采用ERP技术，考察听觉条件下汉语音段与超音段信息在注意加工阶段的时间进程， LORETA源定位分析比较二者的脑激活模式。研究结果为：（1）行为学结果显示，声母和声调的改变所带来的任务难度更大，暗示在语义激活过程中所起的作用也更大，同时也说明声调加工占用了更多的心理资源，工作记忆的时长更长。（2）EEG结果显示，听觉条件下，汉语音段与超音段信息在注意阶段对语义加工有着相似的作用和时间进程。（3）LORETA 源定位分析结果显示，在汉语句子加工中，虽然左半球占有一定的优势，但右半球也有所参与，在汉语语义整合阶段，需要大脑两半球的协同合作，对语义加工中大脑偏侧化的结论提出了质疑。

Based on the past researches and experimental studies on the spoken words of Chinese and alpha‐betic writing system ,this study was conducted to investigate the time course and the brain activation of Chinese segmental and supra‐segmental information in auditory situation by using ERP technique ,and ana‐lyze the intensity of neural activation’s source in the human brain by using LORETA .The results are:(1) The change of the initial consonant and tone brings more difficult tasks ;implication plays bigger role in se‐mantic activation ,w hich show s tonal processing uses more psychological resources ,w hich causes long du‐ration of working memory .(2) EEG result shows in auditory situation Chinese segmental and supra‐seg‐mental information have similar function and time course in semantic processing in attentive stage . (3) Chinese sentence processing took place mainly in the left hemisphere ;however ,the right hemisphere was involved in this process as well ,and both of the left and the right hemisphere got involved in the analysis of the semantic information at attentive processing stage .This result therefore raised a reasonable doubt about cerebral hemisphere processing lateralization w hile processing the Chinese semantic information .
