This article examines whether children alter a variable phonological pattern in an artificial language towards a phonetically-natural form. We address acquisition of a variable rounding harmony pattern through the use of two artificial languages; one with dominant harmony pattern, and another with dominant non-harmony pattern. Overall, children favor harmony pattern in their production of the languages. In the language where harmony is non-dominant, children's subsequent production entirely reverses the pattern so that harmony predominates. This differs starkly from adults. Our results compare to the regularization found in child learning of morphosyntactic variation, suggesting a role for naturalness in variable phonological learning.

变化等待偏差：元音和声变化的实质性偏差学习

本文研究儿童是否将人工语言中的可变语音模式改变为语音自然形式。我们通过使用两种人工语言来解决可变舍入和谐模式的获取；一种以和声为主，另一种以非和声为主。总的来说，孩子们在他们的语言生产中偏爱和声模式。在和谐不占主导地位的语言中，儿童的后续生产完全颠倒了格局，以和谐为主。这与成年人截然不同。我们的结果与儿童学习形态句法变化中发现的正则化进行了比较，表明自然性在可变语音学习中的作用。
