Six teenagers with Autistic Spectrum Disorders (ASDs) experienced a Virtual Environment (VE) of a cafe. They also watched three sets of videos of real cafe and buses and judged where they would sit and explained why. Half of the participants received their VE experience between the first and second sets of videos, and half experienced it between the second and third. Ten naive raters independently coded participants' judgments and reasoning. In direct relation to the timing of VE use, there were several instances of significant improvement in judgments and explanations about where to sit, both in a video of a cafe and a bus. The results demonstrate the potential of Virtual Reality for teaching social skills.
