In-Group Ostracism Increases High-Fidelity Imitation in Early Childhood.

The Cyberball paradigm was used to examine the hypothesis that children use high-fidelity imitation as a reinclusion behavior in response to being ostracized by in-group members. Children (N = 176; 5- to 6-year-olds) were either included or excluded by in- or out-group members and then shown a video of an in-group or an out-group member enacting a social convention. Participants who were excluded by their in-group engaged in higher-fidelity imitation than those who were included by their in-group. Children who were included by an out-group and those who were excluded by an out-group showed no difference in imitative fidelity. Children ostracized by in-group members also displayed increased anxiety relative to children ostracized by out-group members. The data are consistent with the proposal that high-fidelity imitation functions as reinclusion behavior in the context of in-group ostracism.
