In Figure 5b the p-value is incorrect. The correct Figure 5 appears below as Figure 1.

Model fits to pupil responses. (a) An example of the correlations (r) for a single subject. The four conditions of interest were defined by the Accuracy x Difficulty interaction. Easy and Hard conditions for the model parameters were averaged based on the coherence levels presented to each subject. (b) Group-level correlation coefficients (r) for the comparison of the model parameters and pupil responses, for the pre-feedback (Pre; −0.5–0 s) and post-feedback (Post; 3–6 s) intervals. (c) An example of the correlations for a single subject using model parameters simulated with motion energy (error trials only). Pupil responses were averaged within six equal-sized bins based on the model parameter for each interval. Evidence strength is represented by mean motion energy within each bin (color bar). (d) Group-level correlation coefficients (r) for the comparison of the model parameters (using motion energy) and pupil responses, for the pre-feedback (Pre; −0.5–0 s) and post-feedback (Post; 3–6 s) intervals (error trials only). Error bars, standard error of the mean (N = 15). **p < 0.01, ***p < 0.001.

As such, this Article contains an error in the Results section under subheading ‘Belief State Model predicts pupil responses quantitatively better than Stimulus State Model’,

“For the post-feedback interval, there was a trend towards a stronger correlation for the Belief State Model than the Stimulus State Model (p = 0.074).”

should read

“For the post-feedback interval, there was no difference between the models (p = 0.326)”.
