According to some theories imitation, defined as an action resonance mechanism, is deficient in autism. In contrast, other theories (e.g., the ‘‘top down control of imitation’’ hypothesis) state that the problem is not in imitation per se but in the way social cues modulate imi- tative responses. In this study, 15 high-functioning children with autism and 15 matched controls were tested for their ability to imitate finger movements preceded by neutral and emotional facial expressions (primes) in a stimulus– response compatibility task. Hand movements performed after neutral expressions did not differ between the two groups (i.e., they both showed a normal imitative ten- dency). However, hand movements performed after emo- tional expressions significantly differed between the two populations, with controls, but not autistic spectrum dis- order (ASD), showing enhanced imitation in the emotional condition. This study supports the view that, in ASD, imitation abilities are spared but they are not modulated according to the emotional and social context. © 2012 Springer Science+Business Media, LLC.
