Figure 2. Perceived body rotation without GVS.

Mean perceived rotation for the group (±2 s.e.m.) is shown for trials in which no GVS was applied. Each graph shows the difference between the start and final positions (Error). A, subjects returned to within a few degrees of the start position and this was not affected by head pitch. B, at speeds less than 5 deg s⁻¹ outward velocity did not affect the accuracy of returning to the start. At 10 deg s⁻¹ they stopped short of the start point.
