Ruffman, Garnham, and Rideout (2001) further investigated links between the Sally–Anne test and autism in terms of eye gaze as a social communicative function. They added a third possible location for the marble: the pocket of the investigator. When autistic children and children with moderate learning disabilities were tested in this format, they found that both groups answered the Belief Question equally well; however, participants with moderate learning disabilities reliably looked at the correct location of the marble, while autistic participants did not, "even if" the autistic participant answered the question correctly. These results may be an expression of the social deficits relevant to autism.
