Abstract

The study described the abilities of a group of 15 moderately impaired aphasics and 15 normals to produce narrative discourse. The experimental tasks included telling stories, summarizing stories, and giving morals to stories. The data were analyzed in terms of sentential grammar, discourse grammar, and subjective ratings of content and clarity of language. The results showed that aphasics produced well-structured discourse. The language of the aphasics' discourse was reduced in both complexity and amount, as compared to that produced by normals. The reduction of language reflected selective reduction of hierarchically organized information. The findings of the study confirm the results of previous research on mildly impaired aphasics, which also showed preservation of discourse structure with selective reduction of information.

摘要

该研究描述了一组15名中度失语症患者和15名正常人进行叙事话语的能力。实验任务包括讲故事、总结故事以及讲述故事的寓意。数据依据句子语法、话语语法以及对内容和语言清晰度的主观评分进行分析。结果显示，失语症患者能够产出结构良好的话语。与正常人产出的话语相比，失语症患者话语的语言在复杂性和数量上均有所减少。语言的减少反映了分层组织信息的选择性减少。该研究结果证实了先前对轻度失语症患者的研究结果，该研究也表明话语结构得以保留，但信息有选择性地减少。
