Takumi Uchihara is a Distinguished Associate Professor in the department of Applied Linguistics, Graduate School of International Cultural Studies (GSICS) at Tohoku University in Japan. He is also part of a research team in Department of Human Brain Science in the Institute of Development, Aging and Cancer (IDAC: 2023~Present) and Cognitive Neuroscience Application Center (CogNAC: 2024-Present). His research interests include a wide range of topics related to second language (L2) vocabulary acquisition, instruction, and assessment. He has investigated the following topics: L2 spoken vocabulary acquisition; the effects of the quantity (i.e., repetition) and qualities of input (e.g., variability, elaboration, multimodality) on L2 vocabulary learning; the relationship between written and spoken vocabulary knowledge; the relationship between vocabulary/collocation knowledge and L2 speaking proficiency (e.g., pronunciation, oral fluency, and spoken lexical use); the relationship between vocabulary knowledge and L2 listening; incidental and intentional vocabulary learning; productive vocabulary assessment; L2 vocabulary learning and teaching in English-medium instruction (EMI) contexts. His current research focuses on examining the mechanisms of L2 incidental and intentional vocabulary learning using various data collection and analysis techniques (e.g., brain imaging and eye-tracking), acquisition of the knowledge of L2 words employable for real-life communication (e.g., listening and speaking), and phonological vocabulary learning and teaching.
