Erick Erickson was a neo-Freudian. he was a social cognitive psychologist who took Freud's controversial theory on psycho-sexual stages theory. He emphasized that psycho-sexual stages such as ego make a positive contribution to development by mastering attitude, ideas, and skills at each stage of development. This mastery helps the children to grow successful, contributing members of society. During each stage of psycho-social theory stages, there are psycho-sexual conflicts that must be successfully overcome for a child to develop into a healthy and well adjusted young adult. If the failure occurs to these mastery leads to inadequacy in life or crisis in adulthood.
