Time zero indicates the moment of the corresponding finger-key contact. (i.e., Little finger keypress for the peak vel. of little finger flexion and elbow supination, and thumb keypress for the peak vel. of thumb internal rotation and elbow pronation). Each number in parentheses indicates 1 SD across participants.
