extended contact (Wright et al., 1997)
based on Robbers Cave experiments: one person from each different group worked together and then discussed their experience with other ingroup members
- intergroup bias was significantly higher in the intergroup competition stage
based on minimal group paradigm: watched on group member working with a member of the other group - three conditions: hostile, neutral, friend
- mean rating of conditions similar for ingroup
- mean rating for hostile lowest, and friend highest in outgroup
