Outline of Final Research Achievements

This study investigated, using the pretest-posttest design, whether short handwriting activity and daily handwriting habits affect the way Japanese readers recognize visually presented kanji characters. Native speakers of Japanese were asked to complete two kanji character recognition experiments. Between the two experiments, the participants were asked to write down kanji words either by hand or with a keyboard for a short period. Participants also responded to a daily writing habit questionnaire. The study found that short handwriting activity does not alter the way kanji characters are processed. However, in the second character recognition experiment, participants processed simpler left-right kanjis quickly, indicating that writing activity, regardless of whether it is handwriting or keyboarding, might affect the word recognition process.

Academic Significance and Societal Importance of the Research Achievements

近年見られる手書き活動の減退(文化庁, 2013)が、ライティング活動の円滑さという問題を超えて、私たちの頭の中の単語の認知プロセスにも影響を与えているのではないかという疑問を解決するために、本研究では短時間のライティング活動(手書き, タイピング)と長期的なライティング習慣の単語認知プロセスへの影響を検証した。結果、短時間のライティング活動時のライティング方法は漢字の認知プロセスに大きく影響しないことがわかったが、長期的なライティング習慣は漢字の処理に影響している可能性が見られた。本研究はこれまで行われてきた手書きvs. タイピングの議論に科学的なエビデンスを提供する。
