已显示压力会损害决策。然而，这种现象的时间发展仍然知之甚少。我们推测，快速压力诱导了去甲肾上腺素的增加，皮质醇的延迟增加可能会对受风险的决策产生相反的影响。因此，三个不同的实验组进行了Trier社会压力测试（TSST），并在与压力源有关的不同时间点上执行了骰子任务（GDT），该时间点持续了大约18分钟。第一组在应力发作后5分钟进行了GDT，第二组和第三组在TSST发作后进行了18或28分钟。对照组的决策绩效是在相应的休息时间后测量的。结果证实了交感神经系统的快速激活，下丘脑垂体肾上腺轴的反应较慢。在GDT中，与对照组相比，5分钟和18分钟的压力组的决策绩效改善，并发生了28分钟的压力组。描述地，压力小组之后的28分钟的决策比对照组的决策更具风险。我们的发现符合以下想法：儿茶酚胺的适度增加会增强决策性能，而升高的皮质醇浓度可能会通过快速的非原始机制对决策产生负面影响。 （c）2013 Elsevier B.V.保留所有权利。
Stress has been shown to impair decision making. However the temporal development of this phenomenon remains poorly understood. We speculated that the rapid stress induced increase in norepinephrine and the delayed increase in cortisol might exert opposing effects on decision making under risk. Therefore, three different experimental groups underwent the Trier Social Stress Test (TSST) and performed the Game of Dice Task (GDT) at different time points in relation to the stressor, which lasted approximately 18 min. The first group performed the GDT 5 min after stress onset, the second and third group performed the GDT either 18 or 28 min after TSST onset. Decision-making performance of the control group was measured after a respective resting time. Results confirmed a rapid activation of the sympathetic nervous system and a somewhat slower response of the hypothalamic pituitary adrenal axis. In the GDT an improvement of decision-making performance in the 5 and 18 min stress groups compared to controls and the 28 min stress group occurred. Descriptively, decision making of the 28 min after stress group was more risky than decision making of the control group. Our findings are in line with the idea that a moderate increase in catecholamines enhances decision-making performance, while elevated cortisol concentrations may negatively affect decision making presumably via rapid nongenomic mechanisms.
