People vary in their responses to stress. The present study aimed to investigate whether and how alpha frontal asymmetry (AFA) measured in the resting state underlies the individual differences in psychological responses to acute psychosocial stress (e.g., increases in heart rate and cortisol) induced by the Trier social stress test. Forty-three healthy male adults were enrolled in this study. The results showed that the AFA score negatively predicted both heart rate and cortisol responses, that is relatively higher right-frontal activity during the resting state was related to a stronger physiological stress response. These results indicated that higher withdrawal motivation or effortful control is associated with a higher physiological stress response, which suggested that AFA in the resting state can serve as a biological predictor of acute stress responses in men.

阿尔法额叶不对称是男性对急性社会心理压力反应的个体差异的基础

人们对压力的反应各不相同。本研究旨在调查在静息状态下测量的 α 额叶不对称性 (AFA) 是否以及如何构成对 Trier 社会压力测试引起的急性社会心理压力（例如，心率和皮质醇增加）的心理反应的个体差异的基础。43 名健康男性成年人参加了这项研究。结果表明，AFA 评分对心率和皮质醇反应都有负面预测，即静息状态下相对较高的右额叶活动与更强的生理应激反应有关。这些结果表明，较高的戒断动机或努力控制与较高的生理应激反应有关，
