<P><EM>The European Review of Social Psychology</EM> is an e-first journal published under the auspices of the European Association of Social Psychology. Visit www.psypress.com/ersp for the journal's full Aims and Scope.</P>
<P>This volume contains reviews of research programs by leading researchers on central topics of social psychology such as attitudes, social projection, social power, coalition formation, inter-group conflict and strategies to reduce prejudice. To give only a few examples, chapters on attitude range from a social identity approach to attitude research (Smith ' Hogg) to a review of findings on the relationship between implicit and explicit measures of attitudes and stereotypes based on data from more than 2 million respondents (Nosek and colleagues). Chapters on intergroup conflict range from a review of research on the interindividual-intergroup discontinuity effect (Wildschut ' Insko) to presentations of research programs based on two new theoretical approaches, the revised common ingroup identity model (Dovidio and colleagues) and the ingroup projection model (Wenzel, Mummendey and colleagues). Research on the reduction of prejudice through direct and extended cross-group friendship is discussed by Turner, Hewstone and colleagues.</P>
