Dopamine, Affordance and Active Inference
Figure 7
This figure shows the results of simulations under progressively reduced levels of precision (dopamine) as indicated by the equalities in the lower row.
The display format of these simulated responses is the same as used in the left panels of Figure 5 (conditional predictions and prediction error; hidden contextual causes at the second level and motor trajectories). The left column presents the conditional responses under normal levels of dopamine (as in Figure 5), while the middle and right columns show the equivalent responses for intermediate and low levels of dopamine. As noted in the main text, the main features of these simulations are reciprocal changes in the amplitude of prediction errors at the first and second levels that are associated with a progressive failure set switching (i.e., a failure to recognise that the order of stimulus presentation no longer conforms to sequential expectations).
