Research on small groups played an important role in the early formulation of social psychology. By the 1970s, however, the field had lost the interest of most social psychologists. Theory and Research on Small Groups reintegrates that work back into the mainstream of social psychology. The more recent `issues-oriented' approach has not only resulted in many interesting findings-it has also applied basic social psychological theory in new ways and, moreover, led to new theoretical developments that deserve more attention. This volume, which features the work of esteemed researchers from around the world, is a bountiful resource worthy of notice by all social psychologists.
