PULFRICH EFFECT WITH MINIMAL DIFFERENTIAL ADAPTATION OF THE EYES.
Abstract
Both experienced and naive Ss measured the displacement of a Pulfrich target with a sensitive stereoptometer when only the image of the moving target was filtered. The usual monotonic function of filter density was observed; the calculated retinal latency differences were consistent with those in the literature. Asymmetries in the Pulfrich effect with respect to direction of motion and individual differences were noted. It is suggested that two processes are confounded in the usual Pulfrich situation--contrast of the Pulfrich target and retinal adaptation. (Author)
