Answer:
Attachment; Harry Harlow; warmth and comfort.
Explanation:
Attachment is the positive emotional bond that develops between a child and a particular individual. Harry Harlow conducted a classic study with infant monkeys. They were given the choice of cuddling with a surrogate wire monkey equipped with milk or a surrogate wire monkey covered in soft terry-cloth that did not provide milk. The infant monkeys preferred the warmth and comfort provided by the terry-cloth monkey.
In 1959, Harry Harlow conducted a classic experiment to study the behaviour of infant monkeys that were separated from their mothers at birth, so as to test the effects of the separation on the infant monkeys.
