Psychoanalysis can be used here. Psychoanalysis is a set of theories and therapeutic techniques connected to the study of the unconscious mind, which together form a process of treatment for mental-health disorders. The basic views of psychoanalysis include:
- a person's growth is determined by frequently forgotten events in early childhood, rather than by inherited traits alone;
- human behavior and cognition are mainly determined by unreasonable drives that are deep-rooted in the unconscious;
- efforts to bring those drives into consciousness triggers resistance in the form of defense mechanisms, chiefly repression;
- conflicts between conscious and unconscious material can effect in mental disturbances for instance anxiety and depression;
- unconscious material can start in dreams and unintentional acts, comprising mannerisms and slips of the tongue;
