Parental perception of emotional expressiveness in children with autism.

Parents' perceptions of their children's emotional expressiveness, and possible bases for these perceptions, were investigated in a study comparing older, nonretarded autistic and normal children and in another study comparing young autistic, mentally retarded, and normal children. Both groups of autistic children were perceived as showing more negative emotion and less positive emotion than comparison children. In the younger sample, parental perceptions correlated with the children's attention and responsiveness to others' displays of emotion in 2 laboratory situations. Findings contradict the view that autism involves the "absence of emotional reaction" (American Psychiatric Association, 1987, p. 35).
