Abstract

This study investigated the ability of adults with Asperger syndrome to recognize emotional categories of facial expressions and emotional prosodies with graded emotional intensities. The individuals with Asperger syndrome showed poorer recognition performance for angry and sad expressions from both facial and vocal information. The group difference in facial expression recognition was prominent for stimuli with low or intermediate emotional intensities. In contrast to this, the individuals with Asperger syndrome exhibited lower recognition accuracy than typically-developed controls mainly for emotional prosody with high emotional intensity. In facial expression recognition, Asperger and control groups showed an inversion effect for all categories. The magnitude of this effect was less in the Asperger group for angry and sad expressions, presumably attributable to reduced recruitment of the configural mode of face processing. The individuals with Asperger syndrome outperformed the control participants in recognizing inverted sad expressions, indicating enhanced processing of local facial information representing sad emotion. These results suggest that the adults with Asperger syndrome rely on modality-specific strategies in emotion recognition from facial expression and prosodic information.

Notes

  1. The IQ tests were conducted as a part of routine clinical examination, and we did not re-run the WAIS specially for the present study. Therefore, the timing when WAIS was administered varied among the participants with AS. Because of this, the nine participants, who have their IQ scores measured recently, were tested by Wais-3. Some of the participants with AS were introduced to the outpatient clinic, where the present research was conducted, from other medical facilities. The IQ sub-scores of three participants with AS were not fully disclosed or forwarded to Showa University Hospital, which made the IQ sub-scores unavailable for these participants.
