预测和准备未来事件的能力被认为是认知控制的关键。认知控制的主流理论认为，发育中的系统仅仅是成人系统的一个较弱版本，随着时间的推移逐渐增强。使用AX连续表现任务（AX- cpt）结合高分辨率瞳孔测量，我们发现8岁的儿童在主动使用认知控制方面与成人相似，而3.5岁的儿童表现出一种质的不同，反应性形式的认知控制，只在事件展开时做出反应，并在需要时从记忆中检索信息。这些结果表明需要重新考虑认知控制的起源和跨领域儿童行为的基础。
The capacity to anticipate and prepare for future events is thought to be critical for cognitive control. Dominant accounts of cognitive control treat the developing system as merely a weaker version of the adult system, progressively strengthening over time. Using the AX Continuous Performance Task (AX-CPT) in combination with high-resolution pupillometry, we find that whereas 8-year-old children resemble adults in their proactive use of cognitive control, 3.5-year-old children exhibit a qualitatively different, reactive form of cognitive control, responding to events only as they unfold and retrieving information from memory as needed in the moment. These results demonstrate the need to reconsider the origins of cognitive control and the basis for children's behaviors across domains.
