Define "restricted interests" in the context of Autism Spectrum Disorder.

In the context of Autism Spectrum Disorder, "restricted interests" refer to an intense focus on specific topics or activities that may be narrow in scope. This characteristic is a core component of ASD, where individuals often develop strong attachments to certain subjects, such as trains, dinosaurs, or particular types of technology. This focus can manifest in various ways, from collecting information and memorizing details about the interest to spending considerable time engaged in related activities.

Such focus can benefit the individual by providing a sense of comfort and routine; however, it may also limit their engagement in a broader range of activities or topics, which could impact social interactions and flexibility in responding to new situations. The defined focus often leads to depth over breadth in interests, distinguishing this behavior as a hallmark of ASD.
