本研究通过测量受试者在听含有暂时性句法歧义的句子时的瞳孔直径来考察其加工努力。在第一个实验中，我们操纵韵律。结果表明，当韵律结构与句法结构发生冲突时，瞳孔直径增大。在第二个实验中，我们操纵韵律和视觉上下文。结果表明，当视觉语境与正确理解一致时，韵律对加工努力的影响很小。然而，当视觉上下文与正确的解释不一致时，韵律对加工努力有很大的影响。视觉语境和韵律之间的相互作用表明，视觉语境对在线加工有影响，它可以调节语言信息源的影响，如韵律。瞳孔测量是一个敏感的测量过程中的处理努力的口语理解。
This study investigated processing effort by measuring peoples' pupil diameter as they listened to sentences containing a temporary syntactic ambiguity. In the first experiment, we manipulated prosody. The results showed that when prosodic structure conflicted with syntactic structure, pupil diameter reliably increased. In the second experiment, we manipulated both prosody and visual context. The results showed that when visual context was consistent with the correct interpretation, prosody had very little effect on processing effort. However, when visual context was inconsistent with the correct interpretation, prosody had a large effect on processing effort. The interaction between visual context and prosody shows that visual context has an effect on online processing and that it can modulate the influence of linguistic sources of information, such as prosody. Pupillometry is a sensitive measure of processing effort during spoken language comprehension.
