| Outline of Final Research Achievements |
The following findings were obtained regarding the similarities and/or dissimilarities of brain activation of Japanese learners during the written tasks and conversation. Both the prefrontal cortex and the language areas were more activated during conversation than during the written tasks. The hemispheric dominance could not be generalized to each individual or task. It seemed to reflect the complexity of brain activities due to the different learning stages and language tasks. The rearrangement tasks activated the brain the most. In that respect, they were closer to the conversation tasks. As far as the examined upper-intermediate learners were concerned, the four-option multiple-choice tasks or Japanese reading comprehension tasks exhibited a higher degree of similarities. In terms of whether we should use oxy-hemoglobin or deoxy-hemoglobin as the main indicator for the experiment, we confirmed the importance of continuing to pay attention to the deoxy-hemoglobin data.

| Academic Significance and Societal Importance of the Research Achievements |
日本語教育を含め、現代の外国語教育においては、文法や単語などの知識偏重から実際の会話力／運用力を重視するようになっている。しかし、実際問題として、教育現場では教育成果を検証する方法として筆記テストに頼っている部分が大きい。筆記テストを会話力向上やその評価に有効に使うことができれば、教育現場でのメリットは大きいと言える。本研究では、日本語学習者の筆記テスト時と日本語会話時の脳活動の近似性・相違性についての知見を蓄積してきている。研究結果の将来的な応用としては、脳活動の質的・量的な近似性・相違性という新しい視点から、会話力の推定（評価）や向上に寄与する筆記テストの開発が考えられる。
