Trial to trial variability of peak velocity parameterized from chronologically ordered continuous head-movement cycles. (a) Group-averaged correlation coefficients of peak velocity between the current cycle and subsequent cycles (up to the twentieth) from six continuous gaze-stabilization exercises. The six exercises comprised three conditions (as shown in three columns) and two head-movement directions (pitch in the upper panel and yaw in the lower panel). Error bars represent the standard error of the mean (SEM). (b) The group-averaged intertrial correlation difference (ICD) for each exercise (x-axis). Error bars are standard error of the mean (SEM). ICDs represent the absolute difference of coefficients between each trial and the subsequent trial in the autocorrelation function.
