Adults with right hemisphere damage demonstrate differences in connected speech compared to controls, but systematic, quantitative methods to capture these differences are lacking. The current study aimed to (a) investigate if measures using the Modern Cookie Theft picture description would identify discourse differences in acute right hemisphere stroke, and (b) examine if discourse differences were associated with documented cognitive impairment.
Eighty-four participants completed the Modern Cookie Theft picture description within 5 days of right hemisphere stroke. Descriptions were analyzed for multiple microlinguistic characteristics. Medical charts were retrospectively reviewed for documented presence of cognitive impairment.
Individuals with acute right hemisphere stroke produced fewer content units, total syllables, and lower left-right content unit ratios compared to controls, indicating a paucity of informativeness. Presence of cognitive impairment was associated with fewer content units produced.
Multiple measures of microlinguistic discourse characteristics differentiated adults with right hemisphere stroke from controls, highlighting variations in both the quantity and quality of connected speech. Findings continue to underscore the contribution and correlation between cognitive skills and discourse performance. Future work is needed to assess the relationship between particular cognitive domains and discourse production as well as to investigate longitudinal changes to discourse production during stroke recovery.
与对照组相比，右脑损伤的成年人在连贯话语中表现出差异，但缺乏系统的、定量的方法来捕捉这些差异。本研究旨在：（a）探讨使用现代 Cookie 盗窃图片描述的方法是否能识别急性右脑卒中患者的话语差异；（b）研究话语差异是否与已记录的认知障碍有关。
84 名参与者在右脑卒中后 5 天内完成了现代 Cookie 盗窃图片描述。对描述进行了多种微语言特征分析。回顾性查阅病历以确定是否存在认知障碍。
与对照组相比，急性右脑卒中患者生成的内容单元、总音节和左右内容单元比例较低，表明信息量不足。存在认知障碍与生成的内容单元较少有关。
多种微语言话语特征的测量方法将右脑卒中患者与对照组区分开来，突出了连贯话语在数量和质量上的差异。这些发现进一步强调了认知技能和话语表现之间的贡献和相关性。未来的工作需要评估特定认知领域与话语生成之间的关系，以及在中风康复过程中对话语生成的纵向变化进行研究。
