The purpose of this study was to investigate the factor, which influence the selection of internal pace on continuous forearm rotational task. Self-selected pace (Preferred pace, Slow pace, and Fast pace), resting EEG activity (first peak and frontal asymmetry), and mood states (liveliness, well-being, concentration, and sleepiness) were measured every 30 minutes from 9.30am to 5pm for 5 female subjects. Multiple regression analysis indicated that each pace has significant correlation to frontal EEG asymmetry of alpha-1 band (8-10Hz) and subjective well-being. Factor analysis indicated that three common temporal fluctuations were present, (1) first peak in alpha-band (8-13Hz), (2) subjective sleepiness and liveliness, (3) frontal EEG asymmetry, subjective well-being and concentration. Preferred Pace and Fast Pace were contained in the third component, and Slow Pace contained in the first and third component. These results suggest that left frontal activation and positive feeling may have an influence on the selection of internal pace.
