Stressful experiences can be transmitted among individuals through social interactions. Like humans, rodents are social creatures whose behavior and physiology can be influenced by the emotional state of fellow rodents. This paper will review rodent studies which have explored two conditions of potential social stress contagion using the social defeat paradigm. In the vicarious social defeat model, mice and rats that witness a conspecific being socially defeated exhibit physiological stress responses and develop a host of depressive- and anxiety-like behavioral deficits. Likewise, social interaction with a stressed partner in the aftermath of social defeat stress results in physiological stress responses and social avoidance behavior. After summarizing the existing literature on this newly emerging area of social defeat stress contagion in rodents, we will discuss the potential utility of these rodent models for investigating the neurobiological processes and sensory channels of information that allow for the spread of psychophysiological effects of stress across individuals.

社会失败压力的蔓延：啮齿动物研究的见解。

压力经历可以通过社交互动在个体之间传递。像人类一样，啮齿动物是社交动物，其行为和生理可能会受到其他啮齿动物情绪状态的影响。本文将回顾啮齿动物的研究，该研究利用社会失败范例探讨了潜在的社会压力传染的两个条件。在替代性社会挫败模型中，目击者已被社会挫败，小鼠和大鼠表现出生理应激反应，并出现了许多抑郁和焦虑样的行为缺陷。同样，在社交挫败压力后与压力重重的伴侣进行社交互动也会导致生理压力反应和社交回避行为。在总结了有关啮齿动物这一新出现的社会失败应激传染领域的文献之后，
