Harlow, Harry Frederick

Harlow, Harry Frederick (1905-1981) was an American psychologist. His studies of the social behavior of monkeys provided new understanding of human behavior and development.

Harlow's research concluded that a mother's love and close social contacts are needed at an early age for the normal development of behavior. He studied the behavior of monkeys that had been taken from their mothers at birth and given dummy mothers made of wire or cloth. The female infant monkeys responded to the dummy mothers as if they were real mothers.

When they got older, however, these female monkeys, who had not experienced the care and affection of their natural mothers, did not know how to be good mothers themselves. Harlow also found that monkeys who were raised alone did not get along well with other monkeys as adults.
