In one situation the wire mother held a bottle with food and the cloth mother held no food. Harlows first observation was that monkeys who had a choice of mothers spent far more time clinging to the terry cloth surrogates even when their physical nourishment came from bottles mounted on the bare wire mothers.

Harlow S Studies On Dependency In Monkeys

Harry harlow shows that infant rhesus monkeys appear to form an affectional bond with soft cloth surrogate mothers that offered no food but not with wire surrogate mothers that provided a food.

Cloth mother experiment. The other was a wire mother covered with soft terry cloth. Harlow was interested in the infants attachment to the cloth diapers speculating that the soft material may simulate the comfort provided by a mothers touch. In the other situation the cloth mother held the bottle and the wire mother had nothing.

Results of the harlow monkey experiment. Based on this observation harlow designed his now famous surrogate mother experiment. Then harlow modified his experiment and made a second.

For this experiment he presented the infants with a clothed mother and a wire mother under two conditions. After observing the baby monkeys over time harlow found that even though the baby monkeys received nourishment from the wire mesh mother they still spent more time cuddling and being affectionate with the terry cloth mother.
