TL;DR: In this article, the authors tested the schema-based distrust interpretation of the tendency of intergroup relations to be more noncooperative than interindividual relations and found that the greater the within-group discussion of distrust for the other group, the less the number of cooperative choices.

TL;DR: A self-description task indicated that participants generate more aspects of their individual than collective self, and the individual self is motivationally primary.

TL;DR: This article found that when subjects were allowed to select a single, safe alternative, a significant, albeit descriptively smaller competitive effect remained, and that this effect is partly driven by group members' fear of being exploited by the outgroup.

TL;DR: This paper explored the role of communication on interindividual-intergroup discontinuity in the context of the PDG-Alt matrix and found that communication should produce a larger increase in the cooperation of individuals than of groups.

TL;DR: This article examined interindividual-intergroup discontinuity in the context of three different generalizations of the Prisoner's Dilemma Game (PDG) and found that interindividual intension is correlated with group discontinuity.
