Model parameters for the winning model ConfUnspec.
Blue solid lines indicate parameter means, green dashed lines parameter medians. (A) Histogram of the reward learning rate αr. (B) Histogram of the inverse decision noise parameter β. (C) Histogram of the confidence transfer parameter γ. (D) Histogram of confidence learning rate αc. (E) Scatter plot between reward learning rate αr and confidence transfer γ. The black line indicates a linear fit to the data; the correlation coefficient is based on a Pearson correlation.
