在阅读和听力中，研究了正常和快速理解熟悉和不熟悉主题的说明文的大脑活动。目的是确定大脑活动及其反映的理解过程是如何被理解速度和主题熟悉程度所调节的。关于更熟悉的主题的文章不同地激活了前颞叶和内侧额回的一组区域，这些区域通常与文本水平的整合过程有关，我们认为这反映了先前知识与文章内容的整合。以更快的速度呈现的段落导致与策略和工作记忆过程（以及视觉或听觉相关区域）相关的额叶区域网络的更多激活，我们解释这反映了短暂可用的段落之间局部一致性的维持。本研究的意义在于展示文本理解的大脑系统如何适应不同的感知和知识条件。
Brain activation associated with normal and speeded comprehension of expository texts on familiar and unfamiliar topics was investigated in reading and listening. The goal was to determine how brain activation and the comprehension processes it reflects are modulated by comprehension speed and topic familiarity. Passages on more familiar topics differentially activated a set of areas in the anterior temporal lobe and medial frontal gyrus, areas often associated with text-level integration processes, which we interpret to reflect integration of previous knowledge with the passage content. Passages presented at the faster presentation resulted in more activation of a network of frontal areas associated with strategic and working-memory processes (as well as visual or auditory sensory-related regions), which we interpret to reflect maintenance of local coherence among briefly available passage segments. The implications of this research is to demonstrate how the brain system for text comprehension adapts to varying perceptual and knowledge conditions.
