Colors are different ranges of objective H, as shown in panel D. Errorbars are bootstrapped sem. (A–C) Probability of switching choices as a function of the LLR for a change in the correct answer. Data were restricted to trials following strong evidence (|LLR| > 4) to directly investigate the ‘strong belief’ regime of the model predictions. (D–F) Probability of switching sides in which a strong LLR (|LLR| > 4) for the original side was followed by a change-point and weak (|LLR| < 2) evidence for the opposite side. Significant differences by H in subject data are indicated by asterisks (Bonferroni corrected p < 0.05, χ2 test). (G–L) Block-by-block choice accuracy on change-point vs non-change-point trials when the evidence (magnitude of LLR, as indicated) was relatively weak (G–I) or strong (J–L). Points are individual blocks that included ≥5 trials with the indicated conditions.
