情绪调节对于应对压力源至关重要，但反过来也会受到压力的影响。最初的研究提供了混合的证据表明，无论是有益的或有害的压力对认知情绪调节的影响，这取决于压力的时间，性别或监管策略。在这里，我们调查了急性压力对男性和女性不同情绪调节策略的影响。N = 118名健康参与者进行了特里尔社会压力测试或控制条件后，他们完成了情绪调节范式，要求他们调节自己的情绪，以应对负面图片使用重新评价或分心。反复测量皮质醇水平以量化HPA轴活性的变化。情感评级和瞳孔扩张用于测量情绪调节成功率和调节情绪的认知努力。压力降低了男性的觉醒，增加了重新评价的效价和成功率，而在女性中没有发现显着的压力效应。此外，强调男性在重新评估过程中瞳孔直径显着扩大，这表明增强了认知调节参与，最终可能导致更好的情绪调节结果。皮质醇分泌与男性主观重新评价的成功呈正相关，这表明糖皮质激素驱动的机制可能会促进压力后的情绪调节表现。
Emotion regulation is crucial for coping with stressors but in turn can also be influenced by stress. Initial studies provided mixed evidence showing either beneficial or impairing stress effects on cognitive emotion regulation depending on stress timing, sex or the regulatory strategy. Here, we investigated the impact of acute stress on different emotion regulation strategies in men and women. N = 118 healthy participants were subjected to the Trier Social Stress Test or a control condition after which they completed an emotion regulation paradigm, requiring them to regulate their emotions in response to negative pictures using reappraisal or distraction. Cortisol levels were repeatedly measured to quantify changes in HPA axis activity. Affective ratings and pupil dilation served to measure emotion regulation success and the cognitive effort to regulate emotions. Stress reduced arousal and increased valence and success ratings for reappraisal in men, whereas no significant stress effects were found in women. Moreover, stressed men displayed a significant expansion of pupil diameter during reappraisal suggesting enhanced cognitive regulatory engagement, which ultimately may have led to better emotion regulation outcomes. Cortisol secretion positively correlated with subjective reappraisal success in men, suggesting a glucocorticoid-driven mechanism that may promote emotion regulatory performance in the aftermath of stress.
