执行一个动作并观察它会激活相同的动作的内部表征。因此，这些表征在自我和他人之间共享(共享行为表征，SRA)。但共享的到底是什么呢？在电机系统的等级结构中，SRA发生在什么级别？了解SRA的内容对于决定SRA可以执行哪些理论工作是重要的。在本文中，我们通过提出三个主要问题来澄清概念：(I)SRA是动作的语义表征还是语用表征？：(Ii)SRA是感觉表征还是运动表征？(Iii)SRA表征是作为一个整体单位还是作为一组基本运动成分来表征动作？在勾勒出马达层次的模型之后。我们的结论是，SRA的最佳候选者是行动中的意图，定义为动态运动序列的运动计划。我们通过强调行动中意图的因果效力，为SRA提供了新的线索。这反过来又解释了抑制模仿等现象。
Performing an action and observing it activate the same internal representations of action. The representations are therefore shared between self and other (shared representations of action, SRA). But what exactly is shared? At what level within the hierarchical structure of the motor system do SRA occur?" Understanding the content of SRA is important in order to decide what theoretical work SRA can perform. In this paper, we provide some conceptual clarification by raising three main questions: (i) are SRA semantic or pragmatic representations of action?: (ii) are SRA sensory or motor representations?: (iii) are SRA representations of the action as a global unit or as a set of elementary motor components'? After outlining a model of the motor hierarchy. we conclude that the best candidate for SRA is intentions in action, defined as the motor plans of the dynamic sequence of movements. We shed new light on SRA by highlighting the causal efficacy of intentions in action. This in turn explains phenomena such as inhibition of imitation.
