Deficits in emotion recognition and social interaction characterize individuals with Asperger's Disorder (AS). Moreover they also appear to be less able to accurately use confidence to gauge their emotion recognition accuracy (i.e., metacognitive monitoring). The aim of this study was to extend this finding by considering both monitoring and control processes in emotion recognition among adults with AS. Those with AS were found to have difficulties acting on the basis of their metacognitive monitoring despite showing no deficits in their ability to discriminate accurate from inaccurate decisions. It is suggested that adults with AS have difficulties interacting socially because they are less able to assess when they are making accurate emotion recognition decisions despite having the capability to do so.
