These introductions and readings provide a comprehensive range of information for the study of Perceptual Control Theory—papers, books, book reviews, resources on-line, demos and tutorial programs for your computer. Perceptual Control Theory, PCT, results from one man's curiosity, expertise, creativity and determination. The articles, books, and tutorial programs introduced in this volume would not have been written, certainly not this way, if it were not for William T. (Bill) Powers's seminal insight and tireless efforts across more that sixty years. The PCT explanation for what behavior is, how it works and what it accomplishes is well documented. It lays a foundation for a new natural science and can handle behavioral phenomena within a single testable concept of how living systems work. You can demonstrate it yourself with functioning computer simulations. Whether you are interested in improving education, resolving chronic psychological stress, understanding what is going on with an inconsolable baby, understanding the basis for our universal sense of justice, getting a different take on what emotions are, resolving conflict in general, becoming a better parent, manager, sales person, friend or lover, you will find fascinating insight when you review these readings and study this new explanatory concept with care.
