Abstract: In our article (Storm, Tressoldi, & Di Risio, 2010), we claimed that the ganzfeld experimental design has proved to be consistent and reliable. However, Hyman (2010) argues that the overall evidence for psi is, in fact, contradictory and elusive. We present a case for psi research that undermines Hyman's argument. First, we give ex les from parapsychologists who do not outrightly dismiss psi, despite appearances, but actually support it. Second, we claim that Hyman does not tell the full story about the ganzfeld meta-analytic findings and thus presents a one-sided account. Third, we argue that our meta-analysis has followed standard procedures, that we have not broken any rules but have found a communications anomaly, often referred to as psi. Though we may be in agreement that the evidence is largely statistical, the evidence suggests that concealed targets are actually identified rather than guessed. We argue that further research is necessary.

Abstract: J. Milton and R. Wiseman (1999) attempted to replicate D. Bem and C. Honorton's (1994) meta-analysis, which yielded evidence that the ganzfeld is a suitable method for demonstrating anomalous communication. Using a database of 30 ganzfeld and autoganzfeld studies, Milton and Wiseman's meta-analysis yielded an effect size (ES) of only 0.013 (Stouffer Z = 0.70, p = .24, one-tailed). Thus they failed to replicate Bem and Honorton's finding (ES = 0.162, Stouffer Z = 2.52, p = 5.90 x 10(-3), one-tailed). The authors conducted stepwise performance comparisons between all available databases of ganzfeld research, which were argued not to be lacking in quality. Larger aggregates of such studies were formed, including a database comprising 79 ganzfeld-autoganzfeld studies (ES = 0.138, Stouffer Z = 5.66, p = 7.78 x 10(-9)). Thus Bem and Honorton's positive conclusion was confirmed. More accurate population parameters for the ganzfeld and autoganzfeld domains were calculated. Significant bidirectional psi effects were also found in all databases. The ganzfeld appears to be a replicable technique for producing psi effects in the laboratory.

Abstract: Previous research has demonstrated the effects of ostensible subtle energy on physical systems and subjective experience. However, one subtle energy technique that has been neglected, despite anecdotal support for its efficacy, is Quantum BioEnergetics (QBE). Furthermore, the influence of paranormal belief and experience (either real belief/experience or suggested belief/experience) on subtle energy effects remains unclear. The aim of the present study was to investigate experimentally the effects of distant QBE healing, and paranormal belief/experience, on mood. A randomized expectancy-enhanced placebo-controlled design was used. Data were collected at the QBE Centre, Melbourne. Participants were students from Deakin University and from the general public. Snowball s ling (ie, word-of-mouth) and convenience s ling using a ballot box placed in the university library. Profile of Mood States-Short Form was used to quantify positive and negative mood states. The QBE condition was associated with (1) significantly less Tension-Anxiety compared with the placebo and control condition and (2) significantly less Anger-Hostility and Total Mood Disturbance compared with the control condition (but not the placebo condition). Furthermore, there was an interaction of condition and paranormal belief/experience with regard to Depression-Dejection, with believers assigned to the placebo condition scoring lowest on this Mood variable. Findings suggest that the use of QBE by an experienced practitioner reduces mood disturbance. In addition, the placebo condition may have evoked suggestibility effects in believers, which would mean that they may be more likely than nonbelievers to believe that they were receiving healing, thus resulting in lower Depression-Dejection scores.

Abstract: We report the results of meta-analyses on 3 types of free-response study: (a) ganzfeld (a technique that enhances a communication anomaly referred to as "psi") (b) nonganzfeld noise reduction using alleged psi-enhancing techniques such as dream psi, meditation, relaxation, or hypnosis and (c) standard free response (nonganzfeld, no noise reduction). For the period 1997-2008, a homogeneous data set of 29 ganzfeld studies yielded a mean effect size of 0.142 (Stouffer Z = 5.48, p = 2.13 x 10(-8)). A homogeneous nonganzfeld noise reduction data set of 16 studies yielded a mean effect size of 0.110 (Stouffer Z = 3.35, p = 2.08 x 10(-4)), and a homogeneous data set of 14 standard free-response studies produced a weak negative mean effect size of -0.029 (Stouffer Z = -2.29, p = .989). The mean effect size value of the ganzfeld database was significantly higher than the mean effect size of the standard free-response database but was not higher than the effect size of the nonganzfeld noise reduction database [corrected].We also found that selected participants (believers in the paranormal, meditators, etc.) had a performance advantage over unselected participants, but only if they were in the ganzfeld condition.

Abstract: A quantitative observational study was undertaken to examine the relationship between in idual factors and level of gambling involvement, in particular problem gambling (PG). The specific factors under study were personality, perceived luck, and attitudes towards gambling. A s le of university students (N = 185) completed a battery of questionnaires, consisting of the 16PF, Canadian Problem Gambling Index, Belief in Good Luck Scale (BIGL), Gambling Attitudes Scale (GAS), and the Impulsive Non-Conformity subscale (ImpNon) from the Oxford-Liverpool Inventory of Feelings and Experiences. Four groups were formed (Non-PG, Low-Risk, Moderate-Risk, and PG). Personality profiles varied between groups, and there were significant main effects and interaction effects on gender and personality factors. The PG group was higher on impulsivity, and belief in luck, and had more positive attitudes towards gambling. Multiple Regression Analysis and Discriminant Functions Analysis, using variables including some 16PF factors, BIGL and GAS variables, produced models that were highly predictive of gambling severity and gambling membership. In both models, impulsivity was the strongest predictor. These results were discussed in terms of their implications for future research and treatment of PG.

Abstract: C.G. Jung proposed that archetypal symbols carry implicit meanings. We therefore hypothesised that symbol cueing facilitates memory and subsequent recall of meaning words associated with symbols. In the present study, participants either freely generated, or selected from a list, one meaning word for each of 30 symbols presented on screen. As expected, results showed little evidence of conscious knowledge of meaning words. Upon presentation of two sets of symbols and meaning words (15 pairs matched 15 pairs mismatched), words from the matched-pairs set were correctly recalled significantly more often than words from the mismatched-pairs set. Our findings were considered from a cognitive and clinical perspective.

Abstract: Objective: The aim of this study was to assess the results of all meta-analyses on anomalous cognition conducted between 1989 and 2021 in order to find moderators associated with greater effect sizes. Method: We included all meta-analyses of studies related to anomalous cognition published up to 2021.Results: Our dataset, accumulated over more than 80 years of investigation, refers to 11 meta-analyses related to six different states of consciousness. The evidence clearly shows that anomalous cognition seems possible and its effects can be enhanced by using a combination of some non-ordinary or altered states of consciousness (e.g., dreaming, ganzfeld, etc.), coupled with free-response procedures, or neurophysiological dependent variables. These conditions facilitate an alternative form of cognition seemingly unconstrained by the known biological characteristics of the sense organs and the brain. Conclusion: The accumulated evidence expands our understanding of the mind-brain relation and the nature of the human mind.

Abstract: We report the results of an update to the meta-analysis by Storm, Tressoldi, and Di Risio (2010). Three laboratory-based free-response designs were assessed: (i) ganzfeld (a technique proposed to enhance a communication anomaly referred to as extra-sensory perception ESP) (ii) nonganzfeld noise reduction using alleged ESP-enhancing techniques (e.g., dreaming, hypnosis, relaxation, and meditation) and (iii) standard free-response (nonganzfeld non-noise-reduction). For the period 2009 to 2018, a dataset of nine new ganzfeld studies (Category 1) yielded a mean effect size (ES) of 0.119 (where ES = z/√n) 19 new nonganzfeld noise-reduction studies (Category 2) yielded mean ES = 0.045 and 15 new standard free-response studies (Category 3) yielded mean ES = 0.050. Stouffer Z scores for all three databases were significant, but each new database was not significantly different from its respective database in Storm et al. (2010). The increased ganzfeld database (N = 38) yielded a mean ES = 0.133 the nonganzfeld noise-reduction database (N = 37) yielded mean ES = 0.072 and the standard free-response database (N = 33) yielded mean ES = 0.027. Again, Stouffer Z scores were significant. We found Category 1 had a significantly higher mean effect than Category 3, and participants who were selected for the studies (they believed in psi, or practiced, say, meditation, etc.) produced a stronger mean effect than unselected (randomly assigned) participants, but there were no differences between type of modality tested (i.e., telepathy, clairvoyance, precognition), types of target (film clips, photographs, etc.), or experimenter/laboratory. There was also no evidence of a decline effect across a 44-year period. Finally, we conducted a Bayesian analysis and found that the case for a communication anomaly using free-response designs was upheld.

Abstract: Rouder, Morey, and Province (2013) stated that (a) the evidence-based case for psi in Storm, Tressoldi, and Di Risio's (2010) meta-analysis is supported only by a number of studies that used manual randomization, and (b) when these studies are excluded so that only investigations using automatic randomization are evaluated (and some additional studies previously omitted by Storm et al., 2010, are included), the evidence for psi is "unpersuasive." Rouder et al. used a Bayesian approach, and we adopted the same methodology, finding that our case is upheld. Because of recent updates and corrections, we reassessed the free-response databases of Storm et al. using a frequentist approach. We discuss and critique the assumptions and findings of Rouder et al.
