Repressed memories are hypothesized memories having been unconsciously blocked, due to the memory being associated with a high level of stress or trauma. The theory postulates that even though the individual cannot recall the memory, it may still be affecting them consciously.〔(Questions and Answers about Memories of Childhood Abuse )〕 The existence of repressed memories is a controversial topic in psychology; some studies have concluded that it can occur in victims of trauma, while others dispute it. According to some psychologists, repressed memories can be recovered through therapy. Other psychologists argue that this is in fact rather a process through which false memories are created by blending actual memories and outside influences. Furthermore, some psychologists believe that repressed memories are a cultural symptom because there is no written proof of their existence before the nineteenth century. According to the American Psychological Association, it is not possible to distinguish repressed memories from false ones without corroborating evidence.〔 The term repressed memory is sometimes compared to the term dissociative amnesia, which is defined in the DSM-IV as “an inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness”. Amnesia is referred to any instance in which memories stored in the long-term memory are completely or partially forgotten, usually due to brain injury. According to proponents of the existence of repressed memories, such memories can be recovered years or decades after the event, most often spontaneously, triggered by a particular smell, taste, or other identifier related to the lost memory, or via suggestion during psychotherapy. == History == There is no documented writing about repressed memories or dissociative amnesia (as it is sometimes referred to), before the 1800s.〔Pope H., et al. Psychol. Med., 37. 225 - 233 (2007).〕 The concept of repressed memory originated with Sigmund Freud in his 1896 essay ''Zur Ätiologie der Hysterie'' ("On the etiology of hysteria").〔 〕 One of the studies published in his essay involved a young woman by the name of Anna O. Among her many ailments, she suffered from stiff paralysis on the right side of her body. Freud stated her symptoms to be attached to psychological traumas. The painful memories had separated from her consciousness and brought harm to her body. Freud used hypnosis to treat Anna O. She is reported to have gained slight mobility on her right side. Freud's repressed memory theory joined his philosophy of psychoanalysis. Repressed memory has remained a heavily debated topic inside of Freud's psychoanalysis philosophy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「repressed memory」の詳細全文を読む スポンサード リンク
