Nowadays, television programmes are not only accessed through a conventional TV set; they can be viewed through streaming services on the internet, smartphones, and tablets to name but a few media. For language learners, this development has opened up opportunities for accessing authentic materials in foreign languages outside of the classroom. Studies have shown that the simultaneous presentation of aural and visual information in captioned audiovisuals in a foreign language has the potential to improve language learners' listening skills (Mitterer & McQueen, 2009). Recent research has prompted extension of this discussion to online language learning behaviour and to analyses of what information learners attend to while watching captioned programmes (Vanderplank, 2015). This doctoral research seeks to contribute to this new perspective and explores actual viewing behaviour of native speakers and language learners of Japanese while watching a captioned Japanese variety show through the use of eye-tracking and questionnaires. This paper discusses the context and methodology of this study as the data analysis is in its initial phase. It is hoped that the results will deepen our understanding of language learners' reception of Japanese captions and make suggestions as to how such authentic material can complement Japanese language learning.[For the complete volume, see ED578177.]
