本研究探讨了在句子理解中定义“规范形式”的三个因素：句法结构、语义角色和使用频率。我们首先研究的索赔，句子包含unperpetitive动词提出的困难类似于被动句。使用可解释性判断任务，我们表明，一个混合组的失语症表现出显着更好的unconciliatives比被动。然后，我们转向观察，被动通常比失语症患者的主动更难。我们发现，这种效果是调制词汇偏见，即，一个动词出现在特定句法结构中的可能性：被动偏向动词的被动句明显比主动偏向动词的被动句容易。更一般地说，结构与主要动词的词汇偏向相匹配的句子比结构和词汇偏向不匹配的句子要容易得多。这些发现表明，“规范形式”反映了频率和词汇偏见。(C)2003年爱思唯尔公司All rights reserved.
This study investigates three factors that have been argued to define "canonical form" in sentence comprehension: Syntactic structure, semantic role, and frequency of usage. We first examine the claim that sentences containing unaccusative verbs present difficulties analogous to those of passive sentences. Using a plausibility judgment task, we show that a mixed group of aphasics performed significantly better on unaccusatives than on passives. We then turn to the observation that passives are generally harder than actives for aphasics. We show that this effect is modulated by lexical bias, i.e., the likelihood that a verb appears in a given syntactic structure: Passives of passive-bias verbs were significantly easier than passives of active-bias verbs. More generally, sentences whose structure matches the lexical bias of the main verb are significantly easier than sentences in which structure and lexical bias do not match. These findings suggest that "canonical form" reflects frequency and lexical biases. (C) 2003 Elsevier Inc. All rights reserved.
