Six- to 8-year-olds, 10- to 12-year-olds, and adults (N = 108) performed the Simon task by reaching to targets on a digital display. The spatial and temporal characteristics of their movements were used to assess how two key processes underlying cognitive control-a threshold adjustment process and a controlled selection process-unfold over the course of a response (within-trial dynamics), are modulated by recent experience (cross-trial dynamics), and contribute to age-related gains in control (developmental dynamics). The results indicate that the controlled selection process undergoes a more protracted development than the threshold adjustment process. The results also shed light on a prominent debate concerning the cross-trial dynamics of control by supporting the feature integration account over the conflict adaptation account.
6 至 8 岁、10 至 12 岁和成年人（N=108）通过在数字显示屏上伸手触及目标来完成西蒙任务。他们的运动的空间和时间特征用于评估认知控制的两个关键过程——阈值调整过程和受控选择过程——如何在响应过程中展开（在试内动态），以及如何受到近期经验的调节（在试间动态），并有助于控制的年龄相关收益（发展动态）。结果表明，受控选择过程的发展比阈值调整过程更为漫长。结果还通过支持特征整合理论而非冲突适应理论，为控制的在试间动态方面的一个重要争论提供了线索。
