Judgments of social appropriateness by children and adolescents with autism.

ABSTRACT

Children and adolescents with autism (autism group, n = 19) and those without autism (Nonautism group, n = 19) of similar age and IQ were asked to make judgments of the social appropriateness of 24 videotaped, staged scenes with adult actors. Each scene depicted an appropriate or an inappropriate interaction. Half contained verbalizations, and half did not. After each scene, the participant was asked (1) Was that o.k. or was something wrong with it? If the participant judged the scene was wrong, she or he was asked (2) What was wrong with it?; and (3) Why was that wrong? Both groups correctly identified inappropriate behaviors most of the time, and correct behaviors almost all of the time. However, the Nonautism group detected inappropriate behaviors significantly more often than the Autism group, for verbal but not nonverbal scenes. It was also significantly easier for both groups to identify inappropriate behaviors in the nonverbal than in the verbal scenes. Ratings of the explanations given for Question 3 differed significantly between the groups for verbal but not for nonverbal scenes, with Nonautism participants more likely to give explanations involving social norms and principles, and the Autism group more likely to give explanations that were irrelevant or idiosyncratic.
