The question asks to identify the scholar who first proposed a communication model focused on maintaining equilibrium in a social system.
Theodore M. Newcomb is the scholar credited with introducing this concept. His work, particularly the development of the A-B-X model, highlighted how communication facilitates the maintenance of balance and consistency within social relationships and systems.
Newcomb's A-B-X model illustrates how individuals (A and B) communicate about an object (X) to maintain agreement or orientation towards it. This shared orientation, facilitated by communication, helps reduce strain and maintain equilibrium within the social system formed by A, B, and their relationship to X.
While other scholars like Harold Lasswell (5 W's model), Melvin Defleur (Mass Communication model), and George Gerbner (Cultivation Theory) made significant contributions to communication studies, Newcomb's model specifically addressed the role of communication in achieving and sustaining social equilibrium.
Therefore, Theodore M. Newcomb's model was foundational in linking communication directly to the maintenance of equilibrium in social systems.
