“…Persons with multiple disabilities (including profound motor impairment) are often unable to interact with their environment and control stimulation opportunities due to very limited response skills (Saunders, Questad, Kedziorski, Boase, Patterson, & Cullinan, 2001;Holburn, Nguyen, & Vietze, 2004;Murphy, Saunders, Saunders, & Olswang, 2004). This condition (a) makes them look passive and largely dependent, (b) reduces their opportunities of constructive engagement and choice, and thus (c) hinders their prospects of personal development as well as their social image and quality of life (Reid, Phillips, & Green, 1991;Ivancic & Bailey, 1996;Lancioni, O'Reilly, & Basili, 2001;Schalock, Brown, Brown, Cummins, Felce, Matikka, Keith, & Parmenter, 2002).…”
