当识别其他个体时，动物可以将当前提示与来自相同感觉模态的关于该个体的存储信息相匹配。动物也可以将联合收割机当前的信息与先前从其他感觉模态获得的信息相结合，这表明它们拥有独立于模态的个体的复杂认知模板。我们调查了山羊（山羊）是否具有跨模态表示（视觉）的同种。我们向受试者提供了两个人之间等距广播的记录同种呼叫，其中一个是呼叫者。我们发现，当与一个stablemate和另一个牛群成员，山羊看向呼叫者更快，更长的时间比非呼叫者，无论呼叫者的身份。相比之下，当选择两个牛群成员，除了他们的stablemate，山羊没有表现出偏好看向呼叫者。山羊对亲密的社会伙伴表现出跨模态识别，但对不太熟悉的羊群成员却没有。山羊在识别同种时可能会采用推理推理，这可能有助于基于不完整信息的个体识别。了解跨模态识别的流行程度以及不同感觉模态的整合程度，可以深入了解动物如何学习其他个体以及动物交流的进化。
When identifying other individuals, animals may match current cues with stored information about that individual from the same sensory modality. Animals may also be able to combine current information with previously acquired information from other sensory modalities, indicating that they possess complex cognitive templates of individuals that are independent of modality. We investigated whether goats (Capra hircus) possess cross-modal representations (auditory–visual) of conspecifics. We presented subjects with recorded conspecific calls broadcast equidistant between two individuals, one of which was the caller. We found that, when presented with a stablemate and another herd member, goats looked towards the caller sooner and for longer than the non-caller, regardless of caller identity. By contrast, when choosing between two herd members, other than their stablemate, goats did not show a preference to look towards the caller. Goats show cross-modal recognition of close social partners, but not of less familiar herd members. Goats may employ inferential reasoning when identifying conspecifics, potentially facilitating individual identification based on incomplete information. Understanding the prevalence of cross-modal recognition and the degree to which different sensory modalities are integrated provides insight into how animals learn about other individuals, and the evolution of animal communication.
