Title: Dealing with ambiguity in the lexicon: a challenge for language acquisition

Abstract: The lexicon is ambiguous: word forms can have several meanings (homophones) and form a highly connected network in the phonological space with regions of high neighborhood density. While this organization might be functional for a mature language processing system, it poses a number of challenges for the language learner. Using lexical models and experimental methods in toddlers and adults, I investigate the organization of lexicons and how does it affect learning of similar sounding words (neighbors) and homophones. The study of homophones and confusable words reveal crucial details of learners? implicit knowledge and assumptions about how word forms map onto meanings and how the semantic lexicon as a whole is structured.
