Traditionally, communication has been defined as the intentional exchange of symbolic information between individuals. In contrast, the mirror system provides a basis for nonsymbolic and nonintentional information exchange between individuals. We believe that understanding the role of the mirror system in joint action has the potential to serve as a bridge between these two domains. The present study investigates one crucial component of joint action: the ability to represent others' potential actions in the same way as one's own in the absence of perceptual evidence. In two experiments a joint spatial numerical association of response codes (SNARC) effect is demonstrated, providing further evidence that individuals form functionally equivalent representations of their own and others' potential actions. It is shown that numerical (symbolic) stimuli that are mapped onto a spatially arranged internal representation (a mental number line) can activate a co-represented action in the same way as spatial stimuli. This generalizes previous results on co-representation.We discuss the role of the mirror system in co-representation as a basis for shared intentionality and communication.
传统上，沟通被定义为个体之间有意的符号信息交换。相比之下，镜像系统为个体之间非符号化和非有意的信息交换提供了基础。我们认为，理解镜像系统在联合行动中的作用有可能成为这两个领域之间的桥梁。本研究调查了联合行动的一个关键组成部分：在没有感知证据的情况下，以与自己相同的方式表征他人潜在行动的能力。在两个实验中，证明了反应编码的联合空间数字关联（SNARC）效应，进一步证明个体对自己和他人的潜在行动形成了功能上等效的表征。研究表明，映射到空间排列的内部表征（心理数字线）上的数字（符号）刺激可以与空间刺激一样，以相同的方式激活共同表征的行动。这推广了先前关于共同表征的研究结果。我们讨论了镜像系统在共同表征中的作用，将其作为共享意向性和沟通的基础。
