Abstract:
The thesis examined subgroup-superordinate group relations, and in particular compared the Ingroup Projection Model (IPM: Mummendey & Wenzel, 1999) with the Common Ingroup Identity Model (CUM: Gaertner & Dovidio, 2000). The subgroups were British and German or English and Welsh. The superordinate groups were The EU and NATO (Studies 1 and 2) or The EU and Great Britain (Study 3). Alongside relative prototypicality (IPM), power differentials and the degree of ingroup identification and superordinate category identification, as well as social reality constraints were considered. Study 1 (quasi-experimental, British-German, N - 43) revealed that the lower-power group (the British) demonstrated higher evaluative ingroup bias than the higher-power group (the Germans), and bias was fully mediated by the degree of ingroup identification, and, against the backdrop of The EU, by relative power. Relative prototypicality did not predict ingroup bias. In Study 2 (experimental, British-German, N= 181), the Germans were higher in allocation-based ingroup bias, the British in evaluative ingroup bias. Here, relative prototypicality and relative power mediated allocation-based ingroup bias in the EU condition. In the German sample, high dual identification saw the highest levels of evaluative ingroup bias. Study 3 (experimental, English-Welsh, N= 184) additionally measured the perceived legitimacy of sub-group relations. The higher- power English sample scored higher on allocation-based ingroup bias, and the lower- power Welsh on evaluative ingroup bias. Correlations supported IPM, that is, higher relative prototypicality was associated with higher ingroup bias. However in contrast to the predictions of IPM, lower relative prototypicality in the Welsh sample mediated higher evaluative ingroup bias in the EU condition, as did higher ingroup identification. Furthermore, no effects of legitimacy were found. Finally, simple slope analysis demonstrated that, consistent with CUM, an esteemed superordinate category can promote intersubgroup harmony.
