The stimulus used in the first experiment. (A) An array of 25 second-order Gabor patches was presented during adaptation. Subjects fixated on the bull’s-eye to the right of the Gabors throughout each session. The motion of each crowder Gabor was randomly determined in the initial and top–up adaptation periods, whereas the motion of the adapting Gabors (circled) remained fixed throughout an experimental session. (B) The test period consisted of Gabors containing orthogonal drift-balanced motion. These Gabors were superimposed on the location of the adapting Gabors (circled). (C) After adapting to the stimuli, test Gabors appear to be shifted in the direction opposite that of the prior motion adaptation. The circles were not visible in the actual display. (D) The procedure in each session.
