Abstract
Imagination inflation happens when a person's subjective confidence that an event has occurred increases after they imagine it occurring. In this project, our primary aim is to test whether memory distrust is related to the imagination inflation effect in people who are aware of the discrepancies between their own memories and what they have imagined. Our secondary purpose is to investigate whether the influence of memory distrust on imagination inflation is moderated by traits that are described as disengagement from reality and to test whether memory distrust mediates the relationship between self-esteem and imagination inflation. In a three-step procedure, participants (N = 300) will assess their confidence that a list of childhood events happened to them; then, they will imagine three of these events and reassess their confidence. Half of the participants will undergo a memory distrust induction procedure. In order to sensitize participants to discrepancies, some of them will be given cues about the source and/or perspective of the imagined events.

Abstract
BACKGROUND Childhood abuse has been increasingly recognized as a risk factor for eating disorder symptoms. Additionally, it has been demonstrated that childhood abuse may lead to identification with the aggressor, an automatic defensive process, to survive the abuse. Although it has been clinically implied, the role of identification with the aggressor as a potential mechanism underlying the relation between childhood abuse and eating disorder symptoms has not yet been empirically explored. OBJECTIVE This study examines the role of identification with the aggressor as mediator in the association between history of childhood abuse and eating disorder symptoms among adults. PARTICIPANTS AND METHODS A convenience sample of 198 participants completed self-report questionnaires assessing history of childhood abuse, eating disorder symptoms, and the various facets of identification with the aggressor. RESULTS Severity of childhood abuse was significantly associated with shape and weight overevaluation, body dissatisfaction, and binge eating, as well as with all components of identification with the aggressor. In addition, almost all components of identification with the aggressor were significantly associated with eating disorder symptoms. Finally, identifying with the perpetrator's aggression mediated the association between childhood abuse and eating disorder symptoms. CONCLUSIONS The findings may contribute to future clinical interventions by illuminating identification with the aggressor as an important aspect in treating eating disorders. Understanding the pervasive effects of identification with the aggressor on survivors' self and their interactions with others may point to the significance of the therapeutic relationship, through which survivors can reprocess and weaken its detrimental effects.

Abstract
Interindividual differences in music-related reward have been characterized as involving five main facets: musical seeking, emotion evocation, mood regulation, social reward, and sensory-motor. An interesting concept related to how humans decode music as a rewarding experience is music transcendence or absorption (i.e., music-driven states of complete immersion, including momentary loss of self-consciousness or even time-space disorientation). Here, we investigated the relation between previously characterized facets of music reward and individual differences in music absorption. A first sample of participants (N = 370) completed both the Barcelona Music Reward Questionnaire (BMRQ) and the Absorption in Music Scale (AIMS). Results showed that both constructs were highly interrelated (r = 0.78, p < 0.001), indicating that higher music reward sensitivity is associated with a greater tendency to music-related absorption states. In addition, four items from the AIMS were identified as suitable to be added to an extended version of the BMRQ (eBMRQ). A second sample (N = 550) completed the eBMRQ for a validation study. Exploratory and confirmatory factor analyses on the whole sample (N = 920) showed the reliable psychometric properties of the eBMRQ and suggested that taking into account an absorption facet could contribute to a better characterization of individual differences in the sensitivity to experience music-related reward and pleasure.

Abstract
For more than 30 years, the posttraumatic model (PTM) and the sociocognitive model (SCM) of dissociation have vied for attention and empirical support. We contend that neither perspective provides a satisfactory account and that dissociation and dissociative disorders (e.g., depersonalization/derealization disorder, dissociative identity disorder) can be understood as failures of normally adaptive systems and functions. We argue for a more encompassing transdiagnostic and transtheoretical perspective that considers potentially interactive variables including sleep disturbances; impaired self-regulation and inhibition of negative cognitions and affects; hyperassociation and set shifts; and deficits in reality testing, source attributions, and metacognition. We present an overview of the field of dissociation, delineate uncontested and converging claims across perspectives, summarize key multivariable studies in support of our framework, and identify empirical pathways for future research to advance our understanding of dissociation, including studies of highly adverse events and dissociation. Expected final online publication date for the Annual Review of Clinical Psychology, Volume 18 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract
The term dissociation is often used to refer to a diverse range of psychological symptoms, including perceptual impairments, emotional detachment, and memory fragmentation. In the present study, we examined whether there was a relation between participants' self-reports of dissociative experiences and their memory performance in the Deese-Roediger-McDermott (DRM) paradigm-a laboratory-based procedure that is frequently used to investigate false memory. University students (N = 298) completed the Dissociative Experiences Scale (DES) and the Traumatic Life Events Questionnaire (TLEQ). Participants were also administered a standardised intelligence test (Shipley-2), and they were tested in the DRM paradigm. Overall, experiencing trauma and dissociation, as well as lower levels of cognitive ability, were associated with higher false memory. These findings are discussed in the context of the activation monitoring theory of DRM false memory.

Abstract
In early modern Scotland, several visionaries experienced vivid relationships with spirits. This paper analyses their experiences historically, with the aid of modern scholarship in medicine, psychology and social science. Most of the visionaries were women. Most of their spirit-guides were fairies or ghosts. There could be traumas in forming or maintaining the relationship, and visionaries often experienced spirit-guides as powerful, capricious and demanding. It is argued that some visionaries experienced psychotic conditions, including psychosomatic injuries, sleepwalking, mutism and catatonia. Further conditions related to visionary experience were not necessarily pathological, notably fantasy-proneness and hallucinations. Imaginary companions and parasocial relationships are discussed, as are normality, abnormality and coping strategies. There are concluding reflections on links between culture and biology.

Abstract
This paper presents the first systematic case-control study of correlates of mass psychogenic illness (MPI) in an adolescent school population. MPI is generally construed as a dissociative phenomenon spread by social contagion to individuals who are prone to dissociation. We sought to test if the correlates of dissociative experiences most commonly proposed in the literature could predict caseness among students affected by episodes of mass psychogenic illness occurring in schools in Nepal. We assessed 194 cases and 190 controls (N = 384) of ages 11-18 years from 12 public schools. Cases and controls were comparable on all demographic variables, except for family configuration, with nuclear families more common among those affected. In bivariate comparisons, caseness was associated with childhood physical neglect and abuse, as well as living in nuclear families, peritraumatic dissociation, dissociative tendencies, and depressive and post-traumatic stress symptoms. Hypnotizability emerged as the strongest correlate of psychogenic illness among the cognitive and personality trait variables. However, in multivariable logistic regression, the correlates of dissociation did not predict caseness, suggesting that they do not adequately account for the phenomenon of mass psychogenic illness. An ad-hoc Classification and Regression Trees analysis showed that if an adolescent was highly hypnotizable and reported high rates of peritraumatic dissociative experiences, then there was a 73% probability of being a case in a mass psychogenic illness episode. Future studies involving other psychological, social and cultural factors, as well as school- and family-related factors are needed to understand the correlates of mass psychogenic illness and guide prevention and intervention.

Abstract
Dissociation is a lack of information integration resulting from a process that ranges on a continuum from normative experiences (e.g., daydreaming) to a pervasive traumatic response involving alterations and/or fragmentation in mental processes such as memory, emotion, and perception. Perceived coping self-efficacy (CSE) is a cognitive appraisal ability utilized to regulate internal and external stressors that arise from traumatic events, and is crucial for effective adaptation after extreme stress or trauma. Thus, CSE may be a critical component in decreasing dissociative experiences following a traumatic event. In the present study, 136 undergraduate students (M age = 22.36 years, SD = 6.27; 81% female, 69.1% Caucasian, 77.2% attended some college) completed self-report measures of trauma, dissociation, and coping self-efficacy. All measures were completed by the same participants at two different time points (Time 1 and Time 2) two months apart; all participants reported a history of exposure to at least one Criterion A traumatic event (according to the DSM-5) at Time 1. We hypothesized that CSE for posttraumatic coping demands at Time 2 would mediate the relationship between dissociation at Time 1 and dissociation at Time 2, and subsequently found evidence of significant mediation, 95% CI [.02, .18]. These findings suggest that initial levels of persistent dissociation negatively predict CSE, which in turn directly and negatively influence persistent dissociation at a later time point. This highlights how CSE may serve as a protective factor against persistent dissociation.

Abstract
While peritraumatic dissociation has been identified as a predictor of posttraumatic stress disorder, it may also have some protective aspect. The study uses experience sampling methods to assess acute dissociation reactions during conflict, and to investigate these reactions as predictors of subsequent posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG). During the 2014 Israel-Gaza conflict, Israeli civilians (n = 96) exposed to rocket fire gave twice-daily experience sampling method (ESM) reports of dissociation symptoms for 30 days via mobile phone. PTSS and PTG were assessed two months later. A mixed effects random intercepts and slopes model estimated acute dissociation reactions. Individual slope coefficients for acute dissociative reactivity were entered as predictors of subsequent PTSS and PTG in regression analyses investigating linear and curvilinear associations. Exposure to sirens elicited acute dissociation reactions. Dissociative reactivity gradually reduced over the conflict. Higher acute dissociative reactivity during conflict predicted PTSS in a curvilinear manner (inverted U) and PTG in a positive linear manner two months later. The current study provides an important and novel contribution to the field by using ESM methods to assess peritraumatic dissociation, and in demonstrating that peritraumatic dissociation may be both adaptive and maladaptive, which has implications for risk assessment and clinical practice.

Abstract
This study uses conjuring to investigate the effects of suggestion, social influence, and paranormal belief upon the accuracy of eyewitness testimony for an ostensibly paranormal event. Participants watched a video of an alleged psychic seemingly bending a metal key by the power of psychokinesis. Half the participants heard the fake psychic suggest that the key continued to bend after it had been put down on a table and half did not. Additionally, participants were exposed to either a negative social influence (a stooge co-witness reporting that the key did not continue to bend), no social influence, or a positive social influence (a stooge co-witness reporting that the key did continue to bend). Participants who were exposed to the verbal suggestion were significantly more likely to report that the key continued to bend. Additionally, more participants reported that the key continued to bend in the positive social influence condition compared to the other two social influence conditions. Finally, believers in the paranormal were more likely to report that the key continued to bend than non-believers.

Abstract
This study explored distinctions between spontaneous and deliberate dissociative states in 335 military personnel exposed to stressful survival training. Participants completed the Clinician-Administered Dissociative States Scale (CADSS) after a stressful mock-captivity event. They were also asked to indicate whether the dissociative experiences just happened (i.e., spontaneous), or whether they chose to have them happen (i.e., deliberate); and whether they appraised the dissociative experience as helpful (i.e., facilitative) or hurtful (i.e., debilitative) to their ability to cope with the stressful event. A majority (95.4%) endorsed dissociative states during stress. More than half (57.4%) described dissociative experiences as spontaneous, 13.0% as deliberate, and 29.5% endorsed neither. In Special Forces soldiers only, those who endorsed facilitative dissociation exhibited higher total CADSS scores than those who endorsed debilitative dissociation. Seventy-three percent of spontaneous dissociators described the experience as debilitative to coping with stress; conversely, 76% of deliberate dissociators said these experiences facilitated coping with stress. Individuals with prior trauma exposure tended to appraise dissociative states as more debilitative to coping. This research may enhance the fidelity of studies of dissociation constructs and may offer pivot points for prevention and treatment of stress-related disorders.

Abstract
The current dispute regarding the existence of repression has mainly focused on whether people remember or forget trauma. Repression, however, is a multidimensional construct, which, in addition to the memory aspect, consists of pathogenic effects on adjustment and the unconscious. Accordingly, in order to arrive at a more accurate decision regarding the existence of repression, studies relevant to all three areas are reviewed. Moreover, since psychoanalysis regards repression as a key factor in accounting for the development and treatment of neurotic disorders, relevant research from these two domains are also taken into account. This comprehensive evaluation reveals little empirical justification for maintaining the psychoanalytic concept of repression.

Abstract
Recently, Gerrie, Belcher, and Garry (2006) found that, when participants watch an event with parts missing, they falsely claim to have seen the missing parts--but they were more likely to claim they had seen less crucial parts than more crucial parts. Their results fit with a source-monitoring framework (SMF; Johnson, Hashtroudi, & Lindsay, 1993) explanation of false memories. In this paper we used individual differences in working memory capacity (WMC) to examine the SMF explanation of false memories for missing aspects of events. An accumulating body of research suggests that WMC is strongly related to controlling attention, including the ability to distinguish between sources of information. The primary purpose of the present study was to examine whether people with larger WMC are better able to ward off false memories for missing information than those with a smaller WMC. We showed that higher WMC reduced false recognition of crucial information, but did not change false recognition of noncrucial information. Additionally, we found that WMC had little effect on participants' subjective experience of true and false recognition of events, regardless whether the information was crucial or not. These results provide further evidence that people's WMC is related to their source-monitoring ability.

Abstract
This study indexed the relationship between acute stress disorder (ASD) and subsequent posttraumatic stress disorder (PTSD) in injured children. Consecutive children between 7-13 years admitted to a hospital after traumatic injury (n = 76) were assessed for ASD. Children were followed up 6-months posttrauma (n = 62), and administered the PTSD Reaction Index. Acute stress disorder was diagnosed in 10% of patients, and 13% satisfied criteria for PTSD. At 6-months posttrauma, PTSD was diagnosed in 25% of patients who were diagnosed with ASD. Acute stress reactions that did not include dissociation provided better prediction of PTSD than full ASD criteria. These findings suggest that the current ASD diagnosis is not optimal in identifying younger children who are high risk for PTSD development.

The present study examined whether individuals with full-blown memories of highly implausible events are prone to commit source monitoring errors. Participants reporting previous-life memories and those without such memories completed a false fame task. This task provides an index of source monitoring errors (i.e., misclassifying familiar non-famous names as famous names). Participants with previous-life memories had a greater tendency to judge the names of previously presented non-famous people as famous than control participants. The two groups did not differ in terms of correct recognition of new non-famous names and famous names. Although dissociation, cognitive failures, sleep-related experiences, depressive symptoms, and signs of psychological distress were all significantly higher in participants with previous-life memories than in controls, these variables did not predict the false fame illusion.

Abstract
As falsas memórias são lembranças de eventos que na realidade nunca ocorreram. Porém, a pergunta que surge é quais características e traços de personalidade poderiam influenciar na suscetibilidade a esse tipo de distorção de memória. A fim de investigar as diferenças individuais e falsas memórias, o presente estudo testou em 150 estudantes universitários o efeito do traço de personalidade neuroticismo (baseado no modelo dos Cinco Grandes Fatores) na suscetibilidade às falsas memórias. Para isso foram utilizados como instrumentos a Escala Fatorial de Ajustamento Emocional/Neuroticismo e a versão brasileira do procedimento das Listas de Palavras Associadas, contendo palavras de cunho neutro e emocional (positivo e negativo). Os resultados mostraram que pessoas com alto neuroticismo apresentaram maior número de falsas memórias e uma melhor lembrança para palavras de valência emocional negativa.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
In psychiatric literature, dissociative reactions at the time of a traumatic event (i.e., peritraumatic dissociation) are considered to be risk factors for the development of post-traumatic stress disorder (PTSD). In this article, we critically review research concerned with the link between peritraumatic dissociation and PTSD. Our main point is that studies in this area heavily rely on retrospective reports of dissociative reactions during the trauma. We argue that this methodology has important limitations since people in general and PTSD patients in particular find it difficult to give accurate descriptions of past emotional states. Restrictive factors that play a role in this context have to do with forgetting, attribution, and malingering.

Abstract
Over the past decade, a contentious debate regarding delayed memories of childhood sexual abuse (CSA) has existed. In order to address this debate, 240 female participants completed questions about CSA, the Dissociative Experience Scale (Bernstein & Putnam, 1986), Perceived Emotional Closeness with Perpetrator Scale (Schultz, Passmore, & Yoder, 2000), and the Gudjonsson Suggestibility Scale 2 (GSS 2) (Gudjonsson, 1987). Eighty-two (36%) reported CSA and 37% of these indicated memory disturbances for the CSA. Participants reporting memory disturbances also reported significantly higher numbers of perpetrators, chemical abuse in their families, and closer relationships with the perpetrator(s) than participants reporting no memory disturbances. Implications for clinicians working with clients reporting CSA are discussed.

Abstract
The present study was designed to assess children's memory and suggestibility in the context of ongoing child maltreatment investigations. One hundred eighty-nine 3-17-year-olds involved in evaluations of alleged maltreatment were interviewed with specific and misleading questions about an anogenital examination and clinical assessment. For the anogenital examination, children's stress arousal was indexed both behaviorally and physiologically. For all children, individual-difference data were gathered on intellectual and short-term memory abilities, general psychopathology, and dissociative tendencies. Interviewers' ratings were available for a subset of children concerning the amount of detail provided in abuse disclosures. Results indicated that general psychopathology, short-term memory, and intellectual ability predicted facets of children's memory performance. Older compared to younger children evinced fewer memory errors and greater suggestibility resistance. Age was also significantly related to the amount of detail in children's abuse disclosures. Neither dissociation nor stress arousal significantly predicted children's memory. Implications for understanding maltreated children's eyewitness memory are discussed.
