Three Views of Human Communication:

These views, or models, of human communication will be considered from a historical perspective, and then applied from a paradigmatic perspective. For our purposes here, we'll define a paradigm as a person's mental map of reality (closely related to the concept of a world view).

Berlo conceptualized a linear model which included the most basic elements of human communication.  S = Sender, the person in the exchange who initiates the message sending. M = Message, that which the sender wishes to give to other participant.  C = Channel, the method through which the sender encodes their message.  R = Receiver, the person at the other end of the exchange.

As you can tell from our discussions of communication, this model lacks the characteristics of the transactional models.  Because of that is less fluid, more static, one-way in orientation, and brings with it some false assumptions about how people communicate in real life.
