Abstract

Facial mimicry has been considered an automatic, spontaneous process. However, recent research suggests that facial mimicry is dependent on the context of the social interaction, with increased mimicry occurring when the understanding of another’s emotional states is important. In this study, we examined the social context of facial mimicry of positive and negative facial expressions of emotion, and how mimicry relates to common variants in the serotonin transporter genotype 5-HTTLPR, which has been found to relate to proneness to negativity and to social sensitivity. Overall, the results of this study indicate that the negativity associated with a particular 5-HTTLPR genotype may be due to decreased processing of positive emotion rather than increased processing of negative emotion.
