Definition: http://dynamic.uoregon.edu/~jjf/whatabout.html What about Recovered Memories? Jennifer J. Freyd, University of Oregon “Sivers, Schooler, and Freyd (2002, p 169) define recovered memory as “The recollection of a memory that is perceived to have been unavailable for some period of time.”

Memory disturbances and dissociative amnesia in Holocaust survivors http://blogs.brown.edu/recoveredmemory/scholarly-resources/holocaust/
The following articles provide compelling scientific evidence in support of the phenomena of dissociation and recovered memory in Holocaust survivors. In addition to supporting the phenomenon in general, these articles also counter the argument that recovered memory is (a) no more than a recent cultural “fad” and (b) specific to false accusers of sexual abuse.
http://blogs.brown.edu/recoveredmemory/about/ Can traumatic events be forgotten…and then remembered later in life? “This debate has focused on recovered memories of childhood sexual abuse. But the phenomenon extends to other traumas, such as suffering physical abuse or witnessing a murder. Almost everyone would agree that such traumas are normally remembered. That is, most people who experience such a trauma are likely to remember it, perhaps vividly and instrusively. But do some people forget completely? A variety of scientific sources say “yes.”

http://www.jimhopper.com/memory/ Recovered Memories of Sexual Abuse Scientific Research & Scholarly Resources by Jim Hopper “Amnesia for childhood sexual abuse is a condition. The existence of this condition is beyond dispute. Repression is merely one explanation – often a confusing and misleading one – for what causes the condition of amnesia. At least 10% of people sexually abused in childhood will have periods of complete amnesia for their abuse, followed by experiences of delayed recall.”
http://www.leadershipcouncil.org/1/tm/tm.html 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 . Others use terms such as repression , dissociative state , traumatic amnesia, psychogenic shock, or motivated forgetting . Semantics aside, there is near-universal scientific acceptance of the fact that the mind is capable of avoiding conscious recall of traumatic experiences.
How often do children’s reports of abuse turn out to be false? Research has consistently shown that false allegations of child sexual abuse by children are rare. Jones and McGraw examined 576 consecutive referrals of child sexual abuse to the Denver Department of Social Services, and categorized the reports as either reliable or fictitious. In only 1% of the total cases were children judged to have advanced a fictitious allegation. Jones, D. P. H., and J. M. McGraw: Reliable and Fictitious Accounts of Sexual Abuse to Children.Journal of Interpersonal Violence, 2, 27-45, 1987. In a more recent study, investigators reviewed case notes of all child sexual abuse reports to the Denver Department of Social Services over 12 months. Of the 551 cases reviewed, there were only 14 (2.5%) instances of erroneous concerns about abuse emanating from children. These consisted of three cases of allegations made in collusion with a parent, three cases where an innocent event was misinterpreted as sexual abuse and eight cases (1.5%) of false allegations of sexual abuse.

Therapy for adults molested as children by John Briere “It is my clinical impression, supported by a growing body of research, that many (although not all) survivor reports of previously unavailable abuse memories represent actual occurrences. To the extent that this is true, there exists a certain unpleasant irony: By negating true accounts of sexual abuse, our culture may be accomplishing exactly what it discounts in the survivor: “Repressing” or wishing away things that are too painful to tolerate in conscious awareness.” p. 48 – Springer Publishing Company, 1996 ISBN 082615641X, 9780826156419, 256 pages http://books.google.com/books?id=tyz0GlsdxiUC

Synopsis of data from “Memory, Trauma Treatment, and the Law” by Brown, Scheflin and Hammond, W.W. Norton and Co. New York and London, C 1998 (http://www.wwnorton.com) Page 370-381
The base rates for memory commission errors are quite low, at least in professional trauma treatment. The base rates in adult misinformation studies run between zero and 5 percent for adults and between 3 – 5 percent for children.
“Occasional unwitting misleading suggestions (Yapko, 1994a), even the suggestion of a diagnosis of abuse, cannot adequately explain illusory memories of child sexual abuse.” (p. 379)
It is almost totally impossible for anyone to make a memory error for the central plot of a memory simply by hearing disinformation. A variety of other factors would have to be in place. Even under hypnosis without several social influence factors, it is extremely rare (4-6% of 7-10%, less than one percent of people) may be influenced by disinformation.
Memory on Trial – Research suggests that children’s memory may be more reliable than adults’ in court cases ...3/6/08 The U.S. legal system has long assumed that all testimony is not equally credible, that some witnesses are more reliable than others. In tough cases with child witnesses, it assumes adult witnesses to be more reliable. But what if the legal system had it wrong? Researchers Valerie Reyna, human development professor, and Chuck Brainerd, human development and law school professor — both from Cornell University — argue that like the two-headed Roman god Janus, memory is of two minds — that is, memories are captured and recorded separately and differently in two distinct parts of the mind. They say children depend more heavily on a part of the mind that records, “what actually happened,” while adults depend more on another part of the mind that records, “the meaning of what happened.” As a result, they say, adults are more susceptible to false memories, which can be extremely problematic in court cases. Reyna’s and Brainerd’s research, funded by the National Science Foundation, Arlington, Va., sparked more than 30 follow-up memory studies, many of them also funded by NSF. The researchers review the follow-on studies in an upcoming issue of Psychological Bulletin….Reyna and Brainerd’s findings are summarized in a new book, The Science of False Memory, published by Oxford University Press. http://www.nsf.gov/news/news_summ.jsp?cntn_id=111230&org=NSF&from=news?
“Forgetting and Recovering the Unforgettable.” Psychological Science – Volume 19, Number 5 – May 2008 Steven M. Smith & Sarah C. Moynan “Some experiences, particularly those that are emotional and distinctive, may seem unforgettable. Can memories of emotional and distinctive events be blocked from consciousness, and if so, can those memories subsequently be recovered? Although there is considerable laboratory research demonstrating false memories, relatively few studies have examined blocked and recovered memories, as we did in the study reported in this article. As noted in reviews by Gleaves, Smith, Butler, and Spiegel (2004) and by Roediger and Bergman (1998), the false-memory debate must be informed by experimental laboratory research examining not only false memories, but also blocked and recovered memories….In the present study, we investigated whether interference can cause dramatic forgetting that is subsequently reversed when retrieval cues are provided. Using a combination of classic laboratory methods for manipulating interference and cuing, we repeatedly found high levels of blocked and recovered memories, even for materials that had sexually explicit and violent content. correspondence to Steven M.

This analysis provides a historical context for the debate about “true” and “false” childhood sexual abuse memories; discusses selected literature about conventional understandings of memory and their relevance to this debate; presents an integrative, phenomenological approach to memory in the recovery and rehabilitation of women child sexual abuse survivors; and uses the insights gained to draw conclusions about the authenticity of delayed childhood sexual abuse memories. Edward Casey’s phenomenological concepts of reminding, reminiscing, recognition, body memory, place memory, and commemoration are used to illuminate the complexity of traumatic memories and recovery and rehabilitation needs of the survivors of childhood sexual abuse.
Article excerpts: The notion of false accusation is often raised in cases where physical evidence is not available and a period of time has passed or when there has been a delay in recall of the events by a survivor of child sexual abuse. This is not to imply that false memories are not possible. This article outlines how rare they must be, however, based on historical factors and a phenomenological analysis of memory itself….During periods of increased visibility of sexual abuse of children, society tends to deny it because its existence fractures cultural values about family (Summit, 1988). From a historical perspective, the current controversy about the truth or falsehood of childhood sexual abuse memories is one in a series of societal repudiations of the existence and extent of childhood sexual abuse, especially incest (Herman, 1992; Olafson, Corwin, & Summit, 1993; van der Kolk et al., 1996).
In the majority of publicized discussions of false memory syndrome, it is the delayed memories of women that are being challenged, suggesting that at the heart of this controversy, there are also gender conflicts. Specifically, this controversy reinforces an image of women as not to be trusted or believed….Most scientists investigating traumatic memory doubt that memories of abuse could be planted. In fact, childhood sexual abuse survivors would rather not believe that they had been so betrayed and violated by a trusted adult. Recent research shows many false negatives and few false positives in terms of memories of abuse (Hardt & Rutter, 2004). Furthermore, caregivers who work closely with traumatized individuals battle the temptation to suppress survivors’ stories of abuse because such material tends to exhaust their own sense of efficacy, creativity, and hope (Herman, 1992).
Research shows that 64% of adult women childhood sexual abuse survivors had some degree of amnesia regarding the trauma; but in the majority of cases, corroboration was available to verify that abuse had occurred (Herman & Schatzow, 1987). Of 129 women with recorded histories of childhood sexual abuse, 38% did not recall the abuse that had been clearly verified and documented decades earlier. This lack of recall was especially likely among those abused at younger ages and among those whose perpetrators were known by them at the time of the abuse (L.Williams, 1994). In fact, a body of empirical evidence indicates that it is common for abused children to reach adulthood without conscious awareness of the trauma (Briere, 1992; Herman, 1992; Schetky, 1990; van der Kolk et al., 1996). http://abs.sagepub.com/cgi/reprint/48/10/1339?ijkey=ciZjJlFifgYIY&keytype=ref&siteid=spabs
Consider This, Skeptics of Recovered Memory Author: Ross E. Cheit DOI: 10.1207/s15327019eb0802_4 Ethics & Behavior, Volume 8, Issue 2 June 1998 , pages 141 – 160 Formats available: PDF (English) Abstract : Some self-proclaimed skeptics of recovered memory claim that traumatic childhood events simply cannot be forgotten at the time only to be remembered later in life. This claim has been made repeatedly by the Advisory Board members of a prominent advocacy group for parents accused of sexual abuse, the so-called False Memory Syndrome Foundation. The research project described in this article identifies and documents the growing number of cases that have been ignored or distorted by such skeptics. To date, this project has documented 35 cases in which recovered memories of traumatic childhood events were corroborated by clear and convincing evidence. This article concludes with some observations about the politics of the false memory movement, particularly the tendency to conceal or omit evidence of corroboration. Several instances of this vanishing facts syndrome are documented and analyzed. http://www.leaonline.com/doi/abs/10.1207/s15327019eb0802_4?journalCode=eb

theories on recovered memory:
http://dynamic.uoregon.edu/~jjf/defineBT.html The phrase “betrayal trauma” can be used to refer to a kind of trauma (independent of the reaction to the trauma). E.G. This definition is on the web: “Most mental health professionals have expanded the definition of trauma to include betrayal trauma. Betrayal trauma occurs when the people or institutions we depend on for survival violate us in some way. An example of betrayal trauma is childhood physical, emotional, or sexual abuse.” from http://www.loyola.edu/campuslife/healthservices/counselingcenter/trauma.html
The phrase “Betrayal Trauma theory” is generally used to refer to the prediction/theory about the cause of unawareness and amnesia as in: “Betrayal Trauma Theory: A theory that predicts that the degree to which a negative event represents a betrayal by a trusted needed other will influence the way in which that events is processed and remembered.” This definition is from: Sivers, H., Schooler, J. , Freyd, J. J. (2002) Recovered memories. In V.S. Ramachandran (Ed.) Encyclopedia of the Human Brain, Volume 4.(pp 169-184). San Diego, California and London: Academic Press. 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.” Freyd, J.(1994) Betrayal Trauma: Traumatic Amnesia as an Adaptive Response to Childhood Abuse. Ethics & Behavior 4 (4) p. 307-330 http://www.questia.com/read/95814385 The amnesia allows the child maintain attachment to a person that a child needs to depend on for survival and development.
Ground Lost: The False Memory/Recovered Memory Therapy Debate, by Alan Scheflin, Psychiatric Times 11/99, Vol. XVI Issue 11, “The appearance in the DSM-IV indicates that the concept of repressed memory is generally accepted in the relevant scientific community. This satisfies courts following the Frye v United States, 293 F.1013 (1923) or Daubert v Merrell Dow Pharmaceutical, 113 S. Ct. 2786 (1993) rules regarding the admissibility of scientific testimony into evidence in court.” And “Although the science is limited on this issue, the only three relevant studies conclude that repressed memories are no more and no less accurate than continuous memories (Dalenberg, 1996; Widom and Morris, 1997; Williams, 1995). Thus, courts and therapists should consider repressed memories no differently than they consider ordinary memories.” At http://www.psychiatrictimes.com/p991137.html

Recovered Memory and the Daubert Criteria : Recovered Memory as Professionally Tested, Peer Reviewed, and Accepted in the Relevant Scientific Community – Constance Dalenberg – Alliant International University California School of Professional Psychology – Trauma, Violence, & Abuse, Vol. 7, No. 4, 274-310 (2006) DOI: 10.1177/1524838006294572 Research during the past two decades has firmly established the reliability of the phenomenon of recovered memory. This review first highlights the strongest evidence for the phenomenon itself and discusses the survey, experimental, and biological evidence for the varying mechanisms that may underlie the phenomenon. Routes to traumatic amnesia from dissociative detachment (loss of emotional content leading to loss of factual content) and from dissociative compartmentalization (failure in integration) are discussed. Next, an argument is made that false memory is a largely orthogonal concept to recovered memory; the possibility of one phenomena is largely irrelevant to the potential for the other. Furthermore, some aspects of the false memory research offer supportive data for the recovered memory researcher. Finally, the issue of error rates in making the Daubert case is explored. It is concluded that the weight of the evidence should allow the recovered memory victim to come before the court. http://tva.sagepub.com/cgi/content/abstract/7/4/274
physiological evidence for memory suppression:
The Neurological Basis for the Theory of Recovered Memory http://ritualabuse.us/research/memory-fms/the-neurological-basis-for-the-theory-of-recovered-memory/
synopsis of part of van der Kolk, B. A. & Fisler, R. (1995) Dissociation and the fragmentary nature of traumatic memories: Overview and exploratory study. http://web.archive.org/web/20021211024350/http://www.trauma-pages.com/vanderk2.htm
van der Kolk and Fisler’s research shows that traumatic memories are retrieved, at least at first, in the form of mental imprints that are dissociated. These imprints are of the affective and sensory elements of the traumatic experience. Clients have reported the slow emergence of a personal narrative that can be considered explicit (conscious) memory. The level of emotional significance of a memory correlates directly with the memory’s veracity. Studies of subjective reports of memory show that memories of highly significant events are unusually accurate and stable over time. There are a variety of memory systems which usually operate outside of conscious awareness. These systems operate with some independence from the other memory systems. While people appear to easily assimilate expected and known experiences, aspects of traumatic experiences appear to get stuck in the mind, unaltered by time passing or experiences that may follow. The imprints of traumatic experiences appear to be qualitatively different from those of nontraumatic events. Explicit memories of personal facts or events are affected by lesions of the front lobe and hippocampus. These parts of the brain are also involved in PTSD neurobiology. Traumatic memories may be coded differently than ordinary event memories, possibly because of alterations in attentional focusing or the fact that extreme emotional arousal interferes with the memory functions of the hippocampus.
Traumas can interfere with several memory functions. van der Kolk divided these functional disturbances into four sets, traumatic amnesia, global memory impairment, dissociative processes and traumatic memories’ sensorimotor organization. Traumatic amnesia involves the loss of remembering traumatic experiences. The younger the subject and the longer the traumatic event is, the greater the chance of significant amnesia. Global memory impairment makes it difficult for these subjects to construct an accurate account of their present and past history. Dissociation refers to memories being stored as fragments and not as unitary wholes. Not being able to integrate traumatic memories seems to be the main element which leads to PTSD. In the sensorimotor organization of traumatic memories, sensations are fragmented into different sensory components.
Synopsis of part of van der Kolk, B. A. (1994). The body keeps the score: Memory and the evolving psychobiology of post traumatic stress. http://web.archive.org/web/20041204204758/http://www.trauma-pages.com/vanderk4.htm
Trauma victims do not respond to stress the way normals do. Pressure situations may cause a feeling of retraumatization. High states of arousal may promote the retrieval of trauma memories and associated phenomena such as sensory information or behaviors connected to prior trauma. Therefore, traumatic memories may be considered state dependent. Under stress, people secrete endogenous stress hormones that affect memory consolidation strength. Through studies on animal models, it is assumed that the large secretion of neurohormones during a traumatic event in part causes long-term potentiation (LTP) and the over-consolidation of traumatic memories. This LTP may cause an organism to remember a trauma whenever aroused. Neuroepinepehrine may be the major hormone causing LTP. Endorphins and oxytocin may actually cause inhibition of the consolidation of memories. Reliving the traumatic event may cause stress hormones to strength the memory trace causing a positive feedback loop.
The limbic system is believed to be critically involved in memory storage and retrieval as well as giving emotional significance to sensory inputs. Research in brain imaging studies suggests that trauma patients may have limbic system abnormalities. One part of the limbic system, the amygdala, may assign free-floating feelings to input which are then elaborated upon by the neocortex and imbued with personal meaning. It may also integrate internal representations of the external world in memory image form associating emotional experiences with these memories. The septo-hippocampal system is thought to record memory in temporal and spatial dimensions, and plays an important role in storing and categorizing incoming stimuli in memory. Hippocampal damage is connected to over responsiveness to external stimuli. When stress interferes with the hippocampus’ mediation of memory, it is possible that some of the memory is kept by a system that records emotional experience, but there is no symbolic placement of it in time or space. In animals, high stimulation of the amygdala interferes with hippocampal processing. Strong affect may disallow proper evaluating and categorizing of an experience.
Professor uncovers the nature of memories – Associate Professor Michael Anderson recently published a new study of what the brain does when a person forgets By Caron Alarab 1/14/03 “A University researcher is receiving international attention this week for a recent experiment exploring why people forget. With a team of Stanford researchers, Associate Professor of psychology Michael Anderson found people can use certain brain regions to block memories just as they do to control physical actions. “It’s no longer possible to say that human beings can’t actively forget,” said Anderson, one of the nation’s leading memory researchers. “Our research demystifies the idea of memory suppression.” The findings, which were published in the Jan. 9 issue of Science magazine, support Sigmund Freud’s controversial century-old theory about the existence of voluntary memory suppression. For the experiment, Anderson recruited Stanford researcher John Gabrieli and the two co-wrote the Science article “Neural Systems Underlying the Suppression of Unwanted Memories.” http://www.dailyemerald.com/
Research Reveals Brain Has Biological Mechanism To Block Unwanted Memories 1/9/04 “For the first time, researchers at Stanford University and the University of Oregon have shown that a biological mechanism exists in the human brain to block unwanted memories. The findings, to be published Jan. 9 in the journal Science, reinforce Sigmund Freud’s controversial century-old thesis about the existence of voluntary memory suppression. “The big news is that we’ve shown how the human brain blocks an unwanted memory, that there is such a mechanism and it has a biological basis,” said Stanford psychology Professor John Gabrieli, a co-author of the paper titled “Neural Systems Underlying the Suppression of Unwanted Memories.” “It gets you past the possibility that there’s nothing in the brain that would suppress a memory – that it was all a misunderstood fiction.” The experiment showed that people are capable of repeatedly blocking thoughts of experiences they don’t want to remember until they can no longer retrieve the memory, even if they want to, Gabrieli explained.” http://www.sciencedaily.com/releases/2004/01/040109072004.htm
The nature of traumatic memories: A 4-T FMRI functional connectivity analysis. Lanius RA, Williamson PC, Densmore M, Boksman K, Neufeld RW, Gati JS, Menon RS. Am J Psychiatry 2004 Jan; 161(1):36-44. RESULTS: Significant between-group differences in functional connectivity were found. Comparison of connectivity maps at coordinates x=2, y=20, z=36 (right anterior cingulate gyrus) for the two groups showed that the subjects without PTSD had greater correlation than the PTSD subjects in the left superior frontal gyrus (Brodmann’s area 9), left anterior cingulate gyrus (Brodmann’s area 32), left striatum (caudate), left parietal lobe (Brodmann’s areas 40 and 43), and left insula (Brodmann’s area 13). In contrast, the PTSD subjects showed greater correlation than the subjects without PTSD in the right posterior cingulate gyrus (Brodmann’s area 29), right caudate, right parietal lobe (Brodmann’s areas 7 and 40), and right occipital lobe (Brodmann’s area 19). CONCLUSIONS: The differences in brain connectivity between PTSD and comparison subjects may account for the nonverbal nature of traumatic memory recall in PTSD subjects, compared to a more verbal pattern of traumatic memory recall in comparison subjects.

Imagination inflation: A statistical artifact of regression toward the mean. Pezdek K, Eddy RM Mem Cognit 2001 Jul; 29(5):707-18; discussion 719-29 “In the imagination inflation procedure of Garry, Manning, Loftus, and Sherman (1996), subjects rated a list of events in terms of how likely each was to have occurred in their childhood. Two weeks later, some of the events were imagined; control events were not. The subjects then rated the likelihood of occurrence for each event a second time. Garry et al. (1996) reported that the act of imagining the target events led to increased ratings of likelihood. This finding has been interpreted as indicating that false events can be suggestively planted in memory by simply having people imagine them. The present study tests and confirms the hypothesis that the results that have been attributed to imagination inflation are simply a statistical artifact of regression toward the mean.” Author contact: Department of Psychology, Claremont Graduate University, California 91711-3955, USA. firstname.lastname@example.org http://www.ncbi.nlm.nih.gov/pubmed/11531226

False Memory Syndrome : A False Construct by Juliette Cutler Page “The concept of “recovered memory”, that is, memory of a traumatic event that had been forgotten for some period of time, has been variously explained by such mechanisms as repression, amnesia, and dissociation. However, there are over 100 years of reports and descriptions of recovered memory in the literature, including instances from times of war, torture, bereavement, natural disasters, and concentration camp imprisonment. (HOROWITZ) Many corroborated cases have been documented in instances of recovered memory of sexual abuse…”
“For example, women with known histories of abuse have been studied to determine if they had ever had periods in which the abuse had been forgotten. The abstract of Linda M. Williams’ 1995 study, Recovered memories of abuse in women with documented child sexual victimization histories. (Journal of Traumatic Stress, 8,649 — 673, 1995) states: The study provides evidence that some adults who claimed to have recovered memories of sexual abuse recall actual events that occurred in childhood. 129 women with documented histories of sexual victimization in childhood were interviewed and asked about abuse history. 17 years following the initial report of the abuse, 80 of the women recalled the victimization. One in 10 women (16 percent of those who recalled the abuse) reported that at some time in the past they had forgotten about the abuse. Those with a prior period of forgetting — the women with”recovered memories” — were younger at the time of abuse and were less likely to have received support from their mothers than the women who reported that they had always remembered their victimization. The women who had recovered memories and those who had always remembered had the same number of discrepancies when their account of the abuse were compared to the reports from the early 1970s. None of the women in this study who had forgotten the abuse were in therapy at the time they began to remember again, and women’s memories, when they returned, were consistent with the actual abuse.
Charles L. Whitfield, M.D. performed a review of 36 studies on over 6,000 children and adults who were abused as children. His results showed that between 16 and 78% of subjects in these studies experienced partial to total amnesia for their abuse for some substantial amount of time. Most of the subjects had been sexually abused as children. Eight of these studies involved only subjects with fully corroborated abuse histories, four had to a corroboration rate of 60 to 80 percent, and four had corroboration among half of the subjects. All groups were similar in occurrence of traumatic amnesia.
Elizabeth Loftus herself has published studies showing evidence of recovered memory. The 4 January 1996 issue of Accuracy About Abuse notes: Elizabeth Loftus, high profile FMSF advocate, published a paper with colleagues on Remembering and Repressing in1994. In a study of 105 women outpatients in a substance abuse clinic 54 % reported a history of childhood sexual abuse. 81% remembered all or part of the abuse. 19% reported they forgot the abuse for a period of time and later the memory returned. Women who remembered the abuse their whole lives reported a clearer memory, with a more detailed picture. Women who remembered the abuse their whole lives did not differ from others in terms of the violence of the abuse or whether the violence was incestuous. [Psychology of Women Quarterly, 18 (1994) 67-84.]
Loftus has also discussed “motivated forgetting”, and has presented the documented study of a college professor who became unable to remember a series of traumas, but after some time was able to recover those memories. Loftus remarked “after such an enormously stressful experience, many individuals wish to forget… And often their wish is granted.” (Loftus, 1980/1988, p. 73)” http://web.archive.org/web/20030608221633/http://www.feminista.com/v1n9/false-memory.html
How People Forget: The Truth About Delayed Memory Studies of Delayed Memory http://web.archive.org/web/20000609035705/http://ncasa.org/memory.html
That dissociation and amnesia are relatively common in child sexual abuse survivors is well-documented. There have been several recent studies that verify the repression of trauma and the fact of delayed memories: In a survey of 450 adults in treatment for child sexual abuse, 59% had periods in which they could not remember the abuse. (Briere and Conte, in press).
In a study of 53 women in therapy, Judith Herman and Emily Schatzow found that 74% were able to obtain corroborating evidence for the abuse, through witnesses, offenders’ diaries, pornographic pictures, offender confessions, and other sources. Nine percent found evidence that was “strongly suggestive, but not conclusive;” 11% did not try to confirm their memories; and only 6% found no supportive evidence. The conclusion of the researchers was that, “delayed recall of sexual abuse is as verifiable as any other form of disclosure.”
Interviews were conducted with 100 women who as children reported sexual abuse in 1973,1974 or 1975. The records of these girls were obtained from a city hospital emergency department which had interviewed the girls and the families and collected forensic evidence. In 1990 and 1991 the women, aged 18-31, were interviewed for two hours for what they were told was a study that examined the lives and health of women who obtained care at the hospital. In the course of the interview, the women were asked about their childhood experiences with sex. They were asked whether they or their families had ever reported childhood sexual abuse, or if anyone in their family ‘got in trouble’ for his or her sexual activities. Thirty-eight percent of the women either did not remember the abuse or chose not to report it to the interviewer. The interviewer states,”…qualitative analysis of these reports and non-reports suggests that the vast majority of the 38% were women who did not remember the abuse. They responded openly to other personal matters, and over one-half of the women who were amnestic reported other childhood victimizations.”
In the recent case of Father James Porter – a Catholic priest who admitted molesting more than100 boys and girls – many of his victims, now adults, remembered the abuse only after hearing about the case through the media. Even the first victim to come forward stated that there had been a period of amnesia for the abuse. In these cases, both the fact of the abuse and the reality of the delayed memories were confirmed.
Iatrogenic memory change. Examining the empirical evidence. Leavitt F Am J Forensic Psychol (19)2: 21-32, 2001. “Certainty of sexual abuse predated treatment in 33% of the cases. Therapeutic causation was unlikely in another 26% because personal certainty of abuse emerged on average 4.1 years after termination of treatment. The pattern was similar for groups treated with and without hypnosis. Remarkably few patients recovered first memories in therapy with the help of hypnosis. This study places the percentage at 4%. Thus, in the direct study of patients who recovered memory of childhood sexual abuse, hypnosis was not an important factor in the emergence of sexual abuse memories. …The results do not support widespread implanting of novel memories of sexual abuse by therapists.”
Suspected repressed childhood sexual abuse: Gender effects on diagnosis and treatment. Sullins CD Psychology of Women Quarterly 1998 Sep Vol 22(3) 403-418 “These results do not support reports that many therapists neglect clients’ current symptoms and instead focus on memories, use controversial techniques, make suggestive statements regarding abuse, or immediately assume that their clients have repressed memories.” J. Herman, author of “Trauma and Recovery” replies to Ethan Watters “Doors of Memory” (Jan./Feb. ’93) in Mother Jones http://www.motherjones.com/commentary/letters/1993/03/backtalk.html “by now exhaustively documented. Sexual abuse of children is common (best estimates: at least one girl in three, one boy in ten). It is not over reported but vastly under-reported (best estimates: under 10 percent of all cases come to the attention of child-protective agencies or police). False complaints do occur, but they are rare (best estimates: under 5 percent of all complaints). Most victims do not disclose their abuse until long after the fact, if ever. Though many suffer long-lasting psychological harm, the great majority never see a therapist.”
Is There a False Memory Epidemic? by Stephanie J. Dallam, RN, MSN, FNP ….Conclusions - There is no reliable evidence to substantiate claims that the false memory syndrome is a “growing problem”, a “crisis”, or that it constitutes an”epidemic”. Despite the False Memory Syndrome Foundation’s pledge to disseminate only accurate information on memory, their contact and membership statistics, as reported in their newsletters and in the media, reveal a disturbing lack of clarity and consistency. These same statistics, in turn, have provided credibility to claims that a false memory “epidemic” is sweeping the country. Although 25 studies have confirmed the reality of amnesia in sexually traumatized populations, no reliable research has provided evidence to substantiate the existence of the false memory syndrome as it is defined by the False Memory Syndrome Foundation. http://web.archive.org/web/19991128134659/http://idealist.com/tat/97-07-03-epidemic.shtml
“The hypothesis that false memories can easily be implanted in psychotherapy (Lindsay & Read, 1994; Loftus 1993; Loftus & Ketcham, 1994; Ofshe and Watters, 1993, 1994; Yapko, 1994a) seriously overstates the available data. Since no studies have been conducted on suggested effects in psychotherapy per se, the idea of iatrogenic suggestion of false memories remains an untested hypothesis.

U-Turn on Memory Lane by Mike Stanton - Columbia Journalism Review – July/August 1997
The FMSF builds much of its case against recovered memory by attacking a generally discredited Freudian concept of repression that proponents of recovered memory don’t buy, either. In so doing, the foundation ignores the fifty-year-old literature on traumatic, or psychogenic amnesia, which is an accepted diagnosis by the American Psychiatric Association. In his 1996 book “Searching for Memory,” the Harvard psychologist and brain researcher Daniel L. Schachter — who believes that both true and false memories exist — says there is no conclusive scientific evidence that false memories can be created….The foundation and its backers “remind me of a high school debate team,” says the Stanford psychiatrist David Spiegel, an authority on traumatic amnesia. “They go to the library, surgically extract the information convenient to them and throw out the rest.”….Many therapists, like their patients, hesitate to speak out.Recently, though, they have begun to make a more concerted effort to mobilize a response. One of the most outspoken critics of the false-memory movement is a Seattle therapist, David Calof, editor until last year of Treating Abuse Today, a newsletter for therapists. He has identified what he calls the movement’s political agenda — lobbying for more restrictive laws governing therapy and promoting the harassment of therapists through lawsuits and even picketing of their offices and homes. Calof himself has been the target of picketing so fierce that he has been in and out of Seattle courtrooms over the last two years, obtaining restraining orders. He was spending so much time and money fighting the FMSF supporters’ campaign against him, he says, that he was forced to stop publishing the newsletter last year. He recently donated the publication to a victims’ rights group in Pennsylvania, which has resurrected it as Trauma. The new publisher says that views part of its mission as reporting on FMSF, since the mainstream media don’t.
Among journalists, perhaps the most relentless critic of the foundation is Michele Landsberg, a Toronto Star columnist. In 1993, she says, an Ontario couple, claiming to have been falsely accused, contacted her and asked her to write about their case. Unconvinced, she declined, and eventually started writing instead about the foundation.She attacked its scientific claims and criticized the sensational media coverage. She described how a foundation scientific adviser, Harold Merskey, had testified that a woman accusing a doctor of sexual abuse in a civil case might in fact have been suffering from false memory syndrome. But the accused doctor himself had previously confessed to criminal charges of abusing her. Landsberg also challenged the credentials of other foundation advisers. She noted that one founding adviser, Ralph Underwager, was forced to resign from the foundation’s board after he and his wife, Hollida Wakefield, who remains an adviser, gave an interview to a Dutch pedophilia magazine in which he was quoted as describing pedophilia as”an acceptable expression of God’s will for love.” Landsberg also wrote that another adviser, James Randi, a magician known as “The Amazing Randi,” had been involved in a lawsuit in which his opponent introduced a tape of sexually explicit telephone conversations Randi had with teenage boys. (Randi has claimed at various times, she said, that the tape was a hoax and that the police asked him to make it.) “Why haven’t reporters investigated the False Memory Syndrome Foundation?” she asks. “It’s legitimate to examine their backgrounds –here are people who really do have powerful motivation to deny the truth.” http://web.archive.org/web/20071216011151/http://backissues.cjrarchives.org/year/97/4/memory.asp
Battle Tactics of the False Memory Syndrome Foundation - Noel Packard – New School for Social Research, N.Y. History Matters Conference April 23-24, 2004 Censorship is also a tactic that FMS Foundation adherents use to silence voices they don’t agree with. Katy Butler, published a critical review of Ofshe’s and Watter’s book, Making Monsters (1994) in the Los Angeles Times. Later the newspaper’s book review editor received a vague threat of a lawsuit from Ofshe’s representative (K. Butler personal communication with Lynn Crook January 28, 2000). Later Butler was asked to write a story for Newsweek examining the uncritical acceptance of Foundation claims and to provide documented cases of recovered memory and traumatic amnesia. Upon learning of this assignment Foundation Advisory Board members Richard Ofshe and Fredrick Crews, as well as Peter and Pamela Freyd, wrote strongly worded letters of complaint to Newsweek which effectively canceled Butler’s assignment (Stanton 1997). Although these censorship activities were reported in Mike Stanton’s article “U-Turn on Memory Lane” (1997) Nevertheless, Newsweek editors confirmed that the FMS Foundation letters helped kill Butler’s article. Butler said at a national conference of investigative reporters and editors in Rhode Island in 1996: “I’ve worked hard very hard to tell both sides of the story. What’s interesting to me about all of this that telling both sides has started to seem like a risky act.” (Stanton 1997: 49)….In 1994 the editor of the Journal of Psychohistory Lloyd DeMause wrote to many professional subscribers to inform them that he feared a lawsuit by the FMS Foundation for publishing a special issue of his journal on cult abuse. Dr. Jean Goodwin a psychiatrist at University of Texas Medical Branch responded with a letter that conveys the overall feeling among the mental health community in the early 1990s. Goodwin: From a Psychohistorical viewpoint it is fascinating to watch this organization systematically limit freedom of speech in this area. Their suits of publishers have driven many books out of print. Board members have prevented publication of many articles. As far as I know you are the first journal editor they have targeted. The slander suit stopped the audio-tapping of many presentations in this area. The licensing attacks and the malpractice suits threaten freedom of speech in the psychotherapy consulting room, which is where it is supposed to be most free. Silence still is the priority for the perpetrator (Goodwin 1994) Goodwin’s letter captures the effect that Foundations’ tactics had on the therapy community in the early 1990s. Today the overall effect of the Foundation’s court cases and tactics is more muted. One newly graduated MFT told me that as far as she knows the Foundation has had no impact on the practices of MFTs at all. A social worker who teaches a certification class on mandated reporting includes the Foundation topic in her lectures, saying that the Foundation “made us clean up our act.” I’ve also heard a seasoned MFT who teaches a class titled, “Counseling as a Career Option” lament that practicing psychotherapy is becoming a profession only for the rich (both as practitioners and clients). Perhaps this is due to recent constrictions and costs associated with lawsuits, training programs, licensing and insurance policies? It appears that the Foundations’ efforts to drive non-cognitive therapy beyond the grasp of un-wealthy clients are having some success. Kondora’s and Beckett’s studies indicate that the Foundation has been successful in many of its efforts to manage public perception of child abuse victims, therapists and the people accused of child abuse. Kondora and Beckett show that not only has public perception of victimized children become skeptical, but in fact, the press often goes beyond the Victorian custom of neutrality on all fronts of the issue, to out-right sympathy for accused molesters. What began in the 1960s and 1970s as a child welfare movement has arrived today as an accused sex-offender welfare movement (Goldsmith 2003); and right in time for an era when people are having more babies, less birth control and have easier ways to create home based child pornography than ever before. The Foundation has won many expensive malpractice lawsuits that have made news headlines. Such cases have probably put a chill into more than one therapy session, which is what they are intended to do. The Foundation’s efforts in and out of the court room have provided reasons for health insurance companies to reduce insurance payments for mental health care and have tied those payments generally to mental health diagnoses. Training programs for clinical therapists have become more like the clinical training programs of the cold-war years, more science oriented, more stringent, more biologically and drug oriented, and less theory and talked based. Many of the support groups, networks, newsletters, journals, and even significant names in the child welfare movement of the 1980′s and 1990′s have faded, vanished or been displaced by on-line and other services of the FMS Foundation.

Dr. Ofshe’s Testimony
In the Circuit Court of the Sixth Judicial Circuit of the State of Florida in and for Pinellas County Criminal Division State of Florida – CASE NO.: CRC99-18956CFANO Division: M – Nathan Brinkle – SPN: 01659274; Defendant. Order Denying Defendant’s Motion to Suppress #3, Motion to Suppress #4, and Amended Motion to Suppress #4 (Heard February 14, 2002, April 18,2002, and May 10, 2002)….Dr. Ofshe’s Testimony – After carefully listening to his testimony offered at the May 10, 2002 hearing, the court specifically declines to adopt any of the expert testimony offered by Dr. Ofshe. As explained below, the court found his testimony to lack credibility. First, the court specifically finds that Dr. Ofshe’s testimony on cross-examination, in a few critical areas, was wholly inconsistent with his testimony on direct-examination….
This observation leads the court to discuss another area of concern about Dr. Ofshe. It is clear to the court, after reading the transcript of the interview conducted at the Pinellas County Jail, that Dr. Ofshe did, in fact, ask the defendant numerous leading questions, and that he did indeed suggest to the defendant that he was bated, coerced, and improperly motivated during the interview (e.g., page 26, line 15:
Dr Ofshe: “You have to understand that they’re playing a game with you.”). During the interview, Dr. Ofshe repeatedly suggested and even told the defendant that he was manipulated and coerced, after which the defendant then stated: Okay. Now I’m catching on to what’s going on here…. For hours I was kind of lost before. I know she [defense counsel] told me what you was coming to really do, but, you know, until you get into it, until I get into it, you know, it really then- it’s really not dawned on me. [Transcript of Interview at Pinellas County Jail: pages 20-21 ].
That the defendant was ill prepared for the interview does not, in the court’s opinion justify a blatant attempt to “coach” the defendant or convince him that he was psychologically coerced. Although this arguably goes to the defendant’s theory of the case and the preparation thereof, it is a factor that the court can consider as the fact-finder to determine the expert witness’ credibility. For all of the reasons listed above, the court rejects the testimony of Dr. Ofshe, finding him to lack credibility. In deciding to reject his testimony for purposes of these pretrial motions, the court makes no comment on the admissibility of Dr. Ofshe’s testimony at trial or whether he is qualified as an expert to testify at trial. Boyer v. State, 2002 WL 925015, 27 Fla. L. Weekly D 1113 (Fla. 5-th DCA 2002) (holding that the trial court erred in excluding Dr. Ofshe’s testimony at trial after finding him qualified to testify as an expert where Dr. Ofshe’s testimony went to the defendant’s main defense). http://www.reid.com/educational_info/criticnbrinkley.html
