This study was designed to test the prediction that adolescents with autism would have
specific limitations in imitating the “style” of another person's actions. In a series of original
tasks that tested the delayed imitation of novel nonsymbolic actions, 16 participants with
autism and 16 nonautistic participants group-matched for age and verbal ability were
proficient in copying goal-directed actions, but in 3 out of 4 tasks, strikingly fewer
participants with autism imitated with style with which the demonstrator executed the
actions. An additional finding was that on 2 conditions that involved copying self-orientated
actions, only 5 of the participants with autism but 15 of the 16 nonautistic participants
spontaneously adopted the orientation-to-self on at least 1 occasion. The results are
discussed with reference to theories concerning imitation deficits in autism, and with regard
to the proposal that autism involves an impairment in intersubjective contact between
affected individuals and others (Hobson, 1989, 1993; Rogers & Pennington, 1991).
