Supplementary Figure 9: Pupil size and dynamic learning rates.

From: Adults with autism overestimate the volatility of the sensory environment

Supplementary Figure 9

The analysis reported in the main text indicates a sustained positive relationship between pupil size and precision-weighted prediction errors (ɛ3) in the ASD participants (Figure 5b). The precision weight (on the prediction error) is proportional to the update of environmental volatility and is formally related to dynamic trial-wise learning rate (α3) This additional analysis indicates that the learning rates themselves (α2 and α3) do not have a significant influence on pupil dilation in either group. As for the results reported in the main text (see Online Methods) this regression analysis included, trial type (face, house), fixation compliance, mean RT and UE-E ground truth contrasts, as control regressors. Shaded regions represent standard error of the mean.
