Abstract

This study investigated whether individuals with high autistic traits rely on psychoacoustic abilities in affective prosody recognition (APR). In 94 college students, Autism Spectrum Quotient (AQ) and psychoacoustic abilities were measured. Results indicated that higher AQ, higher rapid auditory processing (RAP), and maleness were associated with a lower APR accuracy for low-intensity prosodies. There was a strong positive association between RAP and APR for participants with high AQ, whereas low-AQ participants showed no such pattern. The findings suggest a reliance on psychoacoustic abilities as compensatory mechanism for deficits in higher-order processing of emotional signals in social interactions, and imply potential benefits of auditory interventions in improving APR among individuals with high autistic traits.
