Psychoanalysis is a lengthy insight therapy developed by Freud that aims to uncover unconscious conflicts through techniques like free association and dream analysis. It views human behavior as resulting from interactions between the id, ego, and superego. The goal of psychoanalysis is to help patients understand their unconscious motivations by becoming aware of unresolved conflicts driving their behaviors. Techniques include free association, dream analysis, and interpretation by the therapist to provide insight and allow new ways of coping with anxiety and guilt.
