摘要

这项研究旨在调查健康老年人对痴呆症相关词语的反应,以及早期痴呆症患者在20个月内的反应变化。研究采用了一项情绪化 Stroop 任务,用颜色命名痴呆症相关词语,作为痴呆症隐性认知的指标。共有 24 名痴呆症患者和 24 名健康老年人完成了情感 Stroop 任务(T1)。痴呆症患者在 12 个月(T2)和 20 个月(T3)后再次完成同样的任务。对痴呆症患者的情绪 Stroop 表现与根据 T1 和 T2 详细访谈得出的明确意识评分进行了对比。健康老年人和痴呆症患者对痴呆症相关词语的反应时间明显长于对中性词的反应时间。而痴呆症患者在 T3 阶段则没有这种效应。情绪性 Stroop 效应的下降与 MMSE 测量的认知能力下降无关。随着时间的推移,显性认知的评分没有明显变化。显性意识与隐性意识之间没有关联。早期痴呆症患者对病情的隐性意识非常明显,即使在显性意识减弱的情况下也能引起隐性意识。随着时间的推移,痴呆症患者对痴呆症相关词语的情感斯特罗普效应似乎会下降,而与MMSE评分的变化无关,这表明随着时间的推移,内隐意识会逐渐消失。

Exploring longitudinal changes in implicit awareness of dementia: An investigation of the emotional Stroop effect in healthy ageing and mild dementia

The aim of the study was to investigate responses to dementia-relevant words in healthy older people and to investigate changes in response over 20-months in people with early-stage dementia. An emotional Stroop task, using colour-naming dementia-relevant words, was used as an indicator of implicit awareness of dementia. Overall, 24 people with dementia and 24 healthy older people completed an emotional Stroop task (T1). People with dementia completed the same task again after 12 (T2) and 20 (T3) months. For people with dementia emotional Stroop performance was contrasted with ratings of explicit awareness based on a detailed interview at T1 and at T2. For healthy older people and people with dementia response times to dementia-relevant words were significantly longer than those for neutral words. The effect was absent for people with dementia at T3. This decline in the emotional Stroop effect was not associated with cognitive decline as measured by the MMSE. Ratings of explicit awareness showed no significant change over time. There was no association between explicit awareness and implicit awareness. Implicit awareness of the condition is evident in early-stage dementia and can be elicited even where there is reduced explicit awareness. The emotional Stroop effect for dementia-relevant words in people with dementia appears to decline over time, independently of changes in MMSE score, suggesting that implicit awareness fades as time progresses.

期刊介绍: The Journal of Neuropsychology publishes original contributions to scientific knowledge in neuropsychology including: • clinical and research studies with neurological, psychiatric and psychological patient populations in all age groups • behavioural or pharmacological treatment regimes • cognitive experimentation and neuroimaging • multidisciplinary approach embracing areas such as developmental psychology, neurology, psychiatry, physiology, endocrinology, pharmacology and imaging science The following types of paper are invited: • papers reporting original empirical investigations • theoretical papers; provided that these are sufficiently related to empirical data • review articles, which need not be exhaustive, but which should give an interpretation of the state of research in a given field and, where appropriate, identify its clinical implications • brief reports and comments • case reports • fast-track papers (included in the issue following acceptation) reaction and rebuttals (short reactions to publications in JNP followed by an invited rebuttal of the original authors) • special issues.
