Theories of embodied cognition (EC) propose that object concepts are represented by reactivations of sensorimotor experiences of different objects. Abundant research from linguistic paradigms provides support for the notion that sensorimotor simulations are involved in cognitive tasks like comprehension. However, it is unclear whether object concepts, as accessed from the visual presentation of objects, are embodied. In the present article we review a large body of visual cognitive research that addresses 5 main predictions of the theory of EC. First, EC accounts predict that visual presentation of manipulable objects, but not nonmanipulable objects, should activate motor representations. Second, EC predicts that sensorimotor activity is necessary to perform visual–cognitive tasks such as object naming. Third, EC posits the existence of distinct neural ensembles that integrate information from action and vision. Fourth, EC predicts that relationships between visual and motor activity change throughout development. Fifth, EC predicts that the visual presentation of objects or actions should prime performance cross-modally. We summarize findings from neuroimaging, neuropsychology, neurophysiology, development, and behavioral paradigms. We show that while much of the research published so far demonstrates that there is a relationship between visual and motoric representations, there is no evidence supporting a strong form of EC. We conclude that sensorimotor simulations may not be required to perform visual cognitive tasks and highlight a number of directions for future research that could provide strong support for EC in visual cognitive paradigms.
