Free association is a psychological technique used in therapy, particularly in psychoanalysis. It involves patients speaking freely about their thoughts, feelings, and memories without censorship. This method helps uncover unconscious thoughts and emotions that may be influencing behavior. During free association, a therapist encourages the patient to express whatever comes to mind, no matter how trivial or unrelated it may seem. This process can reveal patterns and connections that provide insight into the patient's psyche, aiding in the understanding and treatment of mental health issues.
