This document summarizes key aspects of the psychoanalytic perspective on personality as proposed by Sigmund Freud. It describes Freud's theory that personality is formed by unconscious drives and conflicts between the id, ego, and superego. Freud believed people progress through psychosexual stages in early childhood and that experiences at these stages can result in fixation. The Oedipus complex and its resolution are also explained. The document briefly discusses some criticisms from neo-Freudian theorists like Jung, Horney, and Adler.
