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.
报告了一项正在进行的关于创伤性脑损伤（TBI）成人患者叙事话语表现与执行功能之间潜在关系的初步研究结果。从32名患有创伤性脑损伤的成人中收集了叙事故事。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。然后将这些指标与执行功能的主要测量指标威斯康星卡片分类测验（WCST）的得分进行关联。结果发现，WCST的一个因子得分与故事结构指标之间存在显著相关性，但与句子生成或衔接充分性指标无关。这些结果表明，在寻找叙事话语功能障碍的潜在因果因素时，执行功能可能是一个有前景的研究方向，从而能更好地描述创伤性脑损伤继发的交流缺陷的本质。
