Quadrant-based analyses: In Experiment 3, the converging and diverging patterns were presented in the same location within a quadrant in two different time intervals. Below flash is a schematic representations of a diverging stimulus in the first interval and a converging stimulus in the second interval. Participants' task is to indicate which interval contains a contour that is closer to the central fixation point (equal close in this example). In below flash, both motion-defined contours were presented in the upper right visual quadrant. In the other three conditions, both motion-defined contours were presented in either the upper left, the lower left or the lower right quadrant. The aim of this manipulation was to investigate whether the extent and direction of perceived spatial displacement varied with visual quadrant. The result of this experiment can be found in the next demonstration.
