Answer :

The statement "Harlow's study involving rhesus monkeys demonstrated that contact comfort is important in attachment" is True.

Here's why:
1. Harlow's study: Psychologist Harry Harlow conducted studies in the mid-20th century that involved rhesus monkeys to understand the importance of contact comfort in attachment.

2. Contact comfort: Harlow's research showed that infant monkeys preferred a surrogate mother that provided softness and warmth (contact comfort) over a wire mother that provided food but lacked comfort. This preference for comfort demonstrated the significance of contact comfort in attachment formation.

3. Importance in attachment: The study concluded that contact comfort, such as cuddling, hugging, and physical closeness, plays a crucial role in forming emotional bonds and secure attachments between infants and caregivers. This finding revolutionized our understanding of attachment theory.

In summary, Harlow's study with rhesus monkeys emphasized the essential role of contact comfort in the development of secure attachments, highlighting the emotional aspect of relationships beyond just basic needs like food.
