本研究探讨了双语者在第二语言（L2）浸泡后，对母语（L1）的感知如何根据与L1接触减少的年龄而有所不同。二十一L1韩国-L2英语双语者在美国，年龄范围从3至15岁，减少接触，和17个控制参与者在韩国进行了测试，感知上的三个L1对比不同的相似性L2对比。与对照组参与者相比，双语者在L1特定对比度上的准确性较低，并且他们的准确性与接触减少的年龄显著相关，这种效果对于与L2最不相似的对比度最为明显。这些发现表明，双语者越早广泛接触L2，他们就越不可能准确地感知L1声音。然而，这种关系是调制跨语言的相似性，和一个转折点，在第二语言习得和L1磨损的语音似乎发生在12岁左右。
This study investigated how bilinguals' perception of their first language (L1) differs according to age of reduced contact with L1 after immersion in a second language (L2). Twenty-one L1 Korean-L2 English bilinguals in the United States, ranging in age of reduced contact from 3 to 15 years, and 17 control participants in Korea were tested perceptually on three L1 contrasts differing in similarity to L2 contrasts. Compared to control participants, bilinguals were less accurate on L1-specific contrasts, and their accuracy was significantly correlated with age of reduced contact, an effect most pronounced for the contrast most dissimilar to L2. These findings suggest that the earlier bilinguals are extensively exposed to L2, the less likely they are to perceive L1 sounds accurately. However, this relationship is modulated by crosslinguistic similarity, and a turning point in L2 acquisition and L1 attrition of phonology appears to occur at around age 12.
