A Sequential Functional Model of Nonverbal Exchange

The sequential analysis of nonverbal exchange (NVE) begins with the identification of a set of antecedent factors that initiate preinteraction mediators. These mediators structure the perceived functions of an interaction and the levels of nonverbal involvement initiated by each interactant. The sequential-functional model proposes that functional bases of interaction are variable. The activation of different functions in an interaction is assumed to result in differing arousal, cognitive, and behavioral patterns in interactants. NVE is predicted to be more unstable as interactants' perceived functions and expectancies are more divergent. The model also proposes that one's nonverbal behavior may be a product of a general strategy or script and not simply a reactive product of the other person's preceding behavior.
