Supplementary Figure 7

As an additional validation of the HGF model performance we simulated trial-wise RTs using the fitted perceptual and response model parameters from each of our 24 ASD and 25 NT participants. These simulations can recover the group differences in the main behavioural effect of expectation (compare to Figure 2a&b in the main manuscript). Statistical analysis of these model simulated RTs indicates a significant expectedness * group interaction (F(1,94)=4.44, P=0.014), and the simulated UE-E RT difference was significantly lower when simulated from the ASD parameters, relative to the NT parameters(t(47)=2.57, P=0.013). ASD, autism spectrum disorder. NT, neurotypical. UE, unexpected. N, non-predictive. E, expected. Data points represent the mean of 32 simulations for each individual participant, shaded regions and error bars show 95% confidence intervals and 1 standard deviation of the group mean, red lines indicate the group mean. Star indicates significance at P<0.05
