这项研究探索了10到11个月大的婴儿对母语的语音特征的敏感性。事件相关电位(ERPs)被记录在故事的两个版本上：未修改的版本包含正常的英语功能语素，而修改版本的功能语素子集的韵律和节段性被改变以使其成为非典型的。11个月大的婴儿在修改后的故事中对声调的ERPs显著低于未修改的故事，而10个月大的婴儿则没有差异。这些结果表明，11个月大的婴儿根据他们对英语语音特征的表征来区分故事的两个版本。此外，声调探测事件相关电位方法可以成功地用于研究语言前期婴儿的言语知觉发展。
The study explores 10- to 11-month-old infants' sensitivity to the phonological characteristics of their native language. Event-related potentials (ERPs) were obtained for tones that were superimposed on two versions of a story: an Unmodified version containing normal English function morphemes, and a Modified version in which the prosodic and segmental properties of a subset of function morphemes were changed to make them atypical. The 11-month-olds exhibited significantly lower amplitude ERPs to the tones during the Modified story than to the Unmodified story, whereas the 10-month-olds showed no differences. These results suggest that the 11-month-olds discriminated the two versions of the story based on their representations of the phonological properties of English. Further, the tone-probe ERP method can successfully be used to study the development of speech perception in the pre-linguistic infant.
