“…Although NCR alone has been found efficacious for treating automatically reinforced problem behavior (Buchanan & Fisher, 2002;Piazza, Adelinis, Hanley, Goh, & Delia, 2000;Roscoe, Iwata, & Zhou, 2013), a number of studies have shown that the addition of a punishment procedure (e.g., response cost) was necessary to achieve clinically significant reductions (Bartlett, Rapp, Krueger, & Henrickson, 2011;DeRosa, Roane, Bishop, & Silkowski, 2016;Falcomata, Roane, Hovanetz, Kettering, & Keeney, 2004;Peters & Thompson, 2013;Watkins & Rapp, 2014). Falcomata et al (2004) and Bartlett et al (2011) found that NCR alone did not reduce inappropriate vocalizations and spitting, respectively, to clinically significant levels, and that the addition of response cost resulted in immediate decreases in problem behavior to near-zero levels.…”
