同情和观点采择方面的缺陷是自闭症谱系障碍的定义特征。越来越多的证据表明，这些社会情感能力植根于促进模仿行为的基本机制，并且可能随着整个人群的自闭症特征而变化。我们调查了这一概念，通过评估自发和指示模仿面部表情的健康男性和女性志愿者得分极高或极低的自闭症谱系问卷。模仿是用皱眉肌和大颏肌的肌电图记录的。结果表明，自发模仿在皱眉肌是最强的女性参与者与低AQ-scores。在大背阔肌的模仿，并在指示面部模仿条件下，没有组间差异。这些发现表明，个体表现出自发模仿的程度可能因性别和自闭症特征而异。(C)2008 Elsevier B. V.保留所有权利。
Deficits in empathizing and perspective taking are defining characteristics of autism-spectrum disorders. Converging evidence suggests that these socio-emotional abilities are rooted in basic mechanisms that subserve imitative behavior, and may vary with autistic traits across the population as a whole. We investigated this notion by assessing spontaneous and instructed mimicry of facial expressions in healthy male and female volunteers scoring extremely high or low on the autism-spectrum quotient questionnaire. Mimicry was recorded using electromyography of the corrugator supercilii and zygomaticus major. Results show that spontaneous mimicry in the corrugator supercilii was strongest in female participants with low AQ-scores. Mimicry in the zygomaticus major, and in the instructed facial mimicry condition, did not differ between groups. These findings indicate that the degree to which individuals exhibit spontaneous mimicry may vary as a function of both gender and autistic traits. (C) 2008 Elsevier B.V. All rights reserved.
