Fig. 4: Results of pupillometry analysis.

A Pupil dilation in response to the receipt of an outcome in blocks where that outcome is volatile, compared to blocks in which that outcome is stable. This plot is subdivided into pupil responses to rewards and losses. There was a significant interaction between group, condition (volatile vs. stable) and valence (win vs loss) from 342 ms to 4904 ms after outcome onset. The RA group showed reduced greater pupil dilation to wins in the stable condition (compared to both other groups), and greater pupil dilation to losses in the stable condition (compared to both other groups). The lines represent the mean, with the ribbon representing the standard error. B Results of pupillometry analysis, by condition and valence. Top left is the pupil response to loss outcomes when these are stable, top right win outcomes when these are stable, the bottom left is loss outcomes during blocks where losses are volatile, and the bottom right is win outcomes when they are volatile. The lines represent the mean, with the ribbon representing the standard error. C The overall volatile-stable pupil dilation response to rewards during the time of the significant group*valence effect was significantly correlated with behavioural learning rate difference in the RA group only. *marks significant cluster-mass statistic.
