社交窃听是通过观察其他个体之间的互动来收集信息。先前的研究声称，狗，Canis familiaris，能够使用通过社会窃听获得的信息，也就是说，更喜欢慷慨的人而不是自私的人。然而，在这些研究中，在演示和狗的选择之间，这一方是恒定的，没有控制潜在的位置偏差。在我们实验的关键控制条件下，在狗选择之前，捐赠者在一半的试验中交换了位置。我们发现，狗的第一选择行为以及与慷慨的捐赠者互动的时间受到位置（侧）的影响。在第二个实验中，受试者的主人与两个捐赠者互动。同样，侧面控制的结果显示，关键因素是位置（侧面），而不是人。这些实验的结果没有提供任何证据证明狗的社会窃听，并显示了关键控制条件的重要性。(C)2014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。
Social eavesdropping is the gathering of information by observing interactions between other individuals. Previous studies have claimed that dogs, Canis familiaris, are able to use information obtained via social eavesdropping, that is, preferring a generous over a selfish human donor. However, in these studies the side was constant between the demonstrations and the dogs' choices, not controlling for potential location biases. In the crucial control condition of our experiments, the donors swapped places in half of the trials before the dogs chose. We found that first choice behaviour as well as the time dogs interacted with the generous donor were influenced by location (side). In a second experiment the subject's owner interacted with the two donors. Again, the result of the side control revealed that the critical factor was location (side) not person. The results of these experiments provide no evidence for social eavesdropping in dogs and show the importance of critical control conditions.
