Abstract
Nine people from the high functioning end of the autistic spectrum and eight non-handicapped controls matched on verbal IQ were given two tests of second-order false belief understanding. On the basis of previous research, it was hypothesised that the subjects with autism used different mechanisms to process mental state and non-mental state questions and that this difference would be reflected in a significant group by question type interaction in the reaction times to the two types of question. Although the results showed that the autistic subjects had longer reaction times to questions than controls, there was no evidence for differential reaction times for mental state and non mental state questions for either group.
