Perceptual Control Theory
More on PCT

People as Living Things: The Psychology of Perceptual Control
Philip J. Runkel  

“This comprehensive text is a superb overview of Perceptual Control Theory (PCT) and its practical applications for individuals, groups, schools, and organizations of all kinds. Runkel's style is personal, immediate, and often humorous. The book is written for the layperson and professionals interested in obtaining a deeper understanding of PCT and its meaning for people and society.

This book is the result of 18 years of immersion in Perceptual Control Theory, a new conception of human functioning. In these pages, Runkel introduces the theory and shows its implications for numerous aspects of human experience, thereby illustrating its significance and challenging crucial contemporary notions of how humans and human relationships can work.”

"This is a book that can show a willing psychologist how to do a new kind of research. The theme that runs through all these papers is modeling, the ultimate way of finding out what a theory really means.

Richard Marken is a skilled modeler.... But he has a talent that goes beyond putting ideas into the form of working simulations, a talent that can be admired but is hard to imitate. He finds the essence of a problem and an elegantly simple way to cast it in the form of a demonstration or an experiment."
