This review will briefly look at the theories of Jean Piaget and Jerome Bruner and visit how these two theorists thought about cognition (cognition refers to thinking and memory processes) and cognitive development (cognitive development refers to long-term changes in these processes.)
Both Piaget and Bruner were interested in cognitive development. Both developed their own cognitive theories of development.
Piaget is best known for his cognitive stage theory, in which he maintains that children and youth gradually become able to think logically and scientifically in distinct stages. And this through two processes called accommodation and assimilation, and subsequent equilibration which interplay to construct mental representations of objects and experiences. These mental models of the world are then created and held in mental schema. Piaget, because of his background in Psychology, refers to development, not learning per se.
Bruner is best known for his spiral curriculum, for his emphasis on revisiting learning, on discovery learning and for his belief that language, not only encoded and mediated language, but that it allowed cognition to reach higher levels (making possible the generation of new propositions).
