sensory deprivation

Pseudomedicine
The elimination of virtually all external auditory, sensory and visual stimuli, which can be accomplished by immersing oneself in luke-warm water in a flotation tank, or in an isolation (dry) chamber. Advocates of this form of pseudotherapy believe it to be useful for increasing self-awareness; it is also used by those who wish to enhance the intensity of meditation.

The effecting of a major reduction in incoming sensory information. Sensory deprivation is damaging because the body depends for its normal functioning on constant stimulation. Sensory deprivation early in life is the most damaging of all and can lead to severe retardation and permanent malfunctioning of the deprived modality.

deprivation, sensory

The condition produced by a loss of all or most of the stimulation from the visual, auditory, tactile and other sensory systems. Often, deprivation involves only one modality (e.g. vision). Methods used for deprivation include diffusing goggles, white noise, padded gloves, etc. Its effect has shown the necessity of continuous sensory activity to maintain the normal development and functioning of any sensory system.
