Evaluation of the Social Attention Hypothesis: Do Children with Autism Prefer to See Objects Rather than People?

Abstract

A growing body of research shows that children with autism exhibit selective limitations in their ability to direct their visual attention to social stimuli. The cause of this selective limitation, however, remains unknown. The main purpose of this study is to determine whether the limitations in social attention are influenced by the objects in the environment. Specifically, the study examines the differences in visual attention between children with autism and typically developing (TD) children as they view videos of social interactions under two conditions, with and without objects. The sample consisted of 53 children with autism and 74 TD children, aged between 18 and 36 months. The findings indicated that young children with autism exhibited differences in their social attention compared to their TD peers. The results revealed that the presence of objects did not affect the visual attention differences between the two groups. However, removing objects from the environment positively impacted the social attention of both groups. In the condition without objects, both groups directed more visual attention more toward the Face and Body Areas of Interests (AoIs), whereas in the condition with objects, both groups prioritized looking at the Toy AoI. These findings have important implications for evidence-based decision-making, especially in designing early intervention environments for children with autism.
