Directed forgetting of trauma cues in adult survivors of childhood sexual abuse with and without posttraumatic stress disorder.

The authors used a directed-forgetting task to investigate whether psychiatrically impaired adult survivors of childhood sexual abuse exhibit an avoidant encoding style and impaired memory for trauma cues. The authors tested women with abuse histories, either with or without posttraumatic stress disorder (PTSD), and women with neither abuse histories nor PTSD. The women saw intermixed trauma words (e.g., molested), positive words (e.g., confident), and categorized neutral words (e.g., mailbox) on a computer screen and were instructed either to remember or to forget each word. Relative to the other groups, the PTSD group did not exhibit recall deficits for trauma-related to-be-remembered words, nor did they recall fewer trauma-related to-be-forgotten words than other words. Instead, they exhibited recall deficits for positive and neutral words they were supposed to remember. These data are inconsistent with the hypothesis that impaired survivors exhibit avoidant encoding and impaired memory for traumatic information.

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.

Memory Distortion in People Reporting Abduction by Aliens

False memory creation was examined in people who reported having recovered memories of traumatic events that are unlikely to have occurred: abduction by space aliens. A variant of the Deese/Roediger-McDermott paradigm (J. Deese. 1959; H. L. Roediger III & K. B. McDermott, 1995) was used to examine false recall and false recognition in 3 groups: people reporting recovered memories of alien abduction. people who believe they were abducted by aliens but have no memories, and people who deny having been abducted by aliens. Those reporting recovered and repressed memories of alien abduction were more prone than control participants to exhibit false recall and recognition. The groups did not differ in correct recall or recognition. Hypnotic suggestibility, depressive symptoms, and schizotypic features were significant predictors of false recall and false recognition.

Psychophysiological Responding During Script-Driven Imagery in People Reporting Abduction by Space Aliens

Is recollection of highly improbable traumatic experiences accompanied by psychophysiological responses indicative of intense emotion? To investigate this issue, we measured heart rate, skin conductance, and left lateral frontalis electro-myographic responses in individuals who reported having been abducted by space aliens. Recordings of these participants were made during script-driven imagery of their reported alien encounters and of other stressful, positive, and neutral experiences they reported. We also measured the psychophysiological responses of control participants while they heard the scripts of the abductees. We predicted that if “memories” of alien abduction function like highly stressful memories, then psycho-physiological reactivity to the abduction and stressful scripts would be greater than reactivity to the positive and neutral scripts, and this effect would be more pronounced among abductees than among control participants. Contrast analyses confirmed this prediction for all three physiological measures (ps < .05). Therefore, belief that one has been traumatized may generate emotional responses similar to those provoked by recollection of trauma (e.g., combat).

Sleep paralysis, sexual abuse, and space alien abduction

Sleep paralysis accompanied by hypnopompic (‘upon awakening’) hallucinations is an often-frightening manifestation of discordance between the cognitive/perceptual and motor aspects of rapid eye movement (REM) sleep. Awakening sleepers become aware of an inability to move, and sometimes experience intrusion of dream mentation into waking consciousness (e.g. seeing intruders in the bedroom). In this article, we summarize two studies. In the first study, we assessed 10 individuals who reported abduction by space aliens and whose claims were linked to apparent episodes of sleep paralysis during which hypnopompic hallucinations were interpreted as alien beings. In the second study, adults reporting repressed, recovered, or continuous memories of childhood sexual abuse more often reported sleep paralysis than did a control group. Among the 31 reporting sleep paralysis, only one person linked it to abuse memories. This person was among the six recovered memory participants who reported sleep paralysis (i.e. 17% rate of interpreting it as abuse-related). People rely on personally plausible cultural narratives to interpret these otherwise baffling sleep paralysis episodes.

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.

Personality profiles, dissociation, and absorption in women reporting repressed, recovered, or continuous memories of childhood sexual abuse

Women reporting either repressed, recovered, or continuous memories of childhood sexual abuse or no abuse history completed questionnaires tapping personality traits, absorption (fantasy proneness), dissociation, depression, and posttraumatic stress. Planned contrasts indicated that recovered memory participants scored higher on absorption and dissociation than did those reporting either continuous memories or no abuse history; repressed memory participants scored nonsignificantly higher than did recovered memory participants. On measures of distress, continuous memory participants were indistinguishable from nonabused participants, repressed memory participants scored highest, and recovered memory participants scored midway between continuous and repressed memory participants.

Clinical characteristics of adults reporting repressed, recovered, or continuous memories of childhood sexual abuse.

The authors assessed women and men who either reported continuous memories of their childhood sexual abuse (CSA, n = 92), reported recovering memories of CSA (n = 38), reported believing they harbored repressed memories of CSA (n = 42), or reported never having been sexually abused (n = 36). Men and women were indistinguishable on all clinical and psychometric measures. The 3 groups that reported abuse scored similarly on measures of anxiety, depression, dissociation, and absorption. These groups also scored higher than the control group. Inconsistent with betrayal trauma theory, recovered memory participants were not more likely to report abuse by a parent or stepparent than were continuous memory participants. Rates of depression and posttraumatic stress disorder did not differ between the continuous and recovered memory groups.

Effects of guided imagery on memory distortion in women reporting recovered memories of childhood sexual abuse

We tested whether having participants imagine unusual childhood events inflates their confidence that these events happened to them, and tested whether this effect is greater in women who report recovered memories of childhood sexual abuse than in women who do not. Participants were pretested on how confident they were that certain childhood events had happened to them before being asked to imagine some of these events in the laboratory. New confidence measures were readministered. Although guided imagery did not significantly inflate confidence that early childhood events had occurred in either group, the effect size for inflated confidence was more than twice as large in the control group as in the group with recovered memory. These data suggest that individuals can counteract memory distortions potentially associated with guided imagery, at least under some conditions.

Reconceptualizing the teaching team in universities: Working with sessional staff

The need for universities to find cost-effective methods for the delivery of quality programmes has seen an increase in the numbers of casual or sessional staff in universities over the past several years. The paper suggests that the existing notions of how teaching teams are constituted should be reconceptualized to encompass sessional staff. This would allow the work being undertaken by sessional staff to be openly acknowledged and recognized by the systems in which they work. The employment of sessional markers should be regarded as ‘value-adding’ to the teaching teams of the university rather than as an outsourcing of critical university functions. The framework presented here proposes that the particular professional or academic attributes contributed by sessional markers enhance the extant expertise of teams and thus potentially serve to promote the teaching-learning process. Reconceptualization of the teaching team may well require a negotiation of power relationships. Nevertheless, it is important that the contributions made by markers are recognized to ensure equity, fairness and transparency.
