Abstract

Objective: The present study aims to assess the relationship between quantitative measures of connected speech production and performance in confrontation naming in early post-stroke aphasia (8-14 days post-stroke). Method: We collected connected speech samples elicited by a picture description task and administered a confrontation naming task to 20 individuals with early post-stroke aphasia and 20 healthy controls. Transcriptions were made in compliance with the CHAT format guidelines. Several micro- (i.e. duration, total number of words, words per minute, mean length of utterances, ratio of open- to closed-class words and noun-to-verb ratio, VOC-D, repetitions, self-corrections, and phonological and semantic errors) and macrolinguistic (i.e. informativeness and efficiency) measures were extracted. Results: We provide evidence for the presence of impairments in an array of micro- and macrolinguistic measures of speech in individuals with early post-stroke aphasia. We show that in the patient group, confrontation naming abilities most strongly relate to informativeness in a picture description task. Conclusion: Our findings contribute to a better understanding of the relationship between performance in confrontation naming and in connected speech production in the first days after stroke onset and also suggest that discourse analysis may provide unique, possibly more complex information.

早期脑卒中后失语症患者在对抗命名和图片描述中的找词能力。
目的:本研究旨在评估脑卒中后失语症早期(脑卒中后8-14天)关联言语产生的定量测量与对抗命名表现的关系。方法:对20例脑卒中后早期失语症患者和20例健康对照者进行对照命名。转录是按照CHAT格式指引进行的。提取了几个微观指标(即持续时间、总字数、每分钟字数、平均话语长度、开放类与封闭类字数之比、名动比、VOC-D、重复、自我纠正、语音和语义错误)和宏观指标(即信息量和效率)。结果:我们提供的证据表明,早期中风后失语症患者在言语的一系列微观和宏观语言测量中存在障碍。我们发现,在患者组中,对抗命名能力与图片描述任务中的信息性关系最为密切。结论:我们的研究结果有助于更好地理解中风发作后第一天的对抗命名表现和关联言语产生之间的关系,也表明语篇分析可能提供独特的,可能更复杂的信息。
