We present three experiments designed to investigate the role of prosody during sentence processing. The first investigated the question of whether an utterance's prosodic contour influences its comprehension on-line. We spliced the beginning and end portions of direct object and embedded clause sentences and observed the consequent effects on comprehension using a dual-task procedure to measure processing load. Our second experiment sought to determine whether the constituent structure of these sentences could be reliably predicted using prosodic information. We found that the duration and F0 contour associated with the main-clause verb and the following NP reliably distinguished between the direct object and embedded clause constructions. In the final experiment, we manipulated the duration of the main-clause verb and found that subjects used this information to guide their initial parse during on-line sentence comprehension. The need for a model of sentence processing that addresses the use of prosodic information is discussed.
我们展示了三个旨在研究韵律在句子处理过程中作用的实验。第一个实验研究了话语的韵律轮廓是否会在线影响其理解这一问题。我们拼接了直接宾语和嵌入子句句子的开头和结尾部分，并使用双任务程序来测量处理负荷，观察由此对理解产生的影响。我们的第二个实验试图确定是否可以使用韵律信息可靠地预测这些句子的成分结构。我们发现，与主句动词和后续名词短语相关的时长和基频轮廓能够可靠地区分直接宾语和嵌入子句结构。在最后一个实验中，我们操纵了主句动词的时长，发现受试者在在线句子理解过程中会利用这些信息来指导他们的初始句法分析。文中讨论了建立一个处理韵律信息使用问题的句子处理模型的必要性。
