Recent research shows that young children frequently report non-ordinary experiences, including extra sensory perceptions, out-of-body experiences, and states of self-transcendence, reflecting relational, pre-linguistic, and weakly individualised forms of consciousness. This paper integrates qualitative studies of children’s experiences with contemporary altered states of consciousness (ASC)...
Immersive virtual environments are increasingly investigated as tools capable of modulating conscious experience, yet the specific contribution of graded immersion to altered states of consciousness (ASC), time perception, and cognition remains unclear. The present study examined how different levels of immersion during videogame play influence subjective experience and post-experience...
The intensity of the psychedelic experience has been shown to be associated with its clinical efficacy. This study aims to investigate the factors that may influence the level of altered consciousness during naturalistic psychedelic use, which serves as a proxy for the intensity of the psychedelic experience. A retrospective online survey was conducted on individuals who reported a psychedelic...
Personally meaningful music can evoke vivid emotions and autobiographical memories, reconnecting listeners with their personal past. Whether the autobiographical salience of music, as distinct from familiarity, modulates its effects on an individual’s state of consciousness has not been systematically tested. We compared autobiographically salient (AS) music with a standardized therapeutic...
Practices involving altered states of consciousness (ASCs) are receiving increasing scientific and public attention, particularly in domains such as psychedelic assisted therapy and mindfulness-based interventions (Lee et al., 2021; Nichols et al., 2017). There is also an increasing interest in a broader range of practices involving altered states, including breathwork, ice-bath immersions,...
Pain Within Altered States of Consciousness challenges conventional assumptions about pain. Rather than treating pain as a simple product of tissue damage, this book presents it as a dynamic construction of conscious experience—shaped by brain networks, attention, emotion, expectation, and the organization of the self. Bringing together anesthesiology, neuroscience, pain medicine, contemplative...
The Five Dimensional Altered States of Consciousness (5D-ASC) Rating Scale is a self-report measure used to characterize changes in consciousness induced by pharmacological (e.g., psychedelics) and non-pharmacological methods (e.g., meditation), and predict clinical outcomes. Although it has been widely used with English-speaking participants, there is no version that has been adapted for...
The intersection of Virtual Reality (VR) and Altered States of Consciousness (ASCs) represents a notable research domain in experimental and clinical contexts, highlighting the growing interest in how immersive technologies can induce, modulate, and assess non-ordinary cognitive and emotional states. This study examines literature from 2014 to 2024, providing a review of the methodological...
Psychedelic substances reliably occasion transient self-transcendent states, including mystical-type experiences, which are theorized to support salutogenic psychological change and long-term well-being. Despite growing interest in these phenomena, little is known about how acute self-transcendent states translate into enduring trait-level changes, or whether individual differences such as...
The Altered States of Consciousness Scale (3/5D-ASC or 11-ASC) is widely used to assess non-ordinary states of consciousness, particularly for psychedelic research. However, its original dimensional model (3D-ASC within 5D-ASC) and later 11-subscale structure (11-ASC) have a hierarchically incompatible higher/lower-order structure. Although the 11-ASC offers superior model fit, the 3D-ASC...
