Chapter 4108ResultsBehavioural ResultsAccuracy in Emotion RecognitionSocial anxiety traits. The first binomial GLMM on emotion recognition accuracy included emotion category, social anxiety traits, and their interaction as predictors. Results showed a significant main effect of emotion category, %u03c72(5) = 702.880, p < .001. Emotion recognition performance for happy, surprised, and neutral expressions was significantly better than average recognition performance, happy: OR = 10.834, z = 10.797, p < .001, surprise: OR = 3.027, z = 7.654, p < .001, neutral: OR = 2.337, z = 6.420, p < .001. In contrast, sad and fearful expressions were significantly worse recognized than average, OR = 0.232, z = -14.336, p < .001, and OR = 0.066, z = -23.445, p < .001 respectively. All the other effects or interactions were not significant. This suggests that recognition accuracy was predicted by the emotional content displayed in the video, independent of the level of social anxiety traits (see Fig. 2A). An overview of the model fit can be found in the Supplemental Material (see Table S1).Autistic traits. The second binomial GLMM on emotion recognition accuracy included emotion category, autistic traits, and their interaction as predictors. Results showed a significant effect of emotion category, %u03c72(5) = 666.374, p < .001, a significant effect of autistic traits, %u03c72(1) = 8.985, p = .003, and a significant interaction between autistic traits and emotion category, %u03c72(5) = 21.606, p = .001. The overall negative association between autistic traits and emotion recognition accuracy, OR = 0.763, z = -2.998, p = .003, was most pronounced for fearful expressions, OR = 0.637, z = -3.292, p = .001. Recognition of sad expressions was less negatively affected by autistic traits compared to the overall performance, OR = 1.322, z = 2.821, p = .005, and similarly recognition of surprised expressions, OR = 1.314, z = 2.067, p = .039 (for all other effects and more detailed information, see Fig. 2B and Table S2 in the Supplemental Material). Thus, the expected overall negative association between autistic traits and emotion recognition performance seems specifically pronounced for fearful facial expressions.
