Color-contingent tilt aftereffect: spatial frequency specificity

The stimulus specificities of the color-contingent tilt aftereffect resemble those involved in the McCollough aftereffect, with the major exception that the magnitude of the former increases monotonically with the spatial frequency of matched inducing and test gratings; this monotonic increase is not found for the achromatic tilt aftereffect. Like the McCollough aftereffect, the color-contingent tilt aftereffect is tuned to the spatial frequency of the inducing gratings and can be induced on both oblique and main axes of the retina.
