The International Symposium on Bilingualism (ISB) is a biennial conference on a wide range of issues concerning bi/multilingualism. Since its inaugural conference in 1997 at Newcastle University, ISB has become the most significant conference in the field of bi/multilingualism. ISB has a strong focus on showcasing multidisciplinary research with a representation from a range of disciplines at every conference, including education, linguistics, neuroscience, psychology and sociology. The aim of ISB is to bring together bi/multilingualism researchers from all around the globe to advance the theoretical and applied research in bi/multilingualism, and to support bi/multilingualism practices in the community.


The conference theme of ISB15 is The Different Faces of Bilingualism

“The Different Faces of Bilingualism” is a deliberately broad theme for ISB15, aimed at meeting ISB’s mission to create a space for researchers with a diverse range of interests to share their knowledge and gain new perspectives, and to foster meaningful cross-disciplinary collaborations. We hope to bring together researchers working on different faces of bilingualism, including different research areas, methodological approaches, and populations. In line with this aim, we have invited plenary speakers who represent different faces of bilingualism, from sociolinguistics to education, psycholinguistics to translation. This broad theme reflects the multidisciplinary nature of the organizing committee, based in a center of excellence for neuroscientific research into language and bilingualism. To capitalize on this expertise, ISB15 will feature The Bilingual Brain Day, which is intended to share the core insights of the field with researchers of other areas and to discuss the state-of-the-art with researchers in the field. The conference theme also aims to promote inclusivity, inspired by its location in the Spanish Basque Country, one of the few regions in the world that has successfully revived its bilingual heritage across all aspects of society.
