Face-negotiation theory is a communication theory developed by Stella Ting-Toomey to explain how people deal with conflict situations. The theory proposes that culture, self-image, and social context influence a person's conflict style. It identifies five conflict styles - avoiding, obliging, compromising, dominating, and integrating. Studies have applied face-negotiation theory to analyze communication in contexts like healthcare and business marketing. The theory provides a framework for understanding how cultural values and concerns about one's public image shape approaches to conflict across different situations.
