This study used a choice reaction-time paradigm to test the perceived impairment of facial affect recognition in Asperger's disorder. Twenty teenagers with Asperger's disorder and 20 controls were compared with respect to the latency and accuracy of response to happy or disgusted facial expressions, presented in cartoon or real images and in static or moving conditions. Group analysis revealed that the Asperger group did not differ significantly from the control group in speed and accuracy for both affects and in all presentation modalities. Individual analysis, however, revealed that the proportion of participants exhibiting a happy face advantage was smaller in the Asperger group than in the control group. The results did not support the notion of impairment in facial affect recognition in terms of speed and accuracy in Asperger's disorder. Findings also revealed that the absence of happy face advantage was more prevalent in individuals with Asperger's disorder.
