In this thesis, the embodied cognition proposal that action words are directly and automatically mapped into the perceiver’s sensorimotor system, and understood via motor simulation, has been put under the lenses of neuropsychology, psychophysics, transcranial magnetic stimulation (TMS), and functional magnetic resonance imaging (fMRI) investigation. The objective was to establish whether the tie between language understanding and motor simulation is necessary for the former to be effective, to the extent that a virtual identity can be recognized between action and language systems...
