| Outline of Final Research Achievements |
The current research examined brain function (e.g., frontal cortex, extended amygdala, and amygdala function) associated with emotional language processing and inhibitory control using psychological surveys, neuro-cognitive measures (i.e., Go-No Go task), and fMRI scans of Japanese young adults learning English as a second language. Questionnaire surveys were collected from 183 participants, data collection for neuro-cognitive measures was obtained from 75 participants and 15 participants completed fMRI data collection. Results obtained from this project have been submitted to an international, high impact, peer reviewed scientific journal and is currently under review. Data from this project were also presented at the 2021 Hawaii International Conference on Education and at the 2021 Annual Meeting for the Society for Neuroscience.

| Academic Significance and Societal Importance of the Research Achievements |
母語で情報を処理する場合と第二言語・外国語で情報を処理する場合の脳機能と感情コントロールの関係は、いまだ研究が進んでいない。本研究では、質問紙、コンピュータータスク、脳機能イメージングを用いて、母語または第二言語・外国語で感情コントロールを測定するタスクに取り組んだ際の、脳機能の潜在的な差異を検証した。その結果、感情に関する脳の領域（拡張扁桃体）は、第二言語・外国語と比較して、母語でタスクを完了した場合に、より活性化する可能性があることが示唆された。
