(a) Top view of the parallel-texture condition. (b) Top view of the convergent-texture condition. (c) Side view of a suspended test target at near and a test target on the floor at far (filled circles) and their relationship to the fixation target (open circle) in Experiment 1. During the experiment, only one test target, near or far, was shown in a trial. (d) Side view of the three-paired targets used in Experiment 2. In each pair, which was shown together during a trial, the near target was suspended and far target was located on the floor. Each paired targets had the same angular declination. (e) and (f) Perspective views of the parallel-texture and convergent-texture conditions, respectively. The dashed horizontal lines depict the horizon.
