...This would be the case for color adaptation (Bompas & O’Regan, 2006), perception in binocular rivalry (Marx & Einhäuser, 2015), or the disambiguation of bistable stimuli (Haijiang, Saunders, Stone, & Backus, 2006)....

...This phenomenon of object constancy might be explained in terms of sensorimotor contingencies that the visual system would learn between eye movements and saccade-induced changes in the retinal inputs (Bompas & O’Regan, 2006; O’Regan & Noë, 2001)....

...Recently, Bompas and O’Regan (2006) provided experimental evidence for a similar type of learning but with colored patches on a monitor rather than spatial distortions caused by wedge prisms. The role of a sensorimotor mechanism in color perception, they argue, may have been first discovered by Kohler (1951), but he interpreted this effect as the result of adaptation to a contingency between color and eye position, rather than a movement of the eyes. Bompas and O’Regan (2006) had subjects judge the relative color of two spots (“greener” or “redder”), one coincident with a leftward saccade and one with a rightward saccade, both before and after a learning phase in which observers were introduced to a contingency between direction of eye movement and color....

...One important point about the study of Bompas and O’Regan (2006) has to do with the direction of the sensorimotor learning effect. The shift in PSE that they produced was in the same direction as typical adaptation to color that does not involve eye movements. Just as in chromatic adaptation, where being steadily exposed to a green field of light (for example) over time reduces the effective “greenness” of the light (Gibson & Radner, 1937; Helson & Michels, 1948; Jameson & Hurvich, 1972; Judd, 1940; many others), the effect detailed by Bompas and O’Regan was that subjects responded as if a spot looked the opposite of the hue that was paired with the eye movement in the learning phase. This complementary direction of adaptation has also been seen with blur (Webster, 1999), orientation (Greenlee, Magnussen, & Nordby, 1988), motion (Anstis, Verstraten, Frans, & Mather, 1998), and specific facial characteristics (Webster & MacLin, 1999), though not as part of a sensorimotor contingency. Following Held and Hein (1963), we refer to this direction of sensorimotor effect as “compensatory”....

A shift in color judgments was measured after the learning phase, providing evidence that observers altered their point of subjective equality (PSE) after being exposed to the contingency. In the learning phase, leftward eye movements were paired with red spots, rightward ones with green, and the observers later judged spots appearing on the left as relatively greener and spots appearing on the right as relatively redder than they had done in the prelearning control phase. In Experiment 1, we seek to replicate and extend the basic finding of Bompas and O’Regan (2006), introducing a contingency between eye movements and the appearance of red or green spots....

...The direction of the effect reported by Bompas and O’Regan (2006) makes this explanation seem unlikely: if two events are coincidental, then one event would signal both, not the opposite of the...

...Similarly, chromatic hues can be associated to presaccadic locations in the visual field, which in turn biases color perception (Bompas & O’Regan, 2006a; Bompas & O’Regan 2006b), and even the same identity can be associated to different objects viewed centrally and peripherally (Cox, Meier,…...
