The controlled laboratory studies of Harry F. and Margaret K. Harlow... separated infant monkeys... in single cages in an animal colony room where they could develop social relationships... through seeing, hearing, and smelling, but not through touching or movement. These and other studies indicate that it is the deprivation of body contact and body movement—not deprivation of the other body senses—that produces the wide variety of abnormal emotional behaviors in these isolation-reared animals.
