"The book covers a lot but its organization into three parts helps readers orient themselves around Marilyn Brewer’s lasting impact on the field. For social psychological and organizational behaviour scholars, there are sure to be chapters here of relevance and importance to their own work. ... Professor Marilyn B. Brewer is well deserving of all 423 pages. " - Katherine W. Phillips, Columbia Business School, USA, in Administrative Science Quarterly"Readers will have a clearer sense of the comprehensiveness of [Marilynn] Brewer’s work and a glimpse into the privilege of her mentorship. ... Social Cognition, Social Identity, and Intergroup Relations speaks to a wide variety of audiences. Though primarily geared toward social psychologists, it would also be of interest to developmental psychologists, industrial/organizational psychologists, and gender studies." - Stephanie Afful, Ph.D., Fontbonne University, USA in PsycCRITIQUES"This volume documents, in the chapters by several generations of leading social psychologists, the enduring conceptual and empirical impact that Marilynn Brewer’s scholarship, mentorship, and professional vision and leadership have had on the field. The book not only highlights her many significant contributions and chronicles her innovative insights, but also reveals how these contributions reflect an integrated, penetrating analysis of group life, social cognition, identity, and meaning. The book builds on Marilynn Brewer’s previous accomplishments to chart the course of social psychology well into the future." - John Dovidio, Yale University, USA"Marilynn Brewer is one of social psychology’s most distinguished scholars. Through her work on dual process models, optimal distinctiveness, social identity complexity, relational self, trust, dilemmas, and diversity she has transformed our understanding of intergroup relations and the role of social identity in intergroup behavior. This festschrift is a powerful testimony to Brewer’s impact, captured through the eyes of her students and collaborators – all leading figures in the field." - Michael A. Hogg, Claremont Graduate University, USA"A wonderful collection of intriguing and far reaching essays that honor one of social psychology’s most powerful and creative thinkers. That each chapter both makes an original contribution and addresses the legacy of Professor Brewer attests to the breadth and richness of her intellectual scope. Marilynn Brewer deserves a fitting Festschrift volume and this is it." - Dale T. Miller, Director of the Stanford Graduate School of Business' Center for Social Innovation, Stanford Graduate School of Business, USA
