Example stimuli and results of experiment I. (A) Example static noise stimuli shown to left and right eyes, tinted blue and red to aid identification. The surrounding binocular ring and Voronoi texture aided fusion. (B) Results averaged across 4 observers and expressed as left predominance—the proportion of time the left image was reported as seen—as a function of α for the left eye. The terms “left” and “right” are used for convenience only, as in the experiment these were counterbalanced. Note that data points where both images had the same exponent sit near the horizontal dotted midline, indicating that they were equally dominant.
