Example sequence of trials using the alternating ascending (asc)/descending (desc) stair-casing procedure from Experiment 2 (S=“same”/D=“different” response); for simplicity, we show only four runs per target, although the experiment included six per target. Note that degree labels were not present during the task, and the order of target presentation was counter-balanced across participants.
