Effect of declarative and procedural presentations on the hierarchical motor-sequence-learning

Abstract

Motor-sequence-learning (MSL) is important for rehabilitation or sports, and the effective learning procedure according to the brain activity is considered to improve MSL. In this study, we in- vestigated the effect of declarative and procedural presentations in MSL of a 3-block pattern including 3-button-sequences in hierarchical manner. After an exchanging of the order of the blocks, the alpha- power of EEG at the parietal region (C3, Cz, C4) tend to increase during MSL in procedural presentation task. In addition, in declarative presentation task, the theta-power of EEG at the forehead (F3, Fz, F4) tended to increase and intra-block-time of button press increased significantly than in procedural presen- tation task. These results suggest that types of presentation of the motor-task influenced on the brain activity and the performance of MSL.
