先前的研究表明，即使精通双语的人只用一种语言完成任务，跨语言激活也会出现。本研究采用带有事件相关电位（ERPs）的图-词干扰范式研究了第二语言（L2）单词生成过程中跨语言激活的时间过程。生活在第二语言环境中的西班牙-英语双语者在他们的第二语言英语中命名图片，而忽略了与图片一起视觉呈现的第二语言英语干扰词。当干扰物与图片的英文名称或西班牙语名称在语义上或语音上相关时，参与者说出图片的速度要比当图片和干扰词不相关时慢。N2峰的平均幅值（200 ~ 260 ms）和N3峰的平均幅值（350 ~ 400 ms）也存在干扰。结果表明，在以二语为主导的语境中，两种语言的词汇选择在二语言语规划过程中相互竞争。(C) 2010 Elsevier B.V.版权所有
Previous research has demonstrated that cross-language activation is present even when proficient bilinguals perform a task only in one language. The present study investigated the time-course of cross-language activation during word production in a second language (L2) by using a picture-word interference paradigm with event-related potentials (ERPs). Spanish-English bilinguals living in an L2 environment named pictures in their L2 English while ignoring L2 English distractor words that were visually presented with the pictures. Participants named pictures more slowly when distractors were semantically related or phonologically related to either the English name of the picture or the Spanish name of the picture than when picture and distractor word were unrelated. Interference was also detectable in the mean amplitude of the N2 peak (200-260 ms) and the N3 range (350-400 ms). The results suggest that lexical alternatives from both languages compete for selection in the process of L2 speech planning in a predominantly L2 context. (C) 2010 Elsevier B.V. All rights reserved.
