儿童在向学校过渡的过程中经历了重要的认知控制改善。本研究考察了4 - 5岁儿童（n = 17）和7 - 8岁儿童（n = 22）主动部署认知控制的能力。孩子们执行了一个提示任务切换范式，给他们一个提示，指示他们应该使用哪个属性、颜色或形状来对即将到来的刺激进行分类。在提示和刺激下，我们分析了两个事件相关电位：P2和P3，分别反映认知控制的感觉和注意成分的正峰。根据提示，我们还分析了正慢波，索引工作记忆参与。我们预测，在需要切换任务的切换试验中，主动控制会导致更大的线索- p3振幅，反映出对切换需要的识别，以及更大的慢波振幅，反映出在线索后延迟中对新任务集的维护。这一模式在两个年龄组中都观察到了。在刺激下，在转换试验中，两个年龄组的刺激- p2潜伏期都较短，与加工促进一致。这些结果表明，4-5岁和7 - 8岁的儿童都积极参与认知控制。然而，年龄较大的儿童表现出更好的表现和更大的线索- p2振幅，这表明在儿童中期更有效的主动控制参与。
Children experience important cognitive control improvements in the transition to school. This study examined 4–5-year-olds’ (n = 17) and 7–8-year-olds’ (n = 22) ability to proactively deploy cognitive control. Children performed a cued task-switching paradigm presenting them with a cue indicating which attribute, color or shape, they should use to sort the upcoming stimulus. Following both cue and stimulus, we analyzed two event-related potentials: the P2 and P3, positive peaks reflecting sensory and attentional components of cognitive control, respectively. Following the cue, we also analyzed a positive slow-wave, indexing working memory engagement. We predicted that on switch trials, which required switching tasks, proactive control would result in larger cue-P3 amplitudes, reflecting recognition of the need to switch, and larger slow-wave amplitudes, reflecting maintenance of the new task-sets over the post-cue delay. This pattern was observed in both age groups. At the stimulus, in switch trials, both age groups had shorter stimulus-P2 latencies, consistent with processing facilitation. These results suggest that both 4–5- and 7–8-year-olds engaged cognitive control proactively. Older children, however, demonstrated better performance and larger cue-P2 amplitudes, suggesting more effective proactive control engagement in middle childhood.
