Final answer:
Harry Harlow's experiment with monkeys and surrogate mothers emphasized the importance of contact and social comfort over satisfying hunger. The study demonstrated the significance of social bonding for development.
Step-by-step explanation:
Harry Harlow's experiment with monkeys and surrogate mothers emphasized the importance of contact. In his research, Harlow found that baby monkeys preferred a soft, terrycloth surrogate mother over a wire mother that provided food. This demonstrated that social comfort and contact were more important to the monkeys than satisfying hunger. The study highlighted the significance of social bonding and its impact on development.
