在成年雄性Wistar大鼠中研究了社会伙伴的压力状态与社会缓冲效应之间的关系。恐惧条件化的大鼠被暴露在相同的背景下，沿着的是一个震惊或非震惊的同种合作伙伴。监测体温和行为反应的变化，以比较社会缓冲的影响，并免疫组化染色室旁核中的Fos蛋白。存在的合作伙伴大鼠衰减应激诱导的体温过高，以及行为反应和Fos表达在应对可怕的情况下，和nonshocked合作伙伴比休克的合作伙伴更有效。这些研究结果表明，社会缓冲效应取决于伴随同种动物的压力状态。
The relationship between a social partner's stress status and the social buffering effect was examined in adult male Wistar rats. Fear-conditioned rats were exposed to the same context along with either a shocked or nonshocked conspecific partner. Changes in body temperature and behavioral responses were monitored in order to compare the effects of social buffering, and the Fos protein in the paraventricular nucleus was immunostained. The presence of the partner rat attenuated stress-induced hyperthermia, as well as behavioral responses and Fos expression in response to the fearful context, and nonshocked partners were more effective than shocked partners. These findings suggest that the social buffering effect depends on the stress status of the accompanying conspecific animal.
