Abstract This study examines ERP correlates of the different processes associating two phones to one vs. two phonemic categories in two regional varieties of French. Two groups of French listeners are compared, respectively exploiting two regional varieties, with a contrast between the mid-low /ϵ/ and the mid-high /e/ for Northern French (NF) but not for Southern French (SF). It is expected that the competition between the two close categories /e/ vs. /ϵ/ in NF could induce an ERP modulation in the processing of/ϵ/compared to a phoneme/a/with no close competitor, serving as control. In contrast, there should be no difference in ERP response in /ϵ/ vs. /a/ in SF, where there is no competition between the close neighbors /e/ and /ϵ/. The participants of the two groups listened to words containing either /ϵ/ or /a/ in a go/no-go semantic categorization task in which the critical /ϵ/ and /a/ words did not require an overt behavioral response. We found a significant difference in the N400 amplitude between the two conditions in the NF but not in the SF variety. The fact that the ERP modulations appear on the N400 component suggests that lexical access is influenced by the regional variety of the speakers.

将元音映射到法语的两个区域变体中的音素类别：一项 ERP 研究

摘要 本研究检查了在法语的两个区域变体中将两个音素与一个或两个音素类别相关联的不同过程的 ERP 相关性。比较两组法国听众，分别利用两个区域变体，中低音 /ϵ/ 和中高音 /e/ 之间的对比针对法国北部 (NF) 而不是南部法国 (SF)。与作为对照的音素/a/相比，NF 中两个接近类别 /e/ 与 /ϵ/ 之间的竞争可以在 /ϵ/ 的处理中引起 ERP 调制。相比之下，SF 中 /ϵ/ 与 /a/ 中的 ERP 响应应该没有差异，其中近邻 /e/ 和 /ϵ/ 之间没有竞争。两组的参与者在 go/no-go 语义分类任务中聆听包含 /ϵ/ 或 /a/ 的单词，其中关键的 /ϵ/ 和 /a/ 单词不需要明显的行为反应。我们发现 NF 中两种条件之间的 N400 振幅存在显着差异，但在 SF 品种中则没有。ERP 调制出现在 N400 组件上的事实表明词汇访问受到说话者区域多样性的影响。
