Resistance (psychoanalysis)
In psychoanalysis, resistance is the individual's efforts to prevent repressed drives, feelings or thoughts from being integrated into conscious awareness. Sigmund Freud, the founder of psychoanalytic theory, developed the concept of resistance as he worked with patients who suddenly developed uncooperative behaviors during the analytic session.
