Three groups of children rated firstly as overactive and distractible, secondly as distractible and thirdly as low on both activity and distractibility were examined in a visual search task with three levels of display load: two, three and four items. The children were tested twice in two conditions of stimulus visibility to examine the encoding stage of the model used here. The experimental results reject the hypothesis that an encoding deficit or data limitation may explain the attentional performance of either hyperactive or somewhat hyperactive subjects. They suggest, rather, that a trade-off in speed and accuracy may be evident in (the) hyperactives.
三组儿童，第一组被评定为多动且注意力分散，第二组被评定为注意力分散，第三组被评定为活动水平和注意力分散程度均较低。对他们进行了一项视觉搜索任务测试，该任务有三种显示负荷水平：两项、三项和四项。在刺激可见性的两种条件下对儿童进行了两次测试，以检验此处使用的模型的编码阶段。实验结果否定了这样一种假设，即编码缺陷或数据限制可以解释多动或有点多动的受试者的注意力表现。相反，实验结果表明，多动者在速度和准确性之间可能存在权衡。
