Examples of dot motion stimuli with the algorithm. In the task, a proportion of dots move along the 90°–270° axis coherently and participants judge the direction of dot movement along this axis as either left-motion or right-motion (shown in the orange arrows). Distractor dots move in straight lines but at different axes (shown in grey arrows). Note that the orange and grey arrows appear here only for illustrative purposes; they were never present for any participants in any experiment. Panel A shows the algorithm’s recommendation (left green arrow) above the stimulus. In Experiment 1a and 1b the recommendation appeared above the stimulus automatically. In Experiments 2 and 3 the algorithm appeared on screen as a green box (Panel C) unless the participant made a request for a recommendation. If requested, the algorithm loaded the recommendation during a one-second delay displaying a “loading circle” that revolved around the box (Panel B). All motion in the stimulus stopped during this loading time and then resumed once the recommendation was revealed (as in Panel A)
