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.
功能磁共振成像（fMRI）被用于研究年轻人的读写能力对口语和书面形式句子理解过程中大脑活动分布的影响。目的是发现语音和文字信息流在何处融合，以及它们的融合是否受阅读技能水平的影响。不同分析的结果均指向这样一个结论：跨语音和文字的句子处理的神经整合与读者的技能呈正相关。此外，研究还确定了额下回区域是语音-文字整合的主要部位，也是阅读理解差异的主要焦点。这些发现为额下回区域在支持语言表征的超模态系统中所起的作用提供了新证据。
