Focusing on political psychology at the individual level (genes, early childhood, personality, decision-making, emotions, values, ideology) and the collective (group identity, social justice, mass mobilization, political violence, prejudice reduction), this interdisciplinary volume covers models of the mass public and political elites and addresses both domestic issues and foreign policy. The volume provides an up-to-date, comprehensive, and expertly distilled account of cutting-edge research within both psychology and political science.
