More commonly known today as Choice Theory, Control Theory states that behavior is caused not by an outside stimulus, but by what a person wants most at any given time. This theory of motivation proposed contends that behavior is never caused by a response to an outside stimulus. Instead, the control theory states that behavior is inspired by what a person wants most at any given time. William Glasser, who developed the theory, contends that all behavior is intended to satisfy one of the following five internal needs:
1) To survive.
2) To belong and be loved by others.
3) To have power and importance.
4) To have freedom and independence.
5) To have fun.
This theory of motivation proposed contends that behavior is never caused by a response to an outside stimulus. Instead, the control theory states that behavior is inspired by what a person wants most at any given time: survival, love, power, freedom, or any other basic human need.
By understanding the drives for SURVIVAL, POWER, LOVE, BELONGING, FREEDOM, and FUN in people, we become more conscious of the need for our world to be a quality world of our choosing (retrieved May 02, 2005, from http://raider.muc.edu/~schnelpl/Control%20Theory%20-%20Overhead.html).
Thus, the Choice aspect of Choice Theory–that individuals have the power to change their lives for the better based on the choices they make.
The Ten Axioms of Choice Theory
1. The only person whose behavior we can control is our own.
2. All we can give another person is information.
3. All long-lasting psychological problems are relationship problems.
4. The problem relationship is always part of our present life.
5. What happened in the past has everything to do with what we are today, but we can only satisfy our basic needs right now and plan to continue satisfying them in the future.
6. We can only satisfy our needs by satisfying the pictures in our Quality World.
7. All we do is behave.
8. All behaviors are Total Behaviors and are made up of four components: acting, thinking, feeling and physiology. All Total Behaviors are chosen, but we only have direct control over the acting and thinking components.
9. We can only control our feeling and physiology indirectly through how we choose to act and think.
10. All Total Behavior is designated by verbs and named by the part that is the most recognizable.(retrieved May 02, 2005, from http://raider.muc.edu/~schnelpl/Control%20Theory%20-%20Overhead.html).
How this is done
A person can take greater responsibility for his actions and make the proper behavior choices by examining the following questions:
1) What do you want?
2) What are you doing to achieve what you want?
3) Is it working?
4) What are your plans or options?

This is interesting. Seems to be based in Mazlow’s famous pyramid.
