Abstract

Phoneme discrimination is believed to be less accurate in non-native languages compared to native ones. What remains unclear is whether differences in pre-attentive phonological processing emerge between the first foreign language (L2) and additional ones (L3/Ln), and whether they might be influenced by the acquisition setting (formal vs. naturalistic). We conducted an event-related brain potential oddball study with native Polish learners of English (L2) and Norwegian (L3/Ln). The results revealed a graded amplitude of the mismatch negativity (MMN) effect, which was largest in L1, smaller in L2, and smallest in L3/Ln. Considering the previously obtained results for naturalistic/mixed learners with the same language combination, we believe that the acquisition setting is an important factor influencing the perception of phonemic contrasts. In the naturalistic group, no difference was observed between L1 and L2, while the instructed group exhibited more fine-grained distinctions between all tested languages.

L2/L3 学习者音位对比感知的神经生理学：学习环境的作用

人们认为，与母语相比，非母语语言的音素辨别准确性较低。目前尚不清楚的是，第一外语（L2）和第二外语（L3/Ln）之间是否会出现注意前语音处理的差异，以及这些差异是否会受到学习环境（正式环境和自然环境）的影响。我们对母语为波兰语的英语（L2）和挪威语（L3/Ln）学习者进行了一项与事件相关的脑电位奇数研究。研究结果显示，错配负性（MMN）效应的振幅是分级的，L1级最大，L2级较小，L3/Ln级最小。考虑到之前在自然学习者/混合学习者中获得的相同语言组合的结果，我们认为学习环境是影响音位对比感知的一个重要因素。在自然学习组中，L1 和 L2 之间没有差异，而在指导学习组中，所有测试语言之间的差异更为细微。
