We investigated the representation and breakdown of verb knowledge employing different syntactic and semantic classes of verbs in a group of individuals with probable Alzheimer's Disease (pAD). In an action naming task with coloured photographs (Fiez & Tranel, 1997. Standardized stimuli and procedures for investigating the retrieval of lexical and conceptual knowledge for action. Memory and Cognition, 25(4), 543-569. https://doi.org/10.3758/BF03201129), pAD individuals were impaired for naming actions compared to objects. Verb tense was also affected, with simple-past (e.g., chopped) being more difficult to name than the gerundial form (e.g., chopping). Employing action-naming with short movies depicting events and states, we contrasted three verb classes based on their hypothetical structural and semantic/conceptual properties: argument structure, thematic structure, and conceptual templates. The three classes were: causatives (peel), verbs of perception (hear), and verbs of motion (run) Overall, results suggest that individuals with pAD are selectively impaired for verb tense and thematic assignment, but not conceptual-template complexity. Methodologically, we also show that dynamic scenes are more ecologically valid than static scenes to probe verb knowledge in AD.

阿尔茨海默病中特定类别的动词语义缺陷：来自静态和动态动作命名的证据

我们调查了一组可能患有阿尔茨海默病 (pAD) 的个体中使用不同句法和语义类别的动词知识的表示和分解。在带有彩色照片的动作命名任务中（Fiez & Tranel，1997。标准化刺激和调查检索动作的词汇和概念知识的程序。Memory and Cognition, 25(4), 543-569. https://doi. org/10.3758/BF0​​3201129)，与物体相比，pAD 个体的命名行为受损。动词时态也受到影响，简单过去时（例如，切碎）比动名词形式（例如切碎）更难命名。在描述事件和状态的短片中使用动作命名，我们根据假设的结构和语义/概念属性对比了三个动词类：论证结构、主题结构和概念模板。这三类是：原因（剥离）、感知动词（听到）和运动动词（跑） 总的来说，结果表明 pAD 个体在动词时态和主题分配方面有选择性受损，但概念模板复杂性没有。在方法上，我们还表明动态场景比静态场景在生态上更有效，以探索 AD 中的动词知识。
