具身理论提出，在语言理解过程中也涉及感知和行动的神经系统。之前的神经影像学和神经生理学研究只能证明在理解具体语言过程中动作系统的调节。我们为理解具体和抽象语言期间运动系统活动的调节提供神经生理学证据。在实验1中，当所描述的物体传输或信息传输方向（例如，从读者到另一个人）与用于做出响应的手部运动的字面方向匹配时，响应速度比两个方向不匹配时更快（动作-句子兼容性效应）。在实验2中，我们使用单脉冲经颅磁刺激来研究阅读相同句子时皮质脊髓运动通路到手部肌肉的变化。相对于不描述转移的句子，当阅读描述具体物体和抽象信息转移的句子时，手部肌肉的活动有更大的调节。这些发现与人类镜像神经元系统有关。
Embodiment theory proposes that neural systems for perception and action are also engaged during language comprehension. Previous neuroimaging and neurophysiological studies have only been able to demonstrate modulation of action systems during comprehension of concrete language. We provide neurophysiological evidence for modulation of motor system activity during the comprehension of both concrete and abstract language. In Experiment 1, when the described direction of object transfer or information transfer (e.g., away from the reader to another) matched the literal direction of a hand movement used to make a response, speed of responding was faster than when the two directions mismatched (an action-sentence compatibility effect). In Experiment 2, we used single-pulse transcranial magnetic stimulation to study changes in the corticospinal motor pathways to hand muscles while reading the same sentences. Relative to sentences that-do not describe transfer, there is greater modulation of activity in the hand muscles when reading sentences describing transfer of both concrete objects and abstract information. These findings are discussed in relation to the human mirror neuron system.
