Psychophysical studies on 3-D motion perception have shown that perceived trajectory angles of a small target traveling in depth are systematically biased. Here predictions from Bayesian models are investigated that extend existing models of motion-first and stereo-first processing. These statistical models are based on stochastic representations of monocular velocity and binocular disparity input in a binocular viewing geometry. The assumption of noise in these inputs together with a plausible prior for 3-D motion leads to testable predictions of perceived trajectory angle and velocity. Results from two experiments are reported suggesting that disparity rather than motion processing introduces perceptual bias.
