本文探讨了急性应激对中性词和情绪词记忆的影响。参与者（n=40）暴露于心理社会应激或控制任务，随后进行记忆测试。在应激诱导前后和记忆测试后，测量唾液中的应激激素皮质醇。急性应激对所有记忆都有不同的影响，中性词的回忆受损，而情感词的回忆增强。这些对记忆表现的影响不是由皮质醇介导的。作者得出结论，推测记忆效应和皮质醇水平升高几乎没有意义，因为这种效应可能取决于所学习材料的价态。
This article examined effects of acute stress on memory for neutral and emotional words. participants (n=40) were exposed to either a psychosocial stressor or a control task, followed by a memory test. The stress hormone cortisol was measured in saliva before and after stress induction and after the memory test. Acute stress had a differential effect all memory such that recall of neutral words was impaired, whereas that of emotional words was enhanced. These effects on memory performance were not mediated by cortisol. The authors conclude that it makes little sense to speculate about memory effects and elevated levels of cortisol because such effects might depend on the valence of the material that is learned.
