Differences in SHV for CW and CCW rotations of the rod by the subject (ΔSHV). Overall average (± 1 StdDev) from trials with CW rod rotations were subtracted from trials with CCW rotations and plotted against head-roll angle. Positive values of ΔSHV reflect CCW shifts of trials with CW rod rotations relative to deviations of trials with CCW rotations.
