What two areas are primarily characterized by ASD?

The selection of difficulty in social communication and restricted behavior patterns aligns closely with the core characteristics of Autism Spectrum Disorder (ASD).

Individuals with ASD often experience challenges related to social interactions, which can manifest as difficulties in understanding social cues, engaging in conversation, or forming relationships with peers. This aspect of social communication is crucial, as it affects their ability to connect with others in a meaningful way.

Additionally, restricted behavior patterns are a hallmark of ASD, characterized by repetitive behaviors or adherence to routines. This could include a fixation on specific interests, repetitive movements, or resistance to changes in their environment. These behaviors can be significant in how individuals on the spectrum navigate their daily lives and interact with the world around them.

These two areas—social communication difficulties and restricted behavior patterns—are fundamental in diagnosing ASD and understanding the experiences of individuals on the spectrum. The other options, while they might touch upon some related issues or co-occurring conditions, do not encapsulate the defining characteristics of ASD as effectively as the correct choice.
