We report three experiments with language-impaired and unimpaired speakers of Italian, assessing: (1) whether nonsyntactic (both conceptual and morphophonological) information is used in encoding the syntactic structure of a sentence; and (2) whether the integration of syntactic and non-syntactic information can be differentially impaired in Broca's aphasics. In all the experiments, gender agreement errors between a noun, subject of the sentence, and a predicative adjective were induced by presenting participants with sentence fragments to complete. The first experiment assessed the role of conceptual information. The second experiment investigated whether agreement is disrupted by the presence of another noun with different gender in the subject noun phrase. In the last experiment, we assessed whether morphophonological cues are used. We found that both populations used nonsyntactic information (both conceptual and morphophonological). However, patients were disrupted to a greater extent than normals by the presence of a gender mismatching noun in the subject noun phrase. The results are discussed in terms of how information integration during production is achieved and how it can be disrupted in aphasia.
我们报告了针对意大利语有语言障碍和无语言障碍的说话者的三项实验，评估：（1）非句法信息（包括概念性和形态语音学信息）是否用于句子句法结构的编码；以及（2）句法信息和非句法信息的整合在布罗卡失语症患者中是否会受到不同程度的损害。在所有实验中，通过向参与者呈现待完成的句子片段，引发句子主语名词与谓语形容词之间的性别一致错误。第一个实验评估概念性信息的作用。第二个实验研究主语名词短语中出现另一个不同性别的名词是否会干扰一致性。在最后一个实验中，我们评估是否使用了形态语音线索。我们发现，两组人群都使用非句法信息（包括概念性和形态语音学信息）。然而，主语名词短语中出现性别不匹配的名词时，患者比正常人受到的干扰更大。我们从句子生成过程中信息整合是如何实现的以及在失语症中如何被破坏的角度对结果进行了讨论。
