P values from multiway ANOVA of the GA, GV and latency during steps of acceleration to a velocity plateau. In contrast to sinusoidal rotations, GA, GV and latency had no significant dependence on left vs right eye, or (for a given axis) the sense of rotation or head orientation. GA is the ratio of eye and head acceleration about a common axis during the constant-acceleration part of the stimulus after the onset of head rotation. GV is the ratio of eye and head velocity during the plateau of the head velocity 200-400 ms after onset of head rotation. Bold P values denote a statistically significant difference.
