Recovered memories of alleged sexual abuse: Lawsuits against parents

Recently there has been increased civil litigation by adults suing parents and others for sexual abuse following the recovering of memories of the abuse through therapy. The memories are recovered with the help of therapists who use concepts such as repression and dissociation to account for the lack of memories and who then use techniques such as hypnosis and survivors' groups. However, the claims of repressed memories of childhood sexual abuse recovered in the course of therapy are unlikely to be supported by empirical data.     

Seeking the Core: The Issues and Evidence Surrounding Recovered Accounts of Sexual Trauma

This review identifies some of the many layers that surround and potentially obscure the emotionally charged topic of recovered accounts of childhood abuse. Consideration of the, admittedly often indirect, evidence provides suggestive support for many of the components of both recovered and fabricated memories of abuse. With respect to recovered memories the available evidence suggests that: (1) although the prior accessibility of a memory may be difficult to determine, recovered memory reports can sometimes be corroborated with respect to their correspondence to actual abuse; (2) although individuals often retain memory for trauma, there is evidence for fluctuations in the accessibility of traumatic experiences, particularly for situations that are extremely difficult to talk about; (3) there are compelling mechanisms available to account for both the decreases and the subsequent increases in accessibility of traumatic memories that could lead to recovered memory reports. With respect to fabricated memories the available evidence suggests that: (1) people are highly capable of fabricating vivid recollections that can be confused with reality; (2) once fabricated, there seems to be no limit to the preposterous false memories that some individuals are capable of accepting particularly when in the presence of a persuasive individual in a position of authority. Although future research is needed to provide more direct evidence for the above claims, at present readers are urged to consider the strong likelihood that both recovered and fabricated memories correspond to real phenomena.     

What people believe about memory

Two representative samples of adult Norwegians (n=2000) were asked a set of general and specific questions regarding their beliefs and opinions about human memory. The results indicate that on many questions, such as time of the earliest memories, inhibiting effects of collaboration, and memory for dramatic versus ordinary events, the views of the general public concurred with current research findings, and people in general had realistic views about their own memory performance. On other questions, such as the reliability of olfactory as compared with visual and auditory memory, the memory of small children in comparison with that of adults, the likelihood of repression of adult traumatic memories, and on more general questions such as the possibility of training memory and the capacity limitations of long-term memory, a large proportion of the participants expressed views that are less supported by scientific evidence. Implications of these findings are briefly discussed.

Mood,dissociation and false memories using the Deese‐Roediger‐McDermott procedure

Who is likely to have a false memory? Does being in a certain transient state, such as a negative mood, mean that a person is more like to have a false memory? These important questions are examined using the Deese‐Roediger‐McDermott (DRM) procedure. The amount of false memories was compared with people's score on a dissociation measure and by mood. Unlike past research, which has used different procedures to explore false memories, we found that dissociation was not associated with false memories. We argue that this is because the DRM procedure requires two processes for a false memory (the generation of the critical lure and mistaking its source), while most false memory procedures only require one process (source monitoring error) because the errant information is suggested to the participant. This pattern of results suggests that only errors with the source monitoring process are associated with dissociation. We found that mood was related to false memories, but it was dependent on the specific task demands. If participants were told to recall as many words as they could, then people in a negative mood had more false memories. However, if they were told to recall as many words as they felt like recalling, then there were more false memories for people in a positive mood. This can be explained by the mood‐as‐input hypothesis. Results are discussed in relation to both theories and applications of memory.     

Recovered Memories of Child Abuse:

In this paper we exemplify the ongoing and inconclusive nature of empirical research examining the validity of adults' recovered memories of childhood abuse. In view of increasing evidence that the processes underlying traumatic memories differ in fundamental ways from those underlying memories for nontraumatic events, experimental studies of everyday memory processes are likely to have little relevance for our understanding of the memory processes underlying traumatic child abuse. Further, given ethical concerns, it is unlikely that research will ever establish a definitive 'scientific' conclusion regarding the accuracy of recovered memories. Nevertheless, both laypersons and professionals are taking a stand on the recovered memory issue. In this regard, we discuss social psychological research that suggests that people's beliefs about recovered memories and other aspects of child abuse are tied to their personal needs and sociopolitical interests rather than to science or social values. These personal needs and interests include people's inability to acknowledge the injustice of child abuse and their opposition to women's equality, both of which vary as a function of people's authoritarian inclinations. The implications of these findings for social action, as opposed to social research, are discussed.     

A New Solution to the Recovered Memory Debate

ABSTRACT— The controversy regarding recovered memories of childhood sexual abuse (CSA) has been characterized by two perspectives. According to one perspective, some people repress their memories of abuse because these experiences have been so emotionally traumatic, and they become capable of recalling the CSA only when it is psychologically safe to do so many years later. According to the other perspective, many reports of recovered memories of sexual abuse are false memories, often inadvertently fostered by therapists. In this article, we provide evidence for a third interpretation that applies to a subset of people reporting recollections of CSA; it does not require the concepts of repression, trauma, or false memory. These people did not experience their CSA as traumatic; they either failed to think about their abuse for years or forgot their previous recollections, and they recalled their CSA spontaneously after encountering reminders outside of psychotherapy. Their recovered memories are corroborated at the same rate as those of people who never forgot their abuse. Hence, recalling CSA after many years is not the same thing as having recalled a previously repressed memory of trauma.     

Autobiographical memory for trauma: update on four controversies

Empirical research since the year 2000 on trauma and autobiographical memory in adults is reviewed and related to four enduring controversies in the field: Whether traumatic memories are inherently different from other types of autobiographical memory; whether memory for trauma is better or worse than memory for non-traumatic events; whether traumas can be forgotten and then recalled later in life; and whether special mechanisms such as repression or dissociation are required to account for any such forgetting. The review concludes that trauma and non-trauma memories differ substantially, but only in clinical and not in healthy populations. Whereas involuntary memory is enhanced in clinical populations, voluntary memory is likely to be fragmented, disorganised, and incomplete. Progress in experimental and neuroimaging research will depend on analysing how task performance is affected by the interaction of voluntary and involuntary memory and by individual tendencies to respond to trauma with increased arousal versus dissociation.     

Cognitive Mechanisms Underlying Recovered-Memory Experiences of Childhood Sexual Abuse

ABSTRACT— People sometimes report recovering long-forgotten memories of childhood sexual abuse. The memory mechanisms that lead to such reports are not well understood, and the authenticity of recovered memories has often been challenged. We identified two subgroups of people reporting recovered memories of childhood sexual abuse. These subgroups differed dramatically in their cognitive profiles: People who recovered memories of abuse through suggestive therapy exhibited a heightened susceptibility to the construction of false memories, but showed no tendency to underestimate their prior remembering. Conversely, people who recovered memories of abuse spontaneously showed a heightened proneness to forget prior incidences of remembering, but exhibited no increased susceptibility to false memories. This double dissociation points to mechanisms that underlie recovered-memory experiences and indicates that recovered memories may at times be fictitious and may at other times be authentic.     

Gender, personality, and involuntary autobiographical memory

We utilised the recently developed continuous word association task (CWAT) to investigate whether attributes of involuntary autobiographical memory, including gender and cue valence effects, were similar to those found for voluntary autobiographical memory, as well as investigating the role of individual differences in memory production. A total of 80 undergraduate volunteers reported involuntary memories that came to mind during the word association task and completed measures of trait dissociation and psychosis-proneness. Involuntary memories showed similar cue valence effects to those typically found with voluntary memories but the usual gender effect was only apparent once participants learned the task involved autobiographical memory. The total number of involuntary autobiographical memories produced in response to negative cue words was related to greater trait dissociation and psychosis-proneness. The implications for differences between voluntary and involuntary autobiographical memory are discussed.     

Evaluation of the evidence for the trauma and fantasy models of dissociation

The relationship between a reported history of trauma and dissociative symptoms has been explained in 2 conflicting ways. Pathological dissociation has been conceptualized as a response to antecedent traumatic stress and/or severe psychological adversity. Others have proposed that dissociation makes individuals prone to fantasy, thereby engendering confabulated memories of trauma. We examine data related to a series of 8 contrasting predictions based on the trauma model and the fantasy model of dissociation. In keeping with the trauma model, the relationship between trauma and dissociation was consistent and moderate in strength, and remained significant when objective measures of trauma were used. Dissociation was temporally related to trauma and trauma treatment, and was predictive of trauma history when fantasy proneness was controlled. Dissociation was not reliably associated with suggestibility, nor was there evidence for the fantasy model prediction of greater inaccuracy of recovered memory. Instead, dissociation was positively related to a history of trauma memory recovery and negatively related to the more general measures of narrative cohesion. Research also supports the trauma theory of dissociation as a regulatory response to fear or other extreme emotion with measurable biological correlates. We conclude, on the basis of evidence related to these 8 predictions, that there is strong empirical support for the hypothesis that trauma causes dissociation, and that dissociation remains related to trauma history when fantasy proneness is controlled. We find little support for the hypothesis that the dissociation-trauma relationship is due to fantasy proneness or confabulated memories of trauma.     

A Process Analysis of the Effects of Humorous Advertising Executions on Brand Claims Memory

We report 2 studies that examined how the strength of humorous advertising executions and their relevance to the brand claims in the advertisement influence consumer memory for the claims. We infer the underlying memory processes by testing claims memory using recall, recognition, and indirect tests following incidental exposure to advertisements manipulating humor strength and claims relevance. Memory for the humor component was checked as corroborating evidence. We also validated these inferences by contrasting these effects on claims and humor memory with those under instructed elaboration. Study 1 shows that for humor of low claims relevance, brand claims memory is an inverted U‐shaped function of humor strength. Compared to both nonhumor and high‐strength humor, moderate humor facilitates both encoding and retrieval of the claims. The patterns of humor memory and instructed elaboration effects suggest that low‐relevance humor is not spontaneously linked to the claims even when processing resources are available. Study 2 shows that when strong humor is made more relevant, brand claims memory improves even during incidental exposure. Corresponding humor memory and instructed elaboration effects imply that relevance encourages the formation of humor‐claims links that facilitate encoding and retrieval of the claims. The results show that although strong humor inhibits the processing received by the brand claims, enhancing its claims relevance can compensate for such inhibition.     

Three peas in the pod of consumer imagination: Purchase task,involvement, and ad information

The research investigates the mediating role of the consumer imagination in persuasion, depending upon level of involvement, nature of the purchase task, and ad information. The consumer imagination is conceptualized as combining triggered information from memory with incoming ad information to simulate a yet‐to‐be‐experienced event. The research reveals how obstacles to information flowing from memory or information from incoming peripheral ad claims suppress the enhancing effects of the consumer imagination. Across three studies, the findings indicate that few incoming peripheral ad claims are an obstacle to the consumer imagination in a utilitarian context, regardless of involvement, because preferred peripheral claims are reduced. Low involvement is an obstacle to the consumer imagination in a hedonic context, because it reduces the need to rely on triggered memories. However, this effect is reversed with more peripheral ad claims, because increased claims help to build up the imagination when reliance on triggered memories is reduced. Theoretical discussion is provided about how the imagination expands the elaboration of ad details by retrieving relevant experiences from memory to create mental rehearsals.

False claims about false memory research

Pezdek and Lam [Pezdek, K. & Lam, S. (2007). What research paradigms have cognitive psychologists used to study "False memory," and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been (1) misusing the term "false memory," (2) relying on the wrong methodologies to study false memories, and (3) misapplying false memory research to real world situations. We review each of these claims and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors.     

Recall and recognition of threatening,pleasant, and neutral words in repressors

Low accessibility of threatening information is a crucial element in the theory of repression. Despite many attempts, no empirical evidence has been found for such an inverse memory bias in normal subjects. An alternative approach is to study repressive processes as an individual difference. Adopting such a trait approach, several studies have shown impaired memory for threatening memories of real‐life episodes in so‐called repressors. Several other studies have yielded evidence of avoidant processing of mildly threatening information in the early stages of information processing in repressors. Thus far, little evidence for a similar avoidant bias in memory has been offered for repressors. To demonstrate the presence of memory deficits for mildly threatening information, we tested recall and cued recognition after a 30 min delay, for (i) threatening, (ii) pleasant, and (iii) neutral words in repressors and non‐repressors. No proof was found for poorer recall and recognition of threatening words in repressors, or for lower numbers of threatening semantic intrusions in these individuals, while the power of the study was adequate. While repression‐related avoidant processing may be present for even mildly threatening stimuli at earlier stages of information processing, the results of the present study indicate that repressed memory may only show up for relatively intense emotional events.

A bibliometric analysis of the recovered memory controversy in the 21st century

In the 1990s, repressed and recovered memories were at the heart of intense debates within the clinical field as well as in academia. Recent data suggest that this controversy has not yet been resolved in the clinical field. However, it is unclear to what extent repressed and recovered memories are studied in peer‐reviewed outcomes in the 21st century. The current article examined the volume of publications and citations regarding repressed and/or recovered memories during the years 2001–2018. Analysis of the 145 articles retrieved shows that these issues are still being investigated within the academic sphere. Proponents and opponents of repressed memories regularly published articles, and these were cited as often as articles published during the 1990s. These issues were also multidisciplinary (i.e., social/clinical/experimental psychology, psychiatry, and law) and often dealt with dissociation, child abuse, and/or false memory. The results are encouraging for furthering the research field and for the understanding of traumatic memory mechanisms.     

Trait dissociation and the subjective affective, motivational, and phenomenological experience of self-defining memories

The present research reports 2 studies that examine the relation between nonpathological trait dissociation and the subjective affect, motivation, and phenomenology of self-defining memories. In Study 1 (N=293), participants retrieved and rated the emotional and motivational experience of a general and a positive and negative achievement-related memory. Study 2 (N=449) extended these ratings to relationship-related memories and the phenomenological experience of the memory. Dissociation was associated with incongruent affect in valenced memories (e.g., positive affect in a negative memory) and memories that were visually incoherent and saturated with power motivation, hubristic pride, and shame, regardless of valence or domain. The present findings demonstrate that autobiographical memories, which integrate emotional, motivational, and phenomenological components, reflect the emotional and motivational processes inherent to dissociation.     

The effect of emotional stress on involuntary and voluntary conscious memories

Clinical theories of post-traumatic stress disorder often claim that intrusive (involuntary) memories favour emotionally stressful material and that these memories come with more sensory imagery and emotional reliving compared to voluntary memories. However, these assumptions have not been verified experimentally. Here we obtained recordings of emotional reactions to aversive pictures at the time of encoding, as well as records of involuntary and voluntary memories of these pictures in a subsequent diary study. A comparison of individual ratings, obtained during encoding, of pictures recalled involuntarily and voluntarily showed that emotional stress at encoding increased overall accessibility, independent of whether recall was voluntary or involuntary. However at the time of recall, voluntary memories scored higher on narrative content and on measures of imagery. The findings are compatible with research on emotion and memory in general, but challenge clinical claims of differential involuntary versus voluntary access to emotionally stressful events.     

A jigsaw puzzle theory of memory

The principal novel feature of this paper is the notion that a coherent memory can be synthesised from a set of partially coherent memory fragments by maximising a particular function, Harmony (Smolensky, 1986). The appeal of Harmony is that it fulfils two functions: it is at the heart of the synthesis algorithm and it provides a natural measure for "feeling-of-knowing". The model is applied to feeling-of-knowing data, flashbulb memories, flashbacks, repression, dissociation, memory stability across repeated recalls, and the effects of cue size on retrieval.     

Reliving,emotions, and fragmentation in the autobiographical memories of veterans diagnosed with PTSD

Fifty veterans diagnosed with posttraumatic stress disorder (PTSD) each recalled four autobiographical memories: one from the 2 years before service, one non‐combat memory from the time in service, one from combat, and one from service that had often come as an intrusive memory. For each memory, they provided 21 ratings about reliving, belief, sensory properties, reexperiencing emotions, visceral emotional responses, fragmentation, and narrative coherence. We used these ratings to examine three claims about traumatic memories: a separation of cognitive and visceral aspects of emotion, an increased sense of reliving, and increased fragmentation. There was evidence for a partial separation of cognitive judgments of reexperiencing an emotion and reports of visceral symptoms of the emotion, with visceral symptoms correlating more consistently with scores on PTSD tests. Reliving, but not fragmentation of the memories, increased with increases in the trauma relatedness of the event and with increases in scores on standardized tests of PTSD severity.
