自闭症谱系障碍（ASD）是一种以社会认知障碍为特征的神经发育障碍。以往的研究通过测量视觉事件相关电位（ERPs）发现，具有孤独症特征的人在点光源显示器上的运动知觉中具有特异性。虽然一些研究集中在运动知觉和自闭症特征之间的联系，视觉ERPs的生物运动作为实际的人还没有调查。在现实生活环境中测量大脑活动有助于我们了解自闭症患者在日常生活中表现出的困难。在这项研究中，我们调查了步态知觉和自闭症特征之间的关联，通过测量ERP在视频观察接近和后退的真人大小的点光步行者（PLW）。用8导脑电系统对22例成人进行了ERPs测定。采用多元回归分析评估阈下孤独症特质问卷（SATQ）评分与ERP波幅或潜伏期之间的关系。结果发现，高SATQ分数可以解释为枕颞区N1潜伏期较长。这些发现表明，患有自闭症的人在日常生活中难以感知他人的接近。
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.
