摘要
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and interaction, and restricted interests and behavior patterns. These characteristics are considered as a continuous distribution in the general population. People with ASD show atypical temporal processing in multisensory integration. Regarding the flash-beep illusion, which refers to how a single flash can be illusorily perceived as multiple flashes when multiple auditory beeps are concurrently presented, some studies reported that people with ASD have a wider temporal binding window and greater integration than typically developed people; others found the opposite or inconsistent tendencies. Here, we investigated the relationships between the manner of the flash-beep illusion and the various dimensions of ASD traits by estimating the degree of typically developed participants' ASD traits including five subscales using the Autism-Spectrum Quotient. We found that stronger ASD traits of communication and social skill were associated with a wider and narrower temporal binding window respectively. These results suggest that specific ASD traits are differently involved in the particular temporal binding processes of audiovisual integration.
