“…Winter-Messiers (2007) suggested using strengthbased interventions in which the special interests of children with ASD are used in positive ways to enhance their performance. In some studies, the special interests of these children were used as contingent reinforcers to increase task performance or decrease the inappropriate behaviours of children with ASD (Charlop-Christy & Haymes, 1996. Other studies incorporated the restricted interests of these children into activities or interventions to teach skills (Angell, Nicholson, Watts, & Blum, 2011;Baker, 2000;Baker, Koegel, & Koegel, 1998;Campbell & Tincani, 2011;Keeling, Myles, Gagnon, & Simpson, 2003;Koegel et al, 2012;Spencer, Simpson, Day, & Buster, 2008).…”
