这项研究测试了一种假设，即在自闭症谱系障碍(ASD)儿童中，眼神接触引起的情感唤醒与面孔识别技能呈负相关。参与者是20名患有自闭症的儿童和青少年，以及20名年龄和智商匹配的典型发育中(TD)儿童。皮肤传导反应(SCR)是自主神经唤醒的一种心理生理学指标，当参与者观看凝视指向他们的面孔和避开凝视的面孔时，研究人员收集了这一数据。参与者还完成了一项独立的匹配样本人脸识别测试。与TD儿童相比，ASD儿童对直接和回避凝视面孔的SCR显著增大。两组在直接凝视和回避凝视上的SCR均无差异。与TD儿童相比，ASD儿童的人脸识别准确率略有下降，特别是当人脸识别依赖于面部的眼睛区域时。ASD儿童的人脸识别正确率与直接注视的SCR波幅呈负相关，而与回避注视的SCR波幅无关。在TD组中，人脸识别准确率与凝视的SCR之间没有关联。这些发现表明，对眼神接触的自主反应可能会干扰一些自闭症儿童的面部认同处理。(JINS，2008，14,947-955。)
This study tested the hypothesis that affective arousal in response to eye contact is negatively associated with face identification skills in children with autism spectrum disorder (ASD). Participants were 20 children and adolescents with ASD and 20 age- and IQ-matched typically developing (TD) children. Skin conductance response (SCR), a psychophysiological measure of autonomic arousal, was collected while participants viewed faces with gaze directed toward them and faces with gaze averted away from them. Participants also completed an independent match-to-sample face recognition test. Children with ASD exhibited significantly larger SCRs than TD children to faces with direct and averted gaze. There were no differences between SCRs to direct gaze and averted gaze in either group. Children with ASD exhibited a marginally significant decrease in face recognition accuracy relative to TD children, particularly when face recognition depended oil the eye region of the face. Face recognition accuracy among children with ASD was negatively correlated with the amplitude of SCRs to direct gaze but not to averted gaze. There was no association between face recognition accuracy and SCRs to gaze in the TD group. These findings suggest that autonomic reactivity to eye contact may interfere with face identity processing in some children with ASD. (JINS, 2008, 14, 947-955.)
