Sensory Restriction: Effects on Behavior focuses on the presentation of experimental findings on sensory deprivation and their connection to behavior. The book first offers information on the theoretical framework and physiological effects of sensory restriction. Discussions focus on arousal and the reticular activating system; cortical arousal as a function of level of stimulus variation; possible basis for individual differences in level of arousal; galvanic skin response; biological changes; and other physiological findings. The manuscript also ponders on perceptual and motor effects, affective changes, and differences in tolerance for sensory restriction. Topics include sensory restriction research, therapeutic effects of sensory restriction, and tolerance as a function of need for stimulation. The text also ponders on the effects of social isolation, including individual and small group social isolation. The book is a valuable source of data for readers interested on the effects of sensory restriction on behavior.
