在本实验中，我们比较了促进和维持短期戒毒的三种不同的强化方案。出于务实的原因，吸烟被作为自我给药的一个例子进行了研究。研究的三个时间表是固定的戒断强化幅度、逐步增加的戒断强化幅度并重置吸毒意外事件，以及逐步增加的戒断强化幅度但没有重置意外事件。十八名吸烟者以平衡的顺序经历了这三个时间表。每个时间表连续5天（周一至周五）有效，期间根据不同的强化时间表加强禁欲。每种情况下可用的强化总量（金钱）都是相同的。在维持最初的禁欲期方面，重置时间表的渐进幅度比其他两个时间表更有效。这些结果系统地复制和扩展了先前研究的结果，证明了将逐渐增加的强化程度与重置应急方案相结合以维持初始戒毒的时间表的有效性，并证明了重置应急方案对此效果的重要性。 (C) 2000 Elsevier Science Ireland Ltd. 保留所有权利。
In this experiment we compared three different schedules of reinforcement for promoting and sustaining short-term drug abstinence. For pragmatic reasons, cigarette smoking was studied as an exemplar of drug self-administration. The three schedules studied were a fixed magnitude of reinforcement for abstinence, a progressive increase in magnitude of reinforcement for abstinence with a reset contingency for drug use, and a progressive increase in magnitude of reinforcement for abstinence without a reset contingency. Eighteen cigarette smokers experienced the three schedules in a counterbalanced order. Each schedule was in effect for 5 consecutive days (M-F), during which time abstinence was reinforced according to the different schedules of reinforcement. The total amount of reinforcement (money) available was the same during each condition. The progressive magnitude with a reset schedule was more effective than the other two schedules in sustaining an initial period of abstinence. These results systematically replicate and extend those from prior studies demonstrating the efficacy of schedules incorporating a progressively increasing magnitude of reinforcement with a reset contingency for sustaining initial drug abstinence, and demonstrate the importance of the reset contingency to that effect.
