Two experiments investigated the impact of group membership on non-conscious behavioral mimicry. Female participants viewed videotapes of female confederates who rubbed their faces whilst describing a picture. The extent to which the participant mimicked this face rubbing behavior was assessed from video footage taken using a hidden video-camera. Experiment 1 showed greater mimicry of a member of an in-group than of a member of an out-group. Experiment 2 showed both explicit and implicit liking of a target group to predict the extent of mimicry of a member of that group. There was a positive relationship between implicit liking and mimicry but a negative relationship between explicit liking and mimicry. Results are discussed in terms of processes underlying mimicry.
