儿童的感觉运动加工和成人的高级认知加工可以决定非母语音素的习得方式。本研究考察了习得年龄(AOA)和熟练程度(PL)如何预测统计分离的二语范畴(即范畴内和范畴间)的母语样知觉。在相似性任务中，参与者对英语音节对之间的相似性程度从1(相似)到4(不相似)进行评分。早期的二语习得预测了准确的范畴内归类，而后期的二语习得熟练程度则预示着类别间归类的改善。我们的结果表明，双语者学习对非母语声音进行分类的方式取决于第二语言接触年龄时的认知过程。
Sensorimotor processing in children and higher-cognitive processing in adults could determine how non-native phonemes are acquired. This study investigates how age-of-acquisition (AOA) and proficiency-level (PL) predict native-like perception of statistically dissociated L2 categories, i.e., within-category and between-category. In a similarity task, participants rated the level of similarity between pairs of English syllables from 1 (similar) to 4 (dissimilar). Early L2 acquisition predicts accurate within-categorization and high proficiency in late L2 acquisition predicts improved between-categorization. Our results suggest that the manner in which bilinguals learn to categorize non-native sounds depends on the cognitive processes available at the age of L2 exposure.
