This study is the first to contribute to a registration-based prospective meta-analysis of ganzfeld Extrasensory Perception (ESP) studies. We sought to maximize the anticipated psi effect size by selecting participants for self-reported creativity, prior psi experience or belief, or practice of a mental discipline. We also employed an automated precognition design for simplicity and security, and to add to the small database of precognitive ganzfeld studies. Targets and decoys were short video clips randomly selected with replacement from a pool of 200. As well as predicting overall significant scoring on the ganzfeld precognition task, the study tested the assumption that the ganzfeld method elicits a psi-conducive altered state of consciousness, by correlating two measures of an Altered State of Consciousness (ASC) with precognition task performance. We predicted higher target similarity ratings would be associated with greater evidence of ASC during the session. Three experimenters each conducted 20 trials. Twenty-two direct hits were obtained (37% hit-rate), thus significantly supporting the planned test of the ganzfeld precognition task (exact binomial p = .03, 1-tailed). No relation was found between ASC and psi task performance, contrary to prediction. We conclude by discussing the reasons why further ganzfeld ESP research is justified.

Background: Given the strong tendency for different mental health symptoms to co-occur, there is considerable interest in identifying trans-diagnostic predictors of mental health that can be targets for intervention to efficiently prevent and treat issues across a range of domains. Emotion regulation difficulties have been identified as a correlate of a broad span of mental health issues, making them a key candidate transdiagnostic factor. However, there remains a lack of knowledge about which aspects of emotion regulation – especially as it manifests in the course of daily life – relate to a general risk of mental health issues as opposed to or in addition to specific symptoms.Methods: In the present study, we leverage an ecological momentary assessment (EMA) study design with four measures per day over a two-week period to explore how negative affect levels, inertia, lability, and reactivity to provocation and stress in the course of daily life relate to mental health symptoms in young adults (n= 256, 99 males, 157 females) in the domains of anxiety, depression, psychosis-like symptoms, behaviour problems, suicidality, and substance use. Results: Dynamic structural equation modelling (DSEM) analyses suggested that negative affect levels in daily life were associated with depression, anxiety, indirect aggression, psychosis, anxiety, and self-injury; negative affective lability was associated with anxiety, proactive aggression, reactive aggression, suicidal ideation, ADHD symptoms, and indirect aggression; and negative affective inertia was associated with depression, anxiety, and cannabis use. Conclusions: Findings suggest that emotional lability may be a particularly important aspect of emotion dysregulation to target in transdiagnostic interventions for mental health, with other aspects having more domain-specific associations.

Objective. To use meta-analysis to explore five previously uninvestigated factors related to the sender-receiver dynamic in the telepathy ganzfeld. The five factors of interest are: a) did the receiver see the sender’s room prior to the session?; b) could the sender hear the receiver during the mentation period?; c) could the sender hear the receiver during the judging period?; d) was the sender explicitly told to be silent?; and e) did the experimenter assist in the review section of the session? Method: Telepathy ganzfeld studies conducted post Joint Communiqué, with one session per day and the receivers rating the targets, were chosen. Two mixed-effects models were fit: 1) using the study hit rates as the binomial mean; and 2) using the study hit rates as a proportion. Both models have the five factors as binary moderators. Results: Both the binomial mean and proportion models suggest a significant effect of the moderators overall and two factors individually: 1) the sender being able to hear the receiver during the mentation period; and 2) a review period after the mentation period. Permutation tests for both models also show significant effects of the moderators and the two factors. Conclusion: The sender being able to hear the receiver’s mentation appears to increase overall study success, while the review period decreases overall study success
