In order to examine effectiveness of intergroup exclusion manipulation, participants are being asked following questions:
- How many times the ball was thrown between the players?
- Assuming the ball should be thrown to each player equally (50% of throws to players of each team) what percentage of throws did your national team receive in the Cyberball game?
Participants are being asked to report to what extent they felt ignored or excluded during the Cyberball game:
- I felt ignored.
- I felt excluded.
Participants are also being asked to assess to what extent they felt their group was ignored or excluded during the Cyberball game:
- I felt my group was ignored.
- I felt my group was excluded.
