4-5 岁和 9-10 岁的儿童以及大学年龄的成年人接受了两项视觉掩蔽任务的测试。第一个任务要求 Ss 识别速动镜呈现的条是水平的还是垂直的。第二个任务也使用刺激的速速镜呈现，要求 Ss 在垂直（或水平）条的矩阵中定位水平（或垂直）条。在这两项任务中，后向掩蔽比前向掩蔽产生更大的干扰，并且后向和前向掩蔽引起的干扰量随着年龄的增加而减少。仅在定位任务中发现了年龄与掩蔽条件的交互作用，并且反映出最年轻组的后向和前向掩蔽条件之间的差异比年长组大得多。基于这些发现和其他考虑，得出的结论是，只有在可能需要视觉搜索的定位任务中，年轻群体的视觉处理速度才较慢。
Children, 4-5 and 9-10 years old, and college-age adults were tested on two visual masking tasks. The first task required the Ss to identify whether a tachistoscopically presented bar was horizontal or vertical The second task, also using tachistoscopic presentation of stimuli, required Ss to locate a horizontal (or vertical) bar in a matrix of vertical (or horizontal) bars. In both tasks, backward masking produced greater disruption than did forward masking, and the amount of disruption induced by both backward and forward masking decreased as age increased. An Age by Masking Condition interaction was found only in the location task and reflected a much greater difference between backward- and forward-masking conditions for the youngest group than for the older groups. On the basis of these findings and other considerations, it was concluded that only in the location task, which presumably required visual search, was the speed of visual processing slower in the younger group.
