Functional magnetic resonance imaging (fMRI) was used to investigate the impact of literacy skills in young adults on the distribution of cerebral activity during comprehension of sentences in spoken and printed form. The aim was to discover where speech and print streams merge, and whether their convergence is affected by the level of reading skill. The results from different analyses all point to the conclusion that neural integration of sentence processing across speech and print varies positively with the reader's skill. Further, they identify the inferior frontal region as the principal site of speech–print integration and a major focus of reading comprehension differences. The findings provide new evidence of the role of the inferior frontal region in supporting supramodal systems of linguistic representation.

阅读差异与大脑：句子处理中语音和文字的皮层整合因阅读者技能而异

使用功能磁共振成像 (fMRI) 来研究年轻人的识字技能在理解口语和印刷形式的句子期间对大脑活动分布的影响。目的是发现语音流和印刷流在哪里融合，以及它们的融合是否受到阅读技能水平的影响。不同分析的结果都表明，通过语音和文字处理句子的神经整合会随着读者的技能而积极变化。此外，他们将下额叶区域确定为语音-印刷整合的主要部位，也是阅读理解差异的主要焦点。这些发现为下额叶区域在支持超模态语言表征系统中的作用提供了新的证据。
