从康复机构招募的两组成年人中，55名闭合性脑损伤（CHI）患者和47名非脑损伤（NBI）患者，在复述和生成两个故事任务中获得叙述。在东北部的三个州。参与者根据他们的社会经济地位（SES）被分类为专业工人、技术工人或非技术工人。在句子生成、句子间衔接和故事语法的层面上使用五种话语测量来分析叙事。然后在小组、任务和SES水平之间比较话语表现。智障组的话语表现也与他们在威斯康辛卡片分类测试（一种衡量执行功能的测试）中的得分进行了比较。结果表明，两种话语测量可以区分群体。与NBI组相比，CHI组每个t单位和情节结构中的t单位产生的单词明显更少，这归因于内容组织方面的困难。CHI组和NBI组的故事复述任务和故事生成任务在所有五个话语测量上的表现都不同。所有参与者在故事基因分配任务中都比在故事复述任务中产生了更长、语法更复杂的t单位。然而，故事复述任务的衔接充分性和故事语法比故事生成任务好。因此得出的结论是，对两组人来说，故事生成比故事复述更具挑战性。SES的唯一显著差异涉及到间隙衔接的测量。非技术工人表现出较差的凝聚力。无论是熟练工人还是专业人员，无论小组任务还是故事任务。最后，在两个故事任务中，CHI组的话语表现与威斯康星卡片分类得分之间存在适度的相关性。
Narratives were elicited in two story tasks, retelling and generation, from two groups of adults, 55 with closed head injury (CHI) and 47 non-brain-injured (NBI), recruited from rehabilitation facilities. in three northeastern states. Participants were classified, on the basis of their socioeconomic status (SES), as professional, skilled worker, or unskilled worker. Narratives were analyzed using five discourse measures at the levels of sentence production, intersentential cohesion, and story grammar. Discourse performance was then compared across groups, tasks, and SES levels. Discourse performance of the CHI group was also compared with their scores from the Wisconsin Card Sorting Test, a measure of executive functioning. results indicated that two discourse measures, distinguished the groups. The CHI participants produced significantly fewer words per T-unit and fewer T-units within episode structure than did the NBI group, which was attributed to difficulties with content organization. Performance on all five discourse measures differed for the, story retelling versus the story generation tasks for both CHI and NBI groups. All participants produced longer and more grammatically complex T-units in the story gene ration task than in story retelling. However, cohesive adequacy and story grammar were better in the story retelling task than in the story generation task. It was therefore concluded that story generation was a more challenging task than story retelling for both groups. The only significant difference noted for SES involved the measure of intersentential cohesion. The unskilled workers demonstrated poorer cohesive adequacy. than either the skilled workers or professionals, regardless of group or story task. Finally, modest correlations were noted between the discourse performance of the CHI group and scores from the Wisconsin Card Sorting lest in both story tasks.
