Verbal fluency in Greek: Performance differences between L1Greek-L2English late bilingual and Greek monolingual speakers

Abstract

Verbal fluency data for semantic (animals, fruit and vegetables and objects) and formal fluency (X [Chi], Σ [Sigma] Α [Alpha]) were collected from 32 L1Greek-L2English late bilingual speakers and 32 Greek monolinguals. The verbal fluency task has been used in both language attrition and bilingualism studies. Language attrition studies, which mostly employ only the semantic task, show that bilinguals perform worse than monolinguals. In bilingualism studies, which employ both the semantic and formal tasks, we find greater variance and the results are mixed (bilinguals perform similarly, better or poorly compared to monolinguals). In our study, we investigated quantitative measures (number of correct responses) and strategic processes (clustering, switching). In the quantitative measures, monolinguals outperformed bilinguals in both tasks with the difference being more pronounced in the semantic task. In clustering, both groups behaved similarly, while in switching monolinguals performed better than bilinguals. The implications of these results are discussed.
