About Harry Harlow

  • Harry Frederick Harlow (October 31, 1905 – December 6, 1981) was an American psychologist best known for his maternal-separation, dependency needs, and social isolation experiments on rhesus monkeys, which manifested the importance of caregiving and companionship to social and cognitive development.
  • He conducted most of his research at the University of Wisconsin–Madison, where humanistic psychologist Abraham Maslow worked with him for a short period of time. Harlow's experiments were controversial; they included creating inanimate surrogate mothers for the rhesus infants from wire and wool.
  • Each infant became attached to its particular mother, recognizing its unique face and preferring it above others.
  • Harlow next chose to investigate if the infants had a preference for bare-wire mothers or cloth-covered mothers.
  • For this experiment, he presented the infants with a clothed "mother" and a wire "mother" under two conditions.
  • In one situation, the wire mother held a bottle with food, and the cloth mother held no food.
  • In the other situation, the cloth mother held the bottle, and the wire mother had nothing.
  • Also later in his career, he cultivated infant monkeys in isolation chambers for up to 24 months, from which they emerged intensely disturbed.
  • Some researchers cite the experiments as a factor in the rise of the animal liberation movement in the United States.
  • A Review of General Psychology survey, published in 2002, ranked Harlow as the 26th most cited psychologist of the 20th century.
