We investigated how the acoustic structure of the cotton-top tamarin monkey's (Saguinus oedipus) combination long call relates to the antiphonal calling behavior of conspecifics. Combination long calls can function as contact calls and are produced by socially isolated individuals. Often conspecifics respond to these calls with their own long calls. Structurally, these calls are always composed of one or more 'chirps' followed by two or more 'whistles'. We compared the antiphonal calling responses to playbacks of complete, naturally produced long calls versus single whistles or single chirps. Subjects responded significantly more to whole calls than to either syllable-type alone. Thus, our data suggest that, in terms of the antiphonal calling behavior of socially isolated conspecifics, the whole long call is the unit of perception.
我们研究了棉顶狨猴（Saguinus oedipus）的组合长叫声的声学结构如何与同种个体的对答鸣叫行为相关。组合长叫声可作为联络叫声，由社会隔离的个体发出。同种个体常常会用自己的长叫声回应这些叫声。从结构上看，这些叫声总是由一个或多个“啁啾声”后跟两个或更多“口哨声”组成。我们比较了对完整的、自然发出的长叫声回放与单个口哨声或单个啁啾声回放的对答鸣叫反应。与单独的任何一种音节类型相比，实验对象对完整叫声的反应明显更多。因此，我们的数据表明，就社会隔离的同种个体的对答鸣叫行为而言，整个长叫声是感知单元。
