年轻（19-27岁）和老年人（60-82岁）的成年人进行了一个字母搜索任务，其中一个颜色单例是无信息（基线条件）或高度信息（引导条件）关于目标位置。在引导条件下，两个年龄组表现出显着减少反应时间（RT）的单目标，相对于基线条件，以及RT增加nonsingleton目标。作者得出结论，在个人展示的物理结构等同的条件下，自上而下的注意力引导至少对老年人和年轻人一样有效。
Younger (19-27 years of age) and older (60-82 years of age) adults performed a letter search task in which a color singleton was either noninformative (baseline condition) or highly informative (guided condition) regarding target location. In the guided condition, both age groups exhibited a substantial decrease in response time (RT) to singleton targets, relative to the baseline condition, as well as an increase in RT to nonsingleton targets. The authors conclude that under conditions that equate the physical structure of individual displays, top-down attentional guidance can be at least as effective for older adults as for younger adults.
