4. Although the meanings of most violations can be determined from context, some
nonverbal expectancy violations are equivocal.
5. For equivocal violations, one must refer to the communicator reward valence.
E. Communicator reward valence.
1. The communicator reward valence is the sum of the positive and negative
2. Puzzling violations force victims to search the social context for clues to their
meaning and that’s when communication reward valence comes into play.
4. Communicator reward valence may loom large when it’s especially strong either

prevalence of reciprocity that has been found in interpersonal interactions.”
B. So she has reassessed EVT’s single-sided view of unexpected communication and
now favors a dyadic model of adaptation.
1. Interactional adaptation theory is an extension and expansion of EVT
2. Interactional position encompasses three factors:
a. Requirements—outcomes we all need to fulfill our basic needs to survive, be

expectations.
VI. Critique: A well-regarded work in progress.
