Trial schematic from Experiment 1. After task instruction period (1000–2000 ms), ten dots were presented over 2000 ms, with a 50 ms blank after each dot, followed by the response period, which lasted until participant response. On location trials, participants reported the “average position” or “center” of the dots shown by clicking on a point on the screen. On size trials, participants reported the “average size” of the dots shown by adjusting a test dot. Dots varied in both position and size on all trials. Trial type was blocked.
