Abstract
The ability to efficiently process presuppositions, which contain information that the speaker believes to be in the background to the conversation, is essential for effective communication. To get a deeper understanding of the nature and the time-course of temporal presupposition processing, we examined event-related potential evoked by the word again in two types of sentence contexts. The word again was presented in contexts that supported a presupposition (e.g. Jake had tipped a maid at the hotel once before. Today he tipped a maid at the hotel again … ) or violated it (e.g. Jake had never tipped a maid at the hotel before. Today he tipped a maid at the hotel again … ). The presupposition violation was associated with increased amplitudes of the P3b/P600 but not the N400 component. We argue for the centrality of the P3b/P600 component for presupposition processing. These findings demonstrate rapid integration of lexical presuppositions with contextual knowledge.
