在早期发育过程中，有助于注意力和相关技能的神经区域发生了重大变化。虽然学龄前儿童通常难以进行连续的表现测试，但目前尚不清楚这主要是由于无法选择性地做出反应还是无法保持注意力。一组52名3.5至5.5岁的儿童进行2警戒型反应时任务。任务包括短时间，连续呈现视觉刺激跨越几个短块。在4.5岁以下的儿童中，46%的儿童不能协调必要的任务要求，而那些能协调的儿童比年龄较大的儿童犯更多的遗漏错误。在所有儿童的反应时间任务中，积极参与度很高。这些结果表明，必要的警惕任务，特别是快速反应启动和反应选择的技能，仍然是在学龄前出现，但可以充分测量后4.5岁。
During early development, significant changes occur in the neural regions that subserve attention and related skills. Although preschoolers typically have difficulty performing continuous performance tests, it is not clear if this is primarily due to an inability to selectively respond or an inability to maintain attention. A group of 52 children between 3.5 and 5.5 years of age performed 2 vigilance-type reaction time tasks. The tasks included short duration, continuously presented visual stimuli across several short blocks. Among the children under 4.5 years of age, 46% were unable to coordinate the necessary task demands, and those who could made significantly more omission errors than the older children. Active engagement was high during the reaction time tasks for all children. These results suggest that the skills necessary for vigilance tasks, particularly speeded response initiation and response selection, are still emerging during the preschool years but can be adequately measured after 4.5 years of age.
