In the present chapter we report experiments on the relationships between visual objects and action and between words and actions. Results show that seeing an object activates motor information and that language is also grounded in perceptual and motor systems. They are discussed within the framework of embodied cognitive science. We argue that models able to reproduce the experiments should be embodied organisms, whose brain is simulated with neural networks and whose body is as similar as possible to humans’ body. We also claim that embodied models are badly needed in cognitive psychology, as they could help to solve some open issues. Finally, we discuss potential implications of the use of embodied models for embodied theories of cognition. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
