Stimuli, trial procedure, and predictions for Experiment 1. Note: A The chart shows the elements of the scrolling task of Experiment 1. Of the six possible starting position only one was displayed on each individual trial. Not the entire number line was visible at trial onset. B The panel shows the sequence of events in a trial. If the target number was centered between the target squares in step 5, the trial ended. Otherwise, participants could re-click the number line (step 3). C The chart shows the predicted results if participants minimize overall movement distance.
