Abstract: It is well established that neurotypical individuals generally show better memory for actions they have performed than actions they have observed others perform or merely read about, a so-called ‘enactment effect’. Strikingly, research has also shown that neurotypical individuals demonstrate superior memory for actions they intend to perform in the future (but have not yet performed), an effect commonly known as the ‘intention superiority effect’. Although the enactment effect has been studied among people with autism spectrum disorder, this study is the first to investigate the intention superiority effect in this disorder. This is surprising given the potential importance this issue has for general theory development, as well as for clinical practice. As such, this study aimed to assess the intention superiority and enactment effects in 22 children with autism spectrum disorder, and 20 intelligence quotient/age-matched neurotypical children. The results showed that children with autism spectrum disorder demonstrated not only undiminished enactment effects in recognition and source memory, but also (surprisingly for some theories) typical intention superiority effects. The implications of these results for theory, as well as clinical practice, are discussed.
