Sixty participants observed either repeated SOC sequences or random sequences during RSVP, then completed explicit learning tasks and an SRTT. Explicit learning tasks showed no evidence of sequence knowledge. In the SRTT, groups did not differ in RTs, but the control group accumulated more errors in later blocks. Furthermore, RTs during the first two blocks predicted performance in recovery after interference in later blocks in the experimental group. This RT pattern was also reflected in the speed–accuracy trade-off as captured by inverse efficiency scores (IES) but only partially by the balanced integration scores (BIS). Finally, in the SRTT the experimental group reported higher awareness of sequence repetitiveness.

Meditation typically produces gradual improvements through sustained practice, whereas psychedelics may induce acute shifts. To examine these dynamics, we re-analysed data from two cross-sectional online surveys using multiple regression models. In Study 1 (N = 679), we assessed associations of cumulative psychedelic use and meditation practice with well-being, ill-being, and psychological flexibility. When examined separately, both practices were associated with greater well-being and flexibility. However, when considered jointly, the associations for psychedelics were reduced or became nonsignificant, whereas meditation remained consistently associated with the outcomes. Weak evidence also emerged for a potential synergy effect via an interaction between the two practices. In Study 2 (N = 137), we examined perceived well-being changes following a personally meaningful experience facilitated by psychedelics alone, meditation alone, or both combined. Participants in the combined and meditation groups reported significantly greater improvements compared with the psychedelic-only group, although all groups showed positive change on average. Together, these findings suggest that meditation may enhance the benefits of psychedelic experiences and that meditation practice can confound associations between psychedelic use and well-being. More broadly, they highlight the importance of considering both practices together when evaluating their contributions to mental health outcomes.</div></div>","PeriodicalId":51358,"journal":{"name":"Consciousness and Cognition","volume":"137 ","pages":"Article 103977"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145769951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study elaborates on this finding by comparing reports of rotated letters to two kinds of controls: letters shown upright, and letters that were not shown in the preceding stimulus. Results showed that participants were able to discriminate non-cued letters from not-shown letters, providing evidence that such letters remained available for some time after stimulus offset. This was found for letters that were shown upright but also for letters shown inverted. Upright letters were reported as upright more often than not-shown letters were, showing that information about letter orientation was preserved. Inverted letters were also reported as upright but, importantly, not more so than not-shown letters were. This replicates the earlier finding that inverted letters can be reported as upright but shows that such errors might be attributable to non-perceptual stages of processing.

Involuntary mental imagery (IMI), the spontaneous occurrence of visual or auditory mental content, shares several features with HAs. The continuum hypothesis suggests that these phenomena exist on a spectrum ranging from benign to clinically significant experiences. However, the precise boundaries of these phenomena remain under-explored. This pre-registered cross-sectional study focusing on the experiential continuum, involved 1,951 French-speaking adults who completed an online questionnaire assessing the frequency and characteristics of their HAs and IMI experiences. These experiences could include hearing music or voices, or seeing shadows. Participants rated ten phenomenologically-informed dimensions, including vividness, emotional valence, controllability, distress, agency, and perceived location. Associations were tested using Spearman correlations and Wilcoxon tests with Bonferroni correction. IMIs were significantly more frequent than HAs and were rated as more vivid, emotionally positive, and self-generated. In contrast, HAs were associated with greater distress and external attribution. Moderate to strong correlations between HAs and IMIs on most dimensions support the hypothesis of a shared experiential continuum. However, the fact that confidence and agency cannot be fully separated from controllability raises questions about cognitive models of self-monitoring and metacognition. These findings provide empirical evidence for both convergence and divergence in the phenomenological profiles of HAs and IMIs. Refining these distinctions could enhance theoretical models of hallucinatory experiences and facilitate the early identification and prevention of distressing internal phenomena in individuals at risk.</div></div>","PeriodicalId":51358,"journal":{"name":"Consciousness and Cognition","volume":"137 ","pages":"Article 103974"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145693549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An influential proposal posits that dreaming and mind wandering exist on a continuum of spontaneous thought, in which dreaming is intensified compared to mind wandering. Yet the precise relationship between dreaming and mind wandering is only beginning to be investigated. Unusual features of dream experience, referred to as bizarreness, are at the heart of theoretical debates about the relationship between dreaming and waking experiences. Traditionally, bizarreness was considered as a distinctive and pervasive feature of dreaming that was absent in waking consciousness, whereas recently, it has been proposed as a dimension along which dreaming is an intensified form of waking mind wandering. Our study is the first to apply an in-depth bizarreness analysis to dreaming and mind wandering reports from the same group of participants within a naturalistic setting. Our results, based on 379 spontaneous reports, suggest that both dreaming and waking mind wandering, have unique bizarreness profiles, involving similarities as well as distinctive differences. Bizarreness is kaleidoscopic in that the comparison between dreaming and mind wandering changes with the precise rating and level of measure (bizarreness type, subtypes, contents) used. This means that dreams cannot, straightforwardly, be described as intensified compared to waking mind wandering on measures of bizarreness, and a more nuanced account, alongside more specific measures, is needed. We propose that our findings can inform and guide future work not just on bizarreness in dreams and mind wandering, but also more broadly on the relationship between conscious experiences in sleep and wakefulness.</div></div>","PeriodicalId":51358,"journal":{"name":"Consciousness and Cognition","volume":"137 ","pages":"Article 103965"},"PeriodicalIF":2.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145727175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
