具身认知促进运动系统参与认知加工，如工具识别。尽管神经心理学研究表明，运动系统不是识别工具所必需的，但它仍可能在工具识别中发挥作用。为了测试这种可能性，我们使用了一个运动干扰任务：参与者在命名工具和动物的图片时，用一只手挤压一个橡皮球。与手柄朝向挤压手的工具相比，参与者在命名手柄朝向挤压手的工具时更快、更准确。动物不受定向的影响。假设受试者用最靠近手柄的手模拟握持工具，这一结果表明，干扰模拟抓握的能力会损害工具命名，并表明运动模拟在工具识别中具有功能作用。
Embodied cognition promotes the involvement of the motor system in cognitive processing, such as tool identification. Although neuropsychological studies suggest that the motor system is not necessary for identifying tools, it may still have a functional role in tool recognition. To test this possibility, we used a motor interference task: Participants squeezed a rubber ball in one hand while naming pictures of tools and animals. Participants were faster and more accurate in naming the tools that were oriented with the handle facing away from the squeezing hand than in naming the tools that were oriented with the handle facing toward the squeezing hand. There was no effect of orientation for animals. Given that participants simulate grasping a tool with the hand closest to the handle, this result demonstrates that interfering with the ability to simulate grasping impairs tool naming and suggests that motor simulation has a functional role in tool identification.
