| Outline of Final Research Achievements |
In this research project, we demonstrated that the script types of Japanese word distractors (kana vs. romaji) modulated the results in the color-naming Stroop task. In addition, we also found that, when learning novel Japanese words, the data patterns in picture naming tasks using those novel words changed depending on the script types (kanji vs. kana). These results indicate that phonological and orthographic processing systems are interacting with each other.

| Academic Significance and Societal Importance of the Research Achievements |
一般に，我々はまず話し言葉を習得し，その後に書き言葉を習得する。これを受けて，話し言葉の音韻処理システムから書き言葉の形態処理システムへの影響はこれまでに数多く検討されてきたが，その逆についてはあまり考慮されてこなかった。これに対して，本研究では両システムが相互に影響し合う可能性を示したことから，本研究の成果は既存の言語処理モデルの根本的な見直しを迫ることが予想される。
