背景：词汇偏向假说认为，当动词的论元结构偏向与句子结构相冲突时，失语症患者理解句子有困难。这一假设可以解释影响简单句子的理解缺陷，但动词偏见在暂时性歧义句子中的作用还没有得到明确的证明。目的：本研究考察了动词偏见如何影响对暂时歧义和无歧义句子的理解。方法与程序：PWA和控制组阅读含有句子补语的句子(例如，天才摄影师承认火灾是无法阻止的)。主要动词偏向直接宾语(如接受)或句子补语(如承认)。结果：PWA的阅读时间受动词偏向的影响大于受补语存在与否的影响，而控制组的阅读时间受有无补语的影响较大。结论：实验结果与词汇偏误假说基本一致，表明动词偏向与句子结构的不匹配影响了PWA中无歧义和暂时性歧义句子的加工。
Background: The Lexical Bias Hypothesis claims that people with aphasia (PWA) have difficulty understanding sentences when the verb's argument structure bias conflicts with the sentence structure. This hypothesis can account for comprehension deficits that affect simple sentences, but the role of verb bias has not been clearly demonstrated in temporarily ambiguous sentences.Aims: This study examined how verb bias affects comprehension of temporarily ambiguous and unambiguous sentences using self-paced reading.Methods & Procedures: PWA and controls read sentences that contained sentential complements (e.g., The talented photographer accepted (that) the fire could not have been prevented). The main verb was biased to take a direct object (e.g., accepted) or a sentential complement (e.g., admitted). In addition, the sentential complement was either introduced by the complementiser that (i.e., unambiguous) or unmarked (i.e., ambiguous).Results: The reading times of PWA were affected more by verb bias than by the presence of the complementiser, whereas the control group's reading times were more affected by the presence or absence of the complementiser.Conclusions: The results were generally consistent with the Lexical Bias Hypothesis, and showed that a mismatch between verb bias and sentence structure affected the processing of unambiguous and temporarily ambiguous sentences in PWA.
