Jieun Ahn (안지은)

Hello, my name is Jieun Ahn. I am a lecturer in Early Childhood English Education at Yonsei University. I earned my Ph. D. in Second Language Studies (SLS) from Michigan State University. At MSU, I was awarded a full research assistantship for the SLS program and worked as a research assistant under Drs. Aline Godfroid, Susan Gass, and Paula Winke.

My research interests involve second language (L2) acquisition, psycholinguistics, L2 reading, young learners, English-medium instruction, and eye-tracking methodology. My work specifically addresses questions like the following: How do cognitive processes change over time in implicit and explicit learning? How does working memory affect L2 development? How do we measure implicit and explicit knowledge? To explore these research questions, I have employed psycholinguistic techniques, such as eye-tracking and reaction times. For dissertation research, I obtained a personal portable eye-tracker, the Portable Duo (SR research), and set up the first satellite version of the SLS eye-tracking lab. My research articles can be found in journals such as Bilingualism: Language and Cognition, TESOL Quarterly, and Language Learning and Technology among others.
