Recognition of facial expressions and prosodic cues with graded emotional intensities in adults with Asperger syndrome.
Adults with Asperger syndrome miss low-intensity angry or sad faces and high-intensity vocal emotions—assess and teach across intensities and modalities.
01Research in Context
What this study did
Doi et al. (2013) asked adults with Asperger syndrome to judge faces and voices that showed anger or sadness at low, medium, or high strength.
The team used photos and short spoken sentences. Each cue carried the same emotion but at different intensity levels.
Adults gave a label for each item so researchers could see which intensities they missed.
What they found
The adults with Asperger syndrome often missed low-strength angry and sad faces.
They also struggled with high-strength angry and sad voices.
Typical adults scored higher at every level, showing the intensity gap is real.
How this fits with other research
Lecavalier et al. (2006) saw the same pattern in kids: children with Asperger’s were worse at both face and voice emotions. The adult data now show the problem does not fade with age.
Root et al. (2017) looked only at low-strength angry faces in low-functioning children and also found errors. That study seems stricter, but both papers agree subtle anger is hard; the difference is ability level, not a true contradiction.
Globerson et al. (2015) added neurotypical adults and confirmed that pitch-hearing is intact in ASD. Together the two adult studies tell us the trouble is not hearing pitch; it is linking pitch to feeling.
Why it matters
When you teach social skills, show emotions at several intensities and in both face and voice. Do not assume clients will generalize from a big frown to a slight frown, or from a loud angry tone to a quiet one. Build lessons that mix mild and strong examples, and always check both channels.

03Original 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.
