McCollough-type contingent aftereffects (CAEs) could be obtained using chromatic Mackay patterns comprized orthogonal orientations, such as concentric circles vs. radial lines. The results of the aftereffects and the supplementary studies of eye movements indicated that these CAEs were explained not in terms of spatial frequency or curvature but in terms of orientation. That is, the local orthogonality of two adapting stimuli on the retina was an important factor to produce them. The characteristics of the established CAEs, however, suggested that they were processed at a lower level of the central system. They occurred even when the structure of the test pattern was not recognized. The results were discussed in view of orientation detectors and their mutual lateral interactions.
