Reading accuracy and fluency tests were conducted on 38 primary school children, 1st to 6th grade, with developmental dyslexia. Reading duration was measured using stimuli of Hiragana and Katakana words and non-words and paragraphs. Response time was estimated using discrete Kana characters: Hiragana, Katakana and Kanji words. We found 8 children showing fluency problem only, with normal accuracy. In contrast, 3 children manifested accuracy problem only, with normal fluency. In the reading fluency test, 35 children showed 2 SD slower than the mean score of their age-matched normal children. A total of 25 out of 35 children, that is 71%, manifested more than 2 seconds delay in discrete character reading, and also showed delayed duration time in the reading speed test. These results suggest that accuracy and fluency are independent variables. It is possible that delayed response time in discrete character reading can be used to predict reading duration time in more than 70% children.
