The efficacy of three different schedules of reinforcement for promoting and sustaining drug abstinence was compared in this study. Cigarette smoking was studied as an exemplar of stimulant drug self-administration. Sixty cigarette smokers were assigned to one of three groups (progressive rate of reinforcement, fixed rate of reinforcement, and yoked control). Participants in all three groups were asked to refrain from smoking for 1 week. Participants in the progressive and fixed groups achieved greater mean levels of abstinence than those in the control group. Participants in the progressive group were significantly less likely to resume smoking when they became abstinent than participants in the other groups.
本研究比较了三种不同强化时间表在促进和维持戒毒方面的效果。以吸烟作为刺激性药物自我给药的一个范例进行研究。60名吸烟者被分配到三组之一(渐进强化率组、固定强化率组和匹配对照组)。所有三组的参与者都被要求戒烟1周。渐进组和固定组的参与者比对照组的参与者实现了更高的平均戒烟水平。与其他组的参与者相比,渐进组的参与者在戒烟后复吸的可能性显著更低。
