The present study assessed the functional organization of action semantics by asking subjects to categorize pictures of an actor holding objects with a correct or incorrect grip at either a correct or incorrect goal location. Overall, reaction times were slower if the object was presented with an inappropriate posture, and this effect was stronger for goal violations compared with grip violations (Experiment 1). In addition, the retrieval of action semantics was found accompanied by the implicit activation of motor representations. Body-related objects (e.g., cup) were classified faster when a movement toward the subject's body was required, whereas world-related objects (e.g.. pincers) were responded to faster with a movement in the opposite direction (Experiments 2 and 3). In contrast, when subjects were required to retrieve only visual semantics (Experiment 4), no interference effects of postural information were observed, and motor representations were only partially activated. These findings suggest that action semantics can be accessed independently from visual semantics and that the retrieval of action semantics is supported by functional motor activation reflecting the prototypical use of an object.
