Appendix 1—figure 10. Accuracy of RT postdictions.

Left panel: The mean within-subject (across-trial) correlation between observed and postdicted RT data (y-axis) is plotted for each model (gray: MCD, blue: DDM1 and DDM2); error bars depict s.e.m. Right panel: Mean z-scored log-RT (y-axis) is shown as a function of |ΔVR⁰| (x-axis) and VCR⁰ (color code: blue = 0–50% lower quantile, green = 50–100% upper quantile); solid lines indicate empirical data (error bars represent s.e.m.), diamond-dashed lines represent DDM1 postdictions and star-dotted lines show DDM2 postdictions.
