experimental results. Upper panel depicts both groups mean vestibular cognitive gain for chair rotations of ± 10°, ± 20° and ± 30°. The error bars represent ± 95% confidence interval. Lower panel presents both group means (black square = mean, boxes = standard error and, error bars = 1.96 × standard error) for the saccade accuracy in absence of chair rotation. Data for the ± 15° targets were pooled as no significant effect of direction was observed.
