The autistic child's appraisal of expressions of emotion: a further study.

Autistic and matched non-autistic retarded children were selected for their ability to recognize the correspondence between schematic drawings and videotaped scenes involving people. The subjects of both groups were able to choose schematic drawings of gestures for a person's gestures of emotion enacted on videotape. However, the autistic children were significantly impaired in choosing which of the drawings of gestures should 'go with' videotaped vocalizations and facial expressions characteristic of four emotional states. The results were found to be consistent with results from a previous, related study in which the same subjects had chosen drawn or photographed faces to indicate their judgements of the same videotapes of emotional expression. It is suggested that these findings reflect an important aspect of autistic children's social disability.
