Answer: Superego
Explanation:
According to Sigmund Freud's theory, superego develops between the ages of five. At this age, children learn from their parents and important authorities in the society. Children learn what is morally good, acceptable and justified from parents and important authorities in their lives. Superego is of two types which are: the ego ideal and the conscience.
The ego ideal deals with rules for morally good behaviors which are accepted by parents and significant authority figures. Children feel happy whenever these behaviors are been exhibited by them.
The conscience deals with rules for bad behaviors which makes children to be filled with regret whenever they exhibit these behaviors or do something bad.
