本研究探讨了在技能学习的言语-认知阶段与运动表现相关的脑电活动的变化。参与者（n = 14）被要求练习一个顺序的手指敲击任务。EEG活动记录之前和之后的短期实践，在手指轻敲和两个控制条件。计算θ（4-8 Hz）、慢α（8-10 Hz）、快α（10-12 Hz）、慢β（1220 Hz）和快β（20-28 Hz）带宽的EEG功率（Fz、Cz、Pz、T3、T4）和相干性（T3-Fz、T4-Fz、Fz-Cz、Fz-Pz）。运动成绩的变化在练习的最初阶段是迅速的，然后缓慢，雅阁实践的规律。这些变化伴随着增加的theta功率在Fz和β的连贯性在T4-Fz，这表明，通过言语认知阶段的顺序手指敲击任务的进展是伴随着更窄的注意力和改善刺激和手指运动之间的映射。(C)2010 Elsevier B.

This study examined changes in EEG activity associated with motor performance during the verbal-cognitive stage of skill learning. Participants (n = 14) were required to practice a sequential finger tapping task. EEG activity was recorded both before and after short-term practice, during finger tapping and during two control conditions. EEG power (Fz, Cz, Pz, T3, T4) and coherence (T3-Fz,T4-Fz, Fz-Cz, Fz-Pz) were computed for the theta (4-8 Hz), slow alpha (8-10 Hz), fast alpha (10-12 Hz), slow beta (1220 Hz), and fast beta (20-28 Hz) bandwidths. Changes in motor performance were rapid during the very early stages of practice and then slowed in accord with the law of practice. These changes were accompanied by increases of theta power at Fz and beta coherence at T4-Fz, suggesting that progression through the verbal-cognitive stage of a sequential finger tapping task is accompanied by more narrowed attention and improved mapping between the stimuli and the finger movements.
