The chapter discusses several theories of discourse and interaction, including speech act theory, coordinated management of meaning theory, communication accommodation theory, and expectancy violation theory.
Speech act theory examines how language is used to perform actions through five types of speech acts: assertives, directives, commissives, expressives, and declaratives. Coordinated management of meaning theory explores how meanings are created, coordinated, and managed through rules and patterns of interaction. Communication accommodation theory addresses how people modify their communication behavior, such as speech patterns, to match or diverge from others. Expectancy violation theory focuses on how expectations shape interactions and the effects of violating expectations.
