本研究采用事件相关电位（ERP）研究了注视方向对ASD儿童和非ASD儿童面部表情加工影响的神经基础。ASD儿童（10-17奥尔兹）和典型发育（TD）儿童（9-16奥尔兹）被要求确定面部刺激的情绪表达（愤怒或恐惧），并同时记录ERPs。在TD儿童中，在接近-回避动机中具有一致表情和注视方向的面孔，例如具有直接注视的愤怒面孔（即，接近的动机）和具有避开的凝视的恐惧的脸（即，回避动机），更准确地识别，并引起更大的N170振幅比动机不一致的面部刺激（愤怒的脸与回避的目光和恐惧的脸与直接的目光）。这些结果证实了TD儿童面部表情和注视方向整合的神经基础和时间过程以及ASD儿童面部表情和注视方向整合的受损。(C)2010爱思唯尔有限公司版权所有。
This study investigated the neural basis of the effect of gaze direction on facial expression processing in children with and without ASD, using event-related potential (ERP). Children with ASD (10-17-year olds) and typically developing (TD) children (9-16-year olds) were asked to determine the emotional expressions (anger or fearful) of a facial stimulus with a direct or averted gaze, and the ERPs were recorded concurrently. In TD children, faces with a congruent expression and gaze direction in approach-avoidance motivation, such as an angry face with a direct gaze (i.e., approaching motivation) and a fearful face with an averted gaze (i.e., avoidant motivation), were recognized more accurately and elicited larger N170 amplitudes than motivationally incongruent facial stimuli (an angry face with an averted gaze and a fearful face with a direct gaze). These results demonstrated the neural basis and time course of integration of facial expression and gaze direction in TD children and its impairment in children with ASD. (C) 2010 Elsevier Ltd.
