The process of communication can be represented by the following graphic:
The sender (or source in the SMCR model) is the transmitter of the message. There are five factors which influence the sender in any communication he transmits:
Communication skills influence the effectiveness of your communication; therefore, a good understanding of verbal and non-verbal communication is the key.
Attitude can be defined as a generalized tendency to feel one way or another about something. Attitudes influence our communication in three ways.
Knowledge level has a bearing on our ability to communicate effectively about a subject. A businessperson might feel ill at ease trying to talk with a farmer about cattle, mealies, or fruit. The farmer would not feel qualified to talk about inner city housing, traffic congestion problems, or city community policing. However, they may both feel quite comfortable discussing politics.
The position of the sender and the receiver in their respective social systems also affects the nature of the communicative act. Each one of us occupy a position in one or more social systems, such as our family, work groups, church, community, or the organisations to which we belong. We perceive those with whom we communicate as occupying a similar, higher, or lower position in their respective social systems.
Our culture also influences our communication effectiveness. Communication is more effective between persons with similar cultural backgrounds. Culture is independent of social position in many cases.
The message is what the sender tries to transmit to his specified receivers. Every message has at least two major aspects: content and treatment.
The content of the message includes the assertions, arguments, appeals, and themes which the sender transmits to the receivers. The treatment of the message is the arrangement or ordering of the content by the sender. The selection of content and the treatment of the message depend upon our communication skills, attitudes, knowledge level, our position in social systems and our culture. The selection of content and the treatment of the message we use also depends upon our audience and their communication skills, knowledge, attitudes, social position, and culture. A doctor, for example, would select different content and treat the message differently when talking about the same subject to two different audiences, i.e. his fellow doctors and a group of community leaders.
It is the individual or group that receives the message from the sender. The receiver must take the content and add meaning to it. (See previous paragraph.)
