Facial Expression Production and Recognition in Autism Spectrum Disorders

Social "difficulties" associated with ASD may be a product of neurotypical-autistic differences in emotion expression and recognition. Research suggests that neurotypical and autistic individuals exhibit expressive differences, with autistic individuals displaying less frequent expressions that are rated lower in quality by non-autistic raters. Autistic individuals have difficulties recognizing neurotypical facial expressions; neurotypical individuals have difficulties recognizing autistic expressions. However, findings are mixed. Task-related factors (e.g., intensity of stimuli) and participant characteristics (e.g., age, IQ, comorbid diagnoses) may contribute to the mixed findings. The authors conclude by highlighting important areas for future research and the clinical implications of the discussed findings.
