Cognitive development is the term used to describe the construction of thought process, including remembering, problem solving and decision-making, from childhood through adolescence to adulthood. In this essay I will compare and contrast the theories of Piaget and Vygotsky, both of which were enormously significant contributors to the cognitive development component to/in psychology. In addition to this I will also weigh up the strengths and weaknesses of each theory and outline how they can be applied to an educational setting.
At the centre of Piaget's theory is the principle that cognitive development occurs in a series of four distinct, universal stages, each characterized by increasingly sophisticated and abstract levels of thought. He believed that these stages always occur in the same order, each builds on what was learned in the previous stage and that the development resulted from two influences: maturation and interaction with environment. Although Vygotsky’s theory works along similar lines to Piaget – the belief that children were active in their learning. He focused more on the importance of social interaction and language and how they both play a fundamental influence on children’s development of understanding. Although both psychologists acknowledged that all children go through stages, they were distinguished by different styles of thinking, and approach to analysing the cognitive development process. The stages were the centre of Piaget’s theory while Vygotsky only acknowledged them in his theory.
Piaget’s theory unlike Vygotsky, generalized children into age groups and ranked their abilities accordingly. For example: Piaget believed that all children that reach The concrete Operational stage (ages 7-11) have overcome centration and become decentred, they are capable of mastering the principles of classification, seriation and class inclusion. However, Vygotsky maintained the concept that if a child follows the adult's
