Abstract
In the context of Covid-19 pandemic, barrier gestures such as regular hand washing, social distancing, and wearing face mask are highly recommended. Critically, interpersonal distances depend on the physical and emotional dimensions involved in social interaction, two factors that might be affected by the current Covid-19 context. In the present internet-based experimental study, we analyzed the preferred interpersonal distance of 461 participants, when facing a virtual character either wearing a face mask or displaying a neutral, happy or angry facial expression. The results showed that interpersonal distance is significantly reduced when the characters wear a face mask compared to other conditions. Importantly, it was also reduced in participants already infected with Covid-19, or living in a low-risk area. The present findings are of dramatic importance as they indicate that the general requirement to wear a mask in social contexts can have deleterious effects, interfering with social distancing recommendations.
