Field of interest
My research interests focus on the psychology of second language acquisition. I am particularly interested in how the knowledge of learners’ L1 (mother tongue) and L2 (the second, third etc. language(s)) possibly interact in various L2 situations. I adopt an interdisciplinary approach (linguistic and psychological), and analyze speech as well as gestures which co-occur with speech. The domains of language use that I am interested are those of space and time. I am also interested in language pedagogy with a specific focus on Japanese as a second language.
