Question

Harlow and colleagues' studies with infant rhesus monkeys reared in isolation demonstrated that, compared to monkeys reared normally with their mothers, those reared in isolation and then placed with other monkeys:

a) rose into leadership positions due to their aggression but died early of unusual infections.
b) integrated successively, but stayed at the lowest social ranks.
c) were unable to communicate effectively with other monkeys.
d) had overly intense attachments to the other monkeys.

Answer 1

Studies by Harlow and colleagues on infant rhesus monkeys reared in isolation revealed significant developmental and social challenges, showing the necessity for early social contact.

Step-by-step explanation:

Harlow and colleagues' studies with infant rhesus monkeys reared in isolation demonstrated that those reared in isolation, when placed with other monkeys, had a difficult time integrating and displayed various developmental and social challenges. These studies highlighted the importance of early social contact and confirmed that social comfort has a profound impact on healthy psychosocial development. The rhesus monkeys in question formed inadequately intense attachments to their cloth surrogate mothers, indicating that they sought comfort over sustenance. Later in life, their isolation led to significant problems, they did not integrate well socially and had serious difficulties in communicating and interacting with other monkeys. This is reflected in option (c) of the question, wherein these monkeys were described as unable to communicate effectively with other monkeys due to their deprived early social experiences.
