ABSTRACT
There is little published research on dissociative experiences among transgender people, and none from an in-depth qualitative perspective. In-depth, open-ended interviews (N = 7, 6 trans women, 1 trans man) were conducted to explore how dissociation is experienced (particularly among trans women) and its possible relation to negative emotions. There were several similarities across the dissociative experiences described by participants: six felt themselves disconnected from their body as a whole (in contrast to feeling disconnected to a specific body part), and from the world around them and/or themselves. Four acted out different personalities, and five felt emotionally numb when they were dissociating. Six participants described that their dissociation lessened after they started hormone therapy. Respondents tended to distinguish between dysphoric and dissociative experiences: dysphoric phenomena were more clearly distressful while dissociative ones were more emotionally numb.
ABSTRACT
A depersonalization episode occurred unexpectedly during an electroencephalogram (EEG) recording for a study. Experience reports tracked the time course of this event and, in conjunction, with EEG data, were analyzed. The source activity across canonical frequency bands was analyzed across four periods ended by retrospective experience reports (depersonalization was reported in the 2nd period). Delta and theta decreases occurred across all time periods with no relation to reported events. Theta and alpha increases occurred in right secondary visual areas following depersonalization, which also coincided with surges in beta and gamma. The largest increases occurred in bilateral fronto-polar and medial prefrontal cortex, followed by inferior left lateral fronto-insula-temporal cortices and right secondary visual cortex. A high frequency functional network with a principal hub in left insula closely overlapped inferior left cortical gamma band-power increases. Bilateral frontal increases in gamma are consistent with studies of dissociation. We interpret gamma and later beta, alpha, and theta band increases as arising from the generation of visual priors, in the absence of precise visual signals, which constrain interoceptive and proprioceptive predictions to reestablish a stable sense of physiological-self. Beta showed local increases following the pattern of gamma but showed no changes in functional connectivity.

PURPOSE: To evaluate the neurophenomenology of automatic writing (AW) in a spontaneous automatic writer (NN) and four high hypnotizables (HH). METHODS: During fMRI, NN and the HH were cued to perform spontaneous (NN) or induced (HH) AW, and a comparison task of copying complex symbols, and to rate their experience of control and agency. RESULTS: Compared to copying, for all participants AW was associated with less sense of control and agency and decreased BOLD signal responses in brain regions implicated in the sense of agency (left premotor cortex and insula, right premotor cortex, and supplemental motor area), and increased BOLD signal responses in the left and right temporoparietal junctions and the occipital lobes. During AW, the HH differed from NN in widespread BOLD decreases across the brain and increases in frontal and parietal regions. CONCLUSIONS: Spontaneous and induced AW had similar effects on agency, but only partly overlapping effects on cortical activity.

Alterations of the sense of self induced by meditation include an increased sense of boundarylessness. In this study, we investigated behavioural and functional magnetic resonance imaging correlates of trait self-boundarylessness during resting state and the performance of two experimental tasks. We found that boundarylessness correlated with greater self-endorsement of words related to fluidity and with longer response times in a math task. Boundarylessness also correlated negatively with brain activity in the posterior cingulate cortex/precuneus during mind-wandering compared to a task targeting a minimal sense of self. Interestingly, boundarylessness showed quadratic relations to several measures. Participants reporting low or high boundarylessness, as compared to those in between, showed higher functional connectivity within the default mode network during rest, less brain activity in the medial prefrontal cortex during self-referential word processing, and less self-endorsement of words related to constancy. We relate these results to our previous findings of a quadratic relation between boundarylessness and the sense of perspectival ownership of experience. Additionally, an instruction to direct attention to the centre of experience elicited brain activation similar to that of meditation onset, including increases in anterior precentral gyrus and anterior insula and decreases in default mode network areas, for both non-meditators and experienced meditators.
ABSTRACT
This interview with Professor Irving Kirsch took place in late August, 2022. He recently turned 80 years old and agreed to focus his interview on topics and areas that illustrate his influence on the field of hypnosis. Professor Kirsch discusses the influences that shaped him as a person and scientist; what unites his theoretical and research work on hypnosis, placebo, and antidepressants. He also addresses the importance of response expectancies, why clinicians should learn hypnosis and what he considers the source of his greatest personal and professional fulfillments.

Individuals who sleep poorly report spending more time mind wandering during the day. However, past research has relied on self-report measures of sleep or measured mind wandering during laboratory tasks, which prevents generalization to everyday contexts. We used ambulatory assessments to examine the relations between several features of sleep (duration, fragmentation, and disturbances) and mind wandering (task-unrelated, stimulus-independent, and unguided thoughts). Participants wore a wristband device that collected actigraphy and experience-sampling data across 7 days and 8 nights. Contrary to our expectations, task-unrelated and stimulus-independent thoughts were not associated with sleep either within- or between-persons (n = 164). Instead, individual differences in unguided thoughts were associated with sleep disturbances and duration, suggesting that individuals who more often experience unguided train-of-thoughts have greater sleep disturbances and sleep longer. These results highlight the need to consider the context and features of mind wandering when relating it to sleep.

BACKGROUND: Studies have reported elevated rates of dissociative symptoms and comorbid dissociative disorders in functional neurological disorder (FND); however, a comprehensive review is lacking. AIMS: To systematically review the severity of dissociative symptoms and prevalence of comorbid dissociative disorders in FND and summarise their biological and clinical associations. METHOD: We searched Embase, PsycInfo and MEDLINE up to June 2021, combining terms for FND and dissociation. Studies were eligible if reporting dissociative symptom scores or rates of comorbid dissociative disorder in FND samples. Risk of bias was appraised using modified Newcastle-Ottawa criteria. The findings were synthesised qualitatively and dissociative symptom scores were included in a meta-analysis (PROSPERO CRD42020173263). RESULTS: Seventy-five studies were eligible (FND n = 3940; control n = 3073), most commonly prospective case-control studies (k = 54). Dissociative disorders were frequently comorbid in FND. Psychoform dissociation was elevated in FND compared with healthy (g = 0.90, 95% CI 0.66-1.14, I2 = 70%) and neurological controls (g = 0.56, 95% CI 0.19-0.92, I2 = 67%). Greater psychoform dissociation was observed in FND samples with seizure symptoms versus healthy controls (g = 0.94, 95% CI 0.65-1.22, I2 = 42%) and FND samples with motor symptoms (g = 0.40, 95% CI -0.18 to 1.00, I2 = 54%). Somatoform dissociation was elevated in FND versus healthy controls (g = 1.80, 95% CI 1.25-2.34, I2 = 75%). Dissociation in FND was associated with more severe functional symptoms, worse quality of life and brain alterations. CONCLUSIONS: Our findings highlight the potential clinical utility of assessing patients with FND for dissociative symptomatology. However, fewer studies investigated FND samples with motor symptoms and heterogeneity between studies and risk of bias were high. Rigorous investigation of the prevalence, features and mechanistic relevance of dissociation in FND is needed.
ABSTRACT
OBJECTIVE: Peritraumatic dissociation (PD) and coping strategies (CS) around the time of trauma are significant predictors of acute and long-term posttraumatic symptomatology (PTS), but it is unclear how they relate to each other. The aim of this study was to examine their association using a nationwide, representative sample following the September 11 attacks in the United States (N = 3,134). METHOD: We used exploratory and confirmatory network analyses to estimate reliable associations between PD and CS, as well as looking at those variables as predictors of PTS at 2, 6, and 12 months after the attack. RESULTS: Analyses showed that: (a) PD formed 3 factors (alterations of consciousness, depersonalization, and compartmentalization) distinct from coping strategies; (b) PD related only to some CS; (c) coping through denial had a particularly strong link to alterations of consciousness among adults. Both altered consciousness and denial predicted PTS significantly 2, 6, and 12 months after the attack, with altered consciousness being the stronger predictor (and a better predictor of PTS than other types of PD). For teens, the only significant link between PD and CS was for compartmentalization and substance abuse. CONCLUSION: PD and CS were related in adults and contributed independently to later PTS. Future research should evaluate longitudinally the interactions between specific types of PD and CS. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
ABSTRACT
Accumulating evidence suggests that individuals with greater executive resources spend less time mind wandering. Independent strands of research further suggest that this association depends on concentration and a guilty-dysphoric daydreaming style. However, it remains unclear whether this association is specific to particular features of executive functioning or certain operationalizations of mind wandering, including task-unrelated thoughts (TUTs, comprising external distractions and mind wandering) and stimulus-independent and task-unrelated thoughts (SITUTs, comprising mind wandering only). This study sought to clarify these associations by using confirmatory factor analysis to compute latent scores for distinct executive functions based on nine cognitive tasks and relating them to experience sampling reports of mind wandering. We expected that individuals with greater executive control (specifically updating) would show a stronger reduction in SITUTs as momentary concentration and guilty-dysphoric style increase. A bifactor model of the cognitive battery indicated a general factor (common executive functioning) and ancillary factors (updating and shifting). A significant interaction between updating and concentration on mind wandering was observed with mind wandering defined as TUTs, but not as SITUTs (N = 187). A post hoc analysis clarified this discrepancy by showing that as concentration increases, both external distractions and mind wandering decrease more strongly among people with greater updating. Moreover, common executive functioning predicted a more negative slope of guilty-dysphoric style on SITUTs, whereas updating and shifting predicted more positive slopes. The opposite slopes of these executive functions on daily life mind wandering may reflect a stability-flexibility trade-off between goal maintenance and goal replacement abilities.

Ernest R. Hilgard is not only one of the most important hypnosis theoreticians and researchers in history, but one the most eminent psychologists of the 20th century. This paper starts with a brief summary of his contributions to hypnosis, emphasizing his dissociation theory, and placing it within previous and later dissociation theories of hypnosis. I then transcribe an interview with him circa 1989, which I recorded with his authorization for later use, emphasizing dissociation in hypnosis. He also reminisced about historical figures in psychology.

Sweden was hit hard in the beginning of the COVID-19 pandemic with deaths per capita among the highest in Europe. The pandemic was a stressful time especially for healthcare workers caring for COVID-19 patients. Various studies have evaluated whether nurses caring for these patients had higher levels of acute stress, but typically with measures that either used older DSM-IV criteria for Acute Stress Disorder (ASD) or general measures of acute stress. We recruited an online sample (N = 101) of nurses in Sweden from COVID-19 specialized units (ICU), Emergency (ER), and other units (Other), and asked them to answer questionnaires retrospectively to the peak of infections in Sweden. We aimed to evaluate: 1) the psychometric properties of the translation of the Stanford Acute Stress Reaction Questionnaire-II (SASRQ-II, which follows DSM-5 criteria for ASD) into Swedish, 2) whether nurses in COVID-19 units had experienced more acute stress than nurses in other units, and 3) the extent of potential acute stress disorder. The SASRQ-II evidenced good construct, convergent and divergent validity, and good reliability. It showed that ICU nurses reported significantly more acute stress than the other two groups, a difference that could not be accounted for by demographic or other variables. A retrospective diagnosis of ASD using the SASRQ-II suggested that 60% of nurses might have fulfilled ASD criteria, but no differences across groups were found.
ABSTRACT
The abeyance of self-consciousness (SC) during hypnosis has been discussed as a central aspect of hypnosis, yet dispositional SC has been very rarely evaluated as a correlate of hypnotizability. In this study (N = 328), the authors administered the Harvard Group Scale of Hypnotic Susceptibility (HGSHS), the Inventory Scale of Hypnotic Depth (ISHD), and the Self-Consciousness Scale-Revised (SCS-R). Women tended to score higher than men on the HGSHS, besides experiencing greater ISHD automaticity. The Discontinuity (with everyday experiences) subscale of the ISHD correlated with the Public Self-Consciousness scale of the SCS-R and with the Private Self-Consciousness subscale (using simple, quadratic, and cubic regressions). Being concerned about the perception of others related to experiencing hypnosis as discontinuous with everyday life, which also related to being more introspective and interested in subjectivity at the middle range of scores. The article concludes with suggestions on how to pursue the implications of these results, including testing for nonlinear relations.

This study explores how Mayan people from Guatemala and Swedes view and behave toward death. Using an interpretative phenomenological analysis, 10 participants from each culture were interviewed to elucidate the most relevant and important emerging themes. The Mayan approach to death is based on a collective perspective in which consultations with Elders, ancient traditions, and rituals help provide answer to most existential inquiries surrounding death. In contrast, the Swedish approach is based on an individualistic, rational analysis with a focus on life instead of death, but also showing openness to new perspectives on death.

Reality shifting (RS) is a trendy mental activity that emerged abruptly following the flare-up of the COVID-19 pandemic in 2020 and seems to be practiced mainly by members of the post-millennial generation. RS, described as the experience of being able to transcend one's physical confines and visit alternate, mostly fictional, universes, is discussed by many on Internet platforms. One RS forum boasts over 40,000 members and RS clips on some social media platforms have been viewed over 1.7 billion times. The experience of shifting is reportedly facilitated by specific induction methods involving relaxation, concentration of attention, and autosuggestion. Some practitioners report a strong sense of presence in their desired realities, reified by some who believe in the concrete reality of the alternate world they shift to. One of the most popular alternate universes involves environments adopted from the Harry Potter book and film series. We describe the phenomenology of RS as reported online and then compare it to related phenomena such as hypnosis, tulpamancy, dissociation, immersive and maladaptive daydreaming, and lucid dreaming. We propose a theoretical model of interactive factors giving rise to RS, and conclude that it is an important, uninvestigated emerging phenomenon and propose future research directions.
ABSTRACT
We conducted a network analysis of measures of dissociation and posttraumatic symptoms (PTS) with a varied sample of adolescents (N = 312), some of them previously exposed to war scenarios. The global measure of dissociation (A-DES) was uniquely linked to the arousal PTS symptom cluster (CRIES-13), in particular sleep problems, but not to the reexperiencing and avoidance clusters. Three of four (i.e., depersonalization/derealization, amnesia, mental partition/compartmentalization) dissociation clusters were uniquely linked to PTS severity, but not absorption. The results with the pooled groups were generally representative of both groups. The DP/DR relation to PTS was based on data from both samples, whereas the link between amnesia and partition/parts might have been driven by the normative group, although the refugee sample had significantly higher scores in those variables. The results replicate some previous findings with adult samples and suggest new paths for research and theory.
ABSTRACT
The COVID-19 pandemic has provoked generalized uncertainty around the world, with health workers experiencing anxiety, depression, burnout, insomnia, and stress. Although the effects of the pandemic on mental health may change as it evolves, the majority of reports have been web-based, cross-sectional studies. We performed a study assessing acute stress in frontline health workers during two consecutive epidemic waves. After screening for trait anxiety/depression and dissociative experiences, we evaluated changes in acute stress, considering resilience, state anxiety, burnout, depersonalization/derealization symptoms, and quality of sleep as cofactors. During the first epidemic wave (April 2020), health workers reported acute stress related to COVID-19, which was related to state anxiety. After the first epidemic wave, acute stress decreased, with no increase during the second epidemic wave (December 2020), and further decreased when vaccination started. During the follow-up (April 2020 to February 2021), the acute stress score was related to bad quality of sleep. However, acute stress, state anxiety, and burnout were all related to trait anxiety/depression, while the resilience score was invariant through time. Overall, the results emphasize the relevance of mental health screening before, during, and after an epidemic wave of infections, in order to enable coping during successive sanitary crises.

The term "retroactive avoidance" refers to a special class of effects of future stimulus presentations on past behavioral responses. Specifically, it refers to the anticipatory avoidance of aversive stimuli that were unpredictable through random selection after the response. This phenomenon is supposed to challenge the common view of the arrow of time and the direction of causality. Preliminary evidence of "retroactive avoidance" has been published in mainstream psychological journals and started a heated debate about the robustness and the true existence of this effect. A series of seven experiments published in 2014 in the Journal of Consciousness Studies (Maier et al., 2014) tested the influence of randomly drawn future negative picture presentations on avoidance responses based on key presses preceding them. The final study in that series used a sophisticated quantum-based random stimulus selection procedure and implemented the most severe test of retroactive avoidance within this series. Evidence for the effect, though significant, was meager and anecdotal, Bayes factor (BF10) = 2. The research presented here represents an attempt to exactly replicate the original effect with a high-power (N = 2004) preregistered multi-lab study. The results indicate that the data favored the null effect (i.e., absence of retroactive avoidance) with a BF01 = 4.38. Given the empirical strengths of the study, namely its preregistration, multi-lab approach, high power, and Bayesian analysis used, this failed replication questions the validity and robustness of the original findings. Not reaching a decisive level of Bayesian evidence and not including skeptical researchers may be considered limitations of this study. Exploratory analyses of the change in evidence for the effect across time, performed on a post-hoc basis, revealed several potentially interesting anomalies in the data that might guide future research in this area.

Previous studies have indicated that a sad mood and sleep deprivation increase mind wandering, but it is unclear whether these associations reflect reduced effort in concentrating on the task at hand or diminished cognitive control. In an internet-based experiment, participants completed a sleep disturbance questionnaire followed by a complex span task and a 2-back task with thought-sampling probes. Subsequently, participants underwent a positive, neutral, or negative mood induction prior to repeating the 2-back. The results (N = 504) replicated the finding of increased task-unrelated thoughts following sad mood induction, B = 0.56 (SE = 0.14), p < 0.01, d = 0.31. Unguided thoughts were increased following sad mood induction, B = 0.31 (0.13), p = 0.02, but working memory did not significantly moderate this association (p = 0.31). People reported a lower degree of trying to concentrate on the 2-back after the sad mood induction, B = -0.07 (0.04), p = 0.04, but actual performance was not affected (p = 0.46). Sleep disturbances showed small associations with task-unrelated, B = 0.23 (0.08), p < 0.01, and unguided thoughts, B = 0.32 (0.08), p < 0.01. This study strengthens the evidence that a sad mood and poor sleep relate to mind wandering.
