英文摘要：
The role of specific cognitive processes in deviations from constant discounting in intertemporal choice is not well understood. We evaluated decreased impatience in intertemporal choice tasks independent of discounting rate and non-linearity in long-scale time representation; nonlinear time representation was expected to explain inconsistencies in discounting rate. Participants performed temporal magnitude estimation and intertemporal choice tasks. Psychophysical functions for time intervals were estimated by fitting linear and power functions, while discounting functions were estimated by fitting exponential and hyperbolic functions. The temporal magnitude estimates of 65% of the participants were better fit with power functions (mostly compression). 63% of the participants had intertemporal choice patterns corresponding best to hyperbolic functions. Even when the perceptual bias in the temporal magnitude estimations was compensated in the discounting rate computation, the data of 8 out of 14 participants continued exhibiting temporal inconsistency. The results suggest that temporal inconsistency in discounting rate can be explained to different degrees by the bias in temporal representations. Non-linearity in temporal representation and discounting rate should be evaluated on an individual basis. Keywords: Intertemporal choice, temporal magnitude, model comparison, impatience, time inconsistency

中文摘要：
在跨期选择中，特定认知过程在偏离持续折扣中的作用尚不清楚。我们评估了跨时选择任务中不耐烦的减少，与长期时间表征中的贴现率和非线性无关；非线性时间表征有望解释贴现率的不一致性。参与者进行时间量级估计和跨时间选择任务。时间间隔的心理物理函数通过拟合线性函数和幂函数来估计，而折扣函数则通过拟合指数函数和双曲函数来估计。65%受试者的时间震级估计值更符合幂函数（主要是压缩）。63%的参与者的跨期选择模式最符合双曲线函数。即使在贴现率计算中补偿了时间幅度估计中的知觉偏差，14名参与者中有8人的数据仍然表现出时间不一致性。结果表明，贴现率的时间不一致性可以通过时间表征中的偏差得到不同程度的解释。时间代表性和贴现率的非线性应单独评估。关键词：跨期选择、时间幅度、模型比较、不耐烦、时间不一致
