Abstract

本研究では,発達性ディスレクシア児童23名と典型発達児童36名を対象に,2種類の書体を用いた速読課題を実施し,書体が速読所要時間,誤読数,自己修正数に与える影響を検討した.刺激は,表記(漢字仮名混じりの文章,ひらがなとカタカナで構成された無意味文字列)と書体(丸ゴシック体,明朝体)の2×2の合計4種類である.実験参加者には,4種類の刺激を速読してもらった後,どちらの書体を主観的に読みやすいと感じたか口頭で答えてもらった.その結果,発達性ディスレクシア児童群と典型発達児童群の双方において,書体間の速読所要時間,誤読数,自己修正数に有意差は認められなかった.主観的には,発達性ディスレクシア児童群では丸ゴシック体を読みやすいと感じる児童が多かった.本研究の結果からは,客観的評価と主観的評価は異なり,丸ゴシック体と明朝体の書体の違いによる正確性と流暢性に関する「読みやすさ」の指標は見出せなかった.

We conducted rapid reading tasks on Japanese children - 36 with typical development and 23 with developmental dyslexia - and investigated the effects of two different font types: Maru-Gothic and Mincho. In the experiment we used four kinds of stimuli: two scripts (text and random kana character non-words) in two font types (Maru-Gothic and Mincho). The duration time, number of errors and number of self-corrections were measured during reading. The participants were required to answer which font type is subjectively more comfortable. The results revealed no significant difference between the two font types in all participants. However, many children in the group with developmental dyslexia responded that subjectively the Maru-Gothic font was easier to read. There is a difference between objective and subjective readability. In this study, the Maru-Gothic and Mincho style fonts did not improve reading performance in children with dyslexia.
