流利的读者快速准确地处理书面文本，并理解他们所读的内容。从历史上看，阅读流畅性一直被建模为离散技能的产物，如单个单词解码。最近的概念强调，流利的阅读是能力的产物，并协调，多个认知子技能（多成分的观点）。在这项研究中，我们研究了如何激活模式的核心阅读区域的变化，流利的阅读能力是通过阅读速度操纵。我们评估了13名右利手的成年人与一个新的功能磁共振成像任务评估流畅的句子阅读和低阶字母阅读在每个参与者的正常流畅阅读速度，以及限制（减慢）和加速阅读速度。比较流畅的阅读条件下，休息显示区域，包括双侧枕梭状，左中颞，额下回集群跨阅读速度。通过与字母阅读任务的比较，显示了这些区域对流畅句子阅读反应的选择性。感兴趣区域分析表明，在限制和加速的速度，这些地区的反应显着更流畅的句子阅读。重要的是，随着阅读速度的增加，与阅读相关的一个区域的激活增加：枕叶/梭状皮质（左>右）。这些结果表明，虽然从事阅读的大脑区域在流畅的阅读过程中有选择性地做出反应，但这些区域在流畅阅读的能力被操纵时做出不同的反应。我们的理解阅读流畅性，阅读发展，和阅读障碍的影响进行了讨论。
Fluent readers process written text rapidly and accurately, and comprehend what they read. Historically, reading fluency has been modeled as the product of discrete skills such as single word decoding. More recent conceptualizations emphasize that fluent reading is the product of competency in, and the coordination of, multiple cognitive sub-skills (a multi-componential view). In this study, we examined how the pattern of activation in core reading regions changes as the ability to read fluently is manipulated through reading speed. We evaluated 13 right-handed adults with a novel fMRI task assessing fluent sentence reading and lower-order letter reading at each participant’s normal fluent reading speed, as well as constrained (slowed) and accelerated reading speeds. Comparing fluent reading conditions with rest revealed regions including bilateral occipito-fusiform, left middle temporal, and inferior frontal gyral clusters across reading speeds. The selectivity of these regions’ responses to fluent sentence reading was shown by comparison with the letter reading task. Region of interest analyses showed that at constrained and accelerated speeds these regions responded significantly more to fluent sentence reading. Critically, as reading speed increased, activation increased in a single reading-related region: occipital/fusiform cortex (left > right). These results demonstrate that while brain regions engaged in reading respond selectively during fluent reading, these regions respond differently as the ability to read fluently is manipulated. Implications for our understanding of reading fluency, reading development, and reading disorders are discussed.
