Global scale, duty cycle, and speed have strong effects on the depth ordering of superimposed random dot moving surfaces, similar to those produced on superimposed drifting gratings. (A) Fraction of time that surface 1 is perceived as being behind surface 2 decreases as a function of its scale for three different duty cycles ratios. The fraction also decreases as a function of the duty cycle (duty cycle increases from top to bottom). The scale is measured in relation to the reference surface 2. (B) Fraction of time that surface 1 is perceived as being behind surface 2 as a function of its speed ratio v1/v2 (the speed of surface 2 was fixed at 5.4°/s).
