Out-of-Body Level of Experience Scale: Construction and First Validation

PsyArXiv December 29, 2025 Patrizio Tressoldi, Bruno Abbondanza, Graham Nicholls et al. preprint

Out-of-body experiences (OBEs), defined as the subjective sensation of having a personal identity separate from one's physical body, have captivated humanity across cultures and throughout history. While artificial induction techniques have provided valuable insights into the neural correlates of bodily self-consciousness, these artificially generated experiences often lack the perceptual and...

The veridical Near-Death Experience Scale: construction and a first validation with human and artificial raters

Our essence? Conscious, Eternal, Infinite, Nonjudgmental, Unconditional Love

July 29, 2023 Patrizio Tressoldi preprint

Which is our fundamental essence? Are we biological machines or spiritual eternal beings? In this essay, I attempt to demonstrate that our essence is nothing else than conscious eternal, infinite, nonjudgmental, unconditional love. This eternal, infinite, non-judgmental unconditional love expresses itself as a never-ending creative force that gives rise to infinite expressions with different...

Is Biological Death Final? Recomputing the Drake-S Equation for Postmortem Survival of Consciousness

International Journal of Transpersonal Studies June 7, 2023 Adam J. Rock, James Houran, Patrizio Tressoldi et al. 8 citations

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...

Dead Reckoning: A Multiteam System Approach to Commentaries on the Drake-S Equation for Survival

International Journal of Transpersonal Studies June 7, 2023 James Houran, Adam J. Rock, Brian Laythe et al. 1 citation

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...

By using the descriptions of the Out-of-Body experiences of 13 participants, we aimed to have a picture of what it is like to be in this particular state of consciousness. All information was grouped according to the following topics: consciousness status, self-boundaries, object perception, color perception, other types of perceptions, interactions with other people or beings, emotions, and...

Two Replication Studies of a Time-Reversed (Psi) Priming Task and the Role of Expectancy in Reaction Times

Journal of Scientific Exploration March 8, 2021 Marilyn Schlitz, Daryl Bem, † Davíd et al. 11 citations

Two experiments involving an international collaboration of experimenters sought to replicate and extend a previously published psi experiment on precognition by Daryl Bem that has been the focus of extensive research. The experiment reverses the usual cause–effect sequence of a standard psychology experiment using priming and reaction times. The preregistered confirmatory hypothesis is that...

Hypno-death-experiences: Death experiences during hypnotic life regressions.

Death Studies 2021 Luciano Pederzoli, Eugenia De Stefano, Patrizio Tressoldi

In this study we analyzed retrospectively a database of 44 alleged death experiences between incarnations, as reported by 36 participants during hypnotic life regression sessions with the same hypnotist. The descriptions of these experiences were evaluated using the Italian version of the Near-Death Experience Scale. A large part of the reported experiences were categorized as "Affective", with...

A preregistered multi-lab replication of Maier et al. (2014, Exp. 4) testing retroactive avoidance.

PLoS One August 31, 2020 Markus A Maier, Vanessa L Buechner, Moritz C. Dechamps et al.

The term "retroactive avoidance" refers to a special class of effects of future stimulus presentations on past behavioral responses. Specifically, it refers to the anticipatory avoidance of aversive stimuli that were unpredictable through random selection after the response. This phenomenon is supposed to challenge the common view of the arrow of time and the direction of causality. Preliminary...

Non-Ordinary Mental Expressions (NOMEs): clues on the nature of the human mind

March 6, 2020 Enrico Facco, Luciano Pederzoli, Patrizio Tressoldi preprint

The aim of this paper is to describe some ostensibly odd, Non-Ordinary-Mental Expressions (NOMEs), that have been considered implausible, illusory or hallucinatory phenomena, possible symptoms of disorders of the neurological or psychological functioning. They include a large variety of phenomena, encompassing hearing voices, seeing presences, communication with non-incarnated entities...

Emergence of qualia from brain activity or from an interaction of proto-consciousness with the brain: which one is the weirder? Available evidence and a research agenda

ScienceOpen Research February 26, 2020 Patrizio Tressoldi, Enrico Facco, Daniela Lucangeli

Abstract This contribution to the science of consciousness aims at comparing how two different theories can explain the emergence of different qualia experiences: meta-awareness, meta-cognition, the placebo effect, out-of-body experiences, cognitive therapy, meditation-induced brain changes, etc. The first theory postulates that qualia experiences derive from specific neural patterns, and the...

Stage 1 Registered Report: Anomalous perception in a Ganzfeld condition - A meta-analysis of more than 40 years investigation.

F1000Research 2020 Patrizio Tressoldi, Lance Storm

This meta-analysis is an investigation into anomalous perception (i.e., conscious identification of information without any conventional sensorial means). The technique used for eliciting an effect is the ganzfeld condition (a form of sensory homogenization that eliminates distracting peripheral noise). The database consists of peer-reviewed studies published between January 1974 and June 2020...

Response to Howard (2018): Comments on ‘A Meta-Reanalysis of Dream-ESP Studies’

University of Derby Online Research Archive. February 8, 2019 Lance Storm, Adam J. Rock, Simon J. Sherwood et al.

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)....

THE NEUROPHENOMENOLOGY OF OUT-OF-BODY EXPERIENCES INDUCED BY HYPNOTIC SUGGESTIONS

International Journal of Clinical and Experimental Hypnosis January 2, 2019 Enrico Facco, Edoardo Casiglia, Benedikt Emanuel Al Khafaji et al. 38 citations

Inducing out-of-body experiences in hypnosis (H-OBEs) offers an almost unique opportunity to investigate them under controlled conditions. OBEs were induced as an imaginative task in a resting condition (I-OBE) or in hypnosis (H-OBE) in a group of 15 high hypnotizable subjects. A 32-channel EEG was recorded, and the spectral power and imaginary coherence of each frequency band and each couple...

On the primacy and irreducible nature of first-person versus third-person information.

F1000Research 2017 Patrizio Tressoldi, Enrico Facco, Daniela Lucangeli

In this essay, we will support the claim that at the current level of scientific advancement a) some first-person accounts cannot be reduced to their third-person neural and psychophysiological correlates and b) that these first-person accounts are the only information to reckon when it is necessary to analyse qualia contents. Consequently, for many phenomena, first-person accounts are the only...

On the Science of Consciousness: Epistemological Reflections and Clinical Implications.

Explore 2017 Enrico Facco, Daniela Lucangeli, Patrizio Tressoldi

Consciousness has been one of the most important and tantalizing issues ever since the origin of philosophy and medicine. The concept of consciousness and the so-called "hard problem" (i.e., the mind-brain relationship) are highly complex topics that have yet to be elucidated, involving the realms of both science and philosophy with profound epistemological implications. In the lively debate on...

Feeling the future: A meta-analysis of 90 experiments on the anomalous anticipation of random future events

F1000Research January 29, 2016 Daryl Bem, Patrizio Tressoldi, Thomas Rabeyron et al. 78 citations

In 2011, one of the authors (DJB) published a report of nine experiments in the Journal of Personality and Social Psychology purporting to demonstrate that an individual's cognitive and affective responses can be influenced by randomly selected stimulus events that do not occur until after his or her responses have already been made and recorded, a generalized variant of the phenomenon...
