to investigate prosodic boundary effects on the comprehension of attachment ambiguities in Brazilian Portuguese and to test two hypotheses relying on the notion of boundary strength: the absolute boundary hypothesis (ABH) and the relative boundary hypothesis (RBH). Manipulations of prosodic structure influence how listeners interpret syntactically ambiguous sentences. However, the role of prosody in spoken language comprehension of sentences has received limited attention in languages other than English, particularly from a developmental perspective.
Twenty-three adults and 15 children participated in a computerized sentence comprehension task involving syntactically ambiguous sentences. Each sentence was recorded in eight different prosodic forms with acoustic manipulations of F0, duration and pause varying the boundary size to reflect predictions of the ABH and RBH.
Children and adults differed in how prosody influenced their syntactic processing and children were significantly slower than adults. Results indicated that interpretation of sentences varied according to their prosodic forms.
Neither the ABH or the RBH explained how children and adults who speak Brazilian Portuguese use prosodic boundaries to disambiguate sentences. There is evidence that the way prosodic boundaries influence disambiguation varies cross-linguistically.
研究韵律边界对巴西葡萄牙语中附着歧义理解的影响，并检验两个依赖于边界强度概念的假设：绝对边界假设（ABH）和相对边界假设（RBH）。韵律结构的操纵会影响听者对句法上歧义句子的解释。然而，在英语以外的语言中，韵律在口语理解中的作用，尤其是从发展的角度来看，受到的关注有限。
23 名成年人和 15 名儿童参与了一项涉及句法歧义句子的计算机化句子理解任务。每个句子都以八种不同的韵律形式记录下来，通过对 F0、时长和停顿的声学操纵来改变边界大小，以反映 ABH 和 RBH 的预测。
儿童和成人在韵律如何影响他们的句法处理方面存在差异，儿童明显比成人慢。结果表明，句子的解释根据它们的韵律形式而变化。
巴西葡萄牙语的儿童和成人既不遵循 ABH，也不遵循 RBH 来利用韵律边界来消除句子歧义。有证据表明，韵律边界对消歧的影响在跨语言中是不同的。
