Only a handful of primate species exhibit the social relationship of pair-bonding. Efficient communication is critical for behavioral coordination within pair-bonds to maintain proximity and respond appropriately to extra-pair individuals, and possibly coordinate infant care. The use of complex signaling across modalities may help individuals improve communicative outcomes. We review many ways that pair-bonded species use signals to communicate and maintain bonds, though little previous research has taken a truly multimodal approach within a single species. We make a call for further investigation into pair-bonded communication using a multimodal approach to better understand how these species use all their senses to build, maintain, and advertise their bonds.

多峰双键维持：综述了双键非人类灵长类动物的跨模态信号。

只有少数的灵长类动物表现出配对的社会关系。高效的沟通对于成对债券中的行为协调，维持亲密关系并适当地应对成对配对的个体，并可能协调婴儿护理至关重要。跨模式使用复杂的信号可以帮助个人改善交流效果。尽管以前很少有研究在单个物种内采用真正的多峰方法，但我们回顾了成对键合物种使用信号来传达和维持联系的多种方式。我们呼吁使用多模式方法进一步研究成对的键合通信，以更好地了解这些物种如何利用其所有感官来建立，维持和宣传其键合。
