Zahavi's “Bond Testing Hypothesis” states that irritating stimuli are used to elicit honest information from social partners regarding their attitudes towards the relationship. Two elements of the Cebus capucinus vocal repertoire, the “gargle” and “twargle,” have been hypothesized to serve such a bond-testing function. The greatest threat to C. capucinus infant survival, and to adult female reproductive success, is infanticide perpetrated by alpha males. Thus, we predicted that infants (<8 months), pregnant females and females with infants would gargle/twargle at higher rates than the rest of the population, directing these vocalizations primarily to the alpha male. Over 16 years, researchers collected data via focal follows in 11 habituated groups of wild capuchins in Lomas Barbudal, Costa Rica. We found some support for our hypothesis. Infants and females with infants (<8 months) vocalized at higher rates than the rest of the population. Pregnant females did not vocalize at relatively high rates. Infants (age 8–23 months) were the only target group that vocalized more when the alpha male was not their father. Monkeys gargled and twargled most frequently towards the alpha male, who is both the perpetrator of infanticide and the most effective protector against potentially infanticidal males.

白面卷尾猴（Cebus capucinus）“Gargle and Twargle”发声率的人口统计学相关性是否与杀婴风险评估假设一致？

Zahavi 的“债券测试假设”指出，刺激性刺激被用来从社会伙伴那里获得关于他们对关系的态度的诚实信息。Cebus capucinus声乐曲目的两个元素，“漱口”和“twargle”，已被假设用于提供这种结合测试功能。对C. capucinus的最大威胁婴儿的生存，以及成年女性的生殖成功，都是由阿尔法男性实施的杀婴行为。因此，我们预测婴儿（<8 个月）、怀孕的女性和有婴儿的女性会以比其他人群更高的速率漱口/扭动，将这些发声主要指向阿尔法男性。16 年来，研究人员通过焦点追踪收集了哥斯达黎加洛马斯巴布达尔 11 个习惯性野生卷尾猴群体的数据。我们为我们的假设找到了一些支持。婴儿和有婴儿（<8 个月）的女性发声率高于其他人群。怀孕的女性没有以相对较高的频率发声。当阿尔法男性不是他们的父亲时，婴儿（8-23 个月大）是唯一发声更多的目标群体。猴子最频繁地向阿尔法男性漱口和吐痰，
