Figure 6. Actual vs. expected proportional PSE-shift.
Actual vs. expected proportional PSE-shifts are plotted for the human (A) and monkey (B) data. Blue and red lines represent type-II regressions of the vestibular and visual data (blue and red circles), respectively. The regression lines were constrained to pass through the origin. Blue and red shaded regions represent 95% confidence bands of the regressions. If PSE shifts were to follow the RBA predictions, the regression for both cues would lie on the line y=x (dashed black line). Gray shading represents regions where adaptation was in the unexpected direction.
