先前暴露于不可避免的休克已被报道干扰选择逃避学习，但一些研究人员未能获得这种效果。一系列的五个实验研究的条件下，选择逃避学习在自动Y-迷宫中受损的预处理与不可避免的冲击。不可避免的休克大鼠作出更多的错误和反应更慢，只有当休克终止延迟和任务无关的线索，目前在选择逃避训练。这些研究结果进行了讨论，在信息处理和神经化学后果暴露于不可避免的休克。
Prior exposure to inescapable shock has been reported to interfere with choice-escape learning, but several investigators have failed to obtain this effect. A series of five experiments examined the conditions under which choice-escape learning in an automated Y-maze is impaired by pretreatment with inescapable shock. Inescapably shocked rats made more errors and responded more slowly than did controls only when shock termination was delayed and task-irrelevant cues were present during choice-escape training. These findings are discussed in terms of information processing and neurochemical consequences of exposure to inescapable shock.
