debate how we mentally represent concepts as diverse as cat, democracy, and fear. Grounded theories of representation hold that the same neural systems engaged during perceptual and action experience are also engaged when meaning is processed during language comprehension and other conceptual tasks. In other words, the conceptual system has effectively co-opted the sensorimotor system for the purposes of representation. I discuss two critical corollaries of this perspective. First, all concepts in long-term memory must be sensorimotor to some extent: because conceptual processing relies on sensorimotor neural systems, it provides a grounding mechanism for all concepts, even traditionally abstract ones, meaning that there is no such thing as a non-sensorimotor concept. Second, ongoing perception and action must affect conceptual representation in short-term (working) memory: because conceptual information is grounded in sensorimotor systems, concurrent sensorimotor processing of the surrounding environment affects what is retrieved and represented during conceptual processing. I present recent work from my lab that illustrates the sensorimotor basis of a full-size conceptual system of approximately 40 thousand concepts, and demonstrates how sophisticated categorical structure emerges spontaneously from sensorimotor experience across both concrete and abstract domains. I also review experimental evidence showing that representational content depends on how ongoing perceptual demands direct attention to modality-specific systems. These findings illustrate that theories and models of meaning must not only acknowledge that conceptual knowledge is grounded in sensorimotor systems, but also incorporate the ability of current bodily states to systematically alter the content of conceptual representations.
