这项研究调查了三只黑猩猩和三只红毛猩猩在一系列位移后跟踪奖励位置的能力。奖金被放在平台上两个不透明容器中的一个下面。实验1研究了平台旋转0 °、180 °和360 °的旋转位移。实验2研究了换位位移，其中平台保持静止，而容器保持静止，或交换它们的位置（在一个-两个-或三个步骤的序列）。在这两个实验中，奖励的初始位置是通过直接在容器下显示奖励，或者通过在诱饵容器的顶部放置一个先前与奖励相关的地标来指示的。受试者成功地跟踪奖励通过旋转和换位时，他们看到了它，但他们的表现大大恶化时，地标表示奖励的初始位置，即使受试者成功地使用地标找到奖励的情况下位移。这种减少在旋转位移中尤其明显。一只受过语言训练的猩猩胜过其他所有猿类，解决了所有问题。
This study investigated the ability of three chimpanzees and three orangutans to track the position of a reward after a series of displacements. The reward was placed under one of two opaque containers resting on a platform. Experiment 1 investigated rotational displacements in which the platform was rotated 0degrees, 180degrees, or 360degrees. Experiment 2 investigated transpositional displacements in which the platform remained stationary while the containers either remained stationary, or swapped their positions (in a one- two- or three-step sequence). In both experiments, the initial position of the reward was indicated either by directly showing the reward under the containers, or by placing a landmark, which had been previously associated with the reward, on top of the baited container. Subjects successfully tracked the reward through rotations and transpositions when they had seen it, but their performance substantially deteriorated when the landmark indicated the reward's initial position, even though subjects successfully used the landmark to find the reward in the absence of displacements. This decrease was especially pronounced in rotational displacements. A language-trained orangutan outperformed all the other apes and solved all problems.
