet, from the child’s point of view, any differentiation between means and ends. Behaviors will be displayed for a reason rather than by chance. They begin to understand that one action can cause a reaction. They also begin to understand object permanence, which is the realization that objects continue to exist when removed form view. For example: The baby wants a rattle but the blanket is in the way.

Actions occur deliberately with some variation. For example a baby drums on a pot with a wooden spoon, then drums on the floor, then on the table. Children begin to build mental symbols and start to participate in pretend play. For example, a child is mixing ingredients together but doesn’t have a spoon so they pretend to use one or use another object the replace the spoon. Lasts from 2 years of age until 6 or 7.

It can be characterized in two somewhat different ways. In his early work, before he had developed his structuralist theory of cognition, Piaget described the child’s thought during this period as being governed by principles such as egocentrism, animism and other similar constructs. Egocentrism is when a child can only see a certain situation his or her own way. Lasts from 6 or 7 years until about 12 or 13. During this stage the child’s cognitive structures can be characterized by reality. Piaget argues that the same general principles can be discerned in a wide range of behaviors.

One of the best-known achievements of this stage is that of conservation. Lasts from 12 or 13 until adulthood and are advancing from logical reasoning with concrete examples to abstract examples. The need for concrete examples is no longer necessary because abstract thinking can be used instead. In this stage adolescents are also able to view themselves in the future and can picture the ideal life they would like to pursue. Many of his claims have fallen out of favor. For example, he claimed that young children cannot conserve numbers. However, further experiments showed that children did not really understand what was being asked of them.

Empiricists study how these skills may be learned in such a short time. The debate is over whether these systems are learned by general-purpose learning devices, or domain-specific cognition. Moreover, many modern cognitive developmental psychologists, recognizing that the term “innate” does not square with modern knowledge about epigenesis, neurobiological development, or learning, favor a non-nativist framework. Infants appear to have two systems for dealing with numbers.

One deals with small numbers, often called subitizing. Another deals with larger numbers in an approximate fashion. Very young children appear to have some skill in navigation. This basic ability to infer the direction and distance of unseen locations develops in ways that are not entirely clear. However, there is some evidence that it involves the development of complex language skills between 3 and 5 years. One of the original nativist versus empiricist debates was over depth perception.

There is some evidence that children less than 72 hours old can perceive such complex things as biological motion. A major, well-studied process and consequence of cognitive development is language acquisition. The traditional view was that this is the result of deterministic, human-specific genetic structures and processes. Other traditions, however, have emphasized the role of social experience in language learning.

It wasn’t until recently that bilingualism had really been accepted as a contributing factor to cognitive development. Ellen Bialystok, was, and is a big game changer in this field. Bialystok has done years of research on the effects bilingualism has on cognitive development. There have been a number of studies showing how bilingualism contributes to the executive function of the brain, which is the main center at which cognitive development happens. Edward Sapir, posited that a person’s thinking depends on the structure and content of their social group’s language. In other words, it is the belief that language determines our thoughts and perceptions. Neo-Piagetian theories of cognitive development emphasized the role of information processing mechanisms in cognitive development, such as attention control and working memory.

They suggested that progression along Piagetian stages or other levels of cognitive development is a function of strengthening of control mechanisms and enhancement of working memory storage capacity. During development, especially the first few years of life, children show interesting patterns of neural development and a high degree of neuroplasticity. Neuroplasticity, as explained by The World Health Organization, can be summed in three points. Any adaptive mechanism used by the nervous system to repair itself after injury.

From cultural psychologists’ view, minds and culture shape each other. In other words, culture can influence brain structures which then influence our interpretation of the culture. Behavioral research has shown that one’s strength in independent or interdependent tasks differ based on their cultural context. In general, East Asian cultures are more interdependent whereas Western cultures are more independent.
