What impact does social isolation have on young monkeys, based on the findings of Suomi and Harlow?

The impact of social isolation on young monkeys, highlighted in the studies by Suomi and Harlow, indicates that such isolation can lead to significant long-term socialization issues. Their research demonstrated that young monkeys deprived of social interactions develop abnormal behaviors, struggle to interact with peers, and often exhibit signs of stress or anxiety. This detrimental effect underscores the importance of social relationships in healthy development, suggesting that prolonged isolation disrupts not just immediate social skills but also has lasting consequences that can impair social functioning throughout the animal's life. Thus, it is clear that social isolation has profound consequences on their development and future social interactions.
