1. GENERAL VIEW ON COMMUNICATION 1.1.-HISTORICAL BACKGROUND. According to Waltzlawick (1976), it is from 1945 that arise the scientific theories of communication. One of them was theories of information, purely technological basis and whose aim was to study the ideal conditions for the transmission of information and the limits and perturbations of the systems of communication in the abstract. On the other hand, spread the communication field in the abstract. On the other hand, spread the mass communication field, focused on the study of the characteristics and effects of the mass media and finally the study of communication as it occurs among humans.
The study of human communication covers three major areas: to) syntactic. ((b) semantics, c) pragmatic. The first is about the problems relating to transmission: encoding, channels, capacity, noise, redundancy and other aspects of the language. The second attack the problems relating to the meaning; all shared information presupposes a semantic Convention. The third focuses on how communication affects behavior.
1.2 CONCEPT OF COMMUNICATION. Watzlawick and others (1976) define the communication behavioral as the pragmatic aspect of human communication theory. Various units of communication, called them conduct and the message will be any communicational unit. A series of messages exchanged between people will receive the name of interaction. All behavior in a situation of interaction has a value of messages: words, silence, inaction, that influence on the others, thing which in turn respond to such messages and in fact equally communication. From the point of view of gestalt psychology, communication is based on observable behavior in the present, here and now. Awareness at present prevents the subject disrupt their communications with the internal system of if same or interpersonal system, noting three types of conduct or communication: driving (body language) symbolic (bodily events) and interpersonal (contact with other agencies).
