Results from fitting the DDM to the data of van Ede <i>et al</i>.

<p><b>A</b>. The drift-diffusion model (DDM) assumes an accumulation process, until the evidence reaches a decision threshold. An increase of drift rate causes faster and more correct choices (red arrow). Non-decision time reflects the time other then the decision time (e.g. process sensory information and execute a motor response). <b>B</b>. Change in reaction time (RT) explained by drift rate (<i>v</i>) and non-decision time (<i>T_er</i>) for validly (blue) and invalidly (grey) cued trials compared to the baseline (uncued) RT. <b>C</b>. Time course for drift rate (<i>v</i>), showing the percentage increase from the baseline drift rate for validly (red) and invalidly (grey) cued trials. <b>D</b>. Time course for the percentage change in non-decision time (<i>T_er</i>) for validly (green) and invalidly (grey) cued trials compared to the baseline non-decision time.
