Abstract

Previous studies have shown that people with autistic traits have difficulties in motion perception, such as human gait as depicted on a point-light display. A recent study reported that adults with autism spectrum disorders showed atypical visual event-related evoked potentials (ERPs) in response to radial optic flow. To determine the correlation between gait perception and autistic traits in the general population, the present study recorded ERPs time-locked to the onset of approaching and receding point-light walkers. ERPs were measured using an 8-channel system in 19 adults and the correlation between the ERP components and the Subthreshold Autism Trait Questionnaire (SATQ) score were assessed to quantitatively measure autistic traits in the general population. The results showed that the higher SATQ score was, the longer the latency of the ERP component for an approaching walker was. In conclusion, people with autistic traits have trouble perceiving the approach of other people.
