Repressed memory is a term used to describe a significant memory, usually of a traumatic nature that has become unavailable for recall due to a psychogenic mechanism. The term is somewhat of a misnomer because it is often used to describe memories that have been dissociated from awareness as well as those pushed from awareness (i.e., repression) entirely without dissociation. Although there has been much debate on the topic of repressed memories in the media and public arena, studies consistently demonstrate that amnesia occurs in survivors of trauma.[1][2][3][4][5] Repressed memories may sometimes 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 rarely, via suggestion during psychotherapy.[6]

[edit] Overview
The theory of dissociative amnesia makes the assumption that memory repression is possible. Linda Williams conducted a study to determine whether women who had been sexually assaulted as children could all remember the abuse. The women had been taken to hospital as children as reported victims of sexual abuse. Between 15 and 18 years later, the women were interviewed and 38% did not report that particular incident. Williams noted that many of these women did disclose other very personal events and other incidents of sexual assaults.[7] Some peer reviewed and clinical studies (including ones cited by the Leadership Council) continue to support the existence of recovered memory. [8][9] One source lists over one hundred corroborated cases of recovered memory in legal, clinical and scientific case studies. [10]In one overview of research findings, it was found that those reporting severe amnesia ranged from under 12% to 59% percent of child abuse survivors. [11]The same study found that 31 to 64 percent of abuse survivors in six major studies stated they forgot "some of the abuse."[11]Furthermore, studies reported 50 to 75% of abuse survivors being able to corroborate the facts about their abuse via an external source.[11]One in three female subjects failed to recall documented sexual abuse incidents 17 years after childhood sexual assault that led them to the emergency room.[12]One study documents a case of recovered memory of childhood trauma with documented sexual trauma in early childhood. It chronicled the evidence of the absence of memory for traumatic experience over time and then the substantial evidence of ‘spontaneous’ recovery of memory.[13]

The Leadership Council on Child Abuse & Interpersonal Violence asserts that Brown, Scheflin and Hammond in their book, "Memory, Trauma Treatment, and the Law" (New York: Norton, 1998) reviewed 43 studies and concluded that every study that examined the question of dissociative amnesia in traumatized populations demonstrated that a substantial minority partially or completely forgot the traumatic event experienced, and later recovered memories of the event. [14] One research project has documented thirty-five cases of recovered memories of traumatic childhood events which have been corroborated “by clear and convincing evidence.” [15]A study by Corwin and Olafson has videotaped a child’s disclosure of sexual abuse and eleven years later the spontaneous return of the reportedly unrecallable memory. [16]

Alan Scheflin, in a Psychiatric Times article states that science is limited on the issue of repressed memory. He concluded that on the basis of three relevant studies that repressed memories are "no more and no less accurate than continuous memories" and recommended that therapists and courts should consider these repressed memories the same as they consider regular memories. [17]

The Leadership Council on Child Abuse & Interpersonal Violence asserts: "Research has shown that traumatized individuals respond by using a variety of psychological mechanisms. One of the most common means of dealing with the pain is to try and push it out of awareness. Some label the phenomenon of the process whereby the mind avoids conscious acknowledgment of traumatic experiences as dissociative amnesia...there is near-universal scientific acceptance of the fact that the mind is capable of avoiding conscious recall of traumatic experiences." [18]Jennifer Freyd writes that Ross Cheit’s “case of suddenly remembered sexual abuse is one of the most well documented cases currently available for public scrutiny." [19]Cheit prevailed in two lawsuits, located five additional victims and tape-recorded a confession.[19]

It has been proposed in the Betrayal Trauma Theory that “that psychogenic amnesia is an adaptive response to childhood abuse” and that “victims may need to remain unaware of the trauma not to reduce suffering but rather to promote survival.”[20] The amnesia allows the child maintain attachment to a person that a child needs to depend on for survival and development.[20]

Harvard University's Richard McNally wrote that he considers the notion of repressed memory to be a "pernicious bit of psychiatric folklore" [21]. A recent Amicus Brief to the California Supreme Court drafted by R. Christopher Barden and signed by nearly 100 international experts in the field of human memory emphasized there is no credible scientific support for the notions of repressed and recovered memories. [22]

Researchers have stated that repression can operate on a social level as well.[23]Judith Herman stated that “The knowledge of horrible events periodically intrudes into public awareness but is rarely retained for long."[23]


[edit] Body memory
Main article: Body memory
Body memory is supposed to be a form of repressed memory. Body memory is a claim that the body itself (rather than the brain) remembers something - typically abuse. This is characterized by a pain in a body part where there appears to be no present-day physical reason for the pain, thus this is seen as evidence of the body remembering a past pain, similar to phantom limb syndrome.[citation needed]

Some psychologists and social workers use the term body memory to refer to physical symptoms that accompany trauma[citation needed]. Studies have shown that survivors of trauma, specifically with PTSD, have a predisposition to illness and injuries because stress weakens the immune system [24], but this stress-related vulnerability to illness is a completely different idea than memories stored and repressed within non-brain tissue.


[edit] Legal issues
The fact that the concept of repressed memory appears in the DSM-IV shows that this concept is 'relevant in the specific scientific community', according to a 1993 legal precedent often simply referred to as Daubert. This meant that during the 1990s, in some jurisdictions, this satisfied court rules regarding the admissibility of scientific testimony as court evidence. It should be noted however that since that time, the law has subsequently evolved, and has to some extent been shaped, by the controversy over recovered memories. The way it has responded varies according to the legal system of the state or country concerned. So in recent years, sometimes recovered memories may or may not be presented as evidence, depending on the court. [25]. In some jurisdictions, specific guidelines have been put in place. For example, a New Hampshire state law, known as the Hungerford Law, places strict limitations on the way repressed and recovered memories are admitted in court; in some cases preventing it altogether[26].

Some criminal cases have been based on a witness' testimony of recovered repressed memories, often of alleged childhood sexual abuse. In some jurisdictions, the statute of limitations for child abuse cases has been extended to accommodate the phenomena of repressed memories as well as other factors. The repressed memory concept came into wider public awareness in the 1980s and 1990s; followed by a reduction of public attention after a series of scandals, lawsuits, and license revocations.[27]

In a 1996 ruling, the US District Court found that "the reliability of the phenomenon of repressed memory has been established, and therefore, will permit the plaintiff to introduce evidence which relates to the plaintiff's recovered memories". Judge Harrington cited DSM-IV, 1994, writing that "American Psychiatric Association, also recognizes the concept of repressed memories", and in the concluding paragraph of the decision wrote: "It is important to stress that, in considering the admissibility of repressed memory evidence, it is not the role of the Court to rule on the credibility of this individual plaintiff's memories, but rather on the validity of the theory itself. For the foregoing reasons, the Court hereby denies the Defendant's Motion in Limine to Exclude Repressed Memory Evidence."[28]


[edit] Recovered memory therapy
Main article: Recovered memory therapy
Recovered memory therapy (RMT) is a term coined by affiliates of the False Memory Syndrome Foundation (FMSF) in the early 1990s,[29][30][31] to refer what they described as a range of psychotherapy methods based on recalling memories of abuse that had previously been forgotten by the patient.[32] The term is not listed in DSM-IV or used by any mainstream formal psychotherapy modality.[29]

Kenneth Pope, during an award address for the American Psychological Association's Award for Distinguished Contributions to Public Service, stated that the false memory movement may have affected treatment and diagnosis and access to services for some clients.[33]

Brown, Scheflin and Hammond in their book argue that "Occasional suggestions about abuse are not generally effective." They assert that the idea that suggesting false memories in therapy can create false memories has not been tested. [34] Charles Whitfield, MD, in his 1995 book Memory and Abuse, states that all critics of studies of the studies showing support for the validity of delayed memories, that he had found, are members of the False Memory Syndrome Foundation advisory board.[35].

A 1998 working group and literature review paper in the British Journal of Psychiatry reported it found "vast literature but little acceptable research" on this controversy.[36] The report stated that the use of "extraordinary means" to recover memories resulted in a high probability of memories of incidents that had not occurred, but that the question of memories that might be false or recovered "should not be allowed to confuse the recognition and treatment of sexually abused children". [36]

Even when patients who decide their recovered memories are false and retract their claims can suffer post traumatic stress disorder due to the effects what they believe are false memories, due to what some therapists call a "brain stain".[37]


[edit] History
The concept was originated by Sigmund Freud in his 1896 essay Zur Ätiologie der Hysterie ("On the etiology of hysteria"), however Freud himself abandoned his theory between 1897-1905, and during 1920-1923 replaced it with his impulse-based concept of Id, Super-ego, and Ego. Friedrich Nietzsche was the first to suggest an active, conscious thought management method in the second essay of his On the Genealogy of Morals as a necessary fundament of efficiency, responsibility, and maturity.
