Two experiments studied effects of adaptation to cold water stress upon learning in two aversively motivated (shock) tasks. Experiment 1 found animals previously experiencing cold water stress exhibited more tolerance to shock, having shorter latencies, in an approach-avoidance conflict situation than non-treated controls. In Experiment 2, animals with previous cold water stress experience exhibited longer response latencies than controls in an active-avoidance task. These findings provide evidence that adaptation to a noncontingent stressor can modulate behavioral responses which suggest increased tolerance.
两项实验研究了适应冷水应激对两种厌恶动机（电击）任务学习的影响。实验1发现，与未处理的对照组相比，先前经历过冷水应激的动物在接近-回避冲突情境中对电击表现出更高的耐受性，潜伏期更短。在实验2中，先前有过冷水应激经历的动物在主动回避任务中的反应潜伏期比对照组更长。这些发现提供了证据，表明对非偶然性应激源的适应可以调节行为反应，这表明耐受性增加。
