延迟贴现是指报酬的现值因延迟收到而下降。在各种物种、种群和奖励类型中，价值会随着延迟而呈双曲线下降。延迟时间越短，价值下降越剧烈，延迟时间越长，价值下降越平缓。定量建模提供了精确的措施来表征贴现函数的形式。这些措施可以被视为高阶因变量，干预变量，或假设的结构。我认为延迟折扣的程度可能是一种个性特征。最后，延迟折扣措施的本体论地位是无关紧要的。无论延迟折扣是什么，它的研究为行为分析和其他领域的测量提供了强大的通用性和预测有效性，用于各种重要的人类问题。研究降低延迟折扣的程度有可能产生巨大的社会效益。
Delay discounting is the decline in the present value of a reward with delay to its receipt. Across a variety of species, populations, and reward types, value declines hyperbolically with delay. Value declines steeply with shorter delays, but more shallowly with longer delays. Quantitative modeling provides precise measures to characterize the form of the discount function. These measures may be regarded as higher-order dependent variables, intervening variables, or hypothetical constructs. I suggest the degree of delay discounting may be a personality trait. In the end, the ontological status of measures of delay discounting is irrelevant. Whatever delay discounting may be, its study has provided the field of behavior analysis and other areas measures with robust generality and predictive validity for a variety of significant human problems. Research on moderating the degree of delay discounting has the potential to produce substantial societal benefits.
