From 1925 to 1929 Piaget was a professor at the University of Neuchâtel, and in 1929 he joined the faculty of the University of Geneva as professor of child psychology, remaining there until his death.
Theory of Moral Development
According to Jean Piaget children between the ages of 5 to 10 years see the world through the lens of a "heteronomous" (other-directed) morality. They adhere to the regulations and rules of their parents to avoid being punished. At the end of midddle childhood the children's appreciation becomes more autonomous (self-directed).
