Effectiveness of crowding in the first experiment. (A) In the first experiment, during crowded adaptation, subjects were instructed to report the direction of motion in the adapting Gabor (top, circled Gabor in Figure 2). Response accuracy is plotted as a function of adapting Gabor contrast. All three subjects were at chance in all conditions. (B) Response accuracy when there was no crowding (only the adapting Gabors were present). All subjects responded with more than 85% accuracy.
