Answer:
Argyle's theory of the communication cycle centres on six core concepts, or, a cycle. The cycle is as follows:
1. An idea occurs. For example, let us say that our idea is wanting to buy a car.
2. Message coded. This would be us putting our desire of a car into whatever medium we wish to communicate with. This may be a language, pictures, writing, or any other medium you can think of.
3. Message sent. Here we have communicated our desire for wanting a car.
4. Message received. The person or perhaps target audience we wish to notify of our desire to have a car [perhaps a parental figure] has received our message.
5. Message decoded. They now must take what we have said and attempt to decode it. Now, "I want a car" is pretty straightfoward, but remember, not everyone is as transparant as this, and this is the step where communication breakdown may occur as they may decode our message incorrectly.
6. Message understood. Hopefully the last step was effective and they understand what you were trying to communicate. Now the cycle can begin anew.
Hope that was informative, I'm studying this at the moment; pretty interesting stuff! ~Alex D
