跨文化研究表明，发展性阅读障碍（DD）的阅读缺陷可以通过正字法深度来调节。为了进一步探讨这个问题，并评估正字法深度在阅读障碍和典型读者的发展认知轨迹中的调节作用，我们系统地回顾了2013年至2018年发表的113项关于DD的研究，并选择了79项参与者接受了正式的DD诊断。每项研究均根据正字深度（深与浅）和参与者年龄（儿童与成人）进行分类。我们评估了DD组和对照组在阅读任务和与阅读相关的广泛认知领域（语音意识（PA），快速自动化命名（RAN），短期工作记忆（WM）和非语言推理）中的表现差异，包括年龄和拼写作为调节因素。我们发现年龄与正字法的交互作用对单词阅读准确性有显著影响，年龄对假词阅读准确性有显著影响，但我们没有发现年龄和正字法深度对流畅性参数的影响。这些结果表明，阅读速度是一个可靠的指标区分DD和控制组之间的欧洲拼写从童年到成年。PA、RAN和短期/WM出现了类似的结果模式。我们的研究结果进行了讨论，同时考虑到正字法的深度和发展水平的临床实践的影响。在线版本包含补充材料，可通过10.1007/s11881-021-00226-0获得。
Cross-cultural studies have suggested that reading deficits in developmental dyslexia (DD) can be moderated by orthographic depth. To further explore this issue and assess the moderating role of orthographic depth in the developmental cognitive trajectories of dyslexic and typical readers, we systematically reviewed 113 studies on DD that were published from 2013 to 2018 and selected 79 in which participants received an official DD diagnosis. Each study was classified according to orthographic depth (deep vs. shallow) and participant age (children vs. adults). We assessed the difference between DD and control groups’ performance in reading tasks and in a wide range of cognitive domains associated with reading (phonological awareness (PA), rapid automatized naming (RAN), short-term working memory (WM), and nonverbal reasoning), including age and orthographies as moderators. We found an age-by-orthography interaction effect in word reading accuracy and a significant effect of age in pseudoword reading accuracy, but we found no effect of age and orthographic depth on the fluency parameters. These results suggest that reading speed is a reliable index for discriminating between DD and control groups across European orthographies from childhood to adulthood. A similar pattern of results emerged for PA, RAN, and short-term/WM. Our findings are discussed in relation to their impact on clinical practice while considering the orthographic depth and developmental level.
