Experiment 2. (A) Perceived matches following adaptation to blurred (red circles, α = −0.5), 1/f (green triangles, α = 0), or sharpened (blue squares, α = +0.5) noise images on the left, and 1/f noise images on the right, averaged for the two observers. (B) Mean shifts in perceived matches after adaptation to blurred images (red circles, α = −0.5) and sharpened images (blue squares, α = 0.5) expressed as the difference between observed and veridical matches. The dotted gray line denotes a veridical match in both panels. Error bars are ±1 SEM.
