摘要：
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.
