We tested a hypothesis that responses to the Singelis' (1994) interdependent self scale would be enhanced after being exposed to an "exclusion game" -a social dilemma game with an option for excluding uncooperative members. Thirty-nine participants were assigned to one of two conditions. In the self-presentation condition, participants were told that their responses to the interdependence scale would be revealed to other participants after the experiment. In the control condition, participants were assured that their responses would be anonymous. The average interdependence score increased after experiencing the exclusion game in the self-presentation condition, and decreased in the control condition. These findings show that people come to present themselves to others as being more interdependent after being exposed to a social situation in which they face a threat of rejection from their peers.
