Marital stress is associated with a higher incidence of psychiatric disorders, in particular major depression. One pathway through which marital stress may impact emotional health is by compromising emotion-responding processes. We examined a longitudinal sample of adults (N = 116; 59 males; 39-84 years) to verify how marital stress predicts reactivity to, and recovery from, emotional provocation. Individuals watched positive, neutral, and negative pictures while an objective measure of affective state, corrugator supercilii muscle activity, was recorded continuously. Our results indicate that marital stress is associated with short-lived responses to positive pictures, indexed by a less persistent decrease in corrugator activity after picture offset. Extending beyond the prior focus on negative emotional processes, these results suggest that social stress may impact health by influencing the time course of responding to positive events.
婚姻压力与精神疾病尤其是重度抑郁症的较高发病率相关。婚姻压力可能影响情绪健康的一种途径是通过损害情绪反应过程。我们对成年人（N = 116；59名男性；39 - 84岁）的纵向样本进行了研究，以验证婚姻压力如何预测对情绪刺激的反应性以及从情绪刺激中恢复的情况。参与者观看积极、中性和消极图片，同时持续记录皱眉肌活动这一情感状态的客观指标。我们的结果表明，婚姻压力与对积极图片的短暂反应相关，表现为图片消失后皱眉肌活动持续下降的时间较短。这些结果超越了先前对负面情绪过程的关注，表明社会压力可能通过影响对积极事件的反应时间进程来影响健康。
