It is currently debated whether the meanings of words and objects are represented, in whole or in part, in a modality-specific format-the embodied cognition hypothesis. I argue that the embodied/disembodied cognition debate is either largely resolved in favor of the view that concepts are represented in an amodal format, or at a point where the embodied and disembodied approaches are no longer coherently distinct theories. This merits reconsideration of what the available evidence can tell us about the structure of the conceptual system. We know that the conceptual system engages, online, with sensory and motor content. This frames a new question: How is it that the human conceptual system is able to disengage from the sensorimotor system? Answering this question would say something about how the human mind is able to detach from the present and extrapolate from finite experience to hypothetical states of how the world be. It is the independence of thought from perception and action that makes human cognition special-and that independence is guaranteed by the representational distinction between concepts and sensorimotor representations.
目前存在争议的是,单词和物体的意义是否全部或部分以特定模态的形式呈现——即具身认知假说。我认为,具身认知与非具身认知的争论要么在很大程度上已得到解决,支持概念以无模态形式呈现的观点,要么已到了具身认知和非具身认知方法不再是连贯清晰的不同理论的阶段。这值得重新思考现有证据能告诉我们关于概念系统结构的哪些信息。我们知道,概念系统在在线状态下会涉及感觉和运动内容。这就引出了一个新问题:人类概念系统是如何与感觉运动系统脱离的?回答这个问题将有助于说明人类思维是如何能够脱离当下,并从有限的经验推断出世界可能的假设状态的。正是思维与感知和行动的独立性使人类认知变得特殊——而这种独立性是由概念与感觉运动表征之间的表征差异所保证的。
