The current study analyzed the effects of three frames of reward magnitude—quantity, volume, and duration—on the rate at which college students discounted hypothetical, delayed monetary rewards. Hypothetical scenarios were presented using the fill‐in‐the‐blank discounting questionnaire and participants made choices between immediate and delayed hypothetical monetary rewards. Scenarios framed the monetary choices as (a) quantity of dollar bills, (b) height (inches) of a stack of dollar bills, and (c) duration of time spent in a hypothetical cash machine to collect dollar bills. For each scenario, participants' subjective values were used to calculate the area under the curve (AuC). Framing resulted in a moderate effect size: The duration frame yielded significantly smaller AuC values compared to the quantity and volume frames. Thus, the framing of reward magnitude was a significant variable in controlling discounting rates for hypothetical, delayed monetary rewards. Subsequent investigations should be aware of the independent effects of the reward magnitude frames on delay discounting rates.

在假设的货币情景中，奖励幅度框架对延迟贴现度量的影响。

当前的研究分析了奖励幅度的三个框架——数量、数量和持续时间——对大学生打折假设的、延迟的金钱奖励的比率的影响。使用填空式折扣问卷呈现假设情景，参与者在即时和延迟假设货币奖励之间做出选择。情景将货币选择框定为 (a) 美元钞票的数量，(b) 一叠美元钞票的高度（英寸），以及 (c) 在假设的自动取款机中收集美元钞票的时间。对于每个场景，参与者的主观值用于计算曲线下面积 (AuC)。取景产生适度的效果大小：与数量和体积框架相比，持续时间框架产生的 AuC 值要小得多。因此，奖励幅度的框架是控制假设的、延迟的货币奖励的贴现率的一个重要变量。随后的调查应该了解奖励幅度框架对延迟贴现率的独立影响。
