Parameter recovery results: Mean group parameter values (black dots) for each of the 729 parameter combinations, separated by simulated values. The horizontal color lines represent simulated parameter values, and the boxplots represent distributions of the mean estimated values separated by the simulated parameter values. bb = boundary baseline, bp = boundary power, eta_pos = learning rate for positive prediction errors (PEs), eta_neg = learning rate for negative PEs, m = drift rate scaling, Ter = nondecision time
