About Perceptual Control Theory
comments by Bill Powers
William T. (Bill) Powers originated PCT fifty years ago and has
spent a lifetime refining and teaching these ideas so people can
benefit from a correct understanding of how behavior works.

PCT Tutorials and Simulations
Tutorials, demos and simulations by Bill Powers you can run
on your Windows computer. The programs available here were reviewed
for functionality in 2004. Documentation was formatted for easy
reading and made as complete as possible. In the spring of 2004,
Bill Powers created Windows versions of the original DOS programs
and added new Windows programs. TrackAnalyze was updated with
version 5 in January, 2006.
NOTE: Bill Powers’s work Living Control Systems III : The Fact of Control (2008) with updated Windows programs is highly recommended. These programs and the book explaining them provide an excellent introduction to PCT.
DOS demos compiled by Dag Forssell in 1994-5 and distributed
on diskettes at that time are still available for download at
some PCT-related web sites. These are no longer recommended.
They have been superseded by the updated selection offered here.
For on-line demonstrations you can run using your browser,
