The effect of coloured overlays on reading speed in Japanese children with developmental dyslexia

我们进行了阅读任务的日本儿童发展性阅读障碍的控制实验条件下，以揭示颜色和亮度因素的影响，彩色覆盖阅读速度。本研究以42名正常儿童和33名发展性阅读障碍儿童为研究对象，对平假名词、片假名词、平假名非词、片假名非词和句子的阅读任务的持续时间进行了研究。在有和没有彩色覆盖和中性密度覆盖的情况下测量阅读任务的持续时间。所有被试在三种条件下的阅读时长没有显著差异。我们的研究结果表明，使用彩色覆盖不会提高阅读速度的日本儿童发展性阅读障碍。

We conducted reading tasks in Japanese children with developmental dyslexia under controlled experimental conditions in order to reveal the effect of the colour and luminance factors by coloured overlays on reading speed. We evaluated the duration time of reading tasks of hiragana words, katakana words, hiragana non-words, katakana non-words, and sentences in Japanese speaking children(42normal, 33with developmental dyslexia). The durationtime of the reading tasks was measured with and without coloured overlays and neutraldensity overlays. All participants did not show a significant difference in the reading durationunder the three conditions. Our results suggest that using coloured overlays does not improve reading speed in Japanese children with developmental dyslexia.
