冲动性选择可以定义为暂时偏好较小的奖励（SS）而不是较大的奖励（LL）。双曲贴现意味着，当生物体在一系列SS与LL之间同时选择时，冲动选择的发生率要低于在单个SS与LL之间选择时。8只大鼠暴露于两种条件的跨时选择范式，使用蔗糖溶液作为奖励。在这两种情况下，LL是150穆尔延迟3秒，而SS是一个即时奖励，范围从25-150穆尔跨会话。当选择的奖励连续三次自动交付（捆绑）时，对LL的偏好要大于单独选择并在每次选择后交付的情况。对于8只大鼠中的每一只，估计产生冷漠的SS量在捆绑条件下高于单一条件下。因为捆绑在人类可能是基于一个人的当前选择是未来选择的预测，这里提出的数据可能会证明自我控制的一个重要组成部分。
Impulsive choice can be defined as temporary preference for a smaller-sooner reward (SS) over a larger-later reward (LL). Hyperbolic discounting implies that impulsive choices will occur less when organisms choose between a series of SSs versus LLs all at once than when they choose between single SS versus LL pairs. Eight rats were exposed to two conditions of an intertemporal choice paradigm using sucrose solution as reward. In both conditions, the LL was 150 mul delayed by 3 s, while the SS was an immediate reward that ranged from 25-150 mul across sessions. Preference for the LL was greater when the chosen reward was automatically delivered three times in succession (bundled) than when it was chosen singly and delivered after each choice. For each of the 8 rats, the estimated SS amount that produced indifference was higher in the bundled condition than in the single condition. Because bundling in humans may be based on the perception that one's current choice is predictive of future choices, the data presented here may demonstrate an important building block of self-control.
