Ritual increases children's affiliation with in-group members

This study examined the impact of ritual participation on children's in-group affiliation (N = 71, 4-11-year-old children). A novel social group paradigm was used in an afterschool program to test the influence of a ritual versus a control task on a measure of affiliation with in-group versus out-group members. The data support the hypothesis that the experience of participating in a ritual increases in-group affiliation to a greater degree than group activity alone. The results provide insight into the early-developing preference for in-group members and are consistent with the proposal that rituals facilitate in-group cohesion. We propose that humans are psychologically prepared to engage in ritual as a means of in-group affiliation.
