Fig. 5.

Task-related Power Spectral Density predictions from the quadratic models. The first row depicts the quadratic model’s mean predictions of mean PSD for the delta frequency band, the second row for the theta frequency band and the third row for the alpha frequency band. Predicted and empirical means are depicted across all sessions for each Feedback condition × Task combination. The shaded regions indicate 95% posterior credibility intervals. The marked dashed lines indicate the empirical means in each session, condition and task.
