Chapter 6184As already indicated in the preliminary analysis, Confidence in emotion recognition was significantly reduced for all expressions in the AS group compared to the NC group (estimate range: -0.77 to -0.41, most p < .001 apart from neutral: .002). Moreover, the autism group rated specifically fearful and angry expressions as less intense compared to the NC group, estimate = -0.39, 95% CI[-0.67, -0.11], z = -3.13, p = 0.004 and estimate = -0.32, 95% CI[-0.60, -0.04], z = -2.60, p = 0.019, whereas no significant differences in Perceived emotional intensity ratings were observed between the SA and the NC group. Facial Muscle Activity and the Perception of Happy Facial ExpressionsSimilar to the models on the perception of negative facial expressions, we did not observe alterations in the link between activity in either facial muscle region and Confidence in emotion recognition of happy expressions as well as their Perceived emotional intensity (see Table S7 and S8 in the Supplemental Material for the model fits). Bayes factors of group comparisons ranged between 0.07 and 0.32, supporting the null hypothesis. There were only overall Group differences in the Confidence in emotion recognition, F(2,139) = 9.23, p <.001. Namely, the AS group showed to be less confident in accurately labelling happy expressions, %u03b2 = - 0.47, 95%CI [-0.73, -0.22], t(108.46) = -3.67, p < .001, compared to the NC group.Skin Conductance and the Perception of Facial ExpressionsThe model fits with Emotion recognition accuracy and Confidence in emotion recognition as outcomes did not show any significant effects associated with the predictor Skin conductance (see Table S9 and S10 in the Supplemental Material). Bayesian analysis confirmed that there was no robust support for alterations in the association between Skin conductance and Emotion recognition accuracy (BF range: 0.17 %u2013 0.73) or Confidence in emotion recognition (BF range: 0.09 %u2013 0.36) for all facial expressions, except for some anecdotal evidence in the AS-NC comparison for the accurate recognition of fearful expressions (BF = 1.83). As already reported in the previous models, Emotion recognition accuracy was found to be reduced for angry, fearful and sad expressions in the autism group compared to the neurotypical control group (see Table S9 in the Supplemental Material). Similarly, Confidence in emotion recognition was found to be reduced for all expressions, including the happy expression in this model, estimate = -0.30, 95%CI [-0.55,-0.05], z = -2.69, p = .014, in the AS group compared to the NC group (see Table S10 the Supplemental Material). Interestingly, when including all expressions in one model, Confidence
