Jean PiagetPiaget's theory of cognitive development is a comprehensive theory about the nature and development of human intelligence, first developed by Jean Piaget. 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. Children construct an understanding of the world around them, then experience discrepancies betweenwhat they already know and what they discover in their environment.
