与具体物体有关的交流、语言和概念知识可能依赖于它们产生的感觉运动系统。然而，抽象概念如何从这些系统中产生仍然是未知的。在这里，我们报告一个特定的有意义的手指运动，如手指握关闭，和一个抽象的概念，数值大小之间的功能性相互作用。参与者在感知到生物或非生物手部运动之前或之后都要回忆阿拉伯数字。结果表明，感知握杆闭合会减慢对大数量级数字的处理。重要的是，我们表明，这种电机-语义的相互作用不同于反向语义-电机的相互作用，并且它不产生于一般的运动幅度处理，因为它只观察到生物手部运动。这些结果证明了数字意义和目标导向的手指运动之间的功能联系，并显示了抽象概念语义如何从大脑的感觉运动回路中产生。(C)2009 Elsevier B.

Communication, language and conceptual knowledge related to concrete objects may rely on the sensory-motor systems from which they emerge. How abstract concepts can emerge from these systems is however still unknown. Here we report a functional interaction between a specific meaningful finger movement, such as a finger grip closing, and a concept as abstract as numerical magnitude. Participants were presented with Arabic digits to recall before or after they perceived a biological or non-biological hand movement. The results show that perceiving a grip closing slows down the processing of large magnitude numbers. Importantly, we show that this motor-to-semantic interaction differs from the reverse semantic-to-motor interaction, and that it does not result from a general movement amplitude processing as it is only observed for biological hand movements. These results demonstrate the functional link between number meaning and goal-directed finger movements, and show how abstract concept semantics can emerge from the sensory-motor circuits of the brain.
