叙事理解是一种比阅读活动更直观的围产期语言能力。是否有特定的共同的大脑区域负责叙事理解和阅读，甚至在获得阅读之前就调整到阅读熟练程度，这是当前研究的问题。我们在儿童5-7岁（k -2年级）和11岁（5-7年级）两个年龄点的叙事理解任务中获得了功能磁共振成像数据。然后，我们检查了这些功能磁共振成像数据与这些孩子11岁时阅读和阅读理解得分之间的相关性。研究发现，5-7岁儿童在叙事理解过程中额叶和上边缘回（ba40）的激活程度越高，其11岁时的单词阅读和阅读理解得分越高。当将他们11岁时的叙事理解功能数据与同一年龄点的阅读分数相关联时，发现了颞部和枕部激活的转变。我们认为，在阅读前听故事时，对执行功能和视听网络的依赖增加，有助于老年阅读能力的提高，并可能是未来阅读能力的生物标志物。在11岁时，依靠想象力/可视化和听觉处理来理解叙事的儿童也表现出更强的阅读能力。理解支持听觉叙事和阅读理解的协调神经通路可能为开发有效的阅读干预程序工具提供指导。Elsevier Ltd.出版。
Narrative comprehension is a perinatal linguistic ability which is more intuitive than reading activity. Whether there are specific shared brain regions for narrative comprehension and reading that are tuned to reading proficiency, even before reading is acquired, is the question of the current study. We acquired fMRI data during a narrative comprehension task at two age points, when children are age 5-7 (K-2nd grade) and later when the same children were age 11 (5th-7th grade). We then examined correlations between this fMRI data and reading and reading comprehension scores from the same children at age 11. We found that greater frontal and supramarginal gyrus (BA 40) activation in narrative comprehension at the age of 5-7 years old was associated with better word reading and reading comprehension scores at the age of 11. A shift towards temporal and occipital activation was found when correlating their narrative comprehension functional data at age 11, with reading scores at the same age point. We suggest that increased reliance on executive functions and auditory-visual networks when listening to stories before reading is acquired, facilitates reading proficiency in older age and may be a biomarker for future reading ability. Children, who rely on use of imagination/visualization as well as auditory processing for narrative comprehension when they reach age 11, also show greater reading abilities. Understanding concordant neural pathways supporting auditory narrative and reading comprehension might be guide for development of effective tools for reading intervention programs.
