Mourning constitutes an important human emotion, which might cause—among other things—major depressive symptoms when lasting for too long. To date, no study investigated whether mourning is related to specific psychophysiological activation patterns. Therefore, we examined physiological reactions induced by iconographic mourning-related stimuli in comparison to neutral and attachment stimuli in healthy adults (N = 77, mean age: 21.9). We evaluated pupillometric and eye-tracking parameters as well as heart rate variability (HRV) and skin conductance (EDA). Eye-tracking revealed a stronger dilated pupil during mourning in comparison to the neutral, but not to the attachment condition; furthermore, fixation patterns revealed less fixations on mourning stimuli. While HF HRV was reduced during mourning and attachment, we found no differences concerning EDA parameters between conditions. Results suggest specific eye-movement and pupil adaptations during representations of mourning, which might point toward inward cognition or avoidance, but no specific physiological pattern concerning HRV and EDA.

哀悼的心理生理学调查:故事有两个方面

哀悼是一种重要的人类情感,如果持续时间过长,可能会导致——除其他外——严重的抑郁症状。迄今为止,没有研究调查哀悼是否与特定的心理生理激活模式有关。因此,我们检查了由图像哀悼相关刺激引起的生理反应,与健康成人的中性和依恋刺激相比(N = 77,平均年龄:21.9)。我们评估了瞳孔测量和眼动追踪参数以及心率变异性 (HRV) 和皮肤电导 (EDA)。眼动追踪显示,与中性相比,在哀悼期间瞳孔放大更强,但与依恋状态相比则不然;此外,固定模式显示对哀悼刺激的固定较少。虽然在哀悼和依恋期间 HF HRV 降低,我们发现条件之间的 EDA 参数没有差异。结果表明,在表达哀悼期间,特定的眼球运动和瞳孔适应,这可能指向内向认知或回避,但没有关于 HRV 和 EDA 的特定生理模式。
