Abstract: Objective To explore the impact of facial expression recognition characteristic and affective priming of children with autism spectrum disorders to their facial expression recognition. Method The facial expression recognition rate under different priming conditions with a 4 × 3 repeated measures analysis of variance were analyzed, with combinations of pictures and sound as the affective priming stimuli, with emoticons as the target stimuli. Results There were significant differences in the facial expression recognition of children with autism spectrum disorders among the four expressions which were happy, sad, anger and fear (P＜0.01).No significant difference was found in the recognition rate between no priming and positive priming for the four expressions (P>0.05).There was no significant difference in the recognition rate between no priming and negative priming for happy and sad (P>0.05), the recognition rate of no priming was higher than that of negative priming for anger and fear. Conclusions The expression recognition of children with autism spectrum disorders for happy and sad were better than that for anger and fear.No priming effect had been happened for happy and sad expression recognition.Negative priming effect had been produced for anger and fear expression recognition, but not positive priming effect.

摘要： 目的 探索孤独症谱系障碍儿童面孔表情识别特点及情绪启动对其表情识别的影响。方法 以图片与声音相结合作为情绪启动刺激, 以表情图片作为靶刺激, 对不同启动条件下表情识别率进行4×3重复测量方差分析。结果 孤独症谱系障碍儿童对高兴、悲伤、愤怒、恐惧表情识别存在差异(P＜0.01);四种表情在无启动与正启动下识别率差异均无统计学意义(P>0.05), 高兴、悲伤表情负启动与无启动差异无统计学意义(P>0.05), 愤怒、恐惧表情无启动识别率均高于负启动。结论 孤独症谱系障碍儿童对高兴、悲伤表情识别较好, 对愤怒、恐惧表情识别较差, 对高兴和悲伤表情识别没有产生情绪启动效应, 对愤怒和恐惧表情识别没有产生正启动效应, 但产生了负启动效应。
