“…reported that he "probably" saw I in just over 1% of the trials; he reported that he "definitely" saw it in an additional 0.6% of the trials. Most such trials occurred when I was strongly chromatic, consistent with the results of Yellott and Wandell (1976), who studied metacontrast as a function of the hue difference between mask and test. The metacontrast mask was extremely effective for Subject A.L.N., who never reported seeing the inducing field.…”

“…Second, the priming effect is inconsistent with the characteristics of metacontrast (Breitmeyer, 1984). Although metacontrast in dichoptic masking occurs with a target presented to only one eye (Yellott & Wandell, 1976; Howard & Rogers, 1995), the present suppressive effect arises only if both eyes simultaneously receive the rival stimuli (Experiment 1). Moreover, metacontrast is established with a mask following the target.…”

“…Contrary to the chromatic after‐effects by adaptation (McCollough, 1965; Skowbo et al., 1975; Meyer, 1977), the color‐specific effect in metacontrast occurs even if the target and mask are presented dichoptically (Yellott & Wandell, 1976). Therefore, it is inferred that the effects in metacontrast would be managed by processes at or beyond the site of convergence of the inputs from the two eyes (Yellott & Wandell, 1976). In contrast, the adaptation‐induced color after‐effects are probably due to processes occurring before binocular fusion (Howard & Rogers, 1995).…”

: In a situation where the two eyes separately receive two dissimilar images such as a blue square and a red square, the brain is forced to resolve competitive interpretations of the visual inputs. Earlier studies have indicated that adaptation to one of two rival images can control the following competitive perception. Consistent with those studies, the present experiments revealed that immediately after a brief presentation of a color (priming stimulation) to the two eyes, subjects dominantly perceived the other color out of the chromatic rivalry. This effect showed an interocular transfer even if indirect monocular priming was employed, but the filtering out of a primed color did not occur when an unprimed rival image was removed from the other eye. These facts suggest that binocular feature-detection processes in the human visual system might be responsible for the priming effect on rival images.

SUMMARYThe brightness of a brief flash of ligh'; is reduced by the sui4~able presentation of a second flash in an adjacent region of the visual field. This masking effect (metacontrast) can be induced dichoptically, that is with the test flash presented to one eye and the masking flash to the other. By a suitable choice of wavelengths and conditioning field, the test flash may be arranged to effectively stimulate only rod receptors and the masking flash only cone receptors. A dichoptic masking effect is still obtained. The rod and cone receptor mechanisms of the human visual system function independently in dark-adaptation ~md certain increment threshold measurements [8,16,19,29,22]. Interaction between the tw(, receptor systems has, however, been demonstrated in other increment thr~:~hold determinations [ 7,12], in the production of some chromatic effects [ 1~,:L7,23t, in the cancellation of mesopic flicker [11 ] and in a particular movement illusion [6]. F~r the visual masking effect known as metacontrast [ 1,9,18], where the brightness of a flash of light is reduced if it is followed a short time later by a second flash to an adjacent region of the retina, da~a showing both rod-cone independence [2land rod-cone interaction [5] have been obtaine~. These studies have used monoptic stimulation, that is, both test a,-,d n ~asking flashes presented to the same eye. The present work is concerned with rod-cone interlction when the met2contrast is produced by dichopt'.c stimulation, that in, the test flash presented to one eye and the masking flash to the other [see refs. 10,14 and 21]. Evidence that under such conditions the metacontras~ is not specific to a pa~icular class of receptor has already been reported [24].,The experiments reported here were carr:.ed out while the author~ were in the Department of Physics, Imperial College of Science and Technology, London, Great Britain.
