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.
