The expanded simple view of reading (SVR) model suggests that word decoding, language comprehension and executive functions are necessary for reading comprehension. Children with reading difficulties (RDs) often have deficits in critical components of reading established in the expanded SVR model and alterations in brain function of reading-related regions. Maternal education could provide children with advantageous educational opportunities or resources that support reading acquisition. The primary goal of this study was to examine the contributions of maternal education to the behavioural and neurobiological correlates of the expanded SVR model. Seventy-two 8- to 12-year-old children with RDs and typical readers (TRs) completed reading, behavioural and an functional magnetic resonance imaging stories-listening task to determine the functional connectivity of the receptive language network to the whole brain in association with maternal education. Higher maternal education was associated with better vocabulary in children with RDs and positive functional connectivity between the receptive language network and regions related to visual processing in children with RDs versus TRs. These data suggest that maternal education supports the ability to comprehend oral language and engagement of neural networks that support imagination/visualization in children with RDs.
扩展后的简单阅读观（SVR）模型表明，单词解码、语言理解和执行功能对于阅读理解是必要的。阅读困难（RD）儿童在扩展 SVR 模型中建立的阅读关键组成部分往往存在缺陷，以及与阅读相关区域的大脑功能改变。母亲的教育可以为孩子提供有利的教育机会或资源，支持阅读的习得。本研究的主要目标是探讨母亲教育对扩展 SVR 模型的行为和神经生物学相关性的贡献。72 名 8 至 12 岁的 RD 儿童和典型阅读者（TRs）完成了阅读、行为和功能磁共振成像故事听任务，以确定接受性语言网络与整个大脑的功能连接与母亲教育的关系。较高的母亲教育与 RD 儿童的词汇量较好有关，与 RD 儿童与 TRs 相比，接受性语言网络与与视觉处理相关的区域之间存在积极的功能连接。这些数据表明，母亲教育支持 RD 儿童理解口头语言的能力和支持想象力/可视化的神经网络的参与。
