Recognition and expression of emotional cues by autistic and normal adults

High-functioning autistic adults were compared with normal adults using a battery of tests devised to assess the recognition and expression of emotional cues in both facial and vocal modalities. The autistic subjects were relatively impaired in both the appreciation and production of emotional expressions. Although no one test provided a clear-cut separation of the groups at the individual level, composite scores did separate the groups quite well. It is suggested that this battery of tasks may have some value in family genetic studies of autism that need to identify subclinical deficits that might be aetiologically linked with autism.
