Which of the following is NOT an example of social impairment in autism?

Excessive sharing of personal information is indeed not typically associated with social impairment in autism. In general, individuals with autism spectrum disorder may struggle with understanding social norms and expectations regarding communication and personal boundaries. While they may often face challenges in understanding when to share or how much to share about themselves, excessive sharing indicates a lack of awareness or understanding of these social boundaries rather than an impairment.

The other options illustrate common characteristics of social impairment in autism. Limited eye contact is a well-documented behavior where individuals may avoid looking directly at others, potentially due to discomfort or difficulty interpreting social cues. Little interest in sharing information reflects a common tendency among individuals on the spectrum to focus on their own interests without engaging others in conversation. Preferential engagement in solitary activities highlights a tendency to seek out activities done alone rather than engaging socially with peers, indicating a preference or comfort in isolation over social interaction.
