目光跟随是一种基本的社会认知技能，对于生活在社会群体中的动物来说具有许多潜在的好处。已知至少有五种灵长类动物会跟随同种动物的目光，但还没有对其他哺乳动物的目光跟随进行研究。我们研究了家山羊是否可以利用同种山羊的注视方向作为寻找食物的线索。他们能够做到这一点，其水平与灵长类动物相当。在第二个实验中，我们测试了山羊在所谓的对象选择情况下使用人类给出的凝视和其他交流线索的能力。一名实验者将食物藏在受试者看不到的两个杯子中的一个下面。在杯子上装上诱饵后，实验者通过使用不同的提示向受试者指示食物的位置。山羊使用交流线索（触摸和指向），但不单独凝视。由于家养狗非常擅长这项任务，而狼则不然，因此一个假设是，在对象选择任务中使用交流线索是驯化的副作用。 (C) 2004 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Gaze following is a basic social cognitive skill with many potential benefits for animals that live in social groups. At least five primate species are known to follow the gaze of conspecifics, but there have been no studies on gaze following in other mammals. We investigated whether domestic goats can use the gaze direction of a conspecific as a cue to find food. They were able to do this, at a level comparable to that off primates. In a second experiment, we tested goats' ability to use gaze and other communicative cues given by a human in a so-called object choice situation. An experimenter hid food out of sight of the subject under one of two cups. After baiting the cup the experimenter indicated the location of the food to the subject by using different cues. The goats used communicative cues (touching and pointing) but not gaze by itself. Since domestic dogs are very skilled in this task, whereas wolves are not, one hypothesis is that the use of communicative cues in the object choice task is a side-effect of domestication.
