C03: Conceptual shifts: psycholinguistic evidence
Project C03 investigates whether conceptual type (CT) shifts have processing consequences and, if so, at which processing level(s) they arise. These questions will be investigated with behavioral paradigms that differ with respect to their sensitivity for lexical and post-lexical processes (visual and auditory lexical decision, phoneme monitoring). The time-course and nature of the processing of type-shifts in sentences will also be investigated by comparing the electrophysiological signature of concept type incongruence to known signatures of semantic incongruence (N400) and reanalysis processes (P600). Brain regions that are involved in the representation of concept type information will be identified using the functional magnetic resonance imaging (fMRI) repetition suppression paradigm.
