The N400-concreteness effect reflects the retrieval of semantic information during the preparation of meaningful actions
چکیده انگلیسی
The present ERP study investigated when and how action semantics, i.e. the conceptual knowledge that we acquired over the course of our lives, is activated during the preparation of object-directed actions. Subjects were required to grasp one of two objects and were implicitly instructed to either perform a meaningful action (e.g. moving a cup towards the mouth) or a meaningless action with the object (e.g. moving a cup towards the eye). A larger anterior N400 was found for the preparation of meaningful compared to meaningless actions, likely reflecting the retrieval of action semantic information in case a meaningful action was required with the object. The distribution and the latency of the anterior N400-effect were strongly related to standard N400-repetition effects, thereby further corroborating the semantic nature of the effect. In sum, the present study provides new insight in the neural and temporal dynamics underlying semantics for action.
