Supplementary Materials

Experiment and model source code, videos showing human and model predictions for all sequences, and examples of model hypotheses are available at https://github.com/temills/ Below, we provide illustrations to show the experimental method in greater detail than provided in the main text. Figure S1 shows the exact instructions shown to participants. Figure S2 illustrates the experimental method with screenshots of a trial for the first three timepoints. A participant's task was to indicate where they thought the next point in a sequence would appear by clicking anywhere within the gray region, which surrounded the previous point's location.
