Abstract

•When listeners recognize spoken words, similar sounding words inhibit each other.•Sleep was thought to be essential for the acquisition of these inhibitory links.•We report inter-lexical inhibition after 20min of training and without sleep.•Knowledge of a word sound and its links to other words might emerge simultaneously.\nIt is well known that familiar words inhibit each other during spoken word recognition. However, we do not know how and under what circumstances newly learned words become integrated with the lexicon in order to engage in this competition. Previous work on word learning has highlighted the importance of offline consolidation (Gaskell & Dumay, 2003) and meaning (Leach & Samuel, 2007) to establish this integration. In two experiments we test the necessity of these factors by examining the inhibition between newly learned items and familiar words immediately after learning.\nParticipants learned a set of nonwords without meanings in active (Experiment 1) or passive (Experiment 2) exposure paradigms. After training, participants performed a visual world paradigm task to assess inhibition from these newly learned items. An analysis of participants’ fixations suggested that the newly learned words were able to engage in competition with known words without any consolidation.
