Interpersonal relations: Cooperation and competition.

Social relations between two persons require that consequences each receives depend at least in part on the responses of the other. Historically, research in several areas has focused on two contingencies, cooperation and competition, in which reinforcement is determined by the responses of both participants. A major research question in social psychology and applied behavior analysis has been: Which contingency is more effective with regard to the quantity or quality of some response? Although this question has not been addressed in the experimental analysis of behavior, this area provides a perspective and method to more fully investigate the relevant controlling variables. Among these are the frequency of opportunities to audit the performances of others, information (or lack of it) provided by social or nonsocial stimuli with regard to reinforcement and performance, degree of face-to-face interaction, types of reinforcement contingencies, and number of participants. A neglected dependent variable is cost effectiveness-amount of behavior maintained by a given reinforcer amount. The larger agenda for the experimental analysis of interpersonal relations includes a variety of forms of reinforcement interdependence that raise issues of basic and applied interest.
