听语音需要适应信号中的大量变异性。本研究考察了第二语言适应灵活性与第二语言语音表征稳健性之间的关系。德国英语学习者的语音编码和语音灵活性分别通过包含语音替代的非单词的词汇判断任务和分配学习任务来评估。性能分析分为容易的(/i/-/i/)和困难的对比(/epsilon/-/ae/，其中/ae/在德语中不存在)。结果表明，FOR/I/-/I/听者在词汇判断上是相当准确的，而分布式学习持续地引发了范畴化的变化。对于/epsilon/-/ae/，词汇决定成绩较差，但个体被试的成绩与分配学习成绩有关：学习者的词汇决定成绩越好，他们的分类迁移就越小。这表明，对于困难的二语对比，语音层面的僵化与更好的词汇表现有关。
Listening to speech entails adapting to vast amounts of variability in the signal. The present study examined the relationship between flexibility for adaptation in a second language (L2) and robustness of L2 phonolexical representations. Phonolexical encoding and phonetic flexibility for German learners of English were assessed by means of a lexical decision task containing nonwords with sound substitutions and a distributional learning task, respectively. Performance was analyzed for an easy (/i/-/I/) and a difficult contrast (/epsilon/-/ae/, where /ae/ does not exist in German). Results showed that for /i/-/I/ listeners were quite accurate in lexical decision, and distributional learning consistently triggered shifts in categorization. For /epsilon/-/ae/, lexical decision performance was poor but individual participants' scores related to performance in distributional learning: the better learners were in their lexical decision, the smaller their categorization shift. This suggests that, for difficult L2 contrasts, rigidity at the phonetic level relates to better lexical performance.
