许多动物使用工具来增强运动功能（“运动工具”，如耙子），而使用工具来获取感觉信息或增强感觉功能（“感觉工具”，如内窥镜）仅在人类中有报道。在本研究中，我们通过训练日本猴子获得感觉工具使用，通过运动工具使用训练重建人类特定工具使用的可能发展过程。在他们掌握了rake的使用之后，我们系统地引入了一系列外部镜子和视频的安排，从而将视觉线索与其在视觉运动空间中的实际来源分离开来。最后，猴子可以学会使用感觉工具——一种连接在耙子上的内窥镜——来探索实验空间，找到并取回食物。结果表明，环境控制在发展更高阶的行为序列中起着关键作用，比如非人类灵长类动物对人类特定感官工具的使用。
Many animals use tools to augment motor function ("motor tools", like rake), while the use of tools to acquire sensory information or to augment sensory function ("sensory tools", like endoscope) has been reported only in humans. In the present study, we trained Japanese monkeys to acquire the sensory tool use to re-construct a possible developmental course of the human-specific tool use via motor tool use training. After they mastered the rake use, we systematically introduced a series of external mirror and video arrangements, so as to separate visual cues from their actual origins in visuomotor space. Finally, the monkeys could acquire the use of sensory tool-a sort of endoscope attached to a rake-to explore the experimental space to find and retrieve the food. The results indicated a critical role of environmental control to develop even higher order behavioral sequences like human-specific sensory tool use in nonhuman primates.
