为探寻自闭症儿童在识别低强度(10%,30%)、中强度(40%,60%)和高强度(70%,90%)的愤怒和开心面部表情时,识别情绪类型的既有能力和差异.采用表情标签范式,用E-prime软件在电脑上呈现不同强度的3D合成面部表情刺激,分别对10名自闭症儿童、10名正常发育儿童和10名智障儿童进行了实验研究.结果发现,自闭症儿童在低强度表情时具有面部表情识别障碍,其对不同强度面部表情识别正确率显著低于智障儿童和正常发育儿童;自闭症儿童面部表情识别正确率与面部表情强度呈正相关,面部表情强度越大,自闭症儿童面部表情识别的正确率越高;自闭症儿童对低强度面部表情识别时,对开心表情的识别正确率高于愤怒表情,但是,在中强度和高强度面部表情识别时,存在显著的愤怒优势效应.%In order to explore the ability and the difference of the emotion types of the children with autism in the recognition of low intensity (10%, 30%), moderate intensity (40%, 60%) and high intensity (70%, 90%) of anger and happy facial expressions. The expression label paradigm, using E-Prime software on the computer show different strength of synthetic 3D facial expression stimulus, respectively for 10 autistic disorder children and 10 normal child development and 10 mentally retarded children were experimentally investigated. Results found that autistic disorder children in low intensity expression is a dysfunction in recognition of emotional facial expressions, the different strength of facial expression recognition correct rate was significantly lower than that of mentally retarded children and normal development of children; autistic disorder children with facial expression recognition correct rate and facial expression intensity was positively related, facial expression intensity bigger, autistic disorder children with facial expression recognition correct rate is higher; autistic disorder in children of low intensity of facial expression recognition, to happy expression recognition correct rate is higher than the expression of anger, however, in strength and high strength for facial expression recognition, there significant anger superiority effect.
