The introduction outlines variables that affect the course of conflict, the functions of conflict, a typology of conflict, and destructive and constructive conflicts. Additional papers characterize the major differences between cooperative and competitive processes as revealed in theoretical and experimental work and conflict at the intrapersonal, interpersonal, and intergroup levels. Further papers present the results of experimental studies of trust and suspicion, the effects of threat and communication on interpersonal bargaining, structural and attitudinal factors in bargaining, and strategies of inducing cooperation. The concluding essay describes the typical characteristics of destructive and constructive conflicts, the factors that determine which mode of conflict resolution will be dominant, the regulation of conflict, the role of third parties in this process, and some of the special issues relating to conflict between the weak and the strong.
