Referential choice in two languages: The role of language dominance

Aims and Objectives: Bilingual speakers that speak a null subject (Spanish) and a non-null subject language (English) may show some indeterminacy in referential choice in their nondominant language in comparison to monolingual speakers. The present study tests the production of referring expressions in the two languages of bilingual speakers (Spanish and English) to assess attainment at the discourse level and explore the role of language dominance on referential choice. Methodology: A group of 49 Spanish-English bilinguals participated in a picture description task in English and Spanish measuring referential choice in contexts of reference maintenance and topic-shift. Data and Analysis: The results of our study show that at a group level, bilingual speakers produced more underspecified references in maintenance contexts than English monolingual speakers and produced more overspecified references in topic-maintenance and topic-shift contexts than Spanish monolingual speakers. The results further show that language dominance in the target language is associated with more monolingual-like referential choice. Conclusions: We discuss the role of language dominance in the development of bilingual referential choice patterns.
