Sensory deprivation experiments of the 1950s have shown that human
beings need environmental stimulation to function normally. In a
classic early experiment, college students lay on a cot in a small,
empty cubicle nearly 24 hours a day, leaving only to eat and use the
bathroom. They wore translucent goggles that let in light but
prevented them from seeing any shapes or patterns, and they were
fitted with cotton gloves and cardboard cuffs to restrict the sense of
touch. The continuous hum of an air conditioner and U-shaped pillows
placed around their heads blocked out auditory stimulation.
Initially, the subjects slept, but eventually they became bored,
restless, and moody. They became disoriented and had difficulty
concentrating, and their performance on problem-solving tests
