本文报道了一项正在进行的关于成人创伤性脑损伤患者的叙事性话语表现与执行功能之间潜在关系的研究的初步结果。32名成人脑外伤患者的叙事性故事被引出。故事从三个层面进行分析：句子生成、句间衔接充分性和故事情节结构。然后，这些测量与威斯康星州卡片分类测试(WCST)的分数相关联，WCST是执行功能的主要测量标准。WCST的一个因素得分与故事结构的测量之间有显著的相关性，但与句子产出或衔接充分性无关。这些结果表明，在寻找叙述性语篇功能障碍的潜在原因方面，执行功能可能是一个很有前途的途径，从而更好地描绘出继发于任务型话语的交际缺陷的性质。
Preliminary findings from an ongoing investigation of the potential relationship between narrative discourse performance and executive functions in adults with traumatic brain injuries (TBI) are reported. Narrative stories were elicited from 32 adults with TBI. Stories were analysed at three levels: sentence production, intersentential cohesive adequacy, and story episode structure. These measures were then correlated with scores from the Wisconsin Card Sorting Test (WCST), the primary measure of executive function. A significant correlation was noted between a factor score from the WCST and the measure of story structure, but not sentence production or cohesive adequacy. These results suggest that executive functions may be a promising avenue to pursue in the search for underlying causal factors of narrative discourse dysfunction and, therefore to better delineate the nature of communicative deficits secondary to TBI.
