学习将语音流解析成句法成分是成人句子理解的重要前提，韵律是可用于此任务的信息来源之一。为了测试韵律在促进成分学习中的作用，19个月大的婴儿熟悉与1-子句（ABCDEF）或2-子句（ABC，DEF）韵律的非单词句子，然后测试代表语法（DEF，ABC）或不语法（EFA，BCD）的句子从2-子句熟悉的句子“运动”的子句。如果两小句组的婴儿能够使用韵律将单词组合成有凝聚力的组块，他们应该区分测试项目中的语法和非语法运动，即使测试句子有一个新的韵律轮廓。第一条款、对照组不应歧视。结果支持这些预测，并表明，婴儿对待韵律分组的话更有凝聚力和成分比跨越韵律边界的话。后续的实验表明，这些结果并不只是反映了识别的边界位置或声学相似的词在熟悉和测试阶段的话。
Learning to parse the speech stream into syntactic constituents is a crucial prerequisite to adult-like sentence comprehension, and prosody is one source of information that could be used for this task. To test the role of prosody in facilitating constituent learning, 19-month-olds were familiarized with non-word sentences with 1-clause (ABCDEF) or 2-clause (ABC, DEF) prosody and were then tested on sentences that represent a grammatical (DEF, ABC) or ungrammatical (EFA, BCD) 'movement' of the clauses from the 2-clause familiarization sentences. If infants in the 2-clause group are able to use prosody to group words into cohesive chunks, they should discriminate between grammatical and ungrammatical movements in the test items, even though the test sentences have a new prosodic contour. The 1-clause, control, group should not discriminate. Results support these predictions and suggest that infants treat prosodically-grouped words as more cohesive and constituent-like than words that straddle a prosodic boundary. A follow-up experiment suggests that these results do not merely reflect recognition of words in boundary positions or acoustic similarity of words across the familiarization and test phases.
