Windows to the Social Mind: What Eye-Tracking Reveals About Theory of Mind in Children and Young Adults with Autism...

Human social life is dependent on the ability of individuals to understand other people as separate cognitive agents, capable of thought independent from themselves. This understanding and the attribution of mental states to others, often called Theory of Mind (ToM), is a naturally developing ability. Individuals with Autism Spectrum Disorder (ASD) seem to experience difficulty in attributing mental states to others, and this may explain impaired social interaction and communication behaviors. The Frith-Happé animations are short videos designed to test ToM development by varying the degree of intentionality present and asking viewers to describe their interpretation. The present study recorded eye movements and verbal descriptions in 15 children and 23 young adults with ASD and 20 and 15 typically developing (TD) peers, respectively. The results showed eye movement patterns in ASD and TD children did not differ significantly, but both groups differed from adults in their verbal responses. Children with Autism Spectrum Disorder (ASD) produced shorter (F(1,60) = 5.8, p = 0.019) and less appropriate (F(1,60) = 4.4, p = 0.04) ToM descriptions than TD peers, although their eye movement patterns were comparable to those of TD children. While low-level visual processing may be intact in individuals with ASD, challenges with social cognition and verbal expression may remain.
