我们研究了狗从人类的视角看问题的能力。在主要研究中，两个玩具中的每一个都被放置在两个小障碍物（一个不透明，一个透明）的狗的一侧。在实验条件下，一个人坐在屏障的对面，这样她只能看到透明屏障后面的玩具。然后实验者告诉狗“把它带到这里来！””（不以任何方式指定任何一个玩具）。在背转控制中，E也坐在对面，但她背转，这样她就看不到任何玩具，在同一侧控制中，她坐在狗的同一侧，这样她就可以看到两个玩具。当玩具是可区分的，狗接近玩具后的透明屏障在实验中相比，背转身和同侧条件。犬无法区分两种对照条件。在第二项研究中，狗对人类在最近的过去看到或没有看到的东西并不敏感。这些结果表明，即使在没有明显的行为线索的情况下，狗对他人的视觉访问也很敏感，即使这与他们自己的视觉访问不同。
We investigated dogs' ability to take the visual perspective of humans. In the main study, each of two toys was placed on the dog's side of two small barriers (one opaque, one transparent). In experimental conditions, a human sat on the opposite side of the barriers, such that she could see only the toy behind the transparent barrier. The experimenter then told the dog to 'Bring it here!' (without designating either toy in any way). In the Back Turned control E also sat on the opposite side but with her back turned so that she could see neither toy, and in the Same Side control she sat on the same side as the dog such that she could see both toys. When toys were differentiable dogs approached the toy behind the transparent barrier in experimental as compared to back turned and same side condition. Dogs did not differentiate between the two control conditions. In a second study dogs were not sensitive to what a human had or had not seen in the immediate past. These results suggest that, even in the absence of overt behavioural cues, dogs are sensitive to others visual access, even if that differs from their own.
