“…This finding is consistent with other studies that have reported an association between absorption, hallucinatory experiences and ASEs (Glicksohn & Barrett, 2003; Humpston et al, 2016; Perona-Garcelan et al, 2012). …”

“…Importantly, however, some bipolar and non-clinical participants were also categorized as members of this cluster, suggesting that absorption may be an important dimension of psychosis (or psychotic like experiences) understood not as a categorical construct but a dimensional population level continuum. This finding aligns with prior research finding elevated absorption scores among healthy adults with psychotic-like experiences (Humpston et al, 2016). …”

“…Humpston et al, (2016) found that both absorption and “detachment-type” dissociation versus “compartmentalization-type” dissociation significantly predicted psychotic-like experiences in a non-clinical population. Similarly, absorption and depersonalization (which is a type of detachment-type dissociation) have been found to predict hallucination proneness in healthy subjects (Perona-Garcelán et al, 2013).…”

“…Empirically, absorption also correlates with hypnotizeability, proneness to spiritual experiences, included altered meditative or dissociative states, and the intensity of response to LSD and other psychedelics (Tellegen & Atkinson, 1974; Luhrmann, Nusbaum, & Thisted, 2010; Humpston et al, 2016; Tagliazucchi, Carhart-Harris, Leech, Nutt, & Chialvo, 2014). In contrast, patients with schizophrenia have shown diminished hypnotizeability relative to patients with dissociative disorders on at least some dimensions (Frischholz et al, 1992).…”

Understanding alterations in perceptual experiences as a component of the basic symptom structure of psychosis may improve early detection and the identification of subtle shifts that can precede symptom exacerbation. We explored the phenomenological construct of absorption and psychotic experiences in both clinical (bipolar psychosis and schizophrenia spectrum) and non-clinical participants. Participants with psychosis endorsed significantly higher absorption compared to the non-clinical group. Absorption was positively correlated with all types of hallucinations and multiple types of delusions. The analysis yielded two distinct cluster groups that demarcated a distinction along the continuum of self-disturbance: on characterized by attenuated ego boundaries and the other stable ego boundaries. The study suggests that absorption is a potentially important but under-researched component of psychosis that overlaps with, but is not identical to the more heavily theorized constructs of aberrant salience and hyperreflexivity.

“…In line with these longitudinal observations, experimental evidence suggests that sleep deprivation has a causal effect on PLEs. For instance, Giesbrecht and colleagues showed that one night of sleep deprivation increased dissociative experiences that share many features with PLEs . Further studies have shown that total sleep deprivation induced PLEs , but the mediating role of negative affect following experimental sleep deprivation remains to be clarified.…”

Simor P, B athori N, Nagy T, Polner B. Poor sleep quality predicts psychotic-like symptoms: an experience sampling study in young adults with schizotypal traits Objective: Psychotic-like experiences (PLEs) are unusual experiences such as perceptual abnormalities and delusional-like thoughts that resemble the symptoms of psychosis at the sub-clinical level. PLEs are associated with sleep complaints in healthy and clinical samples; however, evidence for day-to-day associations between poor sleep and subsequent PLEs under naturalistic conditions is scarce. We hypothesized that poor sleep quality would predict next days' PLEs, and vice versa, daytime PLEs would be associated with worse subsequent sleep quality. Method: Seventy-three university students with moderate to high levels of positive schizotypy participated in an experience sampling study. Participants rated their sleep each morning, as well as PLEs and affective states during the day over 3 weeks. Results: Multilevel regression models indicated that poor sleep quality predicted increased PLEs the following day. Poor sleep was linked to negative daytime mood that partially mediated the associations between sleep quality and next days' PLEs. Furthermore, PLEs were enhanced in the evening as compared to daytime reports. The prediction of poor sleep quality by previous days' PLEs was negligible. Conclusions: The results are consistent with the position that sleeprelated interventions might reduce the risk of psychosis, especially in individuals that tend to experience psychotic-like phenomena and negative affect.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited. Significant Outcomes• Poor subjective sleep quality and short sleep predicted next days' psychotic-like experiences.• More psychotic-like experiences during the day predicted lower sleep quality the following night to some extent, but explained only a negligible portion of the variance.• The temporal associations between sleep quality and psychotic-like experiences were partially mediated by negative mood. Limitations• Sleep quality was measured by self-report questionnaires.• Lack of objective measures (e.g., actigraphy) of sleep quality. • High ratio of female participants.
