The expanded Simple View of Reading model suggests language processing and word reading as contributors to reading comprehension and points at the participation of executive functions as supporting these abilities. Switching and inhibition are both executive functions (EF) contributing to reading, especially in languages with two writing systems-shallow and deep, such as Hebrew. Here, we aimed to determine the specific role of switching/inhibition both cognitively and neurobiologically in the Simple View of Reading model among 49 eight- to 12-year-old Hebrew-speaking children. Children underwent reading and cognitive behavioural testing as well as a five-min resting-state fMRI scan. Functional connectivity of the fronto-parietal network related to switching/inhibition was determined and included in a moderation model. Results suggest that both switching/inhibition abilities and functional connectivity within the fronto-parietal network moderate the relations between word reading and reading comprehension. This strengthens the contribution of switching/inhibition to facilitating reading comprehension and supports the need to include it as part of the expanded SVR model.
扩展的阅读简单模型表明，语言处理和单词阅读有助于阅读理解，并指出执行功能的参与支持了这些能力。转换和抑制都是有助于阅读的执行功能，特别是在像希伯来语这样具有浅层和深层两种书写系统的语言中。在这里，我们旨在确定49名8至12岁说希伯来语的儿童在阅读简单模型中，转换/抑制在认知和神经生物学方面的具体作用。孩子们接受了阅读和认知行为测试，以及五分钟的静息态功能磁共振成像扫描。确定了与转换/抑制相关的额顶叶网络的功能连接，并将其纳入一个调节模型。结果表明，转换/抑制能力和额顶叶网络内的功能连接都调节了单词阅读和阅读理解之间的关系。这加强了转换/抑制对促进阅读理解的贡献，并支持将其作为扩展的简单阅读模型的一部分。
