The dissociation between the processing of verbs and nouns has been debated in light of the Embodied Cognition Theory (EC). The objective of this paper is to verify how action and verb processing deficits of PD patients are modulated by different tasks with different cognitive demands. Action and object lexical-semantic processing was evaluated in patients with Parkinson's Disease (PD) and cognitively healthy controls through three different tasks (verbal fluency, naming and semantic association). Compared to controls, PD patients presented worse performance in naming actions and in the two semantic association tasks (action/object). Action verbal fluency performance was significantly associated with PD severity whereas object semantic association deficits and noun verbal fluency scores were associated to lower scores in measures of global cognitive functioning. Our data suggest that semantic deficits are related to the type of cognitive processing and this is in the line with more flexible EC accounts.
动词和名词加工之间的分离一直是根据具身认知理论（EC）进行讨论的。本文的目的是验证帕金森病（PD）患者的动作和动词加工缺陷如何受到具有不同认知需求的不同任务的调节。通过三项不同任务（言语流畅性、命名和语义联想）对帕金森病（PD）患者和认知健康的对照组进行动作和客体词汇语义加工评估。与对照组相比，PD患者在动作命名以及两项语义联想任务（动作/客体）中的表现更差。动作言语流畅性表现与PD严重程度显著相关，而客体语义联想缺陷和名词言语流畅性得分与整体认知功能测量中的较低分数相关。我们的数据表明，语义缺陷与认知加工类型有关，这与更灵活的具身认知理论观点一致。
