书写系统如何代表语言的差异提出了一个重要的问题，即是否存在一个跨语言阅读的通用功能架构。为了研究支持阅读技能的神经网络中潜在的语言差异，我们收集了两个阅读任务中字母（英语）和形态音节（汉语）书写系统的读者的fMRI数据。在一个实验中，参与者在接近自然阅读的条件下阅读短篇小说，而在另一个实验中，参与者决定个体刺激是否是真实的单词。以往的研究大多采用元语言任务来比较这两种书写系统，普遍支持这样一个结论：对于熟练的中文和英文读者来说，阅读系统的组织方式是不同的。我们观察到阅读网络中的语言差异在很大程度上取决于任务。在词汇判断中，汉语的额中回（MFG）和右侧梭状回（rFFG）比英语的活跃，而英语的颞后沟比汉语的活跃。我们发现了一个非常不同的模式的语言效果在自然的阅读范例，在此期间，显着的差异，只观察到在视觉区域通常不被认为是特定的阅读网络，和颞中回，这被认为是重要的直接映射的正字法语义。事实上，在经常被讨论为支持两种语言之间不同的认知或语言功能的领域，我们观察到了互动。具体来说，语言差异最明显的MFG和rFFG在词汇决策任务，而没有语言差异，在这些领域观察到在沉默阅读的文本理解。
Differences in how writing systems represent language raise important questions about whether there could be a universal functional architecture for reading across languages. In order to study potential language differences in the neural networks that support reading skill, we collected fMRI data from readers of alphabetic (English) and morpho-syllabic (Chinese) writing systems during two reading tasks. In one, participants read short stories under conditions that approximate natural reading, and in the other, participants decided whether individual stimuli were real words or not. Prior work comparing these two writing systems has overwhelmingly used meta-linguistic tasks, generally supporting the conclusion that the reading system is organized differently for skilled readers of Chinese and English. We observed that language differences in the reading network were greatly dependent on task. In lexical decision, a pattern consistent with prior research was observed in which the Middle Frontal Gyrus (MFG) and right Fusiform Gyrus (rFFG) were more active for Chinese than for English, whereas the posterior temporal sulcus was more active for English than for Chinese. We found a very different pattern of language effects in a naturalistic reading paradigm, during which significant differences were only observed in visual regions not typically considered specific to the reading network, and the middle temporal gyrus, which is thought to be important for direct mapping of orthography to semantics. Indeed, in areas that are often discussed as supporting distinct cognitive or linguistic functions between the two languages, we observed interaction. Specifically, language differences were most pronounced in MFG and rFFG during the lexical decision task, whereas no language differences were observed in these areas during silent reading of text for comprehension.
