自闭症儿童面孔觉察与面部表情加工的眼动研究

The Eye-tracking Studies on the Face Perception and the Facial Expression Processing for Autistic Children

为了解面孔熟悉度是否影响自闭症儿童的面孔知觉能力和面部表情加工方式,采用眼动仪对14名3~6岁的自闭症儿童进行实验。实验结果发现,在语义背景不一致情况下,自闭症儿童更容易发现熟悉面孔,并对其有较高的注视率;而在乱序背景下,自闭症儿童对消极表情照片发现的时间要显著少于对平静表情照片所用的时间。

In order to explore whether facial familiarity affects the face perception and facial expression processing for autistic children, 14 autistic children aged 3 to 6 years old （4 in high speech group and 8 in low speech group） are enrolled in the experiment using eye movement system. The results show that autistic children are more likely to find familiar faces and have a higher rate of attention in the inconsistent semantic context;in the context of disorder,autistic children find the negative expression much quickly than calm expression from the photos.
