Sample data from one participant performing the sequence “2-3-1.” (A) sample plot of hand kinematics (B) definitions of timings. X-axis is left and right, tangential velocity is calculated off line with Matlab. RT (reaction time) or movement onset is defined as when tangential velocity >0.0035 m/s. FT (first action time) is when participant taps their first drum (drum 2 in this case). LT (last action time) is when they taps their last drum (drum 1).
