研究探讨了面部表情特征的变化对孤独症儿童面孔情绪表情识别的影响。19名孤独症儿童和21名普通儿童参加实验。实验分别操纵了情绪表情的强度和呈现速度,观察儿童识别不同类型情绪表情的正确率和反应时。结果表明,孤独症儿童对情绪表情的识别表现与普通儿童存在差异,对快乐表情的识别较快,对高强度的和慢速呈现的面孔情绪识别成绩更好。与普通发展儿童相比,孤独症儿童存在一定的情绪识别困难,并受到面孔刺激呈现特征的影响。

The present study aims to explore how the changes of emotional expressions affect autistic children＇ s facial expression recognition, by testing 19 autistic children and 21 typically developing children based on the manipulation of the intensity and the speed of their emotional expressions to observe their accuracy and reaction time in their identification of different types of facial expressions. The results show the following： There was difference in the identification of facial expressions between the autistic children and the typically developing children, with the former showing faster identification of happy expressions, and scoring high in their identification of high-intensity and slowly presented facial expressions; and compared with the typically developing children, the autistic children found difficulty in recognizing facial expressions, and were affected by facial stimuli.
