基于情绪传染机制，庆祝和集体欢乐的爆发可以在人类社区中自发发生。在动物中，当它们团聚或期待奖励时，已经报道了一些类似的集体兴奋的例子，但对这些多重相互作用的过程和意义知之甚少。我们的实验研究了这样的集体觉醒在两个圈养组的通肯猕猴（Macaca tonkeana）的背景下，团聚后的两个分组的临时分离。我们比较了2和48小时的分离期后的个人的行为与控制期没有分离。这项研究表明，可以重复地诱导友好互动的爆发，其中小组成员在几分钟内跑来跑去，互相拥抱和抓住，同时展示许多亲和的声音和面部表情。分离时间越长，亲和互动的比率越高，持续时间越长。个体更频繁地与来自先前分离的亚组的群体成员联系，而不是与那些留在自己的亚组中的人联系。集体觉醒之后是一个安静的时期，其特征是高比例的接触坐和社会梳理。这些结果指出了集体唤醒在社会凝聚力中的作用，它们可以解决社会紧张局势，更新社会关系。我们认为，通肯猕猴在这些事件中所经历的情绪状态代表了一种类似于我们人类所说的“分享快乐”的倾向。"
Celebrations and bursts of communal joy can occur spontaneously in human communities based on mechanisms of emotional contagion. Some examples of similar collective excitement have been reported in animals when they reunite or anticipate rewards, but little is known about the processes and meaning of these multiple interactions. We experimentally studied such collective arousals in two captive groups of Tonkean macaques (Macaca tonkeana) within the context of reunions following the temporary separation of two subgroups. We compared the behaviors of individuals after separation periods of 2 and 48 h with a control period with no separation. This study showed that it is possible to reproducibly induce bursts of friendly interactions in which groupmates run around over a period of several minutes, embracing and grasping one another while displaying numerous affiliative vocalizations and facial expressions. The longer the period of separation, the higher and longer-lasting the rates of affiliative interactions were. Individuals affiliated more frequently with groupmates from a previously separated subgroup than with those having stayed in their own subgroup. Collective arousal was followed by a quieter period characterized by high rates of contact-sitting and social grooming. These results point at the role of collective arousals in social cohesion; they could resolve social tension and renew social relationships. We propose that the emotional state experienced by Tonkean macaques during such events represents a disposition similar to that giving rise to what we humans call "shared joy."
