Fig. 8. Results of a Bayesian model selection analysis.

The red blobs and table show the voxels and the number of voxels, respectively, that favor each model with an exceedance probability >0.95, indicating that the corresponding model provides a significantly better account for the BOLD activity in that region. Lee2014 refers to an arbitration control that takes into account only uncertainty as used by Lee et al.³⁰. Current model refers to the arbitration control model that was selected in the model comparison based on the behavioral data which incorporates both prediction uncertainty and task complexity. For an unbiased test, the coordinates of the ilPFC and the vmPFC ROIs were taken from ref. ³⁰.
