The authors investigated the type of spatial information that controls domestic dogs' (Canis familiaris) search behavior in a situation in which they have to locate a spatial position where they saw an object move and disappear. In Experiments 1 and 2, the authors manipulated all local and global sources of allocentric spatial information surrounding the hiding location. The results revealed that dogs relied on an egocentric frame of reference. Experiment 3 showed that dogs also encoded allocentric information when egocentric information was irrelevant. The authors conclude that dogs simultaneously encode both egocentric and allocentric spatial information to locate a spatial position, but they primarily base their search behavior on an egocentric frame of reference. The authors discuss under which natural conditions dogs might use these 2 sources of spatial information and detail the nature of spatial egocentric information and the circumstances underlying its use by dogs.
作者们研究了在一种情境中控制家犬（犬属家犬）搜索行为的空间信息类型，在这种情境下，它们必须找到一个它们看到物体移动并消失的空间位置。在实验1和实验2中，作者们操控了隐藏位置周围所有以自我为中心的空间信息的局部和全局来源。结果显示，狗依赖于以自我为中心的参照系。实验3表明，当以自我为中心的信息不相关时，狗也会编码以自我为中心的信息。作者们得出结论，狗在定位空间位置时会同时编码以自我为中心和以自我为中心的空间信息，但它们主要基于以自我为中心的参照系来进行搜索行为。作者们讨论了在哪些自然条件下狗可能会使用这两种空间信息来源，并详细说明了空间自我中心信息的性质以及狗使用它的潜在情况。
