Embodied Facial Emotion Processing in Autism and Social Anxiety1836between Corrugator activity with Confidence in emotion recognition between groups (BF range: 0.08 %u2013 0.15), apart from the comparison of angry expressions between the AS group and the NC group, for which the evidence was inconclusive (BF = 0.58). For Perceived emotional intensity as outcome, in contrast, robust evidence for a difference between the AS and NC group could be found across prior specifications for angry expressions (BF = 12.76 at a medium prior), and less robust evidence for a difference between the SA and NC group (i.e., BF > 3 only at a narrow prior) (see Figure 2). The Bayes factors for the slope comparison against zero for each group suggested that slope differences between groups mainly seemed to be driven by a robust positive relation between Corrugator activity and Perceived emotional intensity in the NC group, however only when specifying a narrow prior (BF = 4.94), and not medium (BF = 2.19) or wide (BF = 1.24) priors. Bayes factors for the group comparisons of all other expressions were very low, thus in favour of the null hypothesis (BF range: 0.05 %u2013 0.10).Figure 2. Group differences in the relation between baseline-corrected, z-scored corrugator activity during the viewing of negative and neutral facial expressions and their perceived emotional intensity (rescaled to an ordinal scale of 0-10) by expression category, as observed in the Bayesian analysis. Robust evidence for group differences is indicated by a bracket, including the corresponding Bayes Factor.
