Several measures have been designed to assess subjective experiences induced by psychedelic substances or other mind-altering drugs as well as non-pharmacological methods. Recently, two self-report questionnaires have been introduced to measure acute adverse effects following psilocybin ingestion and the phenomenon of ego-dissolution associated with the use of psychedelics, respectively. The...
Transpersonal psychology is the study of human nature that begins with theassumption that humans have potentials that go beyond the limits of their ego andintegrate spiritual experience into a broader understanding of the human psyche andconsciousness. For decades, altered states of consciousness have been used as a form ofpsychotherapy in transpersonal psychology. Although there are well-known...
Rhythm deeply permeates the environment and is perceived by nearly all sensory modalities. There is a developing trend in cognitive science to look to neural rhythms at varying scales as the source of subjective experience. This approach, which looks to the oscillatory correlates of consciousness—electromagnetic field oscillations generated by the brain—as a quantifiable measure of...
Consciousness can be defined by two components: arousal (wakefulness) and awareness (subjective experience). However, neurophysiological consciousness metrics able to disentangle between these components have not been reported. Here, we propose an explainable consciousness indicator (ECI) using deep learning to disentangle the components of consciousness. We employ electroencephalographic (EEG)...
The article describes the ways of conceptualizing the conceivable worlds in altered states of mind at the example of the main character’s conceivable world in Chuck Palahniuk's "Fight Club". From the conducted analysis it can be seen that the world of people in altered states of consciousness can expand significantly. This hypertrophied expansion goes along the axis of space and time. This...
The article summarized the results of the research activity of Andrey Rossokhin, which is devoted to studying the dynamics of reflection in the altered states of consciousness in the course of psychoanalytic process. These states of consciousness are characterized by transformation of the semantic space of the subject and changing forms of categorization with a transition from socially normed...
The Zone is a state of mind/body coordination that is much sought after by athletes because it is so conducive to achieving peak performance. The experience of this state can be so transcendent that some have come to view sport as a spiritual practice. An immensely popular recent movie about competitive chess, The Queen's Gambit, is not overtly about the Zone, addressing such popular themes as...
This retrospective study was a nonrandomized comparison of exercisers' (runners and participants of a spinning class) states of consciousness with subjects of active-alert hypnosis (AAH) and students in a class (control). Three hundred and seventy-five participants completed the Phenomenology of Consciousness Inventory (PCI). Runners, spinners, and participants of AAH scored higher on the...
Substance-induced consciousness alterations (CA) have mainly been studied among users of psychedelics but not among people using street drugs. Explore occurrences of three different types of substance-induced CA [ego dissolution (ED), visual pseudo-hallucinations (VPH), anxiety/paranoia (A/P)] and their perceived influences on life, together with their associations with substance use and...
Near-death experiences (NDEs) including out-of-body experiences (OBEs) have been fascinating phenomena of perception both for affected persons and for communities in science and medicine. Modern progress in the recording of changing brain functions during the time between clinical death and brain death opened the perspective to address and understand the generation of NDEs in brain states of...
Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue...
In this paper, we present the development of the Altered States Database (ASDB), an open-science project based on a systematic literature review. The ASDB contains psychometric questionnaire data on subjective experiences of altered states of consciousness (ASC) induced by pharmacological and non-pharmacological methods. The systematic review follows the Preferred Reporting Items for Systematic...
