Sense of agency(SoA), the fundamental feeling of control over our actions and their consequences, may show key developmental changes during adolescence. We examined SoA in childhood (9-10), mid-adolescence (13-14), late-adolescence (18-20) and adulthood (25-28) using two tasks (Libet Clock and Stream of Letters). SoA was implicitly indexed by intentional binding that reflects the agency effect on action-outcome temporal association. We found age effects on the sub-processes in both tasks. In the Libet Clock task, where performance was more reliable, we observed a U-shaped developmental trajectory of intentional binding suggesting an adolescent-specific reduction in the experience of control. This study provides evidence for the developmental effects on the implicit agency experience and suggests adolescence as a critical period. We discuss the possible implications of these findings.
主体感（SoA）是指对自身行为及其后果的基本控制感，它可能在青春期经历关键的发展变化。我们使用两个任务（Libet 时钟和字母流）在儿童期（9-10 岁）、中期青春期（13-14 岁）、晚期青春期（18-20 岁）和成年期（25-28 岁）中考察了 SoA。主体感通过意向绑定来隐含地反映出对行为-结果时间关联的影响。我们发现两个任务中的子过程都存在年龄效应。在 Libet 时钟任务中，由于表现更可靠，我们观察到意向绑定的 U 形发展轨迹，表明青少年时期控制感的体验会出现特定的减少。这项研究为主体感体验的发展效应提供了证据，并表明青春期是一个关键时期。我们讨论了这些发现的可能意义。
