Abstract

Previous research has shown that when domain-general transitional probability (TP) cues to word segmentation are in conflict with language-specific stress cues, English-learning 5- and 7-month-olds rely on TP, whereas 9-month-olds rely on stress. In two artificial languages, we evaluated English-learning infants’ sensitivity to TP cues to word segmentation vis-a-vis language-specific vowel phonotactic (VP) cues—English words do not end in lax vowels. These cues were either consistent or conflicting. When these cues were in conflict, 10-month-olds relied on the VP cues, whereas 5-month-olds relied on TP. These findings align with statistical bootstrapping accounts, where infants initially use domain-general distributional information for word segmentation, and subsequently discover language-specific patterns based on segmented words.

Research Highlights

Research indicates that when transitional probability (TP) conflicts with stress cues for word segmentation, English-learning 9-month-olds rely on stress, whereas younger infants rely on TP.
In two artificial languages, we evaluated English-learning infants’ sensitivity to TP versus vowel phonotactic (VP) cues for word segmentation.
When these cues conflicted, 10-month-olds relied on VPs, whereas 5-month-olds relied on TP.
These findings align with statistical bootstrapping accounts, where infants first utilize domain-general distributional information for word segmentation, and then identify language-specific patterns from segmented words.

学习英语的婴儿对元音音位线索的敏感性在单词分段中的发展。

以往的研究表明，当领域通用的单词分段过渡概率（TP）线索与语言特有的重音线索发生冲突时，学习英语的 5 个月和 7 个月大的婴儿会依赖 TP，而 9 个月大的婴儿则依赖重音。在两种人工语言中，我们评估了学习英语的婴儿对单词分段的 TP 提示和语言特有的元音音位（VP）提示的敏感性--英语单词不以松散元音结尾。这些线索要么一致，要么相互冲突。当这些线索发生冲突时，10 个月大的幼儿依赖 VP 线索，而 5 个月大的幼儿则依赖 TP 线索。这些发现与统计引导法的观点一致，即婴儿最初使用领域一般的分布信息进行单词分段，随后根据分段的单词发现特定语言的模式。研究亮点：研究表明，当过渡概率（TP）与单词分段的重音线索发生冲突时，学习英语的 9 个月大婴儿依赖重音，而年龄更小的婴儿则依赖过渡概率。在两种人工语言中，我们评估了学习英语的婴儿在分词时对 TP 和元音声策（VP）线索的敏感性。当这些线索发生冲突时，10 个月大的婴儿依赖 VP，而 5 个月大的婴儿则依赖 TP。这些发现与统计引导法的观点一致，即婴儿首先利用领域一般分布信息进行单词分段，然后从分段的单词中识别特定语言的模式。
