Traumatic Impact Predicts Long-Term Memory for Documented Child Sexual Abuse

Autobiographical memory functioning among abused, neglected, and nonmaltreated children: the overgeneral memory effect

BACKGROUND

This investigation addresses whether there are differences in the form and content of autobiographical memory recall as a function of maltreatment, and examines the roles of self-system functioning and psychopathology in autobiographical memory processes.

METHODS

Autobiographical memory for positive and negative nontraumatic events was evaluated among abused, neglected, and nonmaltreated school-aged children.

RESULTS

Abused children's memories were more overgeneral and contained more negative self-representations than did those of the nonmaltreated children. Negative self-representations and depression were significantly related to overgeneral memory, but did not mediate the relation between abuse and overgeneral memory.

CONCLUSIONS

The meaning of these findings for models of memory and for the development of overgenerality is emphasized. Moreover, the clinical implications of the current research are discussed.

The benefit of forgetting suicidal ideation

In a sample of young adult Australians, those who had had suicidal ideation but who did not acknowledge ever having had it when asked 4 years later, were experiencing better mental health, as demonstrated by significantly better functioning on a range of psychometric measures, than those who recalled it. These results are consistent with several recent reports and indicate that forgetting painful events such as suicidal ideation is an adaptive defense mechanism. This has implications in terms of therapy focusing on contemporaneous events and the future, rather than on the past.

Are memories for sexually traumatic events "special"? A within-subjects investigation of trauma and memory in a clinical sample

According to a long-standing clinical tradition, sexually traumatic experiences are processed and recalled differently from other experiences, often leading to memory impairment. In this study, we compared the characteristics of traumatic memories for sexual violence and two other types of emotional experiences. N=44 women recruited from a local sexual trauma agency were asked to recall and describe three autobiographical events: sexual abuse/assault, a non-sexual trauma, and a positive emotional event. The characteristics of the three memory types were compared on both subjective and objective measures. Further, the potential influences of level of traumatic impact and dissociation were assessed. Results indicated that memories for sexual trauma were not impaired or fragmented relative to other memories. Instead, memories for sexual trauma were associated with a remarkably high level of vividness, detail, and sensory components. Further, high levels of traumatic impact were not associated with memory impairment. Implications for the ongoing traumatic memory debate are discussed.

Memory, maternal representations, and internalizing symptomatology among abused, neglected, and nonmaltreated children

A depth-of-processing incidental recall task for maternal-referent stimuli was utilized to assess basic memory processes and the affective valence of maternal representations among abused (N = 63), neglected (N = 33), and nonmaltreated (N = 128) school-aged children (ages 8-13.5 years old). Self-reported and observer-rated indices of internalizing symptoms were also assessed. Abused children demonstrated impairments in recall compared to neglected and nonmaltreated children. Although abused, neglected, and nonmaltreated children did not differ in valence of maternal representations, positive and negative maternal schemas related to internalizing symptoms differently among subgroups of maltreated children. Valence of maternal schema was critical in differentiating those with high and low internalizing symptomatology among the neglected children only. Implications for clinical intervention and prevention efforts are underscored.

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.

The scars of memory: a prospective, longitudinal investigation of the consistency of traumatic and positive emotional memories in adulthood

We conducted a prospective study with individuals who first described their memories of both a recent traumatic and a highly positive emotional experience in 2001-2002. Of the 49 subjects interviewed after 3 months, 29 were re-interviewed after 3.45 to 5.0 years. Subjects answered questions from a 12-item consistency questionnaire (maximum possible score of 36), rated the qualities of their memories, and completed questionnaires concerning the impact of the trauma. Results indicated that traumatic memories (including memories for violence) were highly consistent (M= 28.04) over time relative to positive memories (M= 17.75). Ratings of vividness, overall quality, and sensory components declined markedly for positive memories but remained virtually unchanged for traumatic memories. The severity of traumatic symptoms diminished over time and was unrelated to memory consistency. These findings contribute to understanding of the impact of trauma on memory over long periods.

The value of forgetting suicidal thoughts and behavior

This is a prospective longitudinal study examining recollections of suicidal content and correlates of accurate and inaccurate recollection. A primarily at-risk group of young adults (N = 78) who were initially assessed for suicidal ideation and behavior in adolescence, were asked to recall whether they had reported sui- cidal ideation or behavior about six years earlier. In recalling the previous inter- view, the majority of the participants provided consistent reports. However, with regard to those who had previously reported suicidal ideation or behavior, 38% failed to recall prior adolescent suicidal reports. Those who provided accurate reports of prior suicidal content were more symptomatic and were functioning more poorly than those who failed to recall past suicidal content. The implications for clinical assessment practices, research, and theory development are discussed.

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.

Relationship to perpetrator, disclosure, social reactions, and PTSD symptoms in child sexual abuse survivors

This research examined victim relationship to the perpetrator, disclosure characteristics, social reactions, and PTSD in adult survivors' of child sexual abuse (CSA) identified in a convenience sample of 733 college students. Results indicated that relationship to the perpetrator was related to CSA characteristics and outcomes. More negative reactions such as disbelief were observed for those victimized by relatives compared with acquaintance and stranger victims, especially for those disclosing in childhood. Victims of relatives had more PTSD symptoms if they delayed disclosure, received more negative reactions in childhood, and engaged in self-blame at the time of the abuse. Results are discussed in the context of Freyd's (1996) betrayal trauma theory, in order to better understand the traumatic impact of CSA.

Children's basic memory processes, stress, and maltreatment

Building upon methods and research utilized with normative populations, we examine extant assumptions regarding the effects of child maltreatment on memory. The effects of stress on basic memory processes is examined, and potential neurobiological changes relevant to memory development are examined. The impact of maltreatment-related sequelae (including dissociation and depression) on basic memory processes as well as false memories and suggestibility are also outlined. Although there is a clear need for additional research, the investigations that do exist reveal that maltreated children's basic memory processes are not reliably different from that of other, nonmaltreated children.

Survivors of Childhood Sexual Abuse Diagnosed with Cancer

The incidence of survivors of childhood sexual abuse (CSA) diagnosed with cancer is unknown. It is estimated that one in three women and one in six men in the United States are survivors of CSA. Survivors of CSA diagnosed with cancer are presented with multiple and potentially accumulating traumas. The re-traumatizing nature of a cancer diagnosis and treatment affects all elements of the CSA survivor's care and may impede her/his treatment. To date, the impact of CSA on the medical treatment of people with cancer has been unexplored with the existing studies on female survivors of CSA with cancer focusing on the post-treatment experience and their higher incidence of sexual dysfunction. This article describes the impact of CSA on the cancer treatment of 18 survivors of CSA and the clinical interventions used to address the unique psychosocial needs of this population. Anecdotal information suggests that the survivors of CSA may find aspects of the cancer experience reminiscent of their history of abuse. All 18 survivors of CSA experienced distressing memories of their abuse during their cancer treatment. Fifteen CSA survivors presented traumatic memories that were inaccessible to conscious thought processes prior to their cancer diagnosis. Psychodynamic interventions address issues of disruption in the cancer treatment, non-adherence, and difficulties in relationships with the health care team. Containment of intense affect and distressing thoughts rather than exploration improved CSA survivors' adherence with cancer treatments. The acquisition of self-comforting skills helped CSA survivors feel less re-victimized by their cancer experience. The establishment of an environment of internal and external safety improved communication with the health care team. Health care/psychosocial clinicians' awareness and use of appropriate interventions can minimize the affects of re-traumatization and enhance the CSA survivor's treatment experience.

[The influence of cognitive abilities, age and characteristics of their sexual abuse experience on the statement of the presumed victims]

OBJECTIVE

The goal of the present study was to examine the effects of children's age, cognitive abilities and the characteristics of their sexual abuse experience on the quantity of details revealed about the sexual abuse in an investigative interview as a function of the type of questions asked. METHOD VERSION: Transcripts of 37 investigative interviews conducted with children between 6 and 12 years of age were analyzed according to the type of interviewer questions used and the quantity of details given by the child. The children's cognitive abilities were measured using the vocabulary, information and block design subtests of the WISC-III.

RESULTS

Results of multiple regression analyses indicate that children's age and verbal abilities as well as their relationship with the perpetrator explain 50% of the variance of the mean number of details obtained from the child following open-ended interviewer questions.

CONCLUSION

The results of this study suggest that the quantity of details obtained during an investigative interview is influenced not only by children's age but also by their verbal skills and the child-perpetrator relationship.

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.

Traumatic memories are not necessarily accurate memories

Some therapists, as well as other commentators, have suggested that memories of horrific trauma are buried in the subconscious by some special process, such as repression, and are later reliably recovered. We find that the evidence provided to support this claim is flawed. Where, then, might these memory reports come from? We discuss several research paradigms that have shown that various manipulations can be used to implant false memories--including false memories for traumatic events. These false memories can be quite compelling for those who develop them and can include details that make them seem credible to others. The fact that a memory report describes a traumatic event does not ensure that the memory is authentic.

Wailing Babies in Her Wake

The scientific study of child witnesses has influenced both developmental science and jurisprudence concerning children. Focusing on the author's own studies, 4 categories of research are briefly reviewed: (a) children's eyewitness memory and suggestibility; (b) memory for traumatic events in childhood; (c) disclosure of child sexual abuse; and (d) experiences of child victim/witnesses within the legal system. Implications for psychology and for legal practice are discussed.
