Results of Experiment 9, in which the Poggendorff figure was presented dichoptically to give a stereo effect. The traversal was given a disparity to make it appear either behind or in front of the horizontal traversals. In the control (mono) condition the observer used one eye only. The top panel shows the means and 95% confidence limits. The bottom panel shows the individual data with each individuals error in the dichoptic condition (vertical axis) plotted as a function of the error of the same individual in the monocular condition (horizontal axis). Squares show errors in the behind-dichoptic condition and circles in the front-dichoptic condition. The diagonal line shows the locus of points expected if the dichoptic and monocular errors are equal; most points lie under this line, indicating a smaller dichoptic error.
