This study consolidated the association of mindfulness with perceived stress found across studies. A meta-analysis examined the relationship between mindfulness and perceived stress in 56 samples, which included a total of 24,494 participants. The weighted effect size of r(55) = -0.40, 95% CI [-0.36, 0-44], p = 0.0001, showed that greater mindfulness was associated with less perceived stress....
Although ubiquitous in numerous nightlife cultures, poker-machines present a high risk for problematic use and addiction. Previous research has demonstrated that gambling cues (e.g., flashing lights) can activate gambling urges in poker-machine gamblers. However, the processes that contribute to the maintenance of cue-reactive urges to gamble remain unclear. Consequently, the present study...
This participatory team science project extended Laythe and Houran’s (2022) prior application of a famous probabilistic argument known as the "Drake equation" to the question of postmortem survival. Specifically, we evaluated effect sizes from peer-reviewed, empirical studies to determine the maximum average percentage effect that ostensibly supports (i.e., "anomalous effects") or refutes...
We used a multiteam system approach (MTS) to map the critical and constructive feedback from four invited Commentaries on Rock et al.’s (2023) probabilistic analysis of purported evidence for postmortem survival. The goal was to mine actionable insights to guide future research with the potential for important learnings or breakthroughs about the nature or limits of human consciousness and...

Spiritual emergency (SEY) refers to a process of spiritual emergence (SE) or awakening that becomes traumatic for an individual, leading to a state of psychological crisis. There is evidence that SE(Y) is associated with both psychotic symptomatology and personality traits. This study examined the relationship between SE(Y), psychotic symptoms, and schizotypy, a construct that addresses...
Although phenomenologist Edmund Husserl’s project was not directed at transpersonal experiences, his methods are nevertheless applicable in a profound and effective way. We explore Husserl’s project and its methods for their relevance to transpersonal studies. Husserl laid out the proposition that science, including psychology, must be grounded in the study of perception, which after all is the...
This essay provides an anthropological account of a neuroepistemological account of mystical experience. We commence by outlining the various qualities of mystical experience (e.g. time-consciousness and space-consciousness distortion). Subsequently, we analyse the epistemology of mystical experience with special reference to the constructivist versus decontextualist debate. Next, we formulate...
Dream-ESP is a form of extra-sensory perception (ESP) in which a dreaming perceiver ostensibly gains information about a randomly selected target without using the normal sensory modalities or logical inference. We conducted a meta-analysis on dream-ESP studies (dating from 1966 to 2016), and found a number of significant effects indicating support for the ESP hypothesis (Storm et al., 2017)....
In order to further our understanding about the limits of human consciousness and the dream state, we report meta-analytic results on experimental dream-ESP studies for the period 1966 to 2016. Dream-ESP can be defined as a form of extra-sensory perception (ESP) in which a dreaming perceiver ostensibly gains information about a randomly selected target without using the normal sensory...
Shamanism is a worldwide social phenomenon consisting of a set of practices (e.g., ritualistic drumming, sensory deprivation, the ingestion of entheogens and dream incubation) designed to obtain knowledge from alternative realities for the purpose of benefiting one's social group. The aim of this paper is to provide a cross-cultural exploration of dreaming in the context of shamanism. We...
In metaphysics there exist long-standing, unresolved problems regarding causation. Indeed, rationalist and empiricist philosophers remain engaged in an intricate debate concerning the ontology of causal relations. We review rationalist and empiricist approaches to the problem of causality and formulate transpersonally orientated criticisms of each. Subsequently, we apply Tart’s notion of a...
Previous studies have linked shamanic practices to high levels of altered personal meaning and reductions in mood disturbance. However, these studies have neglected to investigate whether the effect of shamanic stimulus conditions on mood disturbance is moderated by altered meaning. Moreover, previous research has not evaluated whether, during shamanic journeying, there exists an indirect...
Previous research concerning the relationship between the shaman’s conscious experiences and the ‘spirit world’ suggests that shamans are realists in the sense that they conceptualize their multi-layered universe (e.g., upper, middle and lower world) as real, objective and independent of the perceiver. However, these studies have neglected to analyze the logical coherence of a realist...
ABSTRACT The subjective effects and therapeutic potential of the shamanic practice of journeying is well known. However, previous research has neglected to provide a comprehensive assessment of the subjective effects of shamanic‐like journeying techniques on non‐shamans. Shamanic‐like techniques are those that demonstrate some similarity to shamanic practices and yet deviate from what may...
Attempts to elucidate the kinds of "thing" or "things" to which the term shamanic journeying image is referentially linked must grapple with two related questions: what is the fundamental nature of shamanic journeying images, and how might the origin of a shamanic journeying image be found? The first question is ontological, concerned with the nature and essence of shamanic journeying images....
Block (2002) has argued that the multiplicity of meanings ascribed to consciousness is due\nto the erroneous treatment of very different concepts as a single concept. Block distinguished\nfour notions of consciousness intended to encapsulate the various meanings attributed to\nthe term: phenomenal, access, self, and monitoring consciousness. We argue that what is\ncommon to all of these...
This study develops the methodological framework advanced in Rock, Baynes, and Casey's (2005) experimental study of ostensibly shamanic journeying imagery in naïve participants. Specifically, the present study experimentally investigates the impact of the word landscape, featured in Harner's (1990) shamanic journeying to the Lower World instructions, on the number of landscape‐related images...
This study explored ostensibly shamanic journeying imagery by (a) assessing visual images across induction techniques (i.e., sonic driving, Ganzfeld, relaxation, and sitting with eyes open); (b) determining combination( s) of induction technique and instructions most associated with religious imagery; and (c) investigating the origins of visual imagery. Six participants were randomly assigned...
