Discuss the origin and application of psychoanalysis.

Psychoanalysis was developed by Sigmund Freud and was the first form of psychotherapy. It was the dominant therapeutic technique in the early 20th century, but it has since waned significantly in popularity. Freud believed most of our psychological problems are the result of repressed impulses and trauma experienced in childhood, and he believed psychoanalysis would help uncover long-buried feelings. In a psychoanalyst's office, you might see a client lying on a couch speaking of dreams or childhood memories, and the therapist using various Freudian methods such as free association and dream analysis.
