Research suggests that social anxiety and autistic traits have distinct effects on facial mimicry and metacognitive judgments in emotion recognition. However, the relationship between facial mimicry and emotion recognition is unclear, with some studies indicating that restricting facial mimicry does not impair emotion recognition, while others explore the role of facial mimicry in predicting preferences and emotional contagion. The findings also touch on individual differences in emotion recognition, including the impact of idiosyncratic biases and interoception on facial emotion perception.
