Model comparisons. A, Comparison of choice frequencies and model predictions for targets, competitors, and decoys. B, Results of the first generalization test (i.e., generalizing from two-alternative to all three-alternative choice trials). Left and right panels show results for the training and test datasets, respectively. Within each panel, average BICs/deviances per model are shown on the left and evidence for the best model for each participant are shown on the right. Lower BICs/deviances indicate better fits. Dashed line indicates the fit of a baseline model that “guesses” each choice with equal probability. C, Results for the second generalization test (i.e., generalizing from trials with an N option to trials with a decoy option). HD, Hyperbolic discounting model; ED, exponential discounting model.
