If we understand our Self (the sense of who we are or even our personality) can shift from social situation to situation, we can then understand why our patients or our friends act in a certain way to a certain topic or time frame. In other words, the answers we must look for is not the obvious but is "hiding" behind the social background of the people we are trying to understand or help. 

What the behavioural science is trying to get us to do through Psychology and Sociology is to analyse human behaviours through the eyes of science. Instead of a "common sense" answer which will most likely yield a wrong answer, we are challenged to ask Why and to find out How to change the patients behaviour through solution that are custom-made for them.   Understanding their "sense of self" is part of the key of understand the prigins of their behaviour

We will move on to explore the main theory that we will be using throughout Term 2 when we look at how different social factors create pressure on individuals behaviour. This key theory is the Trans-Theoretical Theory of Behaviour Change.
