This study examined the impacts of sign language training on the communication of two adult brothers with level 3 autism spectrum disorder (ASD). A single-subject, multiple-baseline design was used. Sign language targets were selected based on a parent survey and the participants’ predicted motivation towards the target items. The baseline and intervention were conducted naturalistically in the home. Results indicated that the individual, environment, target signs, reinforcement, and motivation are all factors that play into sign language acquisition for nonspeaking individuals with ASD.
