| Common projects like joint grant applications require that (members of) different groups work together, share information and expertise, and combine effort. In reality, however, these kinds of intergroup situations often amount in competition and conflict, rather than cooperation. Research so far has primarily focused on ways of reducing negative intergroup behaviour such as competition or discrimination, rather than on exploring ways to promote positive behaviour. Positive intergroup behaviour is manifested in such acts as helping outgroup members, sharing information with the outgroup, and exerting effort for the production of a common good that is to the benefit of the outgroup. The aim of this project is to investigate determinants of positive intergroup behaviour with respect to intergroup helping, effort and performance on behalf of the outgroup, and the sharing of information between groups. A distinction is made between prosocial and strategic motives. A prosocial motivation exists when positive intergroup behaviour is displayed because one believes that it is for the benefit of both groups. A strategic motivation exists when positive behaviour is displayed to assert group dominance. In several laboratory experiments and two field studies, determinants of both types of motivation are investigated, as well as moderating and mediating constructs, and the consequences in both behavioural and psychological terms. |
