Gagnon和Dore（1992）表明，家犬能够解决皮亚杰的物体永久性任务，称为不可见位移问题。玩具被藏在一个容器中，该容器被移动到一个屏幕后面，玩具被移走并留在那里。狗在这些问题中犯的错误比在可见位移测试中犯的错误要多，在可见位移测试中，物体直接隐藏在目标屏幕后面。在实验1中，我们研究了不可见位移的标准程序的组件，这些组件可能会使隐藏位置的编码或保留比可见位移更困难。在实验2中，我们比较了狗的表现在可见和不可见的位移问题时，延迟0，10，和20秒之间的对象的最终消失和主题的释放。结果显示，狗在不可见位移测试中的表现较差，这与必须编码或记忆的复杂事件序列以及难以表示发出信号但不能直接感知的位置变化有关。
Gagnon and Dore (1992) showed that domestic dogs are able to solve a Piagetian object permanence task called the invisible displacement problem. A toy is hidden in a container which is moved behind a screen where the toy is removed and left. Dogs make more errors in these problems than they do in visible displacement tests, in which the object is hidden directly behind the target screen. In Experiment 1, we examined components of the standard procedure of invisible displacements that may make encoding or retention of the hiding location more difficult than it is in visible displacements. In Experiment 2, we compared dogs' performances in visible and invisible displacement problems when delays of 0, 10, and 20 sec were introduced between the object's final disappearance and the subject's release. The results revealed that dogs' poorer performance in invisible displacement tests is related to the complex sequence of events that have to be encoded or remembered as well as to a difficulty in representing the position change that is signaled, but not directly perceived.
