Script knowledge was examined in discourse produced by 15 mildly moderately impaired aphasics, 15 right-hemisphere-damaged (RHD) subjects. 15 neurological patients without central nervous system damage, and 30 normal controls. Experimental task were designed to elicit knowledge of particular scripts, various scripts from a category, metascripts, and plans. The results showed that the brain-damaged patients were able to produce information belonging to a given semantic category of scripts. Disorders demonstrated by both aphasics and RHD patients involved different discourse processes. Aphasics' impairment was mainly connected with discourse macroprocessing. Disturbances in the RHD subjects were found in text structures, contents, and macrostructure. The problem of the probable mechanisms of the observed discourse disturbances were discussed.
对15名轻度至中度失语症患者、15名右脑损伤（RHD）患者、15名无中枢神经系统损伤的神经科患者以及30名正常对照者所产生的语篇进行了脚本知识检查。实验任务旨在引出特定脚本、某一类别中的各种脚本、元脚本和计划的知识。结果表明，脑损伤患者能够生成属于给定语义类别脚本的信息。失语症患者和RHD患者所表现出的障碍涉及不同的语篇过程。失语症患者的损伤主要与语篇宏观处理有关。在RHD患者中，文本结构、内容和宏观结构方面存在干扰。讨论了所观察到的语篇障碍可能的机制问题。
