Book excerpt: The purpose of this study was to compare the effects of sensory deprivation (SD) and perceptual deprivation (PD), each of 4-days duration, on measures of EEG activity, subjective stress, and on 22 different psychological and somatic symptom areas derived from Myers' post-isolation questionnaire. The results revealed that both SD and PD produced a decrease in occipital alpha frequency, an increased degree of subjective stress, and a higher incidence of 16 of the 22 questionnaire-elicited symptoms. Surprisingly, however, virtually no significant differences were observed between the two experimental conditions, a finding contrary to two current deprivation theories which would predict that PD should produce a greater impairment than SD. It was suggested that these negative results may be related to the shortness of the deprivation period. (Author).
