Answer: Psychoanalysis.
Step-by-step explanation:
Sigmund Freud (1856 – 1939) was the founder of the Psychoanalytic approach, which examines unconscious impulses to explain human behavior. Freud maintained that the mind had both conscious and unconscious thoughts, developed based on psychic forces, and trauma could be cured by transforming unconscious thoughts and motivations into conscious ideas, therefore providing insight.
