Communication cycle
Argyle's theory of the communication cycle centres on six key 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 house.

2. Message coded. This would be us putting our desire of a house into whatever method we want to communicate with. This may be a language, pictures, writing, or any other method you can think of.

3. Message sent. Here we have communicated our desire for wanting a house.

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 straightforward, but, not everyone is as on the ball 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 new.

Tuckman’s theory of group formation.
In any health and social care setting, group work is used. This always seems to work and people communicate very well. Ever wondered why? Tuckman came up with a theory as to why this is, for he noticed that when a group is brought together for a certain outcome that a number of stages are completed. I will now explain these :

Forming:
The initial stage of team development during which individuals have not yet gelled together. Everybody is busy finding their place in the team, sizing each other up, and asking themselves why they are here! The first offers advice on starting a new team while the second will help you take over an existing team (perhaps a far more common situation).

Storming:
People begin to see themselves as part of a team. However at this stage they may challenge each other, and the team leader, about things as what the team is doing, and how things should be done. As the stage title suggests, conflict and confrontation may occur in this stage, as differences become obvious. This may result in some loss of focus on the task.

Norming:
This is the phase where team members start to come together, developing processes, making ground rules, deciding who does what, and how things will be done. This phase is known by a sense of "togetherness".

Performing:
This is the final stage where increased focus on both the task, and on team relationships, combines to provide working together well. Performance is delivered through people working effectively together. Characteristics of effective teamwork will help you and your team sustain that performance.
