The Second Edition provides a full update of its highly successful predecessor and features new material on key issues such as political activism, economic polarization, minority stress, same-sex marriage laws, dehumanization, and mental health stigma, in addition to a timely update on how victims respond to discrimination, and additional coverage of gender and race. All chapters are written by eminent researchers who explore topics by presenting an overview of current research and, where appropriate, developing new theory, models, or scales. The volume is clearly structured, with a broad section on cognitive, affective, and neurological processes, and there is inclusion of studies of prejudice based on race, sex, age, sexual orientation, and weight. A concluding section explores the issues involved in reducing prejudice. The Handbook is an essential resource for students, instructors, and researchers in social and personality psychology, and an invaluable reference for academics and professionals in sociology, communication studies, gerontology, nursing, medicine, as well as government and policymakers and social service agencies.
