文献概要

A　櫻井　異なるという立場から　1

　「『漢字』と『ひらがな』が脳の中で知覚される部位は異なる」という知見はテレビのクイズ番組でも出題されたことがある。いまや周知の事実なのかもしれない。しかしながら，この根拠となる事実を多数例で検討した論文は意外と少ない。多くは，単一症例報告である。

　本紙上討論では，漢字とひらがなの視覚処理が異なるという立場から，これまでの病巣研究の成果をレヴューし，また機能画像研究でこの「漢字・仮名問題」（本論でいう仮名は特に断らない限り，ひらがなを指す）がどう捉えられてきたかを概説した後で，漢字処理，仮名処理に特化した部位について考察する。なお厳密な意味でのレヴューではないので，文献リストは最小限にとどめた。
