General Discussion1977Table 1. Brief overview of the methodology and key findings in each chapterMethod Key findings2 Sample: N = 104, (1) zoo: n = 30; (2) festival: n = 22; (3) lab: n = 52Task: Dot-probe task with faces (anger, happiness, fear, sadness, neutral)Self-reported traits:Social anxiety: M = 37.12 [4-83]; Autism: M = 18.27 [2-38]Measures: Reaction times%u2022 Facial displays of anger, happiness, sadness and fear all elicited attentional biases%u2022 No robust evidence for a modulation of attentional biases by either social anxiety or autistic traits%u2022 Only in the Bayesian analysis, a decreased attentional bias towards happy expressions with higher autistic levels was found%u2022 Autistic trait levels and social anxiety trait levels showed a complex interplay in predicting attentional biases to anger expressions3 Sample: N = 71, labTasks: (1) Passive viewing and, (2) Labelling of static facial and static bodily expressions (anger, happiness, fear, sadness, neutral), static emotional cues (tears, blush, dilated pupils)Measures: Facial muscle activity (%u201cfrowns%u201d/%u201csmiles%u201d), skin conductance, cheek temperature, emotion recognition, confidence in recognition, perceived emotional intensity%u2022 Both facial and bodily expressions of different emotions (anger, happiness, sadness and fear) were reliably recognized, with a pronounced advantage for happy faces (versus bodies)%u2022 No evidence for robust physiological response patterns in response to distinct emotional expressions, but robust%u2026o facial mimicry of happy faces o early peak in skin conductance for angry faceso initial drop in cheek temperature for sad bodies%u2022 Facial expressions with tears strongly resonated in the observer, reflected by high perceived intensity ratings as well as a pronounced peak in skin conductance4 Sample: N = 57, labTasks: (1) Passive viewing and, (2) Labelling of spontaneous, dynamic facial expressions (anger, happiness, fear, sadness, surprise, neutral)Measures: Facial muscle activity (%u201cfrowns%u201d/%u201csmiles%u201d), emotion recognition, confidence in recognition, perceived emotional intensitySelf-reported traitsSocial anxiety: M =38.53 [7-73]; Autism: M = 16.47 [2-39]%u2022 Autistic and social anxiety traits showed distinct alterations in emotion perceptiono Higher autistic traits related to worse recognition of facial expressionso With higher autistic traits, mimicry was less predictive of emotion recognition o With higher social anxiety, confidence in emotion recognition was reduced, despite no actual differences in recognition performance
