轻度阿尔茨海默病（AD）和健康正常对照（NC）老年人的个人进行了不同的设置版本的斯滕贝格记忆扫描任务与设置大小1，2，3和4。AD组（N=23）的反应时间（RT）比NC组（N=38）更慢，变化更大。RT组之间的差异更大的NO比是的反应。RT和集合大小之间的线性关系不像NC组那样强。然而，与受试者较少的早期研究相比，AD和健康老年人的参与者在扫描记忆集中的项目的速度上没有差异。
Individuals with mild Alzheimer’s Disease (AD) and healthy normal control (NC) older adults performed a varied-set version of the Sternberg memory-scanning task with Set Sizes 1, 2, 3, and 4. The AD group (N=23) had slower and more variable reaction times (RT) than the NC group (N=38). RT differences between groups were bigger for NO than for YES responses. The linear relationship between RT and set size was not as strong for the AD group as for the NC group. However, in contrast to earlier studies with fewer subjects, participants with AD and healthy older individuals did not differ in the rate at which they scan items in the memory set.
