N,N-dimethyltryptamine (DMT) is an endogenous hallucinogenic compound in the same chemical class as the more common psilocybin and the neurotransmitter serotonin. Despite previous experimental research assessing the subjective effects of DMT (e.g., Strassman et al., 1994), no qualitative studies have been conducted. Consequently, 19 DMT users were asked to provide thorough descriptions of the subjective effects of DMT via an online survey. A thematic analysis using various principles of phenomenological methodology elicited nine comprehensive constituent themes that ostensibly captured the essential (...) aspects of the DMT-induced state. Keywords: N,N-dimethyltryptamine—phenomenology—thematic analysis. (shrink)

The concept of transformative experience (TE) has been widely explored by several disciplines from philosophy to neurobiology, and in different domains, from the spiritual to the educational one. This attitude has engendered heterogeneous models to explain this phenomenon. However, a consistent and clear understanding of this construct remains elusive. The aim of this work is to provide an initial comprehensive interdisciplinary, cross-domain, up-to-date, and integrated overview on the concept of TEs. Firstly, all the models and theories on TEs were reviewed (...) to extract and analyze TEs’ main components emerging from different disciplines. Then, this preliminary analysis was integrated with an in-depth examination of redundancies and particularities across domains and disciplines, to provide an integrated theoretical framework of TEs and a preliminary interdisciplinary operational definition of TEs. This examination, in turn, can help organize current research and theories, thus providing suggestions for operationalizing TEs as well as encouraging new interdisciplinary research endeavors.

The cognitive and evolutionary sciences of religion offer a standard model of religious representations, but no equivalent paradigm for investigating religiously interpreted altered states of consciousness (religious ASCs). Here, I describe a neo‐Durkheimian framework for studying religious ASCs that centralizes social predictive cognition. Within a processual model of ritual, ritual behaviors toggle between reinforcing normative social structures and downplaying them. Specifically, antistructural ritual shifts cognitive focus away from conventional affordances, collective intentionality, and social prediction, and toward physical affordances and behavioral (...) motivations that make few references to others’ intentional states. Using synchrony and dance as paradigmatic examples of antistructural ritual that stimulate religious ASCs, I assemble literature from anthropology, cognitive neuroscience, and philosophy of language to offer fruitful empirical predictions and opportunities for testing based on this framework. Among the empirical predictions is that antistructural ritual may provide for cultural change in religions when religions are construed as complex adaptive systems. (shrink)
