在四个实验中，我们比较了延迟、概率和货币金额对得失主观价值的影响。对于延迟收益，较小的金额比较大的金额折扣更大，而在概率收益中观察到相反的模式。然而，对于延迟损失和概率损失，金额对贴现的影响要小得多，也不太可靠。综上所述，差异幅度效应的模式导致延迟收益的贴现明显大于延迟损失，但仅在较小的金额上，而概率收益的贴现明显大于概率损失，但仅在较大的金额上。尽管相同的双曲线函数描述了个体和群体对延迟和概率收益和损失的贴现，但目前的研究结果表明，贴现积极和消极结果涉及不同的过程。原始数据可从www.psychonon-de.org/Archive下载。
In four experiments, we compared the effects of delay, probability, and monetary amount on the subjective value of gains and losses. For delayed gains, smaller amounts were discounted more steeply than larger amounts, whereas the opposite pattern was observed with probabilistic gains. For both delayed and probabilistic losses, however, amount had much smaller and less reliable effects on discounting. Taken together, the pattern of differential magnitude effects leads to delayed gains' being discounted significantly more steeply than delayed losses, but only at smaller amounts, whereas probabilistic gains are discounted significantly more steeply than probabilistic losses, but only at larger amounts. Even though the same hyperbola-like function described both individual and group discounting of delayed and probabilistic gains and losses, the present findings suggest that different processes are involved in discounting positive and negative outcomes.
