Which factor is NOT mentioned as contributing to social skill deficits?

The answer is identified as excessive parental supervision, as it is not typically categorized as a direct contributor to social skill deficits. Social skills often develop through observation and interaction with peers, where children learn appropriate behaviors and social cues.

In contrast, a lack of suitable role models can hinder the development of necessary social skills because children may not have individuals to emulate or learn from regarding social interactions. Similarly, a lack of opportunity to observe behaviors restricts children from witnessing and understanding how to engage in social situations effectively. Cultural differences can also influence social skill development, as varying cultural backgrounds may dictate different norms and expectations for social interaction.

Excessive parental supervision might limit a child's opportunities for independent interaction but is less frequently discussed as a root cause of social skill deficits compared to the other factors listed. It is more about the balance of guidance and independence during a child's social development. Thus, it does not have the same direct association with deficits in social skills as the other mentioned factors.
