选择能力(选择几个竞争的语义和/或词汇表示的反应)进行了测试,在21名参与者与阿尔茨海默氏病(AD)和28名对照参与者,以帮助澄清AD的语义障碍的性质。选择要求操纵3个任务(词汇流畅性,比较,动词生成)。在每一种情况下,高选择性条件需要从竞争性替代品中进行反应选择,而低选择性条件则减少了选择的需要。AD患者在所有任务的高选择条件下都不成比例地受损,即使这种条件更容易。动词生成的选择赤字是明显的,只有相对于nonspeeded控制。总体结果表明,受损的语义选择能力在AD,这可能有助于在一些语义任务的性能差。(PsycInfo数据库记录(c)2023阿帕,保留所有权利)
Selection ability (selecting a response from several competing semantic and/or lexical representations) was tested in 21 participants with Alzheimer's disease (AD) and 28 control participants to help clarify the nature of semantic impairments in AD. Selection demands were manipulated in 3 tasks (lexical fluency, comparison, and verb generation). In each, high-selection conditions required response selection from competing alternatives, whereas low-selection conditions had a reduced need for selection. Patients with AD were disproportionately impaired on the high-selection conditions of all tasks, even when this condition was easier. Selection deficits on verb generation were evident only relative to nonspeeded controls. Overall results indicate impaired semantic selection abilities in AD, which may contribute to poor performance on some semantic tasks.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
