Autism Spectrum Disorder (ASD) is characterized by impairments in social functioning, communication, and by the presence of repetitive behaviours and restricted interests. Abnormal processing of faces has also been described as a neuropsychological feature of ASD. We investigated the ability to judge two personality traits in adults with ASD in comparison to typically developed adults (TD). We used an eye tracking device to investigate the exploration of faces when participants judged the degree of trustworthiness and dominance of synthetic faces. In sum, we found that adults with ASD were as capable as TD adults to judge personality traits of face trustworthiness and dominance, which relied on similar exploration of the synthetic faces in the two populations.
