Previous work found that single-session focused attention meditation (FAM) enhanced motor sequence learning through increased cognitive control as a mechanistic action, although electrophysiological correlates of sequence learning performance following FAM were not investigated. We measured the persistent frontal N2 event-related potential (ERP) that is closely related to cognitive control processes and its ability to predict behavioural measures. Twenty-nine participants were randomised to one of three conditions reflecting the level of FAM experienced prior to a serial reaction time task (SRTT): 21 sessions of FAM (FAM21, N = 12), a single FAM session (FAM1, N = 9) or no preceding FAM control (Control, N = 8). Continuous 64-channel EEG were recorded during SRTT and N2 amplitudes for correct trials were extracted. Component amplitude, regions of interests, and behavioural outcomes were compared using mixed effects regression models between groups. FAM21 exhibited faster reaction time performances in majority of the learning blocks compared to FAM1 and Control. FAM21 also demonstrated a significantly more pronounced N2 over majority of anterior and central regions of interests during SRTT compared to the other groups. When N2 amplitudes were modelled against general learning performance, FAM21 showed the greatest rate of amplitude decline over anterior and central regions. The combined results suggest that FAM training provided greater cognitive control enhancement for improved general performance, and less pronounced effects for sequence-specific learning performance compared to the other groups. Importantly, FAM training facilitates dynamic modulation of cognitive control: lower levels of general learning performance was supported by greater levels of activation, whilst higher levels of general learning exhibited less activation.

注意力集中冥想可增强运动序列表现期间的认知控制：来自N2皮质诱发电位的证据。
先前的工作发现，尽管没有研究过FAM后序列学习表现的电生理相关性，但单节时集中注意力冥想（FAM）通过增加认知控制作为一种机械动作来增强了运动序列学习。我们测量了与认知控制过程及其预测行为测评能力密切相关的持续性额叶N2事件相关电位（ERP）。29名参与者被随机分配到三个条件之一，这些条件反映了在连续反应时间任务（SRTT）之前经历的FAM水平：21次FAM（FAM21，N = 12），单个FAM会议（FAM1，N = 9 ）或没有前面的FAM控制（Control，N = 8）。在SRTT期间记录了连续的64通道EEG，并提取了N2振幅以进行正确的试验。分量幅度 使用组之间的混合效应回归模型比较了感兴趣的区域和行为结果。与FAM1和Control相比，FAM21在大多数学习模块中表现出更快的反应时间性能。与其他组相比，在SRTT期间，FAM21还显示出在大部分前，中部利益区域中N2的含量明显更高。当针对一般学习性能对N2幅度进行建模时，FAM21在前部和中部区域显示出最大的幅度下降率。综合结果表明，与其他组相比，FAM训练提供了更大的认知控制增强，从而改善了总体表现，而对序列特异性学习表现的影响则较小。重要的是，FAM培训有助于认知控制的动态调节：
