神经科学的最新发现挑战了运动系统专门用于控制动作的观点，并且有人认为它可能对概念过程（如涉及语言和数字表征的过程）起关键作用。这篇综述的目的是通过说明运动系统与文字和数字处理之间的一些相互作用来解决这个问题。首先，我们详细介绍了功能性脑成像研究，表明运动回路可能被招募来代表与动作相关的单词的含义。其次，我们总结了一系列实验，证明了用于抓取物体的握力大小与单词或数字的大小处理之间存在一些干扰。第三，我们报告的数据暗示了成人大脑中数字和手指运动的共同表征，这可能是儿童时期使用的手指计数策略的痕迹。总之，这些研究表明，运动系统与单词和数字表征的几个方面相互作用。未来的研究应该确定这些发现是否反映了运动系统在语义知识组织中的因果作用。
Recent findings in neuroscience challenge the view that the motor system is exclusively dedicated to the control of actions, and it has been suggested that it may contribute critically to conceptual processes such as those involved in language and number representation. The aim of this review is to address this issue by illustrating some interactions between the motor system and the processing of words and numbers. First, we detail functional brain imaging studies suggesting that motor circuits may be recruited to represent the meaning of action-related words. Second, we summarize a series of experiments demonstrating some interference between the size of grip used to grasp objects and the magnitude processing of words or numbers. Third, we report data suggestive of a common representation of numbers and finger movements in the adult brain, a possible trace of the finger-counting strategies used in childhood. Altogether, these studies indicate that the motor system interacts with several aspects of word and number representations. Future research should determine whether these findings reflect a causal role of the motor system in the organization of semantic knowledge.
