Perception of basic emotions from speech prosody in adolescents with Asperger's syndrome.

Asperger's syndrome (AS) belongs to the group of autism spectrum disorders and is characterized by deficits in social interaction, as manifested e.g. by the lack of social or emotional reciprocity. The disturbance causes clinically significant impairment in social interaction. Abnormal prosody has been frequently identified as a core feature of AS. There are virtually no studies on recognition of basic emotions from speech. This study focuses on how adolescents with AS (n=12) and their typically developed controls (n=15) recognize the basic emotions happy, sad, angry, and 'neutral' from speech prosody. Adolescents with AS recognized basic emotions from speech prosody as well as their typically developed controls did. Possibly the recognition of basic emotions develops during the childhood.
