In a famous series of experiments conducted by Harry Harlow, infant monkeys were separated from their mothers at birth. The infants were then given two surrogate mothers (a terry-cloth "mother" and a wire "mother"), each of which alternately had a nursing bottle that provided food to the infants. The experimental results showed that in frightening situations, the infant monkeys:

Preferred the terry cloth mother even when the wired mother had the nursing bottle.

Explanation:

Harlow was an experimenter who has been investigating the love and affection in human nature. He develops affection, love, care and emotional bond in a person. Harlow conducts a very famous experiment such as on rhesus monkey. The experiment was based on the choice between two mothers.

In this experiment, Harlow raised a monkey after a few hours of birth to another mother. There were two mothers, one was terry soft cloth who did not provide food and another was made from wire but provided food from an attached bottle. In this experiment, the monkey baby spends most of the time with a soft terrycloth mother and go only food to the wire monkey. The result shows that contact comfort was much important for the development of affection.
