Many explanations and conflicting data characterize search for understanding the Pulfrich effect. The conventional filter and the episcotister were each used to create the Pulfrich effect. Individual differences in observations by 9 field-dependent and 9 field-independent Ss were measured. Field-independent Ss see a longer minor diameter of the ellipse in the Pulfrich effect than field-dependent Ss. These data support a differential latency in perceptual response.
