Jessica L. Lakin, Tanya L. Chartrand: Need for inclusion with in-groups, nonverbal behaviour, reaction to exclusion, nonconscious mimicry

"Exclusion from social groups has negative emotional, psychological, and behavioral consequences. Yet it also seems important to explore the potential positive consequences; perhaps after exclusion, individuals engage in behaviors that help them affiliate with new people or re-establish themselves in the excluding group. The research described here demonstrates an affiliative behavior that occurs after exclusion – nonconscious behavioral mimicry."
