Simplified schematic of motion stimuli.
The behavior of a single dot in timeframes of 500 ms is shown. The occluding bars are denoted by dashed lines, which were not visible during the actual experiments. Coherent motion (A): the dot moves in a straight line. Spatial decorrelation (B): dot moves in a straight line until an occluder, where it is randomly repositioned alongside the other end of the occluder. Temporal decorrelation (C): dot moves in a straight line and is randomly repositioned within the stimulus every 500 ms.
