Sixty aphasic patients and 55 normal control subjects were tested on a sentence production protocol that required subjects to produce specific sentence types from semantic representations. Normal subjects produced the expected targets with great reliability. Analysis of the patients' performance indicated that patients had difficulty producing both grammatical forms and thematic roles. Patients had more trouble producing grammatical elements than content words, and showed differential difficulty on sentence types that had more grammatical elements and in which the order of thematic roles was non-canonical. The results provide evidence regarding the processing load imposed by different components of the sentence production process.
60名失语症患者和55名正常对照受试者接受了一项句子生成协议测试，该协议要求受试者根据语义表征生成特定的句子类型。正常受试者能够高度可靠地生成预期目标。对患者表现的分析表明，患者在生成语法形式和题元角色方面都有困难。患者在生成语法成分方面比生成实词更困难，并且在具有更多语法成分且题元角色顺序不规范的句子类型上表现出不同程度的困难。这些结果为句子生成过程中不同成分所施加的处理负荷提供了证据。
