Cognitive simulation along with neural adaptation explain effects of suggestions: a novel theoretical framework.

Hypnosis is an effective intervention with proven efficacy that is employed in clinical settings and for investigating various cognitive processes. Despite their practical success, no consensus exists regarding the mechanisms underlying well-established hypnotic phenomena. Here, we suggest a new framework called the Simulation-Adaptation Theory of Hypnosis (SATH). SATH expands the predictive coding framework by focusing on (a) redundancy elimination in generative models using intrinsically generated prediction errors, (b) adaptation due to amplified or prolonged neural activity, and (c) using internally generated predictions as a venue for learning new associations. The core of our treatise is that simulating proprioceptive, interoceptive, and exteroceptive signals, along with the top-down attenuation of the precision of sensory prediction errors due to neural adaptation, can explain objective and subjective hypnotic phenomena. Based on these postulations, we offer mechanistic explanations for critical categories of direct verbal suggestions, including (1) direct-ideomotor, (2) challenge-ideomotor, (3) perceptual, and (4) cognitive suggestions. Notably, we argue that besides explaining objective responses, SATH accounts for the subjective effects of suggestions, i.e., the change in the sense of agency and reality. Finally, we discuss individual differences in hypnotizability and how SATH accommodates them. We believe that SATH is exhaustive and parsimonious in its scope, can explain a wide range of hypnotic phenomena without contradiction, and provides a host of testable predictions for future research.

Remember walking in their shoes? The relation of self-referential source memory and emotion recognition.

Deficits in the ability to read the emotions of others have been demonstrated in mental disorders, such as dissociation and schizophrenia, which involve a distorted sense of self. This study examined whether weakened self-referential source memory, being unable to remember whether a piece of information has been processed with reference to oneself, is linked to ineffective emotion recognition. In two samples from a college and community, we quantified the participants' ability to remember the self-generated versus non-self-generated origins of sentences they had previously read or partially generated. We also measured their ability to read others' emotions accurately when viewing photos of people in affect-charged situations. Multinomial processing tree modelling was applied to obtain a measure of self-referential source memory that was not biased by non-mnemonic factors. Our first experiment with college participants revealed a positive correlation between correctly remembering the origins of sentences and accurately recognising the emotions of others. This correlation was successfully replicated in the second experiment with community participants. The current study offers evidence of a link between self-referential source memory and emotion recognition.

Cross-validation of the ego dissolution scale: implications for studying psychedelics.

Introduction: Ego dissolution, variously called Ego-Loss, self-loss, and ego disintegration, is a hallmark of psychedelic drug use. We cross-validated the 10-item Ego Dissolution Scale, which we developed to assess ego dissolution in everyday life, and we included comparator variables that expanded our original assessment of construct validity. Methods: Undergraduate college student volunteers (N = 527) completed the measures online. Results: We replicated the original two factor structure (i.e., subfactors: Ego-Loss and Unity/connectedness with others, the world, universe), and we determined that the total score (Cronbach's α = 0.79) and subfactors (Ego-Loss = 78; Unity = 0.83) possessed adequate-to-good reliability and strong convergent validity (e.g., mindfulness, hallucination-predisposition, sleep variables, personality variables, positive/negative affect transliminality, dissociation/depersonalization), while neuroticism, social desirability did not correlate highly with ego dissolution. We identified distinct patterns of relations of measures associated with the Ego-Loss vs. Unity subfactors. Discussion: We discuss the implications of the use of the EDS for studying everyday aspects of ego dissolution, the long-term effects of psychedelic use, and the value of using the scale in conjunction with measures of the acute effects of psychedelics.

Resilience, Coping, and the Covid-19 Pandemic Across the Globe - an Update: What Have we Learned?

The SARS-CoV-2 (COVID-19) pandemic is a mass traumatic event that has universally and indiscriminately negatively affected the world. The adverse consequences of the pandemic have globally impacted psychological health and well-being via increased stressors, such as uncertainty, health anxieties, and financial instability. During the initial months of the pandemic, we (Polizzi et al., 2020) identified coping strategies that may be well-suited to address the sequelae of the pandemic. These strategies included behavioral activation, acceptance-based coping, mindfulness practice, and loving-kindness meditation. We argued that these coping skills may foster resilience and recovery during the pandemic by generating a sense of social connection, encouraging meaning-making, and enhancing feelings of control amid uncertainty. Three years later, we update our initial suggestions by providing a narrative review that considers empirical evidence collected during the pandemic to support the utility of the previously identified coping strategies as well as additional strategies. We also discuss cross-cultural similarities and differences among these strategies and how research supports their application across diverse countries and groups. Finally, we conclude by synthesizing the literature within a regulatory flexibility framework that emphasizes flexible skill implementation with respect to sensitivity to context, coping repertoires, and feedback from the environment.

Unified Protocol vs Trauma-Focused Cognitive Behavioral Therapy Among Adolescents With PTSD.

Harmful consequences of COVID-19, such as prolonged quarantine, lack of social contact, and especially loss of parents or friends, can negatively impact children and adolescents' mental health in diverse ways, including engendering posttraumatic stress symptoms. Our study is the first to compare the transdiagnostic Unified Protocol for the Treatment of Emotional Disorders in Adolescents (UP-A; Ehrenreich et al., 2009; Ehrenreich-May et al., 2017) with Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) in terms of outcomes related to PTSD symptoms (COVID-19-related vs. COVID-19 unrelated PTSD) and comorbid symptoms (i.e., anxiety, depression) and other measures (i.e., emotion regulation, self-injury, anger). Individuals diagnosed with PTSD were randomly assigned to the UP-A (n = 46) or TF-CBT group (n = 47), administered the SCID-5 and a battery of measures and followed up posttreatment and then after 3, 6, and 9 months. Ninety-three adolescents with PTSD were enrolled, 45% boys and 61% COVID-19-related PTSD. We adopted an intention-to-treat approach. At the initial post-intervention assessment, except for emotion regulation and unexpressed angry feelings, in which UP-A participants reported greater reductions, no significant differences in other variables were secured between the UP-A and TF-CBT. However, at follow-up assessments, the UP-A evidenced significantly better outcomes than TF-CBT. We found support for the UP-A compared with TF-CBT in treating adolescents with PTSD, regardless of COVID-19-related PTSD status, in maintaining treatment effectiveness over time.

Mindfulness and COVID-19-Related Stress: Staying Present During Uncertain Times.

Objectives: The SARS-CoV-2 (COVID-19) pandemic is recognized as a mass traumatic event in which COVID-19-related stress (CS) can indicate other trauma- and/or stressor-related disorder. The facets of mindfulness (observing, describing, acting with awareness, nonjudging, and nonreacting) have been linked to reductions in stress-related symptoms and thus may protect against CS. We extended previous research by evaluating mindfulness facets as resilience skills negatively related to CS. Method: Undergraduate students (n = 495) completed an online battery of questionnaires. A subsample of students endorsing clinically elevated CS (n = 165) was also evaluated. We utilized hierarchical regression to account statistically for the mindfulness facets in addition to indicators of psychological distress (e.g., negative affect, neuroticism, dissociation) and social desirability. We performed analyses twice, once in the overall sample, and once in the high CS subsample. Results: Less observing and greater nonjudging related to reduced CS while other study variables were controlled for in the overall sample. In contrast, acting with awareness and nonjudging negatively related to CS in the subsample, but were not related to CS when we accounted for psychological-distress variables that positively related to CS in the analysis. Conclusions: Although variables indicative of psychological distress robustly contribute to CS, observing, acting with awareness, and nonjudging may be mindfulness skills that can be targeted to buffer clinically significant CS. Preregistration: This study was not pre-registered.

A novel ego dissolution scale: A construct validation study.

Ego dissolution (i.e., ego loss, ego disintegration, ego death, or self-loss) is a conscious state marked by a loss or diminution of one's sense of self and a lack of first-person experience. We developed a novel, valid, and internally consistent ego dissolution scale to both (a) assess trait-like aspects of ego dissolution, which have received scant attention to date, and (b) facilitate future research in a variety of contexts (e.g., personality, psychopathology, substance use/psychedelics, contemplative practices). We determined that the 10-item Ego Dissolution Scale (EDS; Cronbach's α = 0.80) and its identified subfactors of Ego-Loss (Cronbach's α = 0.84) and Unity (Cronbach's α = 0.75) were internally consistent, possessed strong convergent (e.g., depersonalization/derealization, mysticism, unusual experiences) and discriminant validity (e.g., neuroticism, social desirability). We found ego dissolution and dissociation to be empirically related yet discriminable on a statistical basis.

Oversimplifications and Misrepresentations in the Repressed Memory Debate: A Reply to Ross.

Ross argued that false memory researchers misunderstand the concepts of repression and dissociation, as well as the writings of Freud. In this commentary, we show that Ross is wrong. He oversimplifies and misrepresents the literature on repressed and false memory. We rebut Ross by showing the fallacies underlying his arguments. For example, we adduce evidence showing that the notions of dissociation or repression are unnecessary to explain how people may forget and then remember childhood sexual abuse, stressing that abuse survivors may reinterpret childhood events later in life. Also, Ross overlooks previous critiques concerning dissociation. Finally, we will demonstrate that Ross misrepresents work by Freud and Loftus in the area of repressed and false memory. His article confuses, not clarifies, an already heated debate on the existence of repressed memory.

The response set theory of hypnosis reconsidered: toward an integrative model.

Irving Kirsch is a leading figure in the field of psychological science who has advanced our understanding of hypnosis in key respects that have withstood the tests of time and replication. We honor his prodigious contributions over his distinguished career and extend his response expectancy theory in an integrative model that encompasses predictive coding. We review the construct of expectancies that he articulated and championed for decades and extended in response set theory. We propose novel hypotheses to align his innovative contributions with the most current findings in psychological science and to acknowledge the heuristic value of his work. We especially focus on (I) how the response set theory can be conceptualized in terms of the predictive coding model and (II) psycho-social constructs that need to be considered to better understand the effects of expectancies on hypnotic phenomena in an open and evidence-based integrative model of hypnosis.

Dissociation and Dissociative Disorders Reconsidered: Beyond Sociocognitive and Trauma Models Toward a Transtheoretical Framework.

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 identifyempirical pathways for future research to advance our understanding of dissociation, including studies of highly adverse events and dissociation.

Quality of life, emotion regulation, and dissociation: Evaluating unique relations in an undergraduate sample and probable PTSD subsample.

OBJECTIVE: Previous research has documented a strong association between emotion regulation (ER) and quality of life (QoL). Nevertheless, extant studies have not tested this association in participants meeting diagnostic criteria for posttraumatic stress disorder nor accounted for other explanatory variables statistically. Our primary objective was to evaluate the unique relations among ER dimensions and QoL while controlling for dissociation, neuroticism, and PTSD symptoms statistically. Our secondary aim was to test the hypothesis that the correlation between PTSD symptoms and dissociation will be greater in a sample with clinically elevated PTSD compared with a nonclinical sample. METHOD: Data were collected from an unselected undergraduate sample (N = 502) and a subsample of participants with probable PTSD (N = 53) using self-report measures. RESULTS: Analyses revealed that increased general emotional dysregulation, dissociation, PTSD symptoms, blaming others, neuroticism, and impulsivity were uniquely related to poor QoL in the overall sample whereas increased dissociation, impulsivity, and blaming others were uniquely related to poor QoL in the probable PTSD subsample. We found evidence for a moderate correlation between PTSD symptoms and dissociation in the probable PTSD subsample, but this correlation was not significantly greater than the correlation between the two variables in the overall sample. CONCLUSIONS: ER dimensions (e.g., dissociation, blaming others, impulsivity) may represent novel treatment targets for tailored psychosocial interventions promoting QoL in the general population and individuals with PTSD. Future longitudinal studies with a larger trauma-exposed sample are necessary to replicate and extend our findings. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Belief in Unconscious Repressed Memory Persists.

On the basis of converging research, we concluded that the controversial topic of unconscious blockage of psychological trauma (i.e., repressed memory) remains very much alive in clinical, legal, and academic contexts. In his commentary, Brewin (this issue, p. 443) conducted a cocitation analysis and concluded that scholars do not adhere to the concept of unconscious repression. Furthermore, he argued that previous survey research did not specifically assess unconscious repression. Here, we present critical evidence that runs counter to his claims. First, we inspected his cocitation analysis and found that some scholars support notions that are closely related to unconscious repression. Furthermore, we conducted another analysis on the basis of articles' similarity. Again, we found examples of scholars specifically endorsing unconscious repressed memories. Second, as opposed to what Brewin reports, recent survey research now exists that bears directly on people's beliefs regarding unconscious repression. This work reveals that large percentages of people (e.g., students and eye-movement desensitization and reprocessing [EMDR] clinicians) endorse the concept of unconscious repressed memories. The belief in unconscious repressed memory can continue to contribute to harmful consequences in clinical, legal, and academic domains (e.g., false accusations of abuse).

Belief in unconscious repressed memory is widespread: A comment on Brewin, Li, Ntarantana, Unsworth, and McNeilis (2019).

What does believing in repressed memory mean? In a recent article in this journal, Brewin, Li, Ntarantana, Unsworth, and McNeilis (2019, Study 3) argued that when people are asked to indicate their belief in repressed memory, they might actually think of deliberate memory suppression rather than unconscious repressed memory. They further argued that in contrast to belief in unconscious repressed memory, belief in deliberate memory suppression is not scientifically controversial. In this commentary, we show that they are incorrect on both counts. Although Brewin and colleagues surveyed people to indicate their belief in deliberate memory suppression, they neglected to ask their participants whether they (also) believed in unconscious repressed memory. We asked people from the general population whether they believed that traumatic experiences can be unconsciously repressed for many years and then recovered. In 2 studies of the general population, we found high endorsement rates (Study 1 [N = 230]: 59.2% [n = 45]; Study 2 [N = 79]: 67.1% [n = 53]) of the belief in unconscious repressed memory. These endorsement rates did not statistically differ from endorsement rates to statements on repressed memory and deliberate memory suppression. In contrast to what Brewin et al. argued, belief in unconscious repressed memory among lay people is alive and well. Finally, we contend that Brewin et al. overstated the scientific evidence bearing on deliberate repression (suppression). (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Skirting the issue: What does believing in repression mean?

We show that, in contrast to Brewin, Li, Ntarantana, Unsowrth, and McNeilis (2019), large proportions of laypersons believe in the scientifically controversial phenomenon of unconscious repressed memories. We provide new survey data showing that when participants are asked specific questions about what they mean when they report that traumatic memories can be repressed, most provide answers strongly consistent with unconscious repression. Our findings continue to show that researchers, legal professionals, and clinicians should be wary of invoking unconscious repression in their work.

Stress and Coping in the Time of Covid-19: Pathways to Resilience and Recovery.

Coronavirus Disease 2019 (COVID-19) has disrupted virtually every aspect of daily living, engendering forced isolation and social distance, economic hardship, fears of contracting a potentially lethal illness and feelings of helplessness and hopelessness. Unfortunately, there is no formula or operating manual for how to cope with the current global pandemic. Previous research has documented an array of responses to mass crises or disasters, including chronic anxiety and posttraumatic stress as well as resilience and recovery. Much can be learned from this research about how people have coped in the past in order to identify strategies that may be particularly effective in managing distress and cultivating resilience during these perilous times. We delineate multiple coping strategies (e.g., behavioral activation, acceptance-based coping, mindfulness practice, loving-kindness practices) geared to decrease stress and promote resilience and recovery. These strategies may be especially effective because they help individuals make meaning, build distress tolerance, increase social support, foster a view of our deep human interconnectedness, and take goal-directed value-driven actions in midst of the COVID-19 pandemic.

The Return of the Repressed: The Persistent and Problematic Claims of Long-Forgotten Trauma.

Can purely psychological trauma lead to a complete blockage of autobiographical memories? This long-standing question about the existence of repressed memories has been at the heart of one of the most heated debates in modern psychology. These so-called memory wars originated in the 1990s, and many scholars have assumed that they are over. We demonstrate that this assumption is incorrect and that the controversial issue of repressed memories is alive and well and may even be on the rise. We review converging research and data from legal cases indicating that the topic of repressed memories remains active in clinical, legal, and academic settings. We show that the belief in repressed memories occurs on a nontrivial scale (58%) and appears to have increased among clinical psychologists since the 1990s. We also demonstrate that the scientifically controversial concept of dissociative amnesia, which we argue is a substitute term for memory repression, has gained in popularity. Finally, we review work on the adverse side effects of certain psychotherapeutic techniques, some of which may be linked to the recovery of repressed memories. The memory wars have not vanished. They have continued to endure and contribute to potentially damaging consequences in clinical, legal, and academic contexts.

HYPNOSIS, HYPNOTIC PHENOMENA, AND HYPNOTIC RESPONSIVENESS: Clinical and Research Foundations-A 40-Year Perspective.

The authors summarize research findings, their clinical implications, and directions for future research derived from 40 years of study of hypnosis, hypnotic phenomena, and hypnotic responsiveness at Steven Jay Lynn's Laboratory of Consciousness, Cognition, and Psychopathology and Joseph P. Green's Laboratory of Hypnosis. We discuss (a) the accumulating body of evidence that hypnosis can be used to advantage in psychotherapy; (b) the fact that hypnosis can facilitate a broad array of subjective experiences and suggestions; (c) the failure to find a reliable marker of a trance or radically altered state of consciousness and reservations about conceptualizing hypnosis in such terms; (d) determinants of hypnotic responsiveness, including attitudes and beliefs, personality traits, expectancies, motivation, and rapport; (e) efforts to modify hypnotic suggestibility; and (f) the need to further examine attentional abilities and the role of adopting a readiness response set that the authors argue is key in maximizing hypnotic responsiveness.

Dissociation and its disorders: Competing models, future directions, and a way forward.

Dissociative experiences and symptoms have sparked intense scrutiny and debate for more than a century. Two perspectives, the trauma model (TM), which postulates a direct and potent causal link between trauma and dissociation, and the sociocognitive model (SCM), which emphasizes social and cognitive variables (e.g., fantasy-proneness, media influences, suggestibility, suggestion, cognitive failures), currently vie for support. The intensive focus on controversies has stymied progress in understanding dissociation as much, if not more, than it has inspired research that transcends a single perspective. We assess strengths and limitations of these two perspectives and contend that neither provides a complete account of dissociation symptoms, which occur in the presence of many disorders. We provide a novel, narrative review of the link between dissociation and dissociative disorders and sleep disruptions, hyperassociativity, set shifts, deficits in meta-consciousness, and impaired self-regulation. We suggest that these transtheoretical variables (a) play a role in disorders that covary extensively with dissociative disorders (i.e., borderline personality disorder, schizophrenia spectrum disorders) and (b) provide the basis for overlapping foci of interests and potential collaborations among proponents of competing theoretical camps. Finally, we discuss limitations in knowledge and unresolved issues for future workers in the field to pursue.
