冲动在某种意义上是指，随着时间的推移，回报会随着实现时间的增加而贬值，这与人类的各种负面结果有关，但对其背后的认知机制的了解有限。时间间隔不精确度的变化可能是导致冲动性变化的原因之一。我们使用数值模型来生成关于时间不精确度对冲动性的影响的预测。我们区分固定不精确度(即使在对最短的时间间隔进行计时时也适用的不精确度)和成比例不精确度(不精确度随着时间间隔变长而增加的速率)。该模型预测冲动性应随固定不精确度的增加而增大，但随比例不精确度的增大而减小。我们提供了一组欧洲八哥(Sturnus Common garis，n = 28)的数据，在这些数据中，冲动之前是通过跨期选择范式来衡量的。我们使用三峰时间重现程序在相同的个体中测试了间隔时间的不精确性。我们发现在固定的和成比例的不精确度上都存在可重复的个体差异。正如预测的那样，间隔时间比例不精确度较高的鸟类做出的冲动选择较少，而固定不精确度较大的鸟类倾向于做出更多的冲动选择。文献中关于定时不精确和冲动之间关联方向的相互矛盾的观察，可以通过区分不精确的固定分量和比例分量来澄清。网上版载有补充材料，可在10.1007/s10071-020-01456-2查阅。
Impulsivity, in the sense of the extent rewards are devalued as the time until their realization increases, is linked to various negative outcomes in humans, yet understanding of the cognitive mechanisms underlying it is limited. Variation in the imprecision of interval timing is a possible contributor to variation in impulsivity. We use a numerical model to generate predictions concerning the effect of timing imprecision on impulsivity. We distinguish between fixed imprecision (the imprecision that applies even when timing the very shortest time intervals) and proportional imprecision (the rate at which imprecision increases as the interval becomes longer). The model predicts that impulsivity should increase with increasing fixed imprecision, but decrease with increasing proportional imprecision. We present data from a cohort of European starlings (Sturnus vulgaris, n = 28) in which impulsivity had previously been measured through an intertemporal choice paradigm. We tested interval timing imprecision in the same individuals using a tri-peak temporal reproduction procedure. We found repeatable individual differences in both fixed and proportional imprecision. As predicted, birds with greater proportional imprecision in interval timing made fewer impulsive choices, whilst those with greater fixed imprecision tended to make more. Contradictory observations in the literature regarding the direction of association between timing imprecision and impulsivity might be clarified by distinguishing between fixed and proportional components of imprecision.
