Seven children with dyslexia and/or dysgraphia (2 girls, 5 boys, =11 years) completed fMRI connectivity scans before and after twelve weekly computerized lessons in strategies for reading source material, taking notes, and writing summaries by touch typing or groovy pencils. During brain scanning they completed two reading comprehension tasks-one involving single sentences and one involving multiple sentences. From before to after intervention, fMRI connectivity magnitude changed significantly during sentence level reading comprehension (from right angular gyrus→right Broca's) and during text level reading comprehension (from right angular gyrus→cingulate). Proportions of ideas units in children's writing compared to idea units in source texts did not differ across combinations of reading-writing tasks and modes. Yet, for handwriting/notes, correlations insignificant before the lessons became significant after the strategy instruction between proportion of idea units and brain connectivity at all levels of language in reading comprehension (word-, sentence-, and text) during scanning; but for handwriting/summaries, touch typing/notes, and touch typing/summaries changes in those correlations from insignificant to significant after strategy instruction occurred only at text level reading comprehension during scanning. Thus, handwriting during note-taking may benefit all levels of language during reading comprehension, whereas all other combinations of modes and writing tasks in this exploratory study appear to benefit only the text level of reading comprehension. Neurological and educational significance of the interdisciplinary research findings for integrating reading and writing and future research directions are discussed.
七名患有诵读困难和/或书写困难的儿童(2名女孩,5名男孩,平均年龄11岁)在接受了为期十二周的关于阅读源材料、做笔记以及通过触摸打字或使用特制铅笔撰写总结的策略的计算机课程前后,完成了功能磁共振成像(fMRI)连接性扫描。在脑部扫描期间,他们完成了两项阅读理解任务——一项涉及单个句子,另一项涉及多个句子。从干预前到干预后,在句子层面阅读理解(从右角回→右布洛卡区)和文本层面阅读理解(从右角回→扣带回)过程中,fMRI连接强度发生了显著变化。儿童写作中的观点单元比例与源文本中的观点单元比例相比,在阅读-写作任务和模式的组合中并无差异。然而,对于手写笔记,课程前不显著的相关性在策略指导后,扫描期间阅读理解(单词、句子和文本)所有语言层面的观点单元比例与大脑连接性之间变得显著;但对于手写总结、触摸打字笔记和触摸打字总结,策略指导后这些相关性从无显著变化到显著变化仅发生在扫描期间的文本层面阅读理解中。因此,做笔记时的手写可能在阅读理解过程中对所有语言层面都有益,而在这项探索性研究中,所有其他模式和写作任务的组合似乎仅对文本层面的阅读理解有益。讨论了跨学科研究结果对于整合阅读与写作的神经学和教育学意义以及未来的研究方向。
