contingent aftereffect

an altered visual perception in which one stimulus dimension (e.g., color) depends on a separate stimulus dimension (e.g., orientation). The McCollough effect is an example in which repeated serial exposure to horizontal red bars followed by vertical green bars induces an aftereffect of horizontal white bars appearing green and vertical white bars appearing red. The color of the aftereffect is contingent on the orientation of the test stimulus.
