本研究的目的是探讨长期暴露在二语环境中的高水平二语学习者在二语形态句法加工过程中的电生理学相关性。本研究收集了22名英语-西班牙语习得者在阅读第一语言中存在或不存在的二语形态句法特征(数字和性别一致)的句子时的事件相关电位。年龄匹配的母语为西班牙语的控制组受试者的结果包括LAN型早期否定的ERP模式，然后是对违反协议和对两个句子位置的反应的P600效应。第二语言习得者的测试结果与此类似，在第一个句子位置(短语内违反)出现了早期否定，随后出现了P600，而在第二个句子位置(跨阶段违反)只出现了P600效应，并且在两个句子位置上的波幅和起始潜伏期在性别和数量上存在显著差异。这些结果表明，高水平学习者在二语加工过程中可以表现出与本族语者相似的电生理相关，但也表明了习得年龄和从第一语言到第二语言的迁移过程等因素的影响。
The goal of the present study was to investigate the electrophysiological correlates of second-language (L2) morphosyntactic processing in highly proficient late learners of an L2 with long exposure to the L2 environment. ERPs were collected from 22 English-Spanish late learners while they read sentences in which morphosyntactic features of the L2 present or not present in the first language (number and gender agreement, respectively) were manipulated at two different sentence positions-within and across phrases. The results for a control group of age-matched native-speaker Spanish participants included an ERP pattern of LAN-type early negativity followed by P600 effect in response to both agreement violations and for both sentence positions. The late L2 learner results included a similar pattern, consisting of early negativity followed by P600, in the first sentence position (within-phrase agreement violations) but only P600 effects in the second sentence position (across-phrase agreement violation), as well as significant amplitude and onset latency differences between the gender and the number violation effects in both sentence positions. These results reveal that highly proficient learners can show electrophysiological correlates during L2 processing that are qualitatively similar to those of native speakers, but the results also indicate the contribution of factors such as age of acquisition and transfer processes from first language to L2.
