Verified step by step guidance

1. Understand the context of Harlow's research, which involved studying the effects of social isolation on rhesus monkeys, particularly focusing on their social and emotional development.
2. Recall that Harlow's experiments showed that monkeys raised in total isolation lacked normal social experiences during critical developmental periods.
3. Recognize that due to this lack of social interaction, these isolated monkeys exhibited severe social deficits when reintroduced to other monkeys.
4. Note that these deficits included difficulties in forming social bonds, abnormal social behaviors, and failure to interact normally with peers.
5. Conclude that the correct interpretation of Harlow's findings is that isolated monkeys did not integrate easily or show advanced skills, but rather showed impaired social functioning.
