sensory deprivation in Culture

sensory deprivation

A natural or experimentally arranged situation in which stimulation of a subject's senses is greatly reduced. Experiments have included floating subjects in soundproof water chambers. Though short periods of sensory deprivation can be relaxing, extended deprivation can result in extreme anxiety, hallucinations, bizarre thoughts, depression, and antisocial behavior. Sensory deprivation experiments have demonstrated that humans need constant sensory contact with their environment in order to function.
