Is Syntax Separate or Shared between Languages? Cross-Linguistic Syntactic Priming in Spanish-English Bilinguals

Much research in bilingualism has addressed the question of the extent to which lexical information is shared between languages. The present study investigated whether syntactic information is shared by testing if syntactic priming occurs between languages. Spanish-English bilingual participants described cards to each other in a dialogue game. We found that a participant who had just heard a sentence in Spanish tended to use the same type of sentence when describing the next card in English. In particular, English passives were considerably more common following a Spanish passive than otherwise. We use the results to extend current models of the representation of grammatical information to bilinguals.
