病理性赌徒延迟奖励的折扣与匹配的对照非赌博参与者延迟奖励的折扣进行了比较。所有参与者都完成了一个假设的选择任务，在这个任务中，他们在延迟后可用的1,000美元和立即可用的相等或更少的钱之间重复选择。大量资金的延迟在不同条件下从1周到10年不等。在每个延迟条件下，通过改变选择试验中的即时资金数额，确定了即时资金和延迟资金之间的无差异点。对于大多数参与者来说，无差异点在延迟期间单调下降。总的来说，赌徒比对照组的参与者更大幅度地折扣延迟的奖励。
Discounting of delayed rewards by pathological gamblers was compared to discounting of delayed rewards by matched control nongambling participants. All participants completed a hypothetical choice task in which they made repeated choices between $1,000 available after a delay and an equal or lesser amount of money available immediately. The delay to the large amount of money was varied from 1 week to 10 years across conditions. Indifference points between immediate money and delayed money were identified at each delay condition by varying the amount of immediate money across choice trials. For the majority of participants, indifference points decreased monotonically across delays. Overall, gamblers discounted the delayed rewards more steeply than did control participants.
