Lexical ambiguity resolution & bilingual language experience: Evidence from Albanian-Greek bilingual children of immigrant families

The present study aims at exploring lexical ambiguity resolution in bilingual children employing homonym meaning activation. Specifically, we are examining the processing of Greek homonyms in relation to the language input, verbal ability and cognitive capacity of 10–12 years old bilingual children raised in an immigrant context, in which Albanian is their heritage language and Greek is the majority language. We systematically assessed sentence context effects in homonym meaning activation using a cross-modal priming task. Primes were sentences biasing towards the dominant, subordinate, or neither meaning of a sentence-final homonym while visual targets were related to either meaning of the homonym. To measure the bilingual language experience and address variability issues in the dataset, we administered a background questionnaire that focused on acquisition history, bi-literacy practices and self-reported competence in each language along with a standardized test for verbal ability in Greek. The study's findings show that frequency and context are significant parameters in the examination of ambiguity resolution and underline the contribution of verbal working memory to lexical processing. Additionally, our results highlight the role of the bilingual language experience in the function of the mental lexicon and the potential benefits of bi-literacy development.
