Adult age differences in visual search were examined under manipulations of target set consistency (fixed versus varied), response complexity (2 versus 4 sorting categories), display size (1, 4, or 8 letters/card), and sessions (2). Mean card sorting times of 20 young (mean = 22 years) and 20 elderly (mean = 62 years) adults were compared. Significant main effects of age, complexity, consistency, sessions, and display size were obtained. A consistent target set facilitated search independent of response complexity. As predicted, significant interactions indicated that age differences in search were eliminated under the fixed set procedure but not under the varied set procedure.
在目标集一致性（固定与变化）、反应复杂性（2 与 4 个分类类别）、显示大小（1、4 或 8 个字母/卡片）以及实验次数（2 次）的操作条件下，研究了成年人视觉搜索中的年龄差异。比较了 20 名年轻人（平均年龄 = 22 岁）和 20 名老年人（平均年龄 = 62 岁）的平均卡片分类时间。获得了年龄、复杂性、一致性、实验次数和显示大小的显著主效应。一致的目标集有助于搜索，且与反应复杂性无关。正如预测的那样，显著的交互作用表明，在固定集程序下搜索中的年龄差异被消除，但在变化集程序下未被消除。
