One of the most influential and famous psychologists named Jean Piaget has given his theory on cognitive development in which he has mentioned four distinct stages including sensorimotor, preoperational, concrete operational, and formal-operational.

Formal-operational stage: According to Piaget's theory, the formal-operational stage is last i.e the fourth stage. This stage generally starts at the age of twelve years of a child and lasts through adulthood.
