It is still the major reference for PCT and discussion on CSGnet. CP spells out a suggestion for a working model of how the human brain and nervous system works. Our brain is a system that controls its own perceptions. This view suggests explanations for many previously mysterious aspects of how people interact with their world. Perceptual Control Theory has been accepted by independently thinking psychologists, scientists, engineers and others.
Few scientists recognize or understand the phenomenon of control.
It is not well understood in important aspects even by many control engineers. Yet the phenomenon of control, when it is recognized and understood, provides a powerful enhancement to scientific perspectives. It is essential to recognize that control exists and deserves an explanation in order for the discussions on CSGnet to make sense. These demos are available from the PCT Tutorials page.
