我们研究了这样的假设：学习书写汉字会影响大脑的汉字阅读网络。大学语文班学生在汉字书写条件下学习了30个汉字，在拼音书写条件下学习了30个汉字。学习后，被动观看时收集的功能磁共振成像显示了阅读汉字和英文单词的不同网络，表明通过短期学习适应新书写系统的需求。除了这些预期的差异之外，我们还发现，在词汇决策和隐性写作任务中，汉字书写对双侧顶叶上小叶和双侧舌回的更大激活（相对于拼音书写）有特定的影响。这些发现表明，字符书写建立了字符及其正字法的视觉空间结构的更高质量的表示。我们发现，在词汇决策任务中，与拼音书写训练的字符相比，双侧感觉运动皮层（SMC）更多地参与汉字书写训练的字符，这表明边干边学在字符识别过程中会引发与感觉运动信息的更多交互。此外，我们发现识别准确度与右顶上小叶、右舌回和左侧 SMC 的激活存在相关性，表明这些区域支持汉字书写对阅读的促进作用。最后，与之前的行为研究一致，我们发现汉字书写训练通过在双侧颞中回产生更大的激活来促进与语义的联系，而拼音书写训练通过在右额下回产生更大的激活来促进与音系的联系。 Hum Brain Mapp，2013。(c) 2012 Wiley periodicals, Inc.
We examined the hypothesis that learning to write Chinese characters influences the brain's reading network for characters. Students from a college Chinese class learned 30 characters in a character-writing condition and 30 characters in a pinyin-writing condition. After learning, functional magnetic resonance imaging collected during passive viewing showed different networks for reading Chinese characters and English words, suggesting accommodation to the demands of the new writing system through short-term learning. Beyond these expected differences, we found specific effects of character writing in greater activation (relative to pinyin writing) in bilateral superior parietal lobules and bilateral lingual gyri in both a lexical decision and an implicit writing task. These findings suggest that character writing establishes a higher quality representation of the visual-spatial structure of the character and its orthography. We found a greater involvement of bilateral sensori-motor cortex (SMC) for character-writing trained characters than pinyin-writing trained characters in the lexical decision task, suggesting that learning by doing invokes greater interaction with sensori-motor information during character recognition. Furthermore, we found a correlation of recognition accuracy with activation in right superior parietal lobule, right lingual gyrus, and left SMC, suggesting that these areas support the facilitative effect character writing has on reading. Finally, consistent with previous behavioral studies, we found character-writing training facilitates connections with semantics by producing greater activation in bilateral middle temporal gyri, whereas pinyin-writing training facilitates connections with phonology by producing greater activation in right inferior frontal gyrus.
