Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a combination of atypicalities in social cognition. Previous studies showed that people with autistic traits have atypicality in motion perception on a point-light display by measuring visual event-related potentials (ERPs). Although some studies have focused on the association between motion perception and autistic traits, visual ERPs to biological motion as large as actual person have not been investigated. Measuring brain activity in a real-life environment help us to understand the difficulties showed in daily life by people with autistic traits. In this study, we investigated the association between gait perception and autistic traits by measuring ERPs during video observation of approaching and receding life-sized point-light walkers (PLW s). ERPs were measured using an 8-channel EEG system in 22 adults. The multiple regression analyses were conducted to assess association between the Subthreshold Autism Trait Questionnaire (SATQ) score and the ERP amplitude or latency. As the results, we found that the higher SATQ score could be explained by the longer latency of N1 on the occipitotemporal area. These findings suggested that people with autistic traits have difficulty in perceiving the approach of others in daily life. |
