title: Does a photographic cue facilitate false belief performance in subjects with autism?
abstract: The posting manipulation, which Mitchell and Lacohée (1991) successfully employed to facilitate false belief (FB) task performance in normally developing 3-year-olds, was employed with subjects with autism. There was no autism-specific impairment on the standard FB task, compared to mental handicap and normal controls: All groups performed poorly, with the autism and normal groups performing significantly worse than chance and the mental handicap group performing at chance. However, a facilitative effect was found on the posting FB task for all subject groups. On the posting task the mental handicap and normal controls groups performed significantly better than chance and the autism group performed at chance. The facilitative effect reached significance for the autism and normal groups. The lack of an autism-specific deficit on the standard task is discussed in relation to the somewhat variable findings of past studies of FB performance in autism. The facilitative effect of the posting manipulation may tell us something about the task demands required to pass a false belief task itself, and suggestions are made for future research to clarify how the facilitative effect operates.
