The Allostatic Reset Model (ARM) of Psychedelic Action

PsyArXiv March 28, 2026 preprint

Despite being induced by a transient pharmacological exposure, psychedelic experiences can catalyze enduring psychological transformation, presenting a central challenge for understanding the mechanism of action of psychedelic medicines. To address this challenge, the Allostatic Reset Model (ARM) of psychedelic action is proposed, which conceptualizes psychedelic therapeutic effects as a...

Consciousness Beyond the Brain: The Role of the Autonomic Nervous System in Non-ordinary States of Consciousness

PsyArXiv March 17, 2026 preprint

Non-ordinary states of consciousness (NOSCs), whether entered via psychedelics, breathwork, hypnosis or other means, show striking therapeutic promise by improving well-being and reducing psychopathology across diverse conditions. While the neuronal dynamics underpinning such therapeutic shifts in consciousness have to some extent been mapped, research has mainly focused on the central nervous...

A Scoping Review and Integrated Model of Embodiment in Psychosis

PsyArXiv March 11, 2026 Ciara Nealon, Brian Patrick Keane, Donagh Seaver O'Leary et al. preprint

AbstractBackground and Hypothesis: Embodiment refers to the integration of sensory, motor, and cognitive processes that underpin self-experience, agency, and bodily awareness. Psychosis studies have demonstrated disruptions in embodied processes through a diverse series of methodological approaches. The aim of this scoping review was to systematically review the range of methodological...

Update of the Altered States Database (ASDB): 2025-12-31

PsyArXiv February 27, 2026 preprint

The Open Data initiative Altered States Database (ASDB) collects psychometric questionnaire data on the subjective experiences of pharmacologically and non-pharmacologically induced altered states of consciousness. The ASDB is updated annually and can be utilized by both researchers and non-scientists to access information or conduct further analyses. The current update adds data published in...

The Eight Dimensions of Altered States of Consciousness in Adults and their Convergence with Childhood Consciousness

PsyArXiv February 8, 2026 preprint

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)...

State Space Theory as a Unifying Framework for Consciousness

PsyArXiv January 24, 2026 preprint

Consciousness science has generated diverse theoretical frameworks, each offering insights into different aspects of conscious experience. However, this diversity has created a fractured landscape: theories operate at different explanatory levels, and a principled account of how conscious phenomena arise from specific neural computations remains largely absent. This work argues that State Space...

Time to drop dualism and its associates: the imaginary magnitude of the hard problem of consciousness

PsyArXiv January 18, 2026 preprint

The field of consciousness research has reached a somewhat contentious atmosphere. From “adversarial collaborations”, where consciousness theories compete, to open letters where researchers label some theories as pseudoscience, the subject is becoming harder to investigate and results difficult to interpret as there is still a significant aura of mysticism rooted in dualism and its modern...

Self-Transcendent Perceptual Dynamics and the Effects of Dispositional Mindfulness on Altered States of Consciousness: A Prospective Longitudinal Observational Study of a Naturalistic Psychedelic Retreat

PsyArXiv December 31, 2025 Sebastian Ehmann, Nikoloz Mosahvili, Angela White et al. preprint

Self-Transcendent Perceptual Dynamics and the Effects of Dispositional Mindfulness on Altered States of Consciousness: A Prospective Longitudinal Observational Study of a Naturalistic Psychedelic Retreat

From Museum to Workshop: A Pragmatist Intervention in Science of Consciousness

PsyArXiv December 12, 2025 preprint

Despite notable empirical advances, the science of consciousness lacks firm conceptual footing. Competing theories not only disagree on mechanisms but also define consciousness in mutually incompatible ways, and criteria for evaluating theoretical success remain vague. I argue that this situation arises from a lack of pragmatic pressure within the field. Theories are rewarded for offering ever...
