Answer:
Piaget’s theory of cognitive development is a comprehensive theory about the nature and development of human intelligence. Piaget believed that one’s childhood plays a vital and active role in a person’s development.[1] Piaget’s idea is primarily known as a developmental stage theory. The theory deals with the nature of knowledge itself and how humans gradually come to acquire, construct, and use it.[2] To Piaget, cognitive development was a progressive reorganization of mental processes resulting from biological maturation and environmental experience. He believed that children construct an understanding of the world around them, experience discrepancies between what they already know and what they discover in their environment, then adjust their ideas accordingly.[3] Moreover, Piaget claimed that cognitive development is at the center of the human organism, and language is contingent on knowledge and understanding acquired through cognitive development.[4]
