The ability to learn new words is a fundamental process in language acquisition that is active throughout life, although little is known about the brain mechanisms supporting it. The current project aims to employ a combined linguistics-memory approach to understand how adults form a long-term association between a novel word and its meaning. In particular, we plan to evaluate a particular phase in the word-learning process: memory reconsolidation. When a long-term memory is recalled by a reminder, it enters a vulnerability phase (labilization), followed by a process of re-stabilization (reconsolidation). It has been suggested that this process makes the incorporation of new information possible. Here, we plan to analyze the presence of reconsolidation in new word learning, using an artificial language paradigm. Our hypothesis is that when we retrieve a novel word memory trace, there is a chance for reconsolidation to occur, allowing us to updateor redefine the word s meaning. In addition, we will address the neurobiological basis of reconsolidation using event- related potentials, measured with electroencephalography. This technique will provide useful information regarding the cortical changes observed during the reconsolidating phase.
