| 摘 要： | 目的考察汉字语义加工的脑区以及早期皮层电位特征。方法选取15名被试者,采用语义判断的实验范式,运用64导事件相关电位设备采集脑电,以汉语中无语义汉字和有语义汉字为实验材料考察语义加工的早期皮层电位。实验为重复测量设计。结果脑电数据结果显示有语义汉字比无语义汉字诱发了更大的N1成分,分布在左脑枕顶区。结论汉字的语义加工开始于150 ms左右的左枕顶区的N1这一早期皮层电位。

| Abstract: | Objective To investigate the early potentials of Chinese Characters' semantic processing.Methods Scalp EEG(64 channels) signals were recorded in 15 healthy university students who were asked to decide an semantic task through a repeated measures design.Results ERP data show that meaningful Chinese Characters elicted more negtive occipital-parietal N1 than non-meaningful Chinese Characters.Conclusion Chinese Characters' semantic processing occurs left occipital-parietal N1 about 150 ms. |
