Harry Frederick Harlow was an American psychologist known the controversial experiments conducted in the 1950s about maternal separation, dependency needs, and social isolation conducted on rhesus monkeys. In order to observe how isolation and separation will affect their behavior and development, he conducted this experiment by placing baby rhesus monkeys to a nursery setting away from their biological mothers within 6 to 12 hours after being born and likewise he introduces a (two) surrogate mother (made of heavy wire mesh and the other made of wood that was covered in terry cloth) as a replacement for their biological mothers. His theory was that the relationships formed between infants and mothers emotional rather than physiological. The terry cloth surrogate mother has a soft to the touch body and appeared to be cuddly, while the wire mesh surrogate mother did not have any soft surface. Therefore as the experiment proceeds Harlow found that the monkeys would turn to their surrogate mother (terry cloth surrogate mother) for comfort than the wire mesh surroagte even though some of the monkeys got their food and nutrition for it.

For his research on monkeys, Harlow found monkeys would turn to their surrogate mother for comfort and security.
