Document Summary
Chapter 12: differential reinforcement procedures to decrease behaviour. Tommy, an 11-year-old boy with a developmental disability, was judged by his teacher to be the most disruptive student in his classroom. He frequently engaged in inappropriate talking and other vocalizations during class occurring at a high rate. A tea(cid:272)he(cid:396)"s assista(cid:374)t lo(cid:272)ated i(cid:374) the (cid:271)a(cid:272)k of the (cid:396)oo(cid:373) (cid:396)e(cid:272)o(cid:396)ded to(cid:373)(cid:373)(cid:455)"s talk-outs during one 50- minute session per day. A second trained observer also recorded to(cid:373)(cid:373)(cid:455)"s talk-outs to ensure the accuracy of the observations. It was found that tommy averaged about one talk-out every 9 minutes. At the end of each session, the teacher told tommy whether he had met the requirement, but during the session, he was never told the number of talk-outs recorded. During phase 2, which lasted 15 sessions, tommy averaged about one talk-out every 54 minutes. Moreover, he never exceeded the upper limit of three per session.
