The past 30 years have witnessed a continued and growing interest in the production and comprehension of manual pointing gestures in nonhuman animals. Captive primates with diverse rearing histories have shown evidence of both pointing production and comprehension, though there certainly are individual and species differences, as well as substantive critiques of how to interpret pointing or "pointing-like" gestures in animals. Early literature primarily addressed basic questions about whether captive apes point, understand pointing, and use the gesture in a way that communicates intent (declarative) rather than motivational states (imperative). Interest in these questions continues, but more recently there has been a dramatic increase in the number of articles examining pointing in a diverse array of species, with an especially large literature on canids. This proliferation of research on pointing and the diversification of species studied has brought new and exciting questions about the evolution of social cognition, and the effects of rearing history and domestication on pointing production and, more prolifically, comprehension. A review of this work is in order. In this article, we examine trends in the literature on pointing in nonhumans. Specifically, we examine publication frequencies of different study species from 1987 to 2016. We also review data on the form and function of pointing, and evidence either supporting or refuting the conclusion that various nonhuman species comprehend the meaning of pointing gestures.

在过去30年里，人们对非人类动物手动指示性手势的产生和理解的兴趣持续增长。具有不同饲养历史的圈养灵长类动物已表现出指示性手势产生和理解的证据，尽管在如何解释动物的指示性或“类指示性”手势方面，确实存在个体和物种差异以及大量批评意见。早期文献主要探讨一些基本问题，比如圈养猿类是否会指示、理解指示，并以传达意图（陈述性）而非动机状态（祈使性）的方式使用这种手势。对这些问题的兴趣依然存在，但最近，研究各种物种指示性手势的文章数量急剧增加，关于犬科动物的文献尤其丰富。指示性手势研究的大量涌现以及所研究物种的多样化，带来了关于社会认知进化以及饲养历史和驯化对指示性手势产生（更多的是对理解）的影响等新的、令人兴奋的问题。有必要对这项工作进行综述。在本文中，我们研究了关于非人类动物指示性手势的文献趋势。具体而言，我们考察了1987年至2016年不同研究物种的发表频率。我们还综述了有关指示性手势形式和功能的数据，以及支持或反驳各种非人类物种理解指示性手势含义这一结论的证据。（PsycINFO数据库记录）
