Harlow Was Interested in Exploring Why Infants Develop Attachments by Separating

Harlow was interested in exploring why infants develop attachments by separating infant rhesus monkeys from their mothers shortly after birth. He then tested them to see what type of artificial surrogate mother they would prefer to spend their time. He found that the infant monkeys spent time with:

A) the terry cloth surrogate more often because it provided contact comfort for the infant monkeys
B) the bare wire surrogate with the feeding bottle more often because the food provided reinforcement to the infant monkeys
C) both surrogates equally and frequently as each provided for a different need
D) neither surrogate recognizing that the artificial surrogates could not replace their mother
