我们的问题是，通过另一种语言——西班牙语，增加对抑扬格、重音在第二个音节上的双音节单词（如吉他）的接触，是否有助于英语婴儿学习抑扬格的分割。西班牙语的抑扬格词汇（40%）是英语的两倍（20%）。我们使用头转向偏好程序测试了双语西班牙语和英语学习8个月大的婴儿分割英语抑扬格的能力。单语英语学习婴儿只有在11个月大的时候才能完成这项任务。我们发现，在8个月大的时候，西班牙语和英语双语学习的婴儿成功地分割了英语的抑扬格，而不仅仅是重读音节，这与他们的单语英语学习的同龄人不同。在同样的年龄，双语婴儿不能区分西班牙语抑扬格，就像他们的单语西班牙同龄人一样。这些结果不能解释为双语婴儿在两种母语中对过渡概率线索的依赖，因为两种语言的统计线索具有可比性。相反，基于他们的加速发展，我们认为双语婴儿的两种语言的自主但相互依存的发展。
We asked whether increased exposure to iambs, two-syllable words with stress on the second syllable (e.g.,guitar), by way of another language – Spanish – facilitates English learning infants' segmentation of iambs. Spanish has twice as many iambic words (40%) compared to English (20%). Using the Headturn Preference Procedure we tested bilingual Spanish and English learning 8-month-olds' ability to segment English iambs. Monolingual English learning infants succeed at this task only by 11 months. We showed that at 8 months, bilingual Spanish and English learning infants successfully segmented English iambs, and not simply the stressed syllable, unlike their monolingual English learning peers. At the same age, bilingual infants failed to segment Spanish iambs, just like their monolingual Spanish peers. These results cannot be explained by bilingual infants' reliance on transitional probability cues to segment words in both their native languages because statistical cues were comparable in the two languages. Instead, based on their accelerated development, we argue for autonomous but interdependent development of the two languages of bilingual infants.
