本研究比较了Broca失语症和Wernicke失语症患者的句子生成能力，试图探讨词汇检索障碍在多大程度上阻碍了句子生成。当提供不同数量的词汇信息时，测试了产生主动和被动可逆和非可逆句子的能力。结果表明，Wernicke失语症和Broca失语症患者在被动句生成方面均存在障碍，并且在提供词汇提示（相关名词和未屈变动词）的情况下，这些障碍并未得到克服。然而，当助动词和过去时语素与动词干一起提供时，两组被动句的生成都有显著提高。然而，对错误模式的分析揭示了两组人之间的差异，这表明布洛卡的失语症受试者可能会因为检索相关语法语素的问题而发现被动句很难。患有韦尼克失语症的受试者可能无法自动使用被动句结构。(C) 2002 Elsevier Science （USA）。版权所有。
This study compared the sentence production abilities of individuals with Broca's and Wernicke's aphasia in an attempt to explore the extent to which impaired lexical retrieval impedes sentence production. The ability to produce active and passive reversible and non-reversible sentences was examined when varying amounts of lexical information was provided. The results showed that both Wernicke's and Broca's aphasic individuals were impaired in passive sentence production and that these difficulties were not overcome when lexical cues (the relevant nouns and uninflected verb) were provided. However when auxiliary and past tense morphemes were provided along with the verb stem, production of passive sentences improved drastically for both groups. Analysis of error patterns, however, revealed differences between the two groups, suggesting that Broca's aphasic subjects may find passive sentences difficult due to problems with retrieving the relevant grammatical morphemes. Subjects with Wernicke's aphasia may have been unable to automatically access the passive sentence structure. (C) 2002 Elsevier Science (USA). All rights reserved.
