Fig 5. Summary of inferred parameters of the four-parameter model for all 89 participants.

We show histograms of the median of the posterior distribution, for each participant. Solid red lines indicate the median of the group hyperparameter posterior estimate with dashed lines indicating 90% credibility intervals (CI). (A) Histogram of strategy preference parameter θ. (B) Histogram of precision parameter β (last bin containing values > 8). (C) Histogram of discount parameter γ. (D) Histogram of reward ratio parameter κ.
