The aims of this study were to test if perceived interdependence could have a significant effect on cooperation, and if trust could mediate that effect. Eighty-two college students of both genders played a two-person dilemma game with a bogus European partner. The level of subjects’ perceived interdependence with the other European citizens was measured, as well as the level of trust they allowed to their European bogus partners. Results show that perceived interdependence has a significant effect on cooperation that is fully mediated by trust. Theoretical and practical implications of the results are discussed.
