    Abstract:

    Objective To explore the recognition ability and abnormal processing characteristics to basic emotional faces in the early phase in children with autism spectrum disorders (ASD).Methods Photos of Chinese static faces with four basic emotions (fearful, happy, angry and sad) were used as stimulus. Twenty-five ASD children and twenty-two age-and gender-matched typical developed children (normal controls) were asked to match the emotional faces with words. Event-related potential (ERP) data were recorded concurrently.Results N170 latencies for total emotion and fearful face in the left temporal region were faster than in the right one in normal controls (P < 0.05), but the results were not noted in ASD children. Further, N170 latencies in the left temporal region of ASD children were slower than normal controls for total emotion, fearful and happy faces (P < 0.05), and their N170 latencies in the right temporal region were prone to slower than normal controls for angry and fearful faces.Conclusions The holistic perception speed of emotional faces in the early cognitive processing phase in ASD children is slower than normal controls. The lateralized response in the early phase of recognizing emotional faces may be aberrant in children with ASD.
