Interventions exposing rats to delayed-reward contingencies attenuate suboptimal impulsive choices, a preference for a smaller-sooner (SS) over a larger-later (LL) reward. Interventions may potentially improve delay-tolerance, timing of delays, and/or discrimination of reward magnitudes. Generalization from the intervention to impulsive choice under different procedures can provide insights into the processes that underlie the intervention effects. Experiment 1 tested intervention effects on systematic-delay (SYS) and adjusting-delay (ADJ) procedures, predicting that intervention effects would be more effective on the SYS procedure with predictable delays. The ADJ procedure did not benefit significantly from intervention, but the SYS procedure, unexpectedly, showed greater impulsive choices following intervention. Experiment 2 tested whether short (5 s) SS intervention delays may have promoted greater impulsivity in the SYS impulsive choice procedure in Experiment 1. Short SS delays in choice and intervention procedures increased impulsive choices in comparison to longer (10 s) delays. Incongruent SS delays in the intervention/choice procedures resulted in negative intervention effects. The results suggest that short SS delays are detrimental to self-control and that specific temporal information generalizes from the intervention to the SYS choice task, but not the ADJ choice task.

将大鼠暴露于延迟奖励意外事件的干预措施减弱了次优的冲动选择，即对较小的较早 (SS) 奖励的偏好超过较大的延迟 (LL) 奖励。干预可能会改善延迟容忍度、延迟时间和/或奖励幅度的歧视。从干预到不同程序下的冲动选择的概括可以提供对干预效果背后的过程的洞察。实验 1 测试了对系统延迟 (SYS) 和调整延迟 (ADJ) 程序的干预效果，预测干预效果对具有可预测延迟的 SYS 程序更有效。ADJ 程序并没有从干预中显着受益，但 SYS 程序出乎意料地显示出干预后更大的冲动选择。实验 2 测试了短（5 秒）SS 干预延迟是否可能促进了实验 1 中 SYS 冲动选择过程中更大的冲动性。与较长（10 秒）延迟相比，选择和干预程序中的短 SS 延迟增加了冲动选择。干预/选择程序中不一致的 SS 延迟导致负面干预效果。结果表明，短的 SS 延迟不利于自我控制，并且特定的时间信息从干预推广到 SYS 选择任务，而不是 ADJ 选择任务。干预/选择程序中不一致的 SS 延迟导致负面干预效果。结果表明，短的 SS 延迟不利于自我控制，并且特定的时间信息从干预推广到 SYS 选择任务，而不是 ADJ 选择任务。干预/选择程序中不一致的 SS 延迟导致负面干预效果。结果表明，短的 SS 延迟不利于自我控制，并且特定的时间信息从干预推广到 SYS 选择任务，而不是 ADJ 选择任务。
