COMM 305 1st Edition Lecture 8 Outline of Last Lecture I. Uncertainty management Theory (cont.)II. Expectancy Violation TheoryOutline of Current Lecture I. Theories of Discourse and Interaction (cont.)II. Communication AccommodationCurrent Lecture- Question: How do we know what things mean?- Both theories were developed to explain nonverbal communication. First to explain how we know what nonverbal communication is. As of today, the theories have been broadened to include verbal communication.- Expectancy Violation Theoryo Nonverbal behavior Verbal refers to linguistics, the words we say, then nonverbal is everythingelse. Types of nonverbals- Paralanguage- the nonverbal cues that accompany speecho Involves volume or loudness, speed or rate of speech, pitchor tone, intonation 9 the rising and falling of the tone)- Body motion- gestures, movements of the body, facial expressions, eye behavior (blinking, gazing), and posture- Appearance- can involve those aspects of a person’s appearance that they have no control over (skin color, gender, physique) and those we can (clothes, hair). - Use of Space (proxemics)- perception and use of space. o Think of interpersonal space, how close a person is when talking to you.  But “how close” is too close is dependent on your culture, the intimacy with others.  And again, some situations are ok to have close proximity such as in a line, or on an elevator.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.o Ex: bathroom urinals (guys) Ideas to keep in mind- Nonverbal behaviors cannot be understood in isolation- When we try to read people like a book very well- Instead we see clusters of nonverbals.  Not all nonverbals are communication (ex: sitting in a chair and a man comes and sticks his fingers in your mouth. It seems weird, but not if it’s adentist. A dentist isn’t trying to communicate anything to you by putting his fingers in your mouth.) All nonverbals are context dependent. (Ex: universal greeting for saying hello is the “eyebrow flash” it’s like the sup head nod. But some cultures that can be sexual.)o Expectancies An expectation or guess about commutation behavior Particular nonverbals  How we think nonverbals will be used in an encounter Involve preconceived notions about who the communicators are, what the relationship it, and what the context is. Come from a variety of sources (culture, past experiences)They involve a range (EX: if your looking at someone in the eye, we know that appropriate eye gaze becomes uncomfortable at a certain range and the range is around 30 seconds, not exactly 30
