7. There are three major theories of personality: Freudian theory, neo-Freudian theory, and trait
theory.
a) Freudian theory: Sigmund Freud’s psychoanalytic theory of personality is one of the
cornerstones of modern psychology.
i) This theory was built on the premise that unconscious needs or drives, especially
biological and sexual drives, are at the heart of human motivation and personality.
ii) Freud proposed that the human personality consists of three interacting systems: the
id, the superego and the ego.
a) The id is the “warehouse” of primitive and impulsive drives, such as: thirst,
hunger, and sex, for which the individual seeks immediate satisfaction
without concern for the specific means of that satisfaction.
b) The superego is the individual’s internal expression of society’s moral and
ethical codes of conduct.
(1) The superego’s role is to see that the individual satisfies needs in a
socially acceptable fashion.
