Harry Harlow demonstrated the following in his classic study of attachment among baby monkeys:

B. were more attached to artificial mothers who were warm and soft.

In the experiment, the baby monkeys were more attached to the terry cloth "mother" than the wire "mother" due to the provision of soft warmth and comfort. This experiment provided insight on the importance of the parent-child bond and the importance of maternal touch in the physical, cognitive, social, and emotional growth in infants.
