对28名失语症患者进行了6项任务的测试，其中6项任务是用来评估“非命题”语音的，6项任务是用来评估命题语音的。在数字和图片命名任务中，在一组失语症患者中，非命题和命题言语类型行为之间的区别是最可靠的。在一周中的几天和短语重复任务中观察到的影响较小。在28名患者中，只有6名在任务比较范围内始终显示出非命题优势。然而，主成分分析提取了两个因素，它们很好地区分了命题和非命题任务。我们得出的结论是，非命题言语，在某种程度上是通过这些任务来衡量的，在失语症患者中作为一个群体并不被保留，尽管一些患者可能表现出相当一致的非命题优势。然而，命题和非命题言语之间的区别似乎确实适用于失语症。错误分析支持命题任务涉及语义加工的猜想，而非命题任务可能会给语音加工带来更大的负担。(C)1994年学术出版社。
Twenty-eight aphasic patients were tested on six tasks designed to assess ''nonpropositional'' speech and six matched tasks designed to assess propositional speech. The most reliable differentiation between nonpropositional and propositional speech type behaviors within a group of aphasics was found for the Numbers and Picture naming tasks. A smaller effect was observed on the Days of the week and Phrase repetition tasks. Only 6 of the 28 patients consistently showed a nonpropositional advantage across the range of task comparisons. However, a principal components analysis extracted two factors which differentiated propositional from nonpropositional tasks reasonably well. We conclude that nonpropositional speech, to the extent that it is measured by these tasks, is not preserved in aphasics as a group, though some patients may show a fairly consistent nonpropositional advantage. The distinction between propositional and nonpropositional speech does appear to have some application to aphasia, however. An error analysis supports the conjecture that propositional tasks involve semantic processing while nonpropositional tasks may place a greater load on phonological processing.
