Harry Harlow was one of the first psychologists to scientifically investigate the nature of human love and affection. Through a series of controversial monkey mother experiments, Harlow was able to demonstrate the importance of early attachments, affection, and emotional bonds in the course of healthy development. His most famous experiment involved giving young rhesus monkeys a choice between two different “mothers.” One was made of soft terrycloth but provided no food. The other was made of wire but provided nourishment from an attached baby bottle. Harlow removed young monkeys from their natural mothers a few hours after birth and left them to be “raised” by these mother surrogates. The experiment demonstrated that the baby monkeys spent significantly more time with their cloth mother than with their wire mother.
