In this volume, leading researchers review contemporary theory and research on the ways people influence each other. Three sections examine processes and theory in social influence research, the role of cognitive processes and strategies in social influence phenomena, and the operation of social influence mechanisms in group settings. "This Sydney Symposium volume, the third in a series, showcases the best research done by a collection of stellar scholars in social influence. Collectively, they offer an integration and re-conceptualization of social influence phenomena, and help readers appreciate how these phenomena permeate myriad aspects of social thinking and social behavior." - Elizabeth Loftus, University of Washington
