Adult age differences in the mode of allocation of visual attention were investigated, using a visual search task with a circular display containing one target letter and seven distractor letters. In two experiments, a total of 56 younger adults (M = 20 years) and 56 older adults (M = 66 years) searched for a target appearing with equal probability at one of two cued locations. The first cue appeared 115 msec before display onset, and the second cue appeared with display onset; distance between the two cued locations was varied. Target identification performance indicated that attention was inertial, in that reaction time for second-cued targets was related either to the area of the portion of the visual field containing possible target locations or to the mean path length of a serial self-terminating search. There were no age-related decrements in the allocation of visual attention.
研究了成年人在视觉注意力分配模式上的年龄差异，采用了一种视觉搜索任务，其圆形显示屏上包含一个目标字母和七个干扰字母。在两项实验中，共有56名年轻成年人（平均年龄M = 20岁）和56名年长成年人（平均年龄M = 66岁）在两个提示位置之一搜索以相等概率出现的目标。第一个提示在显示屏开始前115毫秒出现，第二个提示与显示屏同时出现；两个提示位置之间的距离是变化的。目标识别表现表明注意力具有惯性，即第二个提示目标的反应时间与包含可能目标位置的视野部分的面积或串行自终止搜索的平均路径长度有关。在视觉注意力分配方面没有与年龄相关的下降。
