延迟折扣描述了奖励作为延迟接收的函数而失去价值的过程;奖励失去价值的速度被称为延迟折扣率。延迟折扣率是许多具有社会重要性的行为的可靠预测指标。获得人类受试者延迟折扣率的一种有效方法是通过21项和27项货币选择量表，这是一种简短的二分选择任务，用于评估小的即时和较大的延迟货币结果之间的偏好。不幸的是，货币选择量表的评分程序相当复杂，这可能会成为其使用的障碍。本报告详细介绍了一个免费提供的基于Excel的电子表格工具，该工具使用传统和现代/先进的方法自动对货币选择问卷的回答集进行评分。本文概述了货币选择问卷及其评分算法。最后，我们总结了使用电子表格工具的一般注意事项。
Delay discounting describes the process wherein rewards lose value as a function of their delayed receipt; how quickly rewards lose value is termed the rate of delay discounting. Rates of delay discounting are robust predictors of much behavior of societal importance. One efficient approach to obtaining a human subject's rate of delay discounting is via the 21- and 27-item Monetary Choice Questionnaires, brief dichotomous choice tasks that assess preference between small immediate and larger delayed monetary outcomes. Unfortunately, the scoring procedures for the Monetary Choice Questionnaires are rather complex, which may serve as a barrier to their use. This report details a freely available Excel-based spreadsheet tool that automatically scores Monetary Choice Questionnaire response sets, using both traditional and contemporary/advanced approaches. An overview of the Monetary Choice Questionnaire and its scoring algorithm is provided. We conclude with general considerations for using the spreadsheet tool.
