失语症患者的动词和句子经常受损，不同类型的失语症与不同的受损模式有关。然而，目前可用的测试电池，它是具有挑战性的，以提供一个全面的配置文件的失语症语言障碍，因为他们不检查动词和句子的句法重要属性。本研究提供的数据来自西北评估的动词和句子（NAVS），一个新的测试电池，旨在检查失语症的句法缺陷。NAVS包括对动词命名和理解的测试，以及在简单主动句中产生动词论元结构的测试，每个测试都考察了论元数量和可选性的影响。NAVS还测试规范和非规范句子的产生和理解。共有59名失语症患者（35名语法错误和24名命名错误）使用一组动作图片进行了测试。参与者制作动词或句子的生产子测试和识别图片对应的courserily提供的动词或句子的理解子测试。语法组，与失范组相比，表现出显着更差的所有子测试，除了动词的理解，和两组的理解比生产受损。在动词命名和论元结构产生测试中，两组学生都表现出了三论元动词的困难，这受到论元数量和可选性的影响。然而，生产的句子使用三个参数的动词更受损的语法，相比，失范，组。在句子生成和理解测试中，语法组在所有类型的非规范句子中表现出障碍，而失范组主要表现出最困难的对象相对结构的困难。结果表明，动词和句子赤字与语法性失语症的个人在很大程度上受到句法复杂性的影响，然而，个人与命名性失语症似乎表现出这些障碍，只有最复杂的形式的动词和句子。目前的数据表明，NAVS是有用的特点与失语症的人动词和句子赤字。
Verbs and sentences are often impaired in individuals with aphasia, and differential impairment patterns are associated with different types of aphasia. With currently available test batteries, however, it is challenging to provide a comprehensive profile of aphasic language impairments because they do not examine syntactically important properties of verbs and sentences. This study presents data derived from the Northwestern Assessment of Verbs and Sentences (NAVS), a new test battery designed to examine syntactic deficits in aphasia. The NAVS includes tests for verb naming and comprehension, and production of verb argument structure in simple active sentences, with each examining the effects of the number and optionality of arguments. The NAVS also tests production and comprehension of canonical and non-canonical sentences. A total of 59 aphasic participants (35 agrammatic and 24 anomic) were tested using a set of action pictures. Participants produced verbs or sentences for the production subtests and identified pictures corresponding to auditorily provided verbs or sentences for the comprehension subtests. The agrammatic group, compared to the anomic group, performed significantly more poorly on all subtests except verb comprehension, and for both groups comprehension was less impaired than production. On verb naming and argument structure production tests both groups exhibited difficulty with three-argument verbs, affected by the number and optionality of arguments. However, production of sentences using three-argument verbs was more impaired in the agrammatic, compared to the anomic, group. On sentence production and comprehension tests, the agrammatic group showed impairments in all types of non-canonical sentences, whereas the anomic group exhibited difficulty primarily with the most difficult, object relative, structures. Results show that verb and sentence deficits seen in individuals with agrammatic aphasia are largely influenced by syntactic complexity; however, individuals with anomic aphasia appear to exhibit these impairments only for the most complex forms of verbs and sentences. The present data indicate that the NAVS is useful for characterising verb and sentence deficits in people with aphasia.
