D. were socially isolated, unable to communicate with other monkeys, and incapable of caring for their young.
Explanation:
Attachment theory is an emotional bond that connect one person to another. Monkeys reared in Isolated Monkey have not been connected with other monkeys rared and have not experience how to get attached or care for the young. It has not been registered in their mind to act the way other do hence a difference between the Isolated and the reared once.
During the "Harlow and Colleagues" experiment, when the monkeys which were reared in isolation were reintroduced into the group of other normally bred monkeys, they were unable to communicate effectively.
Their years in isolation had deprived them of the ability to interact and communicate with other monkeys. Unable to communicate and socialise, they shied away from other monkeys and starved to death because they refused to eat.
When the sympathetic and parasympathetic systems are in balance, the tendency is to rest often and easily allowing for renewal and healing to the body. The balance between the two systems is a key step toward greater health and wellness!
