Posterior estimates of model-based analyses. (a) Hierarchical softmax model. Expected rewards and uncertainties were regressed onto choice probability (Eqs. 1–2). The top row shows the value-directed component (\(\alpha \)), the middle row shows the uncertainty bonus (\(\beta \)), and the bottom row shows stickiness (\(\gamma \)). (b) Hierarchical RT model. The influence of relative reward (top), relative uncertainty (middle), and total uncertainty (bottom) on RTs. (c) LBA drift regression. Relative reward (top), relative uncertainty (middle), and total uncertainty (bottom) were used to predict the drift rate of an LBA. In all plots, the vertical dashed line indicates an effect of 0, while the black dot indicates the mean effect and confidence intervals show the 66% (thick) and 95% (thin) highest density interval.
