摘要

This study examined automatic processing of emotional faces in individuals with high-functioning Pervasive Developmental Disorders (HFPDD) using an affective priming paradigm. Sixteen participants (HFPDD and matched controls) were presented with happy faces, fearful faces or objects in both subliminal and supraliminal exposure conditions, followed by Japanese ideographs for which the participants provided liking ratings. In the HFPDD group, affective priming was not found in either condition; the control group showed affective priming for both emotional faces under the subliminal condition and only for happy faces under the supraliminal condition. Results suggest that the social deficit in autism may derive in part from a failure in evaluating the emotional significance of emotional faces, a function for which the amygdala plays an important role.
