The mean biases of PSEs of two-POTS and three-POTS configurations as a function of two frame conditions for the small, medium, and large disparity conditions. The blue triangle and orange circle show the results of the front- and equidistance-frame conditions, respectively. Error bars signify the 95% confidence interval. The blue cross, connected dotted line, indicates the geometrical prediction as in Fig. 1.
