Abstract

Acute stress can impair human working memory. Little is known, however, about the effects of acute stress on working memory strategies. The goal of this research was to investigate the effects of acute stress on use of a systematic spatial working memory search strategy. Participants (28 females and 20 males per group) completed the Trier Social Stress Test (TSST) or control tasks. Use of a systematic spatial working memory search strategy was measured through performance on the spatial working memory subtest of the Cambridge Neuropsychological Test Automated Battery (CANTAB). The TSST was effective at producing subjective and cortisol stress responses, but there was no significant stress effect on use of a systematic search strategy or working memory search errors. There were also no significant relationships between subjective and cortisol stress responses and use of a systematic search strategy or working memory search errors within the stress group. These results suggest that acute stress does not impair the self-generation or execution of a systematic spatial working memory search strategy.

急性应激与人类空间工作记忆策略的使用。

急性压力会损害人的工作记忆。然而，关于急性压力对工作记忆策略的影响，我们所知甚少。本研究的目的是探讨急性应激对系统空间工作记忆搜索策略的影响。参与者(每组28名女性和20名男性)完成了特里尔社会压力测试(TSST)或对照任务。通过剑桥神经心理测试自动化单元(CANTAB)的空间工作记忆子测试的表现来衡量系统空间工作记忆搜索策略的使用。TSST在产生主观和皮质醇应激反应方面是有效的，但在使用系统搜索策略和工作记忆搜索错误方面没有显著的应激影响。在压力组中，主观和皮质醇应激反应与使用系统搜索策略或工作记忆搜索错误之间也没有显著的关系。这些结果表明，急性应激不会损害自我产生或执行系统的空间工作记忆搜索策略。

期刊介绍： The journal Stress aims to provide scientists involved in stress research with the possibility of reading a more integrated view of the field. Peer reviewed papers, invited reviews and short communications will deal with interdisciplinary aspects of stress in terms of: the mechanisms of stressful stimulation, including within and between individuals; the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, coping strategies and the pathological consequences of stress. Stress will publish the latest developments in physiology, neurobiology, molecular biology, genetics research, immunology, and behavioural studies as they impact on the understanding of stress and its adverse consequences and their amelioration. Specific approaches may include transgenic/knockout animals, developmental/programming studies, electrophysiology, histochemistry, neurochemistry, neuropharmacology, neuroanatomy, neuroimaging, endocrinology, autonomic physiology, immunology, chronic pain, ethological and other behavioural studies and clinical measures.
