This four hour old Rhesus Macaque (Macaca mulatta) was separated at birth from its mother. These animals afforded Dr. Harlow an ideal subject for the study of the mechanisms of affectional development. Maternal deprivation experiments performed by Harry Harlow of the University of Wisconsin in the 1950's involved separating infant monkeys from their mothers and rearing them with surrogate mothers made of wire or cloth. The monkeys were kept in partial or total isolation, in wire cages or in "pits" or "wells of despair." These experiments found that comfort, security and affection are necessary for a monkey's healthy psychosocial development.
