Associations between Thematic Content and Memory Detail in Trauma Narratives

This study examined whether thematic content (e.g., fear, anger, alienation, self‐blame, and spirituality) in trauma narratives predicted memory detail. Trauma‐specific memory models suggest that trauma narrative themes are associated with much sensory detail; general autobiographical memory models suggest that themes are associated with little context detail. Seventy‐one narratives from a diverse community sample exposed to a variety of traumatic events (e.g., sexual assault, natural disasters) were coded for themes and detail. Analyses controlled for narrative length, childhood or adulthood occurrence, self‐reported post‐traumatic stress disorder, depression and dissociation symptoms. Fear themes were associated with greater sensory detail; anger and spirituality themes were associated with less context detail. Findings support a link between thematic content and detail, and may partially explain why details in memory for traumatic events sometimes appear better and other times worse than memory for other events. Memory models may benefit from specification based on themes in trauma narratives. Copyright © 2013 John Wiley & Sons, Ltd.     

Forgetting trauma stimuli

Previous work reported in this journal suggested that the cognitive capacities of high dissociators are impaired under conditions of focused (selective) attention, but not under conditions of divided attention, compared with the cognitive capacities of low dissociators. Using a directed-forgetting paradigm, the current study demonstrated that under divided-attention demands, high dissociators have impaired memory for words associated with trauma (e.g., incest) but not for neutral words, as compared with low dissociators. In addition, high dissociators reported significantly more trauma history and significantly more betrayal trauma (abuse by a caregiver) than low dissociators. These results are consistent with the proposal that dissociation may aid individuals with histories of betrayal traumas to keep threatening information out of awareness.     

Dissociative Tendencies, Attention, and Memory

Two groups of college students were selected on the basis of their scores on the Dissociative Experiences Scale (DES). The high-DES group (score > 20, M = 29.6; n = 54) and low-DES group (score < 10, M = 5.1; n = 54) both completed the standard and a new dual-task version of the Stroop ink-naming task with xs (baseline condition) and color, neutral, and emotionally charged words. Free recall results indicated that high-DES participants remembered fewer emotionally charged words than low-DES participants. We found a crossover interaction for Stroop interference: High-DES participants showed more interference (conflicting color — baseline latency for ink naming) in a selective-attention Stroop task and less interference in the dual-task Stroop task. The interaction between attentional context and dissociation for Stroop interference and the free recall results are consistent with a cognitive-environments view of dissociative tendencies. In this view, dissociative tendencies, which have been otherwise speculated to be largely deleterious, can be advantageous in certain contexts.     

What's in a name for memory errors? Implications and ethical issues arising from the use of the term "false memory" for errors in memory for details

The term "false memories" has been used to refer to suggestibility experiments in which whole events are apparently confabulated and in media accounts of contested memories of childhood abuse. Since 1992 psychologists have increasingly used the term "false memory" when discussing memory errors for details, such as specific words within lists. Use of the term to refer to errors in details is a shift in language away from other terms used historically (e.g., "memory intrusions"). We empirically examine this shift in language and discuss implications of the new use of the term "false memories." Use of the term presents serious ethical challenges to the data-interpretation process by encouraging over-generalization and misapplication of research findings on word memory to social issues.     

To Add Insight to Injury: Childhood Abuse,Abuse Perceptions,and the Emotional and Physical Health of Young Adults

Although childhood abuse is strongly associated with psychological difficulties, survivors may not perceive their experiences as abusive. Depression, anxiety, dissociation, and physical health complaints may decrease perceptions of abuse and may also be exacerbated by individuals' abuse perceptions. The current study examined abuse perceptions, abuse experiences, and current symptoms among 185 university students. Ninety-six participants repeated the study 1–2 years later. At Time 1, self-labeling as “abused” or “maltreated” was not related to psychological or physical health symptoms. At Time 2, self-labeling as “abused” or “maltreated” was positively related to depression, anxiety, and dissociation. Results indicate that abuse perceptions may change over time and may be connected with emotional and physical symptoms.
