Interaction theory has not been applied to interpersonal communication because the Western scientific model requires that variables be consciously apparent. A simple model of sending and receiving is not adequate to explain the complex nature of human communication, however. The dyadic pattern of interrelationship may be expanded to reflect the subtleties of interaction through the inclusion of the concepts of continuous feedback, covert forces and internal monologue, and the qualitative measures of "acting out," and "working through." Authority and power relationships may be explained in terms of mutually accepted dominance and submission roles and communication patterns. Working together productively implies the knowledge of the dynamic and often subconscious processes in human communication. (KS)
