The long-awaited second edition of Communication and Group Decision Making advances a unique perspective on group decisionmaking, complementing approaches taken in management, psychology, and sociology. Group communication processes are extremely important, yet they have proven to be elusive and difficult to understand, and the type of theory necessary to make sense of the processes differs from those commonly found in the social sciences. This exceptional book gathers together and discusses a number of strong theoretical frameworks that have developed over the past 15 years. Providing important empirical evidence, the authors take stock of recent developments in group communication research. The essays are distinctive, both in their explicit focus on communication processes and in their location in a unique intellectual tradition.
