| Abstract;The implicit processing of emotional faces was examined by means of an affective priming paradigm for individuals with high-functioning autism and Asperger's disorder, who are considered to have deficits in social cognition. Thirteen children and adolescents with HFPDD (high-functioning pervasive developmental disorders) and 13 controls first were presented a prime target (happy and fearful faces or objects), then a neutral target under sub- or supraliminal conditions. The participants were instructed to rate the likability of each target. No affective priming occurred under either exposure condition in the HFPDD group. In the control group, under the subliminal condition fearful faces had a priming effect and under the supraliminal one happy faces had it. Our findings suggest that high-functioning autism and Asperger's disorder are characterized by impairment of the evaluation of emotional significance which normally occurs during the early stage of emotional processing, in which the amygdale has an important function.
