Self-Expansion and Knowledge Sharing in Cross-Group Interactions

This research considers the role of self-expansion motivation and knowledge sharing orientation on the effects of cross-ethnic interactions. Study 1, a correlational study, showed that a higher level of self-expansion motivation prior to an actual cross-group interaction was associated with higher levels of the more specific desire to acquire knowledge from a cross-group partner, which in turn was associated with more positive cross-group interaction experiences, which were associated with higher levels of reported self-change as well as more support for multiculturalism and support for action for intergroup equality. Study 2, using an imagined contact scenario, partially replicated these findings, showing that a high knowledge-sharing orientation (knowledge acquisition and knowledge provision orientation) during an imagined cross-group interaction was associated with a more positive imaged cross-group experience and this was associated with more reported self-change, and more positive intergroup feelings and a greater interest in future contact with the target outgroup.
