双语社会中的儿童通常同时获得不同书写系统的阅读技能，这些书写系统在音-字母映射或正字法深度的一致性方面各不相同。为了研究其对儿童皮层阅读网络的影响，我们对34名同时使用印度语和英语的双语儿童在阅读单词和非单词刺激时进行了功能成像。印地语是一致的，并依赖于语音组件的刺激，英语是不一致的，这就需要词汇检索的话，但非词的语音组件。虽然儿童招募了一个共享的阅读网络的两种语言，析因分析显示刺激效应（词/非词）在双侧额叶，顶叶和左角区。随后的分析表明，刺激效果是显着的英语，其中有一个深刻的正字法，相比印地语，这是透明的。我们的研究结果提供了新的证据，正字法深度形状皮层阅读过程中的发展。(C)2015 Elsevier Inc.

Children in bilingual societies often simultaneously acquire reading skills in distinct writing systems that vary in consistency of sound-letter mapping or orthographic depth. To investigate its effect on cortical reading networks in children, we performed functional imaging on 34 simultaneous Hindi-English biliterate children as they read word and nonword stimuli. In contrast to Hindi which is consistent and relies on phonological assembly for both stimuli, English is inconsistent which necessitates lexical retrieval for words, but phonological assembly for nonwords. While children recruited a shared reading network for both languages, factorial analysis revealed stimulus effects (word/nonword) in bilateral frontal, parietal and left angular regions. Subsequent analyses showed that the stimulus effect was significant in English, which has a deep orthography, in comparison to Hindi, which is transparent. Our results provide novel evidence that orthographic depth shapes cortical reading processes during development. (C) 2015 Elsevier Inc. All rights reserved.
