文字加工是一项重要的认知技能，在当代社会受到高度重视和努力培养。本研究采用竞争范式，考察了汉字与面孔、汉字与房屋之间不同关系在早期视觉加工过程中的电生理相关性。我们观察到，可识别的汉字竞争主要与面孔，而不是房子在早期的视觉加工阶段，与N170显着减少面孔，但不是房子，当他们被视为同时与可识别的字符相对于当他们被视为同时与不可识别的字符。与我们以前的研究一致，汉字学习后N170显著增加，表明汉字识别水平对N170振幅有调节作用。此外，我们还发现，与房屋相比，N170对人脸的反应更大，这表明在早期视觉处理阶段，处理人脸和房屋的神经机制是不同的。
Character processing is a crucial cognitive skill that is highly emphasized and industriously cultivated in contemporary society. In the present study, using a competition paradigm, we examined the electrophysiological correlates of different relationships between Chinese characters and faces and between Chinese characters and houses during early visual processing. We observed that identifiable Chinese characters compete primarily with faces rather than houses at an early visual processing stage, with a significantly reduced N170 for faces but not for houses, when they were viewed concurrently with identifiable characters relative to when they were viewed concurrently with unidentifiable characters. Consistent with our previous study, there was a significant increase in N170 after characters have been learned, indicating a modulatory effect of Chinese character identification level on N170 amplitude. Furthermore, we found an enlarged N170 in response to faces compared to houses, indicating that the neural mechanisms for processing faces and houses are different at an early visual processing stage.
