The Science

Perceptual Control Theory is the first comprehensive scientific theory of behavior. It was originally proposed by William T. Powers in his seminal book, Behavior: The Control of Perception, which was published in 1973. Now available in paperback, the book explains how all living organisms function. The book is highly scientific and difficult to understand for the lay person. In a later book, Making Sense of Behavior: The Meaning of Control, Powers explains his theory in layman's terms. Both books can be purchased from New View Publications through its web site at newviewpublications.com.

The primary therapeutic application of Perceptual Control Theory is known as the Method of Levels. For the past several years, a government supported practice involving a half dozen psychotherapists in Scotland uses MOL exclusively with their patients. A study of this practice was published in 2007. Additionally, a number of private practitioners in the United States are experimenting with volunteers using MOL. A book about MOL, published by Living Control Systems Publishing, is available through newviewpublications.com.

The Control Systems Group is a non-profit organization devoted to research aimed at validating Perceptual Control Theory. For information pertaining to the theory go to perceptualcontroltheory.org.
