Formality in rhetorical delivery can be defined as a complex variable that represents the speaker's efforts to invoke sociocultural rules of audience control through the nonverbal components of the delivery. This document describes some of the aspects of formality, outlines its significance in rhetorical contexts, and evaluates the concept in terms of current conceptions of behavior and motivation. The model of formality contains these factors: physical distance from the audience, use of artificial forms of enhancing distance, attire, posture, gesture, movement, and certain elements of vocal behavior. Since rhetoric is concerned with effective communication and the factors over which a speaker exercises control, this model of formality can be useful in that it offers a coherent set of cues to elicit appropriate audience role behavior.
