The proposed studies will examine how prosodic marking of the given/new distinction interacts with lexical stress to facilitate or impede infants use of speech rhythm in identifying words. Languages vary in how these different influences on prosody interact; therefore, to begin to get a handle on the cross-linguistic generality of early language processing it is important to examine whether certain prosodic cues (e.g., given vs. new stress) are consistent across languages, and whether these cues interact with prosody that is language specific (e.g., word-initial vs. non-word-initial lexical stress). Four studies are proposed: 1) an acoustic analysis of the given/new stress present in English and Spanish infant-directed speech, 2) an extension of work (Morgan, 1996b) examining predominantly English-exposed infants segmentation biases, however examining these biases in predominantly Spanish-exposed infants, and 3/4) perceptual studies of the influence of naturally produced given/new and lexical stress on English- and Spanish-exposed infants speech segmentation abilities. The specific methodologies relevant to these perceptual studies are a word monitoring procedure and a noise-detection method introduced by Morgan (1996a) that are based on the conditioned head turning method traditionally used to study infant speech perception.

拟议的研究将探讨韵律标记的给定/新的 区别与词汇重音相互作用， 婴儿在识别单词时使用语音节奏。语言各不相同 这些对韵律的不同影响是如何相互作用的;因此，开始 掌握早期语言的跨语言共性 重要的是检查某些韵律线索是否 (e.g., given vs. new stress）在不同语言中是一致的， 这些线索是否与语言特有的韵律相互作用 (e.g.,词首与非词首词汇重音）。 四项研究 提出了：1）声学分析的给定/新的应力存在 在英语和西班牙语婴儿导向的讲话，2）工作的延伸 （Morgan，1996 b）检查主要接触英语的婴儿 细分偏见，然而，检查这些偏见，主要是 接触西班牙语的婴儿，以及3/4）对影响的知觉研究 英语中自然产生的given/new和词汇重音-以及 西班牙语暴露的婴儿语音分割能力。 具体 与这些知觉研究相关的方法论是一个词监控 程序和噪声检测方法介绍了摩根（1996年a）， 基于传统上用于 研究婴儿言语知觉。
