Abstract
The people with autism spectrum disorders (ASD) show various tendencies like difficulty in social interactions and restricted interests and behavior, and atypical audiovisual interaction. Non-diagnosed people are also reported having variable ASD traits. However, it has been not fully investigated the particular relationships between ASD traits and audiovisual interaction. We estimated the degree of ASD traits for non-diagnosed people, and the audiovisual interaction pattern under the stream bounce perception (i.e., a sound enhances bouncing perception when two moving objects overlap). The people with the higher comprehensive ASD traits showed the stronger audiovisual interaction effect. Additionally, the people with the higher ASD traits for the difficulty in social interactions showed the effect even when the sound was presented after the overlap of the visual stimuli. The comprehensive ASD traits and the traits related to social difficulty would have unique effects on the audiovisual interaction under the stream bounce perception.
