Question

Quizplus · Accepted Answer

The Harlow experiments demonstrated that monkeys who were isolated for six months were highly fearful when returned to others of their kind. This suggests that social isolation had a significant and negative impact on their social behavior. Option B is partially correct, as monkeys who had an artificial mother were able to develop normally, but this only applied to monkeys who had some form of social interaction, albeit mechanical. Option C is incorrect, as several days of social isolation did not result in permanent damage. Option D is also incorrect, as the experiments showed that the monkeys could distinguish between an artificial and authentic mother based on the comfort they provided.
