Physiological linkage refers to the degree to which peoples' physiological responses change in coordinated ways. Here, we examine whether and how physiological linkage relates to incidents of shared emotion, distinguished by valence. Past research has used an "overall average" approach and characterized how physiological linkage over relatively long time periods (e.g., 10-15 min) reflects psychological and social processes (e.g., marital satisfaction, empathy). Here, we used a "momentary" approach and characterized whether physiological linkage over relatively short time periods (i.e., 15 s) reflects shared positive emotion, shared negative emotion, or both, and whether linkage during shared emotions relates to relational functioning. Married couples (156 dyads) had a 15-min conflict conversation in the laboratory. Using behavioral coding, each second of conversation was classified into 1 of 4 emotion categories: shared positive emotion, shared negative emotion, shared neutral emotion, or unshared emotion. Using a composite of 3 peripheral physiological measures (i.e., heart rate, skin conductance, finger pulse amplitude), we computed momentary in-phase and antiphase linkage to represent coordinated changes in the same or opposite direction, respectively. We found that shared positive emotion was associated with higher in-phase and lower antiphase linkage, relative to the other 3 emotion categories. Greater in-phase physiological linkage during shared positive emotion was also consistently associated with higher-quality interactions and relationships, both concurrently and longitudinally (i.e., 5 to 6 years later). These findings advance our understanding of the nature of physiological linkage, the emotional conditions under which it occurs, and its possible associations with relational functioning.

共享积极和共享消极情绪期间的生理联系。

生理联系是指人们的生理反应以协调方式发生变化的程度。在这里，我们检查生理联系是否以及如何与以价区分的共享情绪事件相关。过去的研究使用了“总体平均”方法，并描述了相对较长时间段（例如，10-15 分钟）内的生理联系如何反映心理和社会过程（例如，婚姻满意度、同理心）。在这里，我们使用了一种“瞬时”方法，并表征了相对较短时间段（即 15 秒）内的生理联系是否反映了共同的积极情绪、共同的消极情绪或两者，以及共同情绪期间的联系是否与关系功能有关。已婚夫妇（156 对）在实验室进行了 15 分钟的冲突对话。使用行为编码，对话的每一秒都被分为 4 种情绪类别中的一种：共享积极情绪、共享消极情绪、共享中性情绪或非共享情绪。使用 3 种外周生理测量（即心率、皮肤电导、手指脉冲幅度）的组合，我们计算了瞬时同相和反相联系，以分别表示相同或相反方向的协调变化。我们发现，相对于其他 3 个情绪类别，共享的积极情绪与较高的同相和较低的反相联系相关。共享积极情绪期间更大的同相生理联系也始终与更高质量的互动和关系相关，无论是同时还是纵向（即 5 到 6 年后）。这些发现促进了我们对生理联系的本质、它发生的情绪条件及其与关系功能的可能关联的理解。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
