Strengths And Weaknesses Of Piaget

Brief History
Jean Piaget was a Twentieth century Swiss psychologist and was the first psychologist to systematically study the cognitive development of children. Thomas (2005) wrote that early in Piaget’s career he worked with children and his observations and interactions with the students led him to the theory that a young person's cognitive processes are inherently different from those of adults (pp. 188-9).

Furthermore, most of his research subjects were from a middle-class background, so therefore he failed to take into consideration children from other backgrounds. Finally, his theory only focuses on children who follow normal development and he does not account for children experiencing adolescence or who are impaired (pp.
