Mean RT (in ms) on compatible and incompatible trials, for mouth and eye actions, in the ASC and TD control groups. Error bars represent the standard error of the mean. The difference in RT between the compatible and incompatible trials is a measure of the degree to which observing an action primes its execution, therefore referred to as the ‘automatic imitation’ effect. Participants with ASC and TD control participants displayed equivalent levels of automatic imitation of facial actions.
