中文摘要：
运用事件相关脑电位（ERP）技术,采用快速掩蔽启动范式和Go/Nogo范式,探讨汉语词汇识别过程中语音激活的时间进程和语音信息对词汇加工的影响作用.结果发现,在词汇加工的早期阶段,语音对正字法的加工没有显著影响,正字法加工诱发了明显的N250成分;语音信息的激活发生在语义信息激活之前,语音信息促进了语义信息的加工.
英文摘要：
Using the event related brain potential（ERP） technology,and combined the rapid masked priming paradigm and Go/Nogo paradigm,the time course of phonological activation and its role of the Chinese characters recognition were investigated.The results showed that,in the early stages of word processing,the phonology has no significant influence on the orthographic processing,the orthographic priming caused significant N 250 component.Before the semantic activated,the phonological information has already been activating,and which facilitates the semantic activation.
