What is jean piaget known for?

Answer 1

Jean Piaget was a French psychologist who is known for the developmental stages he created from studies he did based on the development of his own children. From this he created four stages of development that he assumed most children went through. These stages were: the sensorimotor stage (from birth to age two: the child learns to use each of their 5 senses), the Preoperational stage (ages 2-7. this is the age were children tend to believe things to be animated, such as the belief in imaginary friends or that planes fly by magic. Logical thinking is not very strong in this stage and they tend to be egocentric), the Concrete Operational stage (ages 7-12; the child begins to think more logically, but their thought are not very flexible. They are less egocentric), and finally, the Formal Operations stage (from age 12 on; the child can now think logically and begin abstract thought).
