Expectancy violations theory

Theory in communications

Expectancy violations theory (EVT) is a theory of communication that analyzes how individuals respond to unanticipated violations of social norms and expectations. The theory was proposed by Judee K. Burgoon in the late 1970s and continued through the 1980s and 1990s as "nonverbal expectancy violations theory", based on Burgoon's research studying proxemics. Burgoon's work initially analyzed individuals' allowances and expectations of personal distance and how responses to personal distance violations were influenced by the level of liking and relationship to the violators. The theory was later changed to its current name when other researchers began to focus on violations of social behavior expectations beyond nonverbal communication.
