为了确定依赖吸烟者通过应急管理减少吸烟是否会比不减少吸烟的吸烟者减少延迟强化物的折扣，中度到重度吸烟者被随机分配到两种情况之一。应急管理条件和控制条件。在三个阶段（假设货币和香烟的基线折扣确定，应急管理或控制条件的实施，以及干预后折扣确定）中，加强减少吸烟的程序在所有暴露于该程序的受试者中产生的CO减少。在加强减少吸烟的小组中，香烟和金钱的折扣都显著下降，而对照组对这两种商品的折扣都没有明显变化。吸烟的减少可以导致折扣的减少，而当前吸烟者的折扣增加可能是尼古丁依赖的可逆效应。
To determine whether reduction of smoking via contingency management in dependent smokers would decrease the discounting of delayed reinforcers compared with smokers who did not reduce their smoking, moderate to heavy cigarette smokers were randomly assigned to one of two conditions. a contingency management condition and a control condition. In three phases (baseline discounting determination for hypothetical money and cigarettes, implementation of a contingency management or control condition, and postintervention discounting determination), the procedure to reinforce reduction in cigarette smoking produced CO decreases in all subjects exposed to that procedure. Discounting decreased significantly for both cigarettes and money among the group for whom smoking reductions were reinforced, whereas the control group showed no significant change for either commodity. Reductions in smoking can lead to reductions in discounting, and increased discounting in current smokers may be a reversible effect of nicotine dependence.
