反应抑制是一种关键的执行功能，在成年早期继续发展，与支持它的潜在前额叶区域的成熟过程并行。目前的研究在一个大样本（N = 120）中检查了在视觉Go/No-Go任务中反应抑制的行为和神经生理学相关性，该样本由20岁出头（19-21岁）、20岁中期（23-27岁）和30岁出头（28-42岁）的参与者组成。与30岁出头的人相比，两组年轻人的准确率更低，反应时间更短，反应更早。与30岁早期相比，20岁早期的冲动行为倾向表现为N2潜伏期延迟，P2和P3振幅降低，并且与冲动等人格特征呈年龄依赖性。结果表明，在大约25岁之前，反应抑制可能不会完全发展，因为主要前额叶认知控制网络的完善遵循整个青年成年期的长期发展轨迹。
Response inhibition, a key executive function, continues to develop in early adulthood in parallel with maturational processes of the underlying prefrontal regions known to support it. The current study examined behavioral and neurophysiological correlates of response inhibition during a visual Go/No-Go task in a large sample (N = 120) comprised of participants in their Early 20s (ages 19–21), Mid 20s (ages 23–27), and Early 30s (ages 28–42). The two younger groups had lower accuracy, shorter reaction times, and made more premature responses compared to Early 30s. These impulsive behavioral tendencies were reflected in a delayed N2 latency and reduced P2 and P3 amplitudes for Early 20s compared to Early 30s and were associated with personality traits such as impulsivity in an age-dependent manner. The results suggest that response inhibition may not develop fully before the approximate age of 25, as the refinement of the primarily prefrontal cognitive control network follows a protracted developmental trajectory throughout young adulthood.
