Emotional and traditional Stroop effects were contrasted in individuals with Alzheimer's disease (AD) and age-equated, non-demented individuals to examine (a) differences in the speed of processing emotional versus neutral words; and (b) the extent to which the emotional valence influences interference effects. Individuals with moderate AD experienced larger traditional Stroop interference effects than did healthy elderly or individuals with mild AD. Emotional Stroop effects were evident among individuals with moderate AD and significantly greater than elderly and individuals with mild AD who exhibited minimal effects. For negative words, significant differences were only observed between individuals with moderate AD and healthy elderly. Emotional Stroop effects among individuals with AD were not statistically different for positive and negative words. The impact of stimulus intensity level and AD-associated changes to the prefrontal cortex and amygdala on emotional Stroop effects requires further investigation.

阿尔茨海默氏型痴呆的抑制性控制和情感价处理。

在患有阿尔茨海默氏病（AD）的人和与年龄相同的无痴呆者中，对情绪和传统Stroop效应进行了对比，以研究（a）处理情感词与中性词的速度差异；（b）情感价对干扰作用的影响程度。与健康的老年人或轻度AD患者相比，中度AD患者具有更大的传统Stroop干扰效应。情绪性Stroop效应在中度AD患者中很明显，并且显着大于老年人和中度AD患者，后者的影响最小。否定的话，仅在中度AD患者和健康老年人之间观察到显着差异。对于积极和消极的单词，AD个体之间的情绪Stroop效应在统计学上没有差异。刺激强度水平和AD相关变化对额叶前额叶皮层和杏仁核对情绪Stroop效应的影响需要进一步研究。
