论文摘要
特定的认知过程在跨颞下选择中不断打折的偏差中的作用尚不清楚。我们评估了在长期表示的折现率和非线性方面的跨期选择任务中的不耐烦。预计非线性时间表示会解释折现率的不一致。参与者执行了时间幅度估计和跨期选择任务。通过拟合线性和功率功能来估计时间间隔的心理物理功能，而折现功能是通过拟合指数和双曲线功能估算的。 65％参与者的时间幅度估计值与功率函数更好（主要是压缩）。 63％的参与者具有跨期的选择模式，最适合双曲线功能。即使在折现率计算中补偿了时间幅度估计中的感知偏差，14个参与者中有8个的数据仍会表现出时间不一致。结果表明，折现率的时间不一致可以通过时间表示的偏见来在不同程度上解释。时间表示和折现率中的非线性应分为单独评估。关键字：跨期选择，时间幅度，模型比较，不耐烦，时间不一致
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
