Abstract

<p>The study tested 13 individuals with autism spectrum disorder (ASD) and 12 individuals with typical development (TD) using video clips that depicted interactions between an adult actor (who played the “mother” role) and a child. This study aimed to examine the use of pragmatic and relevant information in terms of ASD traits. The results demonstrated that the number of cues used by the participants differed between the two groups in which 60% of the ASD group used only one cue, whereas the majority of the TD group used multiple cues. We then classified all participants into two groups based on the number of cues used. The results of the cue-based analysis illustrated that the single-cue group looked at the eye area of the “mother” less frequently than did the multiple-cue group. The single-cue group exhibited a higher total AQ score and higher subtest scores. These results suggested that a relationship exists between the use of pragmatic information and ASD traits. Thus, we need to consider that information integration may vary according to the degree of ASD traits.</p>
