Unconscious

Unconscious, in psychology, that part of the mind the individual is unable to recall at will. The concept of the unconscious, or subconscious, was developed and studied by Sigmund Freud, the founder of psychoanalysis. He believed the unconscious included instinctual drives and repressed memory and desires. To this foundation of belief, C.G. Jung added the idea that there is also a collective unconscious, universal or cultural mental patterns and acts.
