运动动作和动作动词激活类似的大脑皮层区域。功能干扰可以作为这两种信息的平行处理的证据，并且可以证明语言在行动中的生物学基础。提出了一种新的方法来研究语言和握力之间的关系。受试者闭上眼睛，伸出手臂，一边听与手动动作相关（动词）或不相关（名词）的单词，一边拿着一个带有集成力传感器的圆柱体。当受试者听到与手动动作有关的动词时，握力发生了变化。握力在动词呈现后约100 ms增加，在380 ms时达到峰值，在400 ms后突然下降，表明这些词语可能抑制了运动模拟。这些观察结果揭示了语言和掌握之间存在的密切关系，并表明有可能在网上阐明感觉运动相互作用的新方面。
Motor actions and action verbs activate similar cortical brain regions. A functional interference can be taken as evidence that there is a parallel treatment of these two types of information and would argue for the biological grounding of language in action. A novel approach examining the relationship between language and grip force is presented. With eyes closed and arm extended, subjects listened to words relating (verbs) or not relating (nouns) to a manual action while holding a cylinder with an integrated force sensor. There was a change in grip force when subjects heard verbs that related to manual action. Grip force increased from about 100 ms following the verb presentation, peaked at 380 ms and fell abruptly after 400 ms, signalling a possible inhibition of the motor simulation evoked by these words. These observations reveal the intimate relationship that exists between language and grasp and show that it is possible to elucidate online new aspects of sensorimotor interaction.
