Currently, little is known about how language environment influences referent identification. Comparisons between bilinguals and monolinguals offer a unique window into this interaction. The aim of this dissertation is to explore how bilinguals and monolinguals acquire words for categories at different ages as well as their use of disambiguation strategies. Specifically, we asked whether bilinguals' early advantage in executive function, together with the need to learn in noisier contexts, may translate into different word learning strategies. In Experiments 1-4, we tested 8-, 15-, and 19-month-old infants with a fast categorization task. We also explored if recently acquired knowledge can be used to boost the learning of other information. In Experiments 5-6, we tested 18- and 19-month-old infants with a familiarization/preferential-looking task on their ability to acquire categories. We asked whether different linguistic experiences may lead bilinguals and monolinguals to form different category representations. Our findings suggest a much more complex picture of the influence of linguistic experience on referent identification than currently acknowledged.Per tal de trobar els referents de les paraules, els infants confien en requeriments que guien les seves interpretacions. Actualment, se sap poc sobre com l'entorn lingüístic influencia la identificació de referents. La comparació de bilingües i monolingües ofereix una finestra única per explorar aquesta interacció. L'objectiu d'aquesta tesi és explorar com bilingües i monolingües adquireixen noms per categories a diferents edats així com l'ús que fan d'estratègies de desambiguació. Específicament, ens preguntem si l'avantatge primerenc en les funcions executives en bilingües junt amb la necessitat d'aprendre en contextos sorollosos, pot traduir-se en estratègies d'aprenentatge de paraules diferents. Als Experiments 1-4, van testejar infants de 8, 15 i 19 mesos amb una tasca de categorització ràpida. També vam explorar si coneixement recentment adquirit pot ser utilitzar per promoure l'aprenentatge d'altra informació. Als Experiments 5-6, vam testejar infants de 18 i 19 mesos amb una tasca de familiarització/mirada-preferencial en l'habilitat d'adquirir categories. Ens preguntem si diferències en l'experiència lingüística poden dur bilingües i monolingües a formar diferents representacions de categories. Els resultats suggereixen una fotografia més complexa sobre la influència de l'experiència lingüística en l'habilitat d'identificar referents del que actualment es reconeix.Programa de doctorat en BiomedicinaUniversitat Pompeu FabraCosta, AlbertBonatti, LucaUniversitat Pompeu Fabra.
