目的本研究检验了关于神经健康成人和患有布罗卡失语症的成年人处理 wh 问题的 3 个假设。方法我们对 32 名未受损的参与者（实验 1）和 8 名患有布罗卡失语症的参与者（实验 2）使用了听时眼动追踪方法。收集了准确性、响应时间和在线注视数据。结果在实验 1 中，我们建立了一个基线，用于说明 4 种类型的 wh 问题（主语和客体提取的 who 和which 问题）的无损处理和理解如何表现。实验 1 中的 3 个假设中的任何一个都没有找到明确的支持。然而，在布罗卡参与者的实验 2 中，我们发现相对于其他条件，在对象提取哪个问题中，准确率明显较低，响应时间较慢，并且对我们的注视数据的干扰增加。结论我们的结果为介入者假设提供了支持，该假设指出，在移位的名词短语与其间隙位置结果之间包含介入者（词汇名词短语）的句子结构相对于其他结构，其在加工上存在显着的劣势。我们认为，这一假设为一些布罗卡失语症参与者的理解缺陷提供了令人信服的解释。
PurposeThis study examines 3 hypotheses about the processing ofwh-questions in both neurologically healthy adults and adults with Broca's aphasia.MethodWe used an eye tracking while listening method with 32 unimpaired participants (Experiment 1) and 8 participants with Broca's aphasia (Experiment 2). Accuracy, response time, and online gaze data were collected.ResultsIn Experiment 1, we established a baseline for how unimpaired processing and comprehension of 4 types ofwh-question (subject- and object-extractedwho-andwhich-questions) manifest. There was no unambiguous support found for any of the 3 hypotheses in Experiment 1. In Experiment 2 with the Broca's participants, however, we found significantly lower accuracy, slower response times, and increased interference in our gaze data in the object-extractedwhich-questions relative to the other conditions.ConclusionsOur results provide support for the intervener hypothesis, which states that sentence constructions that contain an intervener (a lexical noun phrase) between a displaced noun phrase and its gap site result in a significant processing disadvantage relative to other constructions. We argue that this hypothesis offers a compelling explanation for the comprehension deficits seen in some participants with Broca's aphasia.
