试验间隔越短，人类受试者在概率性奖励和近乎确定的金钱奖励之间反复选择时，风险规避程度往往会降低。当选择结果序列聚集成三个时，受试者的风险厌恶程度也低于每个选择结果序列与其相邻序列以相等的试验间隔分开时的风险厌恶程度。这些结果进一步扩展了延迟贴现和概率贴现之间的类比。概率折扣，如延迟折扣，可以通过将折扣值与下一个奖励的预期延迟相关联的双曲函数来描述。 (C) 1994 年学术出版社
Human subjects making repeated choices between probabilistic and near-certain monetary rewards tended to be less risk-averse the shorter the intertrial interval. Subjects were also less risk-averse when the choice-outcome sequences were clustered in threes than when each choice-outcome sequence was separated from its neighbors by equal intertrial intervals. These results further extend the analogy between delay discounting and probability discounting. Probability discounting, like delay discounting, may be described by hyperbolic function relating discounted value to expected delay to the next reward. (C) 1994 Academic Press, Inc.
