1990年5月至1993年5月，在哥斯达黎加的洛马斯巴尔布达尔对野生白脸卷尾猴的社会关系进行研究期间，雄性首领被一只从属的雄性首领废黜。排名逆转之前，下降的接近维护由女性的阿尔法男性，和增加，在一定量的侵略直接向阿尔法男性的贝塔女性和她的女性联盟的合作伙伴。在排名逆转的时候，女性从给thegargle发声专门给旧的阿尔法男性漱口新的阿尔法男性;然而，青少年不太一致，关于他们漱口的男性。在排名逆转的时候，大多数成年女性减少了与旧的阿尔法男性接近和梳理的时间，并增加了与新的阿尔法男性接近和梳理的时间。相反，青少年与男性的关系模式在逆转后并没有以可预测的方式发生变化。卷尾猴在这一排名逆转的社会策略相比，黑猩猩。
During the course of a study of social relationships in wild, white-faced capuchins at Lomas Barbudal, Costa Rice (May 1990–May 1993), the alpha male was deposed by a subordinate male. The rank reversal was preceded by a decline in proximity maintenance by females to the alpha male, and an increase, in the amount of aggression directed toward the alpha male by the beta female and her female coalition partners. At the time of the rank reversal, females switched from giving thegargle vocalization exclusively to the old alpha male to gargling to the new alpha male; however, juveniles were less consistent with regard to which male they gargled to. At the time of the rank reversal, most adult females reduced the time spent in proximity and grooming with the old alpha male, and increased the time spent in proximity and grooming with the new alpha male. In contrast, juveniles' patterns of affiliation with males did not change in a predictable way following the reversal. The social strategies employed by capuchin monkeys during this rank reversal are compared with those of chimpanzees.
