The development of native-like memory traces for foreign phonemes can be measured by using the Mismatch Negativity (MMN), a component of the auditory event-related potential. Previous studies have shown that the MMN is sensitive to changes in neural organization depending on language experience. Here we measured the MMN response in 5-6year-old monolingual German and bilingual Turkish-German kindergarten children growing up in Germany. MMN was investigated to a German vowel contrast and to a vowel contrast that exists in Turkish and in German. The results show that compared to a German control group, the MMN response is less robust in Turkish-German children to the German vowel contrast. The response to the contrast that exists in both languages does not differ between groups. Overall, the results suggest that the Turkish-German children have not yet fully acquired the German phonetic inventory despite living in Germany since birth and being immersed in a German-speaking environment.
母语样的记忆痕迹的发展可以通过使用失匹配负波（MMN）来衡量，这是听觉事件相关电位的一个组成部分。先前的研究表明，MMN 对外语语音的神经组织变化很敏感，这取决于语言经验。在此，我们测量了在德国长大的 5-6 岁的单语德语和双语土耳其语-德语幼儿园儿童的 MMN 反应。我们研究了 MMN 对德语元音对比和土耳其语和德语中存在的元音对比的反应。结果表明，与德语对照组相比，土耳其语-德语儿童对德语元音对比的 MMN 反应较弱。两组之间对两种语言都存在的对比的反应没有差异。总体而言，结果表明，尽管土耳其语-德语儿童自出生以来一直生活在德国并沉浸在德语环境中，但他们尚未完全掌握德语语音系统。
