摘　　要：从汉语词汇的听觉加工入手,利用汉语不同于非声调语言的特点,通过变化词汇的元音、辅音和声调考察这三类语音信息在汉语词汇语义激活中的作用。采用ERP方法,结合LORETA源定位技术,通过被动的oddball范式,考察在早期自动加工过程中。Chinese is a tone language, in which both lexical tone and intonation is signaled by pitch variation and associated with spectral processing. In the research, we aim at investigating the role of phonological on the activation of lexical meanings in an early pre-attentive stage and the neural mechanisms, through changing vowel, consonant and tone. Here we combine event-related potential recordings and source estimation （LORETA） to examine the issues as following： the role of phonological on the activation of lexical meanings and the neural mechanisms in the early automatically processing by using the passive oddball paradigm.
