ABSTRACT Background Neglect dyslexia (ND) is a reading disorder that impairs the left visual field. The Left periphery (LP) is the highest layer of the extended syntactic structure, and it represents the interface between communicative intention and syntactic realization. Topic and Focus are the two central projections of the LP. Sentences involving either Topic or Focus display marked structures in which a constituent, extracted from its original position, is fronted. Aims The aim of the present study is to test whether sentences containing Topic or Focus display a facilitation effect with respect to canonical word order (SVO) sentences in the reading performance of individuals with neglect dyslexia. Methods & Procedures Nine participants with neglect dyslexia were tested in a reading task. Participants were asked to read aloud a list of 103 sentences, classified into Condition 1 (experimental condition) and Condition 2 (control condition) based on their syntactic structure. Both substitutions and omissions of letters, syllables, and words were considered as errors. Data were analysed using generalized linear mixed model (GLMM)with accuracy as the dependent variable, condition as independent variable and subjects and sentences as random intercepts. Outcomes & Results Results showed that sentences containing Topic and Focus were read with significantly less impairment than control sentences (t (100) = −2.06, p = 0.041). Conclusions Our findings are consistent with previous studies on the effects of syntax in ND as they demonstrate that sentence structure has a crucial influence on driving attention in individuals with ND.

忽视阅读障碍的左外周

摘要 背景 忽视阅读障碍 (ND) 是一种阅读障碍，会损害左视野。左边缘（LP）是扩展句法结构的最高层，它代表交际意图和句法实现之间的接口。Topic 和 Focus 是 LP 的两个中心投影。涉及主题或焦点的句子显示标记结构，其中从原始位置提取的成分位于前面。目的 本研究的目的是测试包含 Topic 或 Focus 的句子是否对规范词序 (SVO) 句子在忽视阅读障碍患者的阅读表现中显示出促进作用。方法和程序 九名患有忽视阅读障碍的参与者接受了阅读任务的测试。参与者被要求大声朗读 103 个句子，根据句法结构分为条件 1（实验条件）和条件 2（控制条件）。字母、音节和单词的替换和省略均被视为错误。数据采用广义线性混合模型（GLMM）进行分析，精度为因变量，条件为自变量，主语和句子为随机截距。结果与结果 结果表明，与对照句子相比，包含主题和焦点的句子在阅读时的损伤显着减少（t (100) = -2.06, p = 0.041）。结论我们的发现与先前关于 ND 中句法影响的研究一致，因为它们表明句子结构对 ND 个体的注意力驱动具有至关重要的影响。根据句法结构分为条件 1（实验条件）和条件 2（控制条件）。字母、音节和单词的替换和省略均被视为错误。数据采用广义线性混合模型（GLMM）进行分析，精度为因变量，条件为自变量，主语和句子为随机截距。结果与结果 结果表明，与对照句子相比，包含主题和焦点的句子在阅读时的损伤显着减少（t (100) = -2.06, p = 0.041）。结论我们的发现与先前关于 ND 中句法影响的研究一致，因为它们表明句子结构对 ND 个体的注意力驱动具有至关重要的影响。根据句法结构分为条件 1（实验条件）和条件 2（控制条件）。字母、音节和单词的替换和省略均被视为错误。数据采用广义线性混合模型（GLMM）进行分析，精度为因变量，条件为自变量，主语和句子为随机截距。结果与结果 结果表明，与对照句子相比，包含主题和焦点的句子在阅读时的损伤显着减少（t (100) = -2.06, p = 0.041）。结论我们的发现与先前关于 ND 中句法影响的研究一致，因为它们表明句子结构对 ND 个体的注意力驱动具有至关重要的影响。
