Figure A1.

Individual data for each subject for experimental conditions A and B. Error bars are standard deviation based on five trials for each gain and angle setting. A two-way ANOVA was used to reject the null hypothesis for dependence of motion on gain and dependence of motion on angle for all subjects. The null hypothesis for the interaction of gain and angle could be rejected for all subjects and conditions with the exception of subject 2, condition B (p = 0.3689) and subject 3, condition A (p = 0.3544).
