The Principal Investigator will evaluate all subjects to confirm autistic status. In addition, autistic status will be confirmed with the gold-standard diagnostic measure of autism in adults. Upon enrollment, subjects will meet with the study therapists for three 1-hour preparatory sessions scheduled within the month prior to the first experimental session to discuss what to expect during experimental sessions. In-person visits will occur in a private room at the research facility. All in-person sessions will be video recorded. Video recordings will be used for research and training purposes after the study.
