The honest mirror: Morality as a moderator of spontaneous behavioral mimicry

Two studies examined whether morality‐related information has a greater impact than sociability‐ or competence‐related information upon the spontaneous mimicry of an interaction partner. Participants were video recorded during an interaction with a confederate previously presented as moral versus lacking morality, or sociable versus lacking sociability (Study 1), or competent versus lacking competence (Study 2). Two coders rated the extent to which participants imitated the gestures of the confederate, participants’ postural openness, and the general smoothness of the interaction. When the confederate lacked moral qualities, mimicry and postural openness were lower, and the interaction was less smooth than when the confederate was highly moral, unsociable, or incompetent. Moreover, our findings showed that global impression is the key mediating mechanism driving such an effect. Indeed, knowing that another person behaved immorally resulted in a negative impression, which in turn hindered behavioral mimicry.
