Separation and subsequent reintroduction of brown capuchins (Cebus apella) can lead to reunion displays during which individuals will embrace and emit high-pitched, loud vocalizations. These displays were investigated in three male capuchins: two adults and one juvenile. These subjects were part of a larger captive social group held at the Capuchin Laboratory, Hiram College, OH, USA. We hypothesized that males would engage in reunion displays following separation regardless of the order of reintroduction, as evidence of an affiliative bond judged by concurrent social behavior. Sixty separations were conducted as part of weekly husbandry over a period of 13 months. Occurrence of reunion displays between the males was recorded with the initiator also noted. Reunion displays among males were found to occur only between the juvenile and alpha male, and all displays were initiated by the juvenile. Displays were highly influenced by the order of reintroduction. We suggest that reunion displays operate to reaffirm social relationships, particularly during situations of social tension.
将棕色卷尾猴（僧帽猴属）分开然后重新引入，可能会引发团聚展示，在此期间，个体之间会相互拥抱，并发出高音调的响亮叫声。对三只雄性卷尾猴进行了此类展示的研究：两只成年猴和一只幼年猴。这些实验对象是美国俄亥俄州海拉姆学院卷尾猴实验室中一个更大的圈养社会群体的一部分。我们假设，雄性卷尾猴在分开后会进行团聚展示，而不管重新引入的顺序如何，这是由同步社会行为判断的一种亲和关系的证据。在13个月的时间里，作为每周饲养管理的一部分，进行了60次分离。记录雄性之间团聚展示的发生情况，并注明发起者。发现雄性之间的团聚展示仅发生在幼年猴和成年雄猴之间，且所有展示均由幼年猴发起。展示受到重新引入顺序的高度影响。我们认为，团聚展示起到了重申社会关系的作用，特别是在社会紧张的情况下。
