一些研究试图通过调查非人类动物的工具使用行为来揭示物理因果理解的进化机制。大鼠是神经科学和生理心理学等许多领域实验中最常用的物种之一，但尚未建立研究啮齿动物机制的行为任务。本研究实施了一种新的训练范式：在实验装置中提供了一个耙形工具，没有奖励。如果老鼠横向操纵耙子超过特定的距离，实验者会取回耙子并用手提供奖励。在训练过程中，老鼠从未直接用工具获得食物，工具也从未接触过奖励。在测试中，耙子被放置在仪器的中心，奖励被放置在耙子的左侧或右侧。在测试之前，老鼠没有用工具获得奖励的经验，在测试过程中，它们无法使用这种简单的策略来操纵耙子朝着奖励的方向移动。八只老鼠中的一只可以根据奖励的位置来操纵耙子。本研究提供了一个工具使用任务，以揭示物理因果理解的进化机制。
Several studies have attempted to reveal the evolutionary mechanisms of physical causal understanding in non-human animals by investigating their tool-use behavior. Rats are one of the most commonly used species in experiments in many fields, including neuroscience and physiological psychology, but behavioral tasks for investigating the mechanisms in rodents have not yet been established. The present study implemented a novel training paradigm: a rake-shaped tool was presented in the experimental apparatus without a reward. If rats manipulated the rake laterally over specific distances, the experimenter retrieved the rake and offered the reward by hand. The rats never obtained food directly with the tool during training, and the tool never touched the reward. In the test, the rake was placed at the center of the apparatus, and the reward was placed on either the left or right side of the rake. The rats had no prior experience of obtaining the reward with the tool before the test, and they could not use this simple strategy to manipulate the rake in the direction of the reward during the test. One of eight rats could manipulate the rake according to the position of the reward. The present study offers a tool-use task to reveal the evolutionary mechanisms of physical causal understanding.
