Harlow's monkeys

Harlow’s monkeys experiment demonstrated the importance of emotional contact in development. Researchers provided infant monkeys with two surrogate mothers: one made of wire that delivered food, and another covered in soft cloth that offered comfort. The monkeys preferred cuddling the cloth mother, especially when frightened, highlighting that contact comfort is crucial for psychological well-being. The study showed that social and emotional needs are fundamental, not just physical nourishment, and influenced understanding of attachment, development, and the importance of nurturing relationships in both animals and humans.
