This article explores interpersonal functions of emotional mimicry under the absence versus the presence of visual contact between the interacting partners. We review relevant literature and stress that previous studies on the role of emotional mimicry were focused on imitative responses to facial displays. We also show that the rules explaining why people mimic facial expressions may be inapplicable when visual signals are unavailable (e.g., people attending an online meeting have their cameras off). Overall, our review suggests that emotional mimicry (...) functionally adapts to whether the perceiver and the expresser can see each other. We, therefore, argue that blocking visual contact between them may provide insight into emotional mimicry's social functions, thereby clarifying its role in fostering affiliation and emotional understanding.
