This document discusses the Expectancy Violations Theory (EVT) created by Judee Burgoon. EVT explains how people react when others violate their expectations, whether positively or negatively, during interpersonal interactions. An example is provided of a professor who positively violated a student's expectations by posing for pictures instead of getting upset. The document also discusses how EVT applies to everyday life through examples of teacher-student interactions and how understanding EVT allows one to better communicate with others by choosing when to violate or meet expectations.
