Abstract

Abstract This study investigated the triple-deficit hypothesis in Arabic, a Semitic transparent orthography, among 258 native Arabic children from Grade 3, divided into a typical readers group (n = 204) and a dyslexia group (n = 54). Children were tested on word- and pseudoword-reading accuracy, word-reading fluency, phonological awareness (PA), naming speed (NS), orthographic processing (OP), and nonverbal reasoning ability. The results indicated that all children with dyslexia had either double or triple deficits, and none of them had a single deficit. Children with triple deficits showed lower performance than children with single and no deficits on all the reading measures. They have also lower performance to children with double deficits on word-reading accuracy but comparable scores in word- and pseudoword-reading fluency. In addition, OP was confirmed as an additional independent predictor of word-level reading skills besides PA and NS, while controlling for age and nonverbal intelligence. The classification findings showed that the presence of a triple deficit maximizes the risk of reading failure. These findings support the additive nature of combined deficits in PA, NS, and OP. Moreover, they establish the benefit of including OP as a third deficit, in addition to PA and NS, underlying dyslexia in Arabic.

阿拉伯语的三重缺陷假说:来自有和没有阅读障碍儿童的证据

摘要本研究调查了258名来自三年级的阿拉伯母语儿童的阿拉伯语（一种闪米特语透明正写法）中的三重缺失假说，他们被分为典型读者组（n=204）和阅读障碍组（n=54）。测试了儿童的单词和假名阅读准确性、单词阅读流畅性、语音意识（PA）、命名速度（NS）、正字法处理（OP）和非语言推理能力。结果表明，所有患有阅读障碍的儿童都有双重或三重缺陷，没有一个有单一缺陷。三重缺陷儿童在所有阅读指标上的表现都低于单一和无缺陷儿童。与单词阅读准确性双重缺陷但单词和假名阅读流利性得分相当的儿童相比，他们的表现也较低。此外，OP被证实是除PA和NS之外的单词水平阅读技能的额外独立预测因子，同时控制了年龄和非语言智力。分类结果表明，三重缺陷的存在使阅读失败的风险最大化。这些发现支持了PA、NS和OP合并缺陷的相加性质。此外，它们确定了将OP作为除PA和NS之外的第三种缺陷的益处，这是阿拉伯语中潜在的阅读障碍。
