What is a behavioral indicator of potential autism spectrum disorder (ASD)?

Difficulty with social interactions or communication challenges is a well-recognized behavioral indicator of potential autism spectrum disorder (ASD). Individuals on the autism spectrum often find it challenging to engage in typical social exchanges, which may manifest as trouble understanding social cues, maintaining conversations, or forming relationships with peers. These communication difficulties can arise in both verbal and non-verbal forms, demonstrating the diverse ways ASD can affect social behavior.

In contrast, the other choices present behaviors that are not typically associated with ASD. Excessive talking and social engagement might indicate effective social skills rather than difficulties. A strong preference for routines with flexibility does not align with the rigidity often found in individuals with ASD, where strict adherence to routines is a common trait. Advanced cognitive skills can also appear in individuals with ASD, but they do not serve as an indicator for the disorder itself, since cognitive abilities can vary widely among those on the spectrum. Thus, the choice related to social interaction difficulties aligns closely with the primary characteristics observed in autism spectrum disorder.
