Jean Piaget

Jean Piaget was a child psychologist and theorist who formed the theory of cognitive development. Piaget’s cognitive development theory has four cognitive stages. He described the cognitive development stages to relate a person’s ability to understand and acquire new information. His cognitive development stages are the sensorimotor, preoperational, concrete operational and formal operational stage.
I think others should not criticize Piaget’s cognitive development theory because he wants others to know how the mind works. Everyone should appreciate or admire his work rather than criticize his theories. His theory describes how the mind can process new information in the four stages of development. He focused on children’s thinking more than how a stimulus influenced children’s behavior. Cognitive is defined as thinking, remembering, reasoning or using language. Piaget’s major contribution was the idea of a scheme. He thinks that children build a different kind scheme as they develop from childhood to adulthood.
According to Piaget, there are age differences amongst children from childhood to adolescence. He believes that all children seem to follow the same sequence of discoveries, making the same mistakes and arriving at the same answers. I believe Piaget was right that there is a pattern for children making the same wrong answers. Piaget discovered that all three or four year olds seem to think alike. All three or four year olds think that if water is poured from a wide glass into a narrower one, then there is more water. The children think that the amount of water has changed because water is poured into another glass. Compared to seven year olds, they can realize that the amount of water has not changed when water is poured into another glass.
