When looking at why a person chooses to behave a particular way, i will examine what happened in childhood and what kinds of issues the patient is conscious of?

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;
