Abstract

Autism involves a basic impairment in social cognition. This study investigated early stage face processing in young children with autism by examining the face-sensitive early negative event-related brain potential component in 3-4 year old children with autism spectrum disorder (ASD), typical development, and developmental delay. Results indicated that children with ASD showed a slower electrical brain response to faces and a larger amplitude response to objects compared to children with typical development and developmental delay. These findings indicate that children with ASD have a disordered pattern of brain responses to faces and objects at an early age.

摘要

自闭症涉及社会认知的基本损害。本研究通过检测患有自闭症谱系障碍(ASD)、发育正常和发育迟缓的3至4岁儿童中对面部敏感的早期负性事件相关脑电位成分,调查了自闭症幼儿的早期面部加工情况。结果表明,与发育正常和发育迟缓的儿童相比,患有ASD的儿童对脸部的脑电反应较慢,对物体的反应幅度较大。这些发现表明,患有ASD的儿童在幼年时对脸部和物体的脑反应模式紊乱。
