Investigating Linguistic Relativity Through Bilingualism: the Case of Grammatical Gender

The authors investigated linguistic relativity effects by examining the semantic effects of grammatical gender (present in Italian but absent in English) in fluent bilingual speakers as compared with monolingual speakers. In an error-induction experiment, they used responses by monolingual speakers to establish a baseline for bilingual speakers and show that gender affects the semantic substitution errors made by monolingual Italian speakers compared with monolingual English speakers. They then showed that Italian-English bilingual speakers behave like monolingual English speakers when the task is in English and like monolingual Italian speakers when the task is in Italian, hence exhibiting appropriate semantic representations for each language. These results show that for bilingual speakers there is intraspeaker relativity in semantic representations and, therefore, that gender does not have a conceptual, nonlinguistic effect. The results also have implications for models of bilingual semantic memory and processing.
