2项研究考察了知觉负荷对视觉选择性注意的调节作用。在研究1中，儿童和年轻的成年人搜索显示不同的设置大小两侧不相关的干扰。在高负荷而非低负荷的条件下，儿童的表现与成人一样有效，这表明早期选择涉及迅速成熟的神经系统，而晚期选择涉及较晚成熟的系统。在研究二中，测试了4个年龄组，并在空白位置设置了位置标记，以检查知觉分组效应。研究1的模式在所有年龄组中重复，早期选择的发生在较低的负荷为年幼的儿童。总体而言，儿童在较低的负荷下开始早期选择，以弥补不成熟的前系统干扰控制过程。
The moderating effect of perceptual load on visual selective attention was examined in 2 studies. In Study 1, children and young adults searched displays of varying set size flanked by irrelevant distractors. Children's performance was as efficient as adults' under conditions of high but not low loads, suggesting that early selection engages rapidly maturing neural systems and late selection engages later-maturing systems. In Study 2, 4 age groups were tested, and place markers were set at empty locations to examine perceptual grouping effects. Study 1's pattern was replicated in all age groups, with onset of early selection occurring at lower loads for younger children. Overall, children initiated early selection at lower loads to compensate for immature anterior-system interference control processes.
