Piaget's theory of cognitive development
Piaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence, first developed by Swiss developmental psychologist Jean Piaget (1896–1980). It is primarily known as a developmental stage theory but, in fact, it deals with the nature of knowledge itself and how humans come gradually to acquire, construct, and use it. To Piaget, cognitive development was a progressive reorganization of mental processes as a result of biological maturation and environmental experience. Accordingly, children construct an understanding of the world around them, then experience discrepancies between what they already know and what they discover in their environment. Moreover, Piaget claimed the idea that cognitive development is at the center of human organism, and language is contingent on cognitive development. Nature of intelligence: operative and figurative Operative intelligence is the active aspect of intelligence.
