Directed forgetting of trauma cues in adults reporting repressed or recovered memories of childhood sexual abuse

An item-cuing directed forgetting task was used to investigate whether women reporting repressed (n = 13) or recovered (n = 13) memories of childhood sexual abuse (CSA) exhibit an avoidant encoding style (and resultant impaired memory) for trauma cues relative to women reporting no CSA experience (n = 15). All participants viewed intermixed trauma (e.g., molested), positive (e.g., confident), and categorized neutral (e.g., mailbox) words on a computer screen and were instructed either to remember or to forget each word. The results provided no support for the hypothesis that people reporting either repressed or recovered memories of CSA are especially adept at forgetting words related to trauma. These groups recalled words they were instructed to remember more often than words they were instructed to forget regardless of whether they were trauma related.     

Forgetting of trauma cues in adults reporting continuous or recovered memories of childhood sexual abuse

According to betrayal trauma theory, adult survivors of childhood sexual abuse (CSA) who were molested by their caretakers (e.g., a father) are especially likely to dissociate ("repress") their memories of abuse. Testing college students, some reporting CSA, DePrince and Freyd (2004) found that those scoring high on a dissociation questionnaire exhibited memory deficits for trauma words when they viewed these words under divided-attention conditions. Replicating DePrince and Freyd's procedure, we tested for memory deficits for trauma words relative to neutral words in adults reporting either continuous or recovered memories of CSA versus adults denying a history of CSA. A memory deficit for trauma words under divided attention was expected in the recovered-memory group. Results were inconsistent with this prediction, as all three groups exhibited better recall of trauma words than neutral words, irrespective of encoding conditions.     

Reality monitoring in adults reporting repressed, recovered, or continuous memories of childhood sexual abuse

People who report either repressed or recovered memories of childhood sexual abuse (CSA) may have deficits in reality monitoring--the process whereby one discriminates memories of percepts from memories of images. Using signal detection methods, the authors found that adults reporting either repressed or recovered memories of CSA were less able to discriminate between words they had seen from words they had imagined seeing than were adults reporting either never having forgotten their CSA or adults reporting no history of CSA. Relative deficits in the ability to discriminate percepts from images (i.e., low d') were apparent on only some tests. The groups did not differ in their criterion--response bias--for affirming having seen versus imagined stimuli.     

Autobiographical memory specificity in adults reporting repressed,recovered, or continuous memories of childhood sexual abuse

Some psychotherapists believe that adult survivors of childhood sexual abuse (CSA) are characterised by memory deficits for their childhood. Using the Autobiographical Memory Test (AMT), we asked nonabused control participants and participants who reported either continuous, recovered, or repressed memories of CSA to retrieve a specific personal memory in response to either positive or negative cue words from either childhood or adolescence/adulthood. The results indicated that participants who believed they harboured repressed memories of abuse tended to exhibit the greatest difficulty retrieving specific memories from their childhood. Neither posttraumatic stress disorder (PTSD) nor major depression was related to diminished memory specificity.     

Retrieval inhibition of trauma-related words in women reporting repressed or recovered memories of childhood sexual abuse

Several authors have argued that survivors of childhood sexual abuse (CSA) who report to have repressed their traumatic memories are more skilled in forgetting emotional stimuli than survivors who have always remembered the abuse. The current experiment employed a list-wise directed forgetting task to investigate whether women reporting repressed (n = 16) or recovered (n = 23) memories of CSA are better at forgetting disturbing material, relative to women reporting having always remembered their abuse (n = 55) or reporting no history of abuse (n = 20). We found no support for the hypothesis that women reporting repressed or recovered memories of CSA are especially versed in inhibiting retrieval of trauma-related words. Additional analyses revealed that participants characterized by a repressive coping style did not display a superior retrieval inhibition mechanism for negative material.     

Inhibiting retrieval of trauma cues in adults reporting histories of childhood sexual abuse

Are people who report having forgotten their childhood sexual abuse (CSA) characterised by superior ability to inhibit retrieval of disturbing material? To test this hypothesis, we asked adults reporting either repressed, recovered, or continuous memories of CSA or no history of CSA to participate in a directed forgetting experiment (list method). They rated the emotionality of two consecutive lists of trauma‐related and positive words. After the first list, the experimenter instructed participants to forget these words, and to continue rating the remaining words. A surprise recall task revealed robust directed forgetting and valence effects: All groups recalled more words from the second list than from the first list, and recalled more trauma words than positive ones. Participants reporting either repressed or recovered memories of CSA did not exhibit superior forgetting of trauma versus positive words relative to the other two groups. Finally, a subsidiary analysis revealed that participants exhibiting a “repressor” coping style (low self‐reported anxiety plus high defensiveness) did not exhibit superior directed forgetting of trauma words.     

Forgetting of prior remembering in persons reporting recovered memories of childhood sexual abuse

Case studies of individuals reporting recovered memories of childhood sexual abuse suggest that some overestimate their prior forgetting of the abuse. People reporting recovered or continuous memories of childhood sexual abuse and control subjects reporting no history of abuse participated in two experiments examining this "forgot it all along" phenomenon. Participants in Experiment 1 were more likely to forget that they had previously recalled a studied item if they were cued to think of it differently on two recall tests than if they were cued to think of it in the same way on the two tests. This effect was stronger for recovered-memory participants than for continuous-memory and control participants. In Experiment 2, participants recalled autobiographical events three times over a period of 4 months. Much as in Experiment 1, they underestimated prior remembering when the events had been recalled in a different emotional frame (positive vs. negative) on the previous occasion. This underestimation was more pronounced for recovered-memory participants than for continuous-memory and control participants.     

The reality of recovered memories: corroborating continuous and discontinuous memories of childhood sexual abuse

Although controversy surrounds the relative authenticity of discontinuous versus continuous memories of childhood sexual abuse (CSA), little is known about whether such memories differ in their likelihood of corroborative evidence. Individuals reporting CSA memories were interviewed, and two independent raters attempted to find corroborative information for the allegations. Continuous CSA memories and discontinuous memories that were unexpectedly recalled outside therapy were more likely to be corroborated than anticipated discontinuous memories recovered in therapy. Evidence that suggestion during therapy possibly mediates these differences comes from the additional finding that individuals who recalled the memories outside therapy were markedly more surprised at the existence of their memories than were individuals who initially recalled the memories in therapy. These results indicate that discontinuous CSA memories spontaneously retrieved outside of therapy may be accurate, while implicating expectations arising from suggestions during therapy in producing false CSA memories.     

False recognition in women reporting recovered memories of sexual abuse

False recognition—the mistaken belief that one has previously encountered a novel item—was examined in four groups of subjects: women reporting recovered memories of childhood sexual abuse, women who believe that they were sexually abused as children but who cannot recall this abuse (the "repressed" group), women who were sexually abused as children and always remembered the abuse, and women with no history of childhood sexual abuse. Subjects were administered a Deese/Roediger-McDermott paradigm. The results suggest that the recovered-memory group was more prone to false recognition than the other groups. In addition, women reporting recovered and repressed memories showed greater reduction in false recognition across study trials than did other subjects, perhaps reflecting strategic changes in performance.     

Fantasy proneness, but not self-reported trauma is related to DRM performance of women reporting recovered memories of childhood sexual abuse

Extending a strategy previously used by , we administered a neutral and a trauma-related version of the Deese-Roediger-McDermott paradigm to a sample of women reporting recovered (n=23) or repressed memories (n=16) of childhood sexual abuse (CSA), women reporting having always remembered their abuse (n=55), and women reporting no history of abuse (n=20). We found that individuals reporting recovered memories of CSA are more prone than other participants to falsely recalling and recognizing neutral words that were never presented. Moreover, our study is the first to show that this finding even held when trauma-related material was involved. Correlational analyses revealed that fantasy proneness, but not self-reported traumatic experiences and dissociative symptoms were related to false recall and false recognition.     

Autobiographical memory specificity after manipulating retrieval cues in adults reporting childhood sexual abuse

Traumatized samples have relative difficulty in generating specific autobiographical memories on a cue word task, compared to nonexposed controls. Simultaneously, trauma is associated with highly specific intrusive trauma memories in day-to-day life. Possibly, day-to-day intrusions and memories generated to cue words rely on different retrieval processes, with the former dependent on close associations between retrieval cues and specific memory representations (direct retrieval), and the latter on iterative retrieval cycles through a hierarchical memory system (generative retrieval). This study investigated this distinction using two versions of the cue word task, designed to promote generative and direct retrieval, respectively, in participants with or without a history of child sexual abuse (CSA). The data demonstrated that CSA participants were less specific than nonabused controls to generative retrieval cues, but this difference disappeared with direct retrieval cues. This interaction was stronger in CSA participants with relatively greater posttraumatic stress and remained significant when participants with past or current major depressive disorder were excluded and also when only those participants with corroborated CSA were included.     

Linking thought suppression and recovered memories of childhood sexual abuse

There are two types of recovered memories: those that gradually return in recovered memory therapy and those that are spontaneously recovered outside the context of therapy. In the current study, we employed a thought suppression paradigm, with autobiographical experiences as target thoughts, to test whether individuals reporting spontaneously recovered memories of childhood sexual abuse (CSA) are more adept at suppressing positive and anxious autobiographical thoughts, relative to individuals reporting CSA memories recovered in therapy, relative to individuals with continuous abuse memories, and relative to controls reporting no history of abuse. Results showed that people reporting spontaneously recovered memories are superior in suppressing anxious autobiographical thoughts, both in the short term and long term (7 days). Our findings may partly explain why people with spontaneous CSA memories have the subjective impression that they have "repressed" their CSA memories for many years.     

Reports of recovered memories of childhood abuse in therapy in France

ABSTRACT

Recovered memories of abuse in therapy are especially controversial if the clients were not aware they were abused before therapy. In the past, such memory recovery has led to legal action, as well as a debate about whether such memories might be repressed, forgotten, or false memories. More than two decades after the height of the controversy, it is unclear to what degree such memories are still recovered today, and to what extent it occurs in France. In our French survey of 1312 participants (M_age?=?33; 53% female), 551 reported having done therapy at some point. Of that 551, 33 (6%) indicated they had recovered memories of abuse in therapy that they did not know about before therapy. Sexual abuse was the most commonly reported type that was recovered in therapy (79%). As in past research, discussing the possibility of repressed memories with therapists was associated with reports of recovered memories of abuse. Surprisingly, memory recovery occurred just as much in behavioural and cognitive therapies as it did in therapies focused on trauma. We found recovered memories in a proportion of clients who began therapy recently. Recovered memories in therapy appears to be an ongoing concern in France.     

The effect of multiple childhood sexual assaults on mock-jurors' perceptions of repressed memories

The effect of multiple childhood sexual assaults on the believability of a repressed memory of the assault was assessed using mock jurors. Participants read a fictional civil trial summary about a child sexual assault case presented in one of three reporting conditions: (a) immediate condition-the alleged victim testified immediately after the assault(s); (b) repressed condition-the alleged victim reported the assault(s) 20 years later, after remembering it/them for the first time; or (c) no-repressed condition-the alleged victim reported the assault(s) 20 years later, but the memory of the assault(s) had been present for those years. The number of assaults was either one or 30. The results showed that for all reporting conditions 30 alleged assaults led to relatively more decisions for the plaintiff than the defendant, and greater believability of the plaintiff. The increases in decisions rendered and believability were also generally true for the immediate condition compared to when there was a delay in reporting. The results are discussed in terms of mock jurors' perceptions of child sexual assault, both those reported immediately and those reported after many years.     

Cognitive processing therapy for chronic PTSD from childhood sexual abuse: A case study

This paper describes a case of chronic Post-traumatic Stress Disorder (PTSD), as described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV, 4th edn; American Psychiatric Association, 1994). The client has a long history of childhood sexual abuse (CSA), as well as repeated sexual victimization as an adult and addiction issues. She presented with significant avoidance symptoms, including a highly restricted range of affect and distinct feelings of detachment from others. These symptoms had been greatly reduced by the end of the 17-week therapy including both individual and group modalities. The paper elaborates on theoretical issues, the Cognitive Processing Therapy model (Resick & Schnicke, 1993) as it was adapted for use with survivors of childhood sexual abuse, the various phases of the therapeutic process, and specific examples of therapeutic change with this particularly complicated case.     

Surviving roots of trauma: prevalence of silent signs of sex abuse in patients who recover memories of childhood sex abuse as adults

Recent research suggests that victimization imagery is chronically accessible in sex-abused populations, which is helpful in distinguishing them from nonabused populations. Eight categories of victimization imagery were selectively activated by Rorschach stimuli. These 8 sex-abuse signs were replicated in a new sample of 36 patients with continuous memory of sex abuse. Classification accuracy was 83%. By contrast, these signs were present in only 4% (5 of 115) of the protocols of nonabused patients. Taken together, the 2 studies confirm reasonably high sensitivity of the 8 signs for sex-abused populations and high specificity for nonabused populations. The 8 signs were also differentially salient for patients who recovered memory of childhood sexual trauma as adults. The Rorschach protocols of 59 of 114 patients with delayed recall of sexual abuse possessed signs of sex abuse. There was no linkage between therapy and recovered-memory cases with and without sex-abuse signs. Emergence of trauma memories was not uniquely traceable to treatment. Memories arose outside of the context of therapy in over 56% of the cases. Implications for the false-memory debate are discussed.     

False memories in women with self-reported childhood sexual abuse: an empirical study

Although controversy exists about the validity of memories of childhood abuse, little is known about memory function in individuals reporting childhood abuse. This study assessed memories for previously presented words, including the capacity for false memory of critical lures not actually present in the word list, in 63 subjects, including abused women with posttraumatic stress disorder (PTSD), abused women without PTSD, and men and women without abuse or PTSD. Abused women with PTSD had a higher frequency of false recognition memory of critical lures (95%) than abused women without PTSD (78%), nonabused women without PTSD (79%), or nonabused men without PTSD (86%). PTSD women also showed poorer memory for studied words and increased insertions of non-studied words other than critical lures. These findings are consistent with a broad range of memory alterations in abused women with PTSD.     

Iatrogenic creation of false childhood sexual abuse memories: Controversy,dynamics, fantasy,and reality

This paper examines the phenomenon of False Memory Syndrome (FMS). In the last decade there has been an increase in the number of adult individuals who report childhood sexual abuse only to recant their allegations. Recanters and the falsely accused are specifying that therapeutic interventions by trusted and, at times, well intentioned therapists facilitated their false memories. The theory of repression, reliability of memory, recovery techniques, and characteristics of therapist and clients are explored. This paper also discusses a number of cases that have been filed, and some guidelines for therapists who work or plan to work in the recovery of repressed memories.     

People believe it is plausible to have forgotten memories of childhood sexual abuse

Pezdek, Blandon-Gitlin, and Gabbay (2006) found that perceptions of the plausibility of events increase the likelihood that imagination may induce false memories of those events. Using a survey conducted by Gallup, we asked a large sample of the general population how plausible it would be for a person with longstanding emotional problems and a need for psychotherapy to be a victim of childhood sexual abuse, even though the person could not remember the abuse. Only 18% indicated that it was implausible or very implausible, whereas 67% indicated that such an occurrence was either plausible or very plausible. Combined with Pezdek et al.’s findings, and counter to their conclusions, our findings imply that there is a substantial danger of inducing false memories of childhood sexual abuse through imagination in psychotherapy.
