“…The second characteristic of contingent aftereffects, which supports an ECD hypothesis, is that they do not transfer interocularly at the first test when the nonadapted eye is occluded or exposed to homogenous achromatic illumination during adaptation (McCollough, 1965;Skowbo et al, 1975), but do transfer to the nonadapted eye once they have been elicited in the adapted eye (e.g., Byth et al, 1992;Kaufman, May, & Kunen, 1981;Logue & Byth, 1993;Shute, 1979). This suggests that the formation and storage of the spurious pattern-color association may occur at the monocular level, but that the ECD, once triggered, operates at both monocular and binocular levels.…”
