目的失语症（PWA）患者选择性注意的完整性目前尚不清楚。选择性注意在日常交际中是必不可少的，抑制是选择性注意的重要组成部分。本研究探讨了在PWA和神经系统健康（HC）的对照组中，在口语单词生产过程中的抑制成分-有意和反应性抑制。故意抑制是能够抑制干扰的反应，反应性抑制是延迟重新激活以前抑制item.Methodnineteen PWA和20年龄和教育相匹配的HC参加了Stroop口语单词生产任务。这项任务允许检查有意和反应性抑制唤起和比较干扰，促进，和负启动效应在不同的context.ResultsAlthough两组表现出有意抑制，PWA表现出显着更多的干扰效果。PWA没有表现出明显的易化效应。HC表现出显著的反向易化效应。两组都没有表现出显着的反应性抑制的证据，虽然这两组表现出类似的个人variability.ConclusionsThese results强调的挑战干扰呈现为PWA在口语词生产，减少故意抑制。虽然反应性抑制在PWA和HC之间没有区别，但PWA在语言任务中表现出对上下文信息的整合和适应困难。
PurposeThe integrity of selective attention in people with aphasia (PWA) is currently unknown. Selective attention is essential for everyday communication, and inhibition is an important part of selective attention. This study explored components of inhibition—both intentional and reactive inhibition—during spoken-word production in PWA and in controls who were neurologically healthy (HC). Intentional inhibition is the ability to suppress a response to interference, and reactive inhibition is the delayed reactivation of a previously suppressed item.MethodNineteen PWA and 20 age- and education-matched HC participated in a Stroop spoken-word production task. This task allowed the examination of intentional and reactive inhibition by evoking and comparing interference, facilitation, and negative priming effects in different contexts.ResultsAlthough both groups demonstrated intentional inhibition, PWA demonstrated significantly more interference effects. PWA demonstrated no significant facilitation effects. HC demonstrated significant reverse facilitation effects. Neither group showed significant evidence of reactive inhibition, though both groups showed similar individual variability.ConclusionsThese results underscore the challenge interference presents for PWA during spoken-word production, indicating diminished intentional inhibition. Although reactive inhibition was not different between PWA and HC, PWA showed difficulty integrating and adapting to contextual information during language tasks.
