This book grew out of a graduate course in cognitive organization and change that the author taught during his tenure at the University of Illinois at Chicago Circle. Two primary objectives of the course are reflected in this book: first, to provide a general conceptual framework for critically and systematically analyzing research and theory on attitude and opinion change; second, to stimulate research on fundamental problems, related to these phenomena, that are made salient as a result of this analysis.  First published in 1974. Routledge is an imprint of Taylor & Francis, an informa company.
