“…Now, many individuals who use AAC expect to be full participants in a wide range of environments -family, school, work, and community (McNaughton & Kennedy, 2010). Children with cerebral palsy, ASD, Down syndrome, and other developmental disabilities are using AAC to participate in general education classrooms, to learn literacy skills, and to interact with friends and family members (e.g., Anderson, Balandin, & Clendon, 2011;Light & McNaughton, 2009Kent-Walsh & Light, 2003;Finke, McNaughton, & Drager, 2009;Stoner, Angell, & Bailey, 2010). Adults with severe disabilities are living in the community and using AAC to participate in employment, to volunteer, and to take part in recreational activities (e.g., McKelvey et al, 2012;McNaughton, Light, & Arnold, 2002;McNaughton, Light, & groszyk, 2001;Dattilo, Estrella, Estrella, Light, McNaughton, & Seabury, 2008;Trembath et al, 2010).…”
