对于药物依赖者来说，在假设的选择任务中，延迟时间的药物滥用比延迟时间的金钱更容易被贴现。这一发现的原因尚不清楚。本研究探讨了药物相对于货币的大幅折扣是否可能与药物作为主要/消费性替代品和货币作为条件/非消费性替代品的功能有关。20名没有自我报告的金钱、酒精或食物问题的成年人参加了研究。他们表明了他们对三种假设结果类型的偏好：延迟与即时金钱，延迟与即时食物，延迟与即时酒精。双曲线衰减模型和曲线下面积分析都表明，货币的贴现率低于酒精或食品，但酒精和食品的贴现率相似。这一发现重复了以前的结果，表明没有药物滥用问题的人显示出酒精的急剧折扣。此外，这一发现表明，酒精可能会被大大低估，作为涉及初级/消费性酒精的一般过程的一部分，不一定是因为它是一种药物。(C)2003 Elsevier B.

For drug-dependent individuals, drugs of abuse that are delayed in time are discounted more steeply than money delayed in time in a hypothetical choice task. The reasons for this finding are not clear. This study examined whether steep discounting of drugs relative to money might be related to the function of drugs as primary/consumable reinforcers and money as a conditioned/non-consumable reinforcer. Twenty adults with no self-reported problems with money, alcohol, or food participated. They indicated their preferences for three hypothetical outcome types: delayed versus immediate money, delayed versus immediate food, and delayed versus immediate alcohol. Both the hyperbolic decay model and area under the curve analysis showed that money was discounted less steeply than alcohol or food, but that alcohol and food were discounted similarly. This finding replicates previous results showing that people without drug abuse problems show steep discounting of alcohol. Furthermore, this finding suggests that alcohol may be steeply discounted as part of a general process involving primary/consumable reinforcers, not necessarily because it is a drug.
