“…Two of the interventions that have received the most empirical support to reduce engagement in stereotypy in children with ASD are noncontingent access to preferred stimuli and differential reinforcement (DiGennaro Reed et al, 2012). Noncontingent access is designed to reduce engagement in problem behavior by providing continuous or regular access to preferred items (e.g., music, toys, activities) that substitute or compete with the targeted behavior (Britton, Carr, Landaburu, & Romick, 2002; Carr, Severtson, & Lepper, 2009; Hansen & Wadsworth, 2015; Higbee, Chang, & Endicott, 2005; Lindberg, Iwata, Roscoe, Worsdell, & Hanley, 2003; Rapp et al, 2013; Roane, Kelly, & Fisher, 2003; Saylor, Sidener, Reeve, Fetherston, & Progar, 2012). For example, Higbee et al (2005) provided noncontingent access to items that produced visual stimulation to reduce motor stereotypy (i.e., moving fingers in front of eyes) in a child diagnosed with ASD and severe intellectual disability.…”
