This text presents the most important and influential social psychological theories and research programs in contemporary sociology. Original chapters by the scholars who initiated and developed these theoretical perspectives provide full descriptions of each theory, its background, development, and future. The first four chapters cover general approaches, organized around fundamental principles and issues—symbolic interaction, social exchange, distributive justice, and rational choice. The following chapters focus on specific research programs and theories, examining identity, affect, comparison processes, power and dependence, social exchange, status construction, and legitimacy. A concluding chapter provides an analysis of and commentary on the state of the theoretical programs in sociological social psychology. Contributors: Peter J.
