Psychoanalysis is a method of studying the human mind and human behaviour in order to better understand psychological functioning and improve emotional well-being. Perhaps the most important principle of psychoanalysis is that unconscious factors play a major role in people's lives and that the psychoanalyst needs to address those factors to treat an emotional disorder. For example, an individual who as a child witnessed her parents' divorce may, unwillingly, have problems forming a satisfactory relationship as a grown-up. Psychoanalysis could help such a person by allowing her to revisit the divorce of her parents, becoming conscientiously aware that her own personal life need not repeat the family life of her mother or father.
