指示性手势：来自动物交流系统的证据

指示性手势通常被定义为指明空间中某个物体或处所的手部动作, 但其是否为人类交流系统所独有, 心理学界做了大量研究。通过回顾这一领域的主要理论以及相关争论, 结果发现：动物既可能具有使用指示性手势的能力, 也可以解读手势背后的社会认知意图。未来研究在克服样本数量不一致、实验任务笼统以及研究方法单一等不足的基础上, 还应当注意心理学、语言学以及生物学等多学科的交汇融合。

Pointing Gestures: Evidence from Animal Communication System

Pointing gestures are usually defined as the manual movements pointing to an object or location. Whether Pointing gestures are unique to human communication system is a question of intense psychological research. A comprehensive review of the main theories and related debates suggests that animals may not only have the ability to use pointing gestures, but also can interpret the social cognitive intentionality behind pointing gestures. We conclude that future researches on pointing gestures should integrate psychology, linguistics, biology and other multidisciplinary integration. We also offer suggestions for overcoming the drawbacks of research samples, experiment task and research method.
