The main goal of our project is to study the way people learn language and mathematics. We evaluate factors that might modulate the learning process by reducing cognitive efforts and maximizing the learning rate. Concretely, we focus on the acquisition, representation and processing of phonology in a second language (L2). In addition, we evaluate factors that might foster the learning of foreign languages. In particular, we study the role of gestures during the acquisition of vocabulary in L2. Our second specific goal adresses the acquisition, representation and management of numerical and arithmetic information. With the use of behavioral and brain-waves recording methods, we aim at determining the way simple arithmetic is processed in adults and acquired in children under formal education in numeracy.
