Resurgence of problem behavior following the discontinuation of differential reinforcement of alternative behavior (DRA) may be prevented by response-independent reinforcer delivery. In basic research, response-independent reinforcer delivery following DRA prevented resurgence of the initially reinforced response and maintained alternative responding (Lieving & Lattal, 2003, Experiment 3). We evaluated the generality of these results by assessing if fixed-time (FT) reinforcer delivery following DRA would prevent resurgence of problem behavior and maintain appropriate behavior with 4 children with disabilities. For all participants, extinction following DRA produced resurgence of previously reinforced problem behavior and reduced appropriate requests, but FT reinforcer delivery following DRA mitigated resurgence of problem behavior and maintained appropriate requests.
通过非依随反应的强化物给予，可以防止在替代行为区别性强化（DRA）停止后问题行为的复发。在基础研究中，DRA之后的非依随反应强化物给予可防止最初被强化反应的复发，并维持替代反应（利文 & 拉塔尔，2003年，实验3）。我们通过评估DRA之后定时（FT）强化物给予是否能防止4名残疾儿童问题行为的复发并维持恰当行为，来检验这些结果的普遍性。对于所有参与者，DRA后的消退导致先前被强化的问题行为复发，并减少了恰当请求，但DRA后的FT强化物给予减轻了问题行为的复发，并维持了恰当请求。
