In Experiment 1a, rats trained to escape shock by performing a 2-s inactive response were less impaired on a subsequent 2-way shuttle response than their yoked counterparts that received inescapable shock. In contrast, in Experiment 1b, rats trained to escape shock by performing a longer duration inactive response were more impaired on the subsequent escape task than their inescapably shocked counterparts. In Experiment 2, the results of Experiments 1a and 1b were replicated, and the inactive responses performed during pretreatment by both the escapable and inescapable shock groups were assessed and correlated with test stage 2-way shuttle escape performance. These activity data indicate that inactivity during pretreatment shock in both escapable and inescapable shock groups was a highly reliable predictor of subsequent 2-way shuttle performance, irrespective of the pretreatment shock contingency to which these Ss were exposed.
在实验1a中，经训练通过做出2秒静止反应来逃避电击的大鼠，在随后的双向穿梭反应中，比接受不可逃避电击的配对对照大鼠受损程度要小。相比之下，在实验1b中，经训练通过做出更长时间静止反应来逃避电击的大鼠，在随后的逃避任务中，比接受不可逃避电击的对照大鼠受损程度更大。在实验2中，重复了实验1a和1b的结果，并对可逃避电击组和不可逃避电击组在预处理期间做出的静止反应进行了评估，并将其与测试阶段的双向穿梭逃避表现进行关联。这些活动数据表明，可逃避电击组和不可逃避电击组在预处理电击期间的静止状态，是随后双向穿梭表现的一个高度可靠的预测指标，而与这些受试动物所接受的预处理电击条件无关。
