In sensory deprivation studies, researchers were interested in what would happen if our senses adapted to most incoming stimuli. Explain the findings of the early studies in sensory deprivation. What has been revealed by later research?

What will be an ideal response?

Answer: A good answer will include the following key points.
• In early studies of sensory deprivation, researchers isolated male volunteers from all patterned sight and sound.
• Within a few hours, most of the men felt edgy and many were so disoriented that they quit the first day.
• Those subjects that continued became confused, restless, and grouchy, and many experienced hallucinations.
• Later research, using better methods, showed that hallucinations are less frequent and less disorienting than had first been thought.
• Some perceptual and intellectual abilities may actually improve.
• The response to sensory deprivation depends on expectations and interpretations.
• Those who voluntarily engage in limited periods of sensory deprivation may find it to be relaxing.
