repressed memory repressed memory repressed memory is an alleged psychiatric phenomenon which involves an inability to recall autobiographical information, usually of a traumatic or stressful nature. the concept originated in psychoanalytic theory where repression is understood as a defense mechanism that excludes painful experiences and unacceptable impulses from consciousness. repressed memory is a controversial concept, particularly in legal contexts where it has been used to impugn individuals unfairly and inaccurately, leading to substantial harm. at the same time, an american psychological association working group indicated that while "most people who were sexually abused as children remember all or part of what happened to them, it is possible for memories of abuse that have been forgotten for a long time to be remembered". although sigmund freud later revised his theory, he initially held that memories of childhood sexual trauma were often repressed (could not be recalled later in life) yet the traumas unconsciously influenced behavior and emotional responding.
