Psychoanalysis
Psychoanalysis is a theory of mind and a method of psychological treatment originating in the 1890s with the work of Austrian physician Sigmund Freud. It emphasizes unconscious mental processes, conflict, and symbolic meaning, employing techniques such as free association, dream interpretation, and analysis of transference in intensive, multi‑session therapeutic settings. The field subsequently diversified into multiple schools and institutions and remains the subject of ongoing empirical evaluation and philosophical debate.
