Schematic illustration of one trial of the incentivised visual WM task. Participants were instructed to memorise three sequentially presented coloured bars, and adjust the probe bar’s orientation using the keyboard to replicate the orientation of the target bar with the corresponding colour. At the beginning of each trial, either a small (on the left) or a large (on the right) reward cue indicated the reward value of the current trial. ITI stands for intertrial interval.
