Visual Imagery Produced by Rhythmic Photic Stimulation: Personality Correlates and Phenomenology

Abstract

This study is concerned with relationships between descriptions of visual imagery produced by rhythmic photic stimulation and a number of personality tests. Individuals who manifested the ability to suspend their generalized reality‐orientation described more imagery; imagination and suggestibility also seemed to be important. Subjects' expectations about what they would see influenced their reports, although comprehension of the experimental design, fatigue and motivation were not relevant. The correlated personality variables indicate a close relationship with other types of visual imagery; the phenomenology fits a synthesized description of sensory deprivation, mescaline, and hypnagogic imagery.

Increased spontaneous EEG signal diversity during stroboscopically-induced altered states of consciousness

“…The same applies to some psychogenic or neurological ASC, such as those occurring in Charles Bonnet Syndrome 25,27 . Additionally, as noted by several authors 22,[28][29][30] , SIVH are similar in aspects of perceptual content to the altered visual experiences induced by hallucinogenic drugs. Beyond these perceptual effects, stroboscopic stimulation has also been shown to induce a range of dissociative phenomena including temporary disruptions in awareness, memory or the sense of identity or self 31,32 .…”

“…Further exploratory analyses were carried out to compare signal diversity measures with more standard electrophysiological measures. We computed the average spectral power profile for delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz) and beta (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) Hz) frequency bands, for each condition and participant. As for LZs, for each participant and condition the 10 min recording was divided into non-overlapping 10 s segments.…”

Audio-Visual Entrainment Program as a Treatment for Behavior Disorders in a School Setting

“…AVE affects electroencephalographic (EEG) output (Toman,1940;Walter, 1956;Barlow, 1960;Inouye, Sumitsuji, & Matsumoto, 1979;Kinney, McKay, Mensch, & Luria, 1972;Nogawa, Katayama, Tabata, Ohshio, & Kawahara, 1976;Lesser, Luders, Klem, & Dinner, 1986;Frederick, Lubar, Rasey, Brim, & Blackburn, 1999). It is purported to alter perception and consciousness (Glicksohn,1986;Richardson & McAndrew, 1990;Freedman & Marks, 1965). AVE has been used to improve grade-point average in college students (Budzynski, Jordy, Budzynski, Tang, & Claypoole, 1999).…”

BODY MOVEMENT IN RELATION TO TYPE OF INFORMATION (PERSON- AND NONPERSON-ORIENTED) AND COGNITIVE STYLE (FIELD DEPENDENCE)1

“…Empirical studies on imagery and field dependence are scarce, however. Freedman and Marks (1965) found that field-independents reported a greater variety of objects and color responses in imagery elicited by photic stimulation. Cohen, Silverman, and Shmavonian (1962) reported incidental findings, based on postexperimental self-descriptions, of more intense and frequent imagery among fielddependents during sensory isolation.…”
