A identificação das categorias lexicais v(erbo) e n(ome) a partir de categorias funcionais

Abstract

This study investigates the categorization process of words that belong to lexical categories N(oun) or V(erb). Our goal is to verify if children in the early stages of the acquisition of BP are sensitive to function categories such as determiners and pronouns and if they can use these function items to categorize novel words as nouns or verbs. The theoretical approach adopted aims at conciliating a processing model of language acquisition – Phonological Bootstrapping (MORGAN and DEMUTH, 1996; CHRISTOPHE et al., 1997) with a linguistic theory that considers an interface between linguistic system and other systems – sensory-motor and conceptual-intentional systems (CHOMSKY, 1995, 1999; HAUSER; CHOMSKY and FITCH, 2002). This conciliation allows us to explain how children extract the syntactic structure of their language from the speech through distributional and prosodic cues. Previous studies with German (HÖHLE et al., 2004) and French Canadian (SHI and MELANÇON, 2010) infants indicate that fourteen-month-old infants use determiners to categorize novel words as nouns. Our hypothesis is that thirteen-month-old infants identify determiners and pronouns as belonging to distinct groups within function categories and that these items can guide the categorization process of nouns and verbs. Results of an experiment using the Preferential Looking Paradigm suggest the use of determiners and pronouns to categorize novel words either as nouns or verbs in BP by thirteen-month-old Brazilian infants.
