摘　　要：本文采用ERP技术研究我国英语学习者在纯二语语境中加工二语词汇时的一语自动激活位点与时间进程,并基于BIA+和RHM模型提出了解释一语自动激活特点与机制的EHM(Extended Hierarchical Model)理论模型。结果发现:1)激活位点上,一语自动激活在概念层、词形层和亚词形层均有出现,即二语词汇加工伴随着多层级的一语自动激活。此外,亚词形层的激活强度存在不对称性,尾字强于首字。2)时间进程上,一语自动激活从加工早期业已存在,并且持续到晚期。二语词形首先激活概念,然后激活对应的一语词形,并且进一步在亚词形层激活一语尾字及首字。本文提出的EHM模型可较好地解释我国英语学习者在二语加工中的一语自动激活特点与机制。By using ERPs technique,this paper investigated the locus and time course of L1 automatic activation in L2 words processing in an L2-only context by Chinese EFL learners.Based on BIA+and RHM models,this paper further proposed an EHM theoretical model to account for the features and mechanism of L1 automatic activation.The findings are as follows:1)in terms of locus,L1 automatic activation took place at the conceptual,lexical and sub-lexical levels.That is to say,L2 words processing was accompanied with multi-level L1 automatic activation.In addition,the strength of activation at the sub-lexical level was asymmetric in that the activation of the final character was stronger than that of the first one.2)In terms of time course,L1 automatic activation started at the early stages during L2 processing and lasted to the late stages.The L2wordforms sequentially activated the concepts,the corresponding L1 word forms,and the final and the first character at the sub-lexical level.The EHM model proposed by this paper can better account for the features and mechanism of L1 automatic activation during L2 word processing of Chinese EFL learners.
