Unmistakable Clues Your Child Could Be on the Autism Spectrum

15. Intense Focus on Specific Objects or Topics

One of the most defining characteristics of autism is a deep and intense interest in specific topics. While many children develop strong interests, autistic children often hyperfocus on a particular subject to an extraordinary degree. They might memorize intricate details about dinosaurs, space, trains, or a specific TV show, and spend hours talking about or engaging with that interest. This deep focus can be both a strength and a challenge—while it allows autistic individuals to become experts in their field of interest, it can also make it difficult for them to shift attention to other activities or participate in conversations outside their area of passion.

16. Prefers Parallel Play Over Group Interaction

Many autistic children prefer parallel play—playing alongside other children rather than engaging directly with them. While neurotypical children typically move from parallel play to interactive play by preschool age, autistic children may continue preferring solitary or side-by-side play well into childhood. They might show little interest in joining group games, struggle with turn-taking, or become overwhelmed in social settings. This preference for independent play does not necessarily indicate that they don’t want friends; rather, they may simply interact in a way that feels natural and comfortable to them. With the right support, many autistic children learn social skills at their own pace.
