词形分词能力在出生后的第一年就出现了，有人提出，婴儿最初依靠两种类型的线索从流利的言语中提取单词：过渡概率（TPs）和节奏单位。本研究的主要目的是利用头部转向偏好程序（HPP）的行为方法，再次研究法语学习婴儿在切分能力开始时（大约8个月）在如此小的年龄反复未能找到音节切分的情况下对音节单位的节奏切分。第二个目的是探讨法语学习婴儿在分词过程中音节单位的使用与音节单位的相互作用。其基本原理是，减少双音节词中嵌入的目标音节周围的TP线索，可以阻止双音节分词，有利于观察音节分词。在实验1和2中，婴儿在TP中度减少的条件下进行测试；没有发现音节或双音节分词的证据。在实验3中，婴儿在TP减少更明显的条件下进行测试，观察到新颖性音节分割效应。因此，本研究首先建立了法语学习婴儿的早期音节分割，从基于音节的语言为节奏单位在分割能力开始时使用的建议提供了支持。其次，它证实了学法语的婴儿对TP线索很敏感。第三，这表明他们对韵律线索和韵律线索的相对权重很敏感，这解释了为什么在高韵律线索的语境中没有观察到音节分割的影响。这些发现与分词自举理论有关，以及关于早期语言习得的统计与韵律基础的更大争论。
Word form segmentation abilities emerge during the first year of life, and it has been proposed that infants initially rely on two types of cues to extract words from fluent speech: Transitional Probabilities (TPs) and rhythmic units. The main goal of the present study was to use the behavioral method of the Headturn Preference Procedure (HPP) to investigate again rhythmic segmentation of syllabic units by French-learning infants at the onset of segmentation abilities (around 8 months) given repeated failure to find syllabic segmentation at such a young age. The second goal was to explore the interaction between the use of TPs and syllabic units for segmentation by French-learning infants. The rationale was that decreasing TP cues around target syllables embedded in bisyllabic words would block bisyllabic word segmentation and facilitate the observation of syllabic segmentation. In Experiments 1 and 2, infants were tested in a condition of moderate TP decrease; no evidence of either syllabic or bisyllabic word segmentation was found. In Experiment 3, infants were tested in a condition of more marked TP decrease, and a novelty syllabic segmentation effect was observed. Therefore, the present study first establishes early syllabic segmentation in French-learning infants, bringing support from a syllable-based language to the proposal that rhythmic units are used at the onset of segmentation abilities. Second, it confirms that French-learning infants are sensitive to TP cues. Third, it demonstrates that they are sensitive to the relative weight of TP and rhythmic cues, explaining why effects of syllabic segmentation are not observed in context of high TPs. These findings are discussed in relation to theories of word segmentation bootstrapping, and the larger debate about statistically- versus prosodically-based accounts of early language acquisition.
