“…The research literature is replete with studies showing the beneficial effects of behavioral interventions for reducing lower-order restricted and repetitive behaviors in children with ASD (e.g., Boyd, Woodard, & Bodfish, 2013;Cunningham & Schreibman, 2008;Hagopian, Rooker, Zarcone, Bonner, & Arevalo, 2017;Hausman, Kahng, Farrell, & Mongeon, 2009;Kuhn, Hardesty, & Sweeney, 2009;Lam & Aman, 2007;Leon, Lazarchick, Rooker, & DeLeon, 2013;Saini et al, 2016). However, only a small number of studies have evaluated behavioral interventions for higher-order restricted and repetitive behaviors in ASD (e.g., Fisher, Rodriguez, & Owen, 2013;Rispoli, Camargo, Machalicek, Lang, & Sigafoos, 2014), and many of those have focused on food selectivity (e.g., Peterson, Piazza, & Volkert, 2016;Roth, Williams, & Paul, 2010;Wood, Wolery, & Kaiser, 2009). The existing literature demonstrates that response blocking (i.e., extinction; Wolff, Hupp, & Symons, 2013), differential reinforcement of alternative behaviors (DRA) with extinction (Fisher et al, 2013), and functional communication training with extinction (Rispoli et al, 2014) are all effective ways of treating higher-order restricted and repetitive behaviors.…”
