Autistic children's ability to interpret faces: a research note.

Ten autistic children were compared with 10 non-autistic children matched for chronological age and performance IQ on two tests of finding the odd face out of a set of photographs of faces, two tests of labelling photographs of faces, and a test of labelling photographs of common objects. The autistic children were significantly worse than the non-autistic children at finding the odd person out and the odd facial expression of emotion out, and at labelling facial expressions of emotion. They did no worse than the non-autistic children at labelling upside down faces or at labelling objects. The results, which replicate the findings of Hobson (J. Child Psychol, Psychiat. 27, 321-342, 671-680, 1986; Communication, 20, 12-17, 1986) are consistent with other evidence for a specific perceptual abnormality in at least some children with autism, the nature of which is discussed.
