We describe a novel approach to the measurement of discounting based on calculating the area under the empirical discounting function. This approach avoids some of the problems associated with measures based on estimates of the parameters of theoretical discounting functions. The area measure may be easily calculated for both individual and group data collected using any of a variety of current delay and probability discounting procedures. The present approach is not intended as a substitute for theoretical discounting models. It is useful, however, to have a simple, univariate measure of discounting that is not tied to any specific theoretical framework.
我们描述了一种基于计算经验性折扣函数下的面积来测量折扣的新方法。这种方法避免了与基于理论折扣函数参数估计的测量方法相关的一些问题。对于使用各种当前延迟和概率折扣程序收集的个体和群体数据，面积测量都可以轻松计算。本方法并非旨在替代理论折扣模型。然而，拥有一种简单的、与任何特定理论框架无关的单变量折扣测量方法是很有用的。
