Although episodic memory is the primary concern in individuals with mild cognitive impairment (MCI), other cognitive functions may also be affected, including language. Language impairment in individuals with MCI has been attributed primarily to the breakdown of semantic representations, difficulties in accessing semantic information, and the weakening of executive functions. However, in most prior studies of word processing in individuals with MCI, researchers have used measures focused on noun production.
To investigate how verb production tasks might aid in detecting cognitive impairment in individuals with MCI.
We compared the performance of 45 individuals with MCI and 45 healthy controls on action naming and action fluency tasks.
In the action naming task, the performance of participants with MCI was significantly impaired compared to healthy controls in terms of total score, the number of semantic errors produced, and the use of generic terms. In the action fluency task, participants with MCI produced significantly fewer verbs, fewer clusters, and fewer switches than healthy controls.
The results of our study emphasize the utility of verb production tasks in the identification of cognitive impairment in individuals with MCI and provide evidence of the importance of including action naming and action fluency tasks in the assessment of individuals with MCI.
尽管情景记忆是轻度认知障碍（MCI）患者的主要关注问题，但其他认知功能也可能受到影响，包括语言。MCI患者的语言障碍主要归因于语义表征的崩溃、获取语义信息的困难以及执行功能的减弱。然而，在大多数先前关于MCI患者词汇加工的研究中，研究人员使用的测量方法主要集中在名词生成上。
探讨动词生成任务如何有助于检测MCI患者的认知障碍。
我们比较了45名MCI患者和45名健康对照在动作命名和动作流畅性任务上的表现。
在动作命名任务中，MCI患者在总分、产生的语义错误数量和通用术语的使用方面，与健康对照相比表现显著受损。在动作流畅性任务中，MCI患者产生的动词、聚类和转换比健康对照显著更少。
我们的研究结果强调了动词生成任务在识别MCI患者认知障碍中的作用，并为在MCI患者评估中纳入动作命名和动作流畅性任务的重要性提供了证据。
