研究了2种狐猴（Eulemur fulvus和Lemur catta）对工具的推理。实验1允许受试者使用2根手杖中的1根来获取无法获得的食物奖励。狐猴和其他灵长类动物一样很快学会了解决这个问题。实验2，然后提出了新的工具，从原来的不同沿着一个特征尺寸的主题。受试者对工具的大小关注程度高于颜色，对工具的形状和质地没有区分。实验3和4提出了一些问题，其中一些工具的方向必须相对于食物进行修改。受试者在这些问题上表现良好，有时会修改工具的位置。这些结果进行了讨论，根据其他灵长类动物在这项任务上的表现。
The authors examined how 2 lemur species (Eulemur fulvus and Lemur catta) reason about tools. Experiment 1 allowed subjects to use 1 of 2 canes to retrieve an inaccessible food reward. Lemurs learned to solve this problem as quickly as other primates. Experiment 2 then presented subjects with novel tools differing from the originals along one featural dimension. Subjects attended more to tools' sizes than to their colors and made no distinction between tools' shapes and textures. Experiments 3 and 4 presented problems in which some of the tools' orientations had to be modified relative to the food. Subjects performed well on these problems, sometimes modifying the position of the tool. These results are discussed in light of the performance of other primates on this task.
