STUDIES ON THE EFFECTS OF PERCEPTUAL ALTERATION

Abstract

Three separate studies explored facets of sensory alteration (sensory deprivation). One study focussed on the role of a diffuse, homogeneous visual field (Ganzfeld) in promoting visual images; the second compared performance on a cognitive test battery immediately following eight hours of perceptual isolation with performances under a drug (100 gamma of LSD-25) and a placebo condition; the third study dealt with the effects upon cognitive functioning of an eight-hour isolation experience, during which constant auditory vigilance was required of the subjects.
