Figure 2. — Example psychometric functions for one representative subject for the four different experiments. Conditions colour-coded (see legend). (a) Traditional MAE. (b) PMAE with a 500 ms stationary test stimulus. (c) PMAE with a 500 ms test stimulus drifting at a velocity that annuls the MAE. (d) PMAE with a 50 ms stationary test stimulus. Closed circles show the results for adaptation for leftward motion in the lower stimulus and open circles adaptation in the opposite direction (red, full; green, retinotopic; blue, spatiotopic and grey, unmatched).
