Figure 6.
Example trial and probe stimuli from Experiment 3. (A) Trial timing was identical to Experiment 2, as was the presentation of a single grating probe at fixation. (B) Examples of the absolute LOW (shown on the left) and absolute HIGH (shown on the right) compound grating probes. In both examples, the 1.8 cycle/degree grating is shown tilted to the left (not drawn to scale). It is the relatively higher SF of the set in the absolute LOW grating and the relatively lower SF of the set in the absolute HIGH grating.
