This article reports two different studies examining the theoretical account of low-level deficits in beat perception as an alternative explanation of developmental dyslexia in Greek, an orthographically consistent language. Study I examined the relationship of amplitude rise time and frequency discrimination with measures of phonological processing, working memory, and reading fluency in a large unselected sample of Grade 4 children. Study II examined the presence of beat perception deficits in groups of Grade 2, 4, and 6 children with dyslexia and their chronological age controls. The results provided no evidence to support meaningful associations between beat perception tasks and reading or the theoretical account of beat perception deficits as a sufficient explanation or contributing factor to dyslexia. Implications on the importance of auditory processing in reading in orthographically consistent languages are discussed.
本文报告了两项不同的研究，旨在检验音高感知的低级缺陷理论解释作为希腊语发展性阅读障碍的替代解释，希腊语是一种拼写上一致的语言。研究一检验了在一个大的未选择的四年级儿童样本中，幅度上升时间和频率辨别与语音处理、工作记忆和阅读流畅性的测量之间的关系。研究二检验了阅读障碍儿童和他们的年龄匹配对照组在二年级、四年级和六年级的音高感知缺陷的存在情况。结果没有提供支持音高感知任务与阅读之间有意义关联的证据，也没有支持音高感知缺陷理论解释作为阅读障碍的充分解释或促成因素的证据。本文还讨论了在拼写上一致的语言中，听觉处理在阅读中的重要性。
