‘Positive’ and ‘Negative’ Aspects of the ‘Altered States of Consciousness’ Induced by Autogenic Training, Zen and Yoga

Psychotherapy and Psychosomatics February 16, 2010 Yujiro Ikemi, Hitoshi Ishikawa, J.R.M. Goyeche et al.

As practices of altered states of consciousness (ASC) have become more widely used among psychotherapists who have become aware of the limitations of psychoanalytic, educational and behavioral approaches, negative aspects (‘Makyo’) of ASC have drawn their special attention. For the purpose of controlling or preventing these side-effects, (1) the problem of indication is most important, (2) and...

Altered States of Consciousness and Mystical Experiences during Sensory Isolation in Flotation Tank: Is the Highly Sensitive Personality Variable of Importance?

Imagination, Cognition and Personality October 1, 2009

The aim of this study was to investigate if the highly sensitive personality variable affects the occurrence of mystical experiences and degree of altered states of consciousness during sensory isolation in flotation-tank. Forty-eight persons (20 males, 28 females) were included. Background variables and the Highly Sensitive Personality Scale (HSP) were assessed. The independent variable was...

A Shaman's Cure: The Relationship Between Altered States of Consciousness and Shamanic Healing1

Anthropology of Consciousness September 1, 2009 H. Sidky 23 citations

ABSTRACTThis study, which is based upon ethnographic data collected between 1999 and 2008 in Nepal, examines the connection between the shaman's altered states of consciousness (ASC; i.e., what goes on inside the healer's mind/brain) and therapeutic changes that take place in the patient's mind/body. Unlike other studies that primarily emphasize the shaman's internal psychological state, this...

A Kappa Opioid Model of Atypical Altered Consciousness and Psychosis: U50488, DOI, AC90179 Effects on Prepulse Inhibition and Locomotion in Mice

Journal of young investigators July 1, 2009 Michael A Ruderman, Susan B Powell, Mark A. Geyer

Sensorimortor gating and locomotion are behaviors that reflect pre-attentive sensory filtering and higher order, top-down, sensory processing, respectively. These processes are thought to affect either the perception of novelty in an environment (filtering) or cognition (higher order processing), salient features of models of altered states of consciousness (ASC). Drugs with highly selective...

Opening the Doors of Perception: Priming Altered States of Consciousness outside of Conscious Awareness

Archive for the Psychology of Religion May 1, 2009 Brandon Randolph-Seng, Michael E. Nielsen

Two studies are reported in which participants’ reports of altered states of consciousness (ASC) were manipulated using priming methods. Study 1 used both subtle and blunt supraliminal priming methods, while Study 2 used a subliminal priming method. Across the two studies, two different methods for inducing ASC were used. In both studies a direct and an indirect measure of ASC was employed in...

The use and function of altered states of consciousness within dance/movement therapy

May 1, 2009 Amberlee Woods, Ellen Schelly Hill 1 citation

The purpose of the study was to research trance and altered states of consciousness (ASC), within dance, psychotherapy and anthropological literature, so that dance/movement therapists may practice with an informed understanding of the altered state experience, its potential therapeutic benefit, and methods for working with altered states in the practice of dance/movement therapy (DMT). The...

The Nightmares of Puerto Ricans: An Embodied ‘Altered States of Consciousness’ Perspective

Culture, Medicine, and Psychiatry March 27, 2009 C. Jacobson

This article examines nightmare narratives collected as part of a person-centered ethnographic study of altered states of consciousness (ASCs) and supernaturalism in a mainland Puerto Rican community in the late 1990s. Utilizing a descriptive backdrop informed by cross-cultural studies of ASCs and highlighting the relevance of recent insights from the cognitive sciences of religion and from the...

Theoretical approaches to the diagnosis of altered states of consciousness

Progress in Brain Research 2009 Melanie Boly, Marcello Massimini, Giulio Tononi 50 citations

Assessing the level of consciousness of noncommunicative brain-damaged patients is difficult, as one has to make inferences based on the patients' behavior. However, behavioral responses of brain-damaged patients are usually limited not only by their cognitive dysfunctions, but also by their frequent motor impairment. For these reasons, it is essential to resort to para-clinical markers of the...

Intrinsic Brain Activity in Altered States of Consciousness

Annals of the New York Academy of Sciences May 1, 2008 Melanie Boly, Christophe Phillips, Luaba Tshibanda et al. 396 citations

Spontaneous brain activity has recently received increasing interest in the neuroimaging community. However, the value of resting-state studies to a better understanding of brain-behavior relationships has been challenged. That altered states of consciousness are a privileged way to study the relationships between spontaneous brain activity and behavior is proposed, and common resting-state...
