Although comprising diverse specialized topics of inquiry, social psychology maintains at its core the investigation of how an individual's thoughts, feelings, and actions are influenced by other people. It is fitting, therefore, that this inaugural volume in a series on social psychological processes and social issues features this central process of social influence as its main theme. Throughout its nearly tOO-year history as a discipline, social psychology has been both a basic and an applied science, although the relative emphasis accorded to these two interrelated functions has varied over time. For about the past 20 years, the "applied side" of social psychology has received increased attention. As reflected in the chapters of this book, the applied orientation has resulted in an expanded range of topics, subject populations, settings, and research methods em ployed by social psychologists. What has remained constant, though, is the guid ance provided by a body of theory, data, and principles about social psychological processes that are regarded as fundamental. It is assumed that these processes are "basic" in the sense of being relevant to many specific phenomena and practical problems: At the same time, it is expected that attempted applications to different topics will not only reveal the generalizability of these fundamental processes but will also suggest modifications in our understanding of them. In the present case, this book is intended to help identify possible solutions to social problems through applying knowledge about social influence processes and to advance general knowledge about the processes themselves. Aside from testing and expanding the limits of basic psychological processes as they apply to current social problems, another aspect of applied social psychol ogy entails the design and evaluation of interventions intended to ameliorate or even prevent such problems. Accordingly, another theme and purpose of this book is to demonstrate how social change strategies derived from theories and basic research on social influence may be effective in retarding the growth of social problems at some stage in their development. At least to the extent that problems xi
