Subjects were exposed to a vertical chromatic grating alternating with horizontal chromatic grating of the identical frequency. They were then tested with a series of test gratings of varied spatial frequencies to examine whether the responses were effected by the spatial frequency of the adaptation pattern in relation to the test pattern. It was found that maximum response occurred when adaptation and test gratings had the same spatial frequency, the effect was asymmetric and finally that enhancements were found at octaves. Thus the experiment further demonstrated that neural elements specific to spatial frequency exist in the human visual system.
