摘要

实验证据表明,额下回(IFG)处理情感/情感特征,这些特征对阐明社会群体的知识至关重要,并且社会概念的知识存储在前颞叶(ATL)中,其中已经证明了IFG和ATL之间的功能失调的连接。PD患者(N = 20) 和健康对照组(HC,N = 16) 在语义启动范式中,被赋予了一项词汇决策任务:主要目标包括144个单词和144个假名,每个单词前面都有三种类型的素数(“动物”、“事物”和“人”)。在这288个主要目标中,48个是一致的(同一类别),96个是不一致的(不同类别)。在48个一致的主要目标中,24个表示社会项目,24个非社会项目。因此,获得了四种类型的试验:一致的社会试验;一致的非社会性;不协调的社会;不协调的非社会性。所有组对一致目标词的识别均优于不一致目标词。PD中保留了语义启动效应;然而,在社会项目方面,PD的准确率明显低于HC。两组在非社会项目上没有差异。PD中表示社会群体的单词处理受损可能是由于在获取表征社会群体概念知识的情感/情感特征方面受损,因为IFG和ATL之间的功能脱节。

Impaired processing of conspecifics in Parkinson's disease.

Experimental evidence indicates that the inferior frontal gyrus (IFG) processes emotional/affective features crucial to elaborate knowledge about social groups and that knowledge of social concepts is stored in the anterior temporal lobe (ATL).We investigated whether knowledge about social groups is impaired in Parkinson's disease (PD), in which dysfunctional connectivity between IFG and ATL has been demonstrated.PD patients (N = 20) and healthy controls (HC, N = 16) were given a lexical decision task in a semantic priming paradigm: the prime-targets included 144 words and 144 pseudowords, each preceded by three types of prime ("animals," "things," "persons"). Out of these 288 prime-targets, forty-eight were congruent (same category) and 96 incongruent (different category). Out of 48 congruent prime-targets, 24 denoted social items and 24 nonsocial items. Thus, four types of trials were obtained: congruent social; congruent nonsocial; incongruent social; incongruent nonsocial.Congruent target-words were recognized better than incongruent target-words by all groups. The semantic priming effect was preserved in PD; however, accuracy was significantly lower in PD than in HC in social items. No difference emerged between the two groups in nonsocial items.Impaired processing of words denoting social groups in PD may be due to impairment in accessing the affective/emotional features that characterize conceptual knowledge of social groups, for the functional disconnection between the IFG and the ATL.

期刊介绍: pplied Neuropsychology-Adult publishes clinical neuropsychological articles concerning assessment, brain functioning and neuroimaging, neuropsychological treatment, and rehabilitation in adults. Full-length articles and brief communications are included. Case studies of adult patients carefully assessing the nature, course, or treatment of clinical neuropsychological dysfunctions in the context of scientific literature, are suitable. Review manuscripts addressing critical issues are encouraged. Preference is given to papers of clinical relevance to others in the field. All submitted manuscripts are subject to initial appraisal by the Editor-in-Chief, and, if found suitable for further considerations are peer reviewed by independent, anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
