AP PSYCHOLOGY

Detailed explanation-1: -In both conditions, Harlow found that the infant monkeys spent significantly more time with the terry cloth mother than they did with the wire mother. When only the wire mother had food, the babies came to the wire mother to feed and immediately returned to cling to the cloth surrogate.

Detailed explanation-2: -Fear, Security, and Attachment Later research demonstrated that young monkeys would also turn to their cloth surrogate mother for comfort and security. Such work revealed that affectionate bonds were critical for development.

Detailed explanation-3: -If a frightening object was placed in the cage the infant took refuge with the cloth mother (its safe base). This surrogate was more effective in decreasing the youngsters fear. The infant would explore more when the cloth mother was present.

Detailed explanation-4: -Harlow demonstrated this fact by giving monkeys two surrogate mothers: a wire mother, who provided nourishment; and a cloth mother, who provided contact comfort. The monkeys always preferred the cloth mother. Harlow’s experiment also showed that mothers and peers are needed for social development.

Detailed explanation-5: -Harlow (1958) modified his experiment and separated the infants into two groups: the terrycloth mother which provided no food, or the wire mother which did. All the monkeys drank equal amounts and grew physically at the same rate.
