William T. Powers (2009) We hear quite a lot about models such as weather models which can be used to predict what will happen in the next few days, or models of colliding galaxies which […]

William T. Powers (2011) In PCT, we say that organisms learn control, not behavior. But the meaning of that isn’t self-evident — isn’t controlling also behaving? The organization of a control system, in most cases, […]

William T. Powers (2010) The title of this paper is somewhat misleading, in that the Method of Levels (MOL) did not start out as an intentional synthesis of other therapeutic techniques. It was originally just […]

William T. Powers …small changes convert von Holst’s model into a true negative feedback control system. lf we assume with von Holst that a similar architecture holds at higher levels in the nervous system, we […]

A proposal that the the emergence of negative feedback control and the emergence of life are the same thing. A picture emerges in which the basic principle of control runs like a unifying thread from the first living molecules to modern complex organisms. […]

Notes on the notion that the brain plans our movements and issues commands to muscles, pre-computing the precise muscle movements for people or robots. […]

If you are going to reverse engineer and then simulate living organisms and how they move about, it is important to simulate all the physics correctly, such as the ray tracing included in the Little Man. Here is a paper that offers significant improvements regarding simulating the actions of muscles. […]

A short post to CSGnet with comments on LCS III […]

Bill Powers discusses each of these acronyms: Control Theory, Perceptual Control Theory, Reality Therapy, The Method of Levels, and The International Association for Applied Control Theory. […]

A short post to CSGnet on how we think about our senses, our experiences, and how we draw conclusions about the reality we live in (or whether we think we observe reality directly and merely need to report what we observe. […]

A short post to the Control System Group network (CSGnet) on the difference between cataloging behaviors and modeling systems that use behaviors to control perceptions. […]

This intro to PCT is slanted toward those coming into to this subject from the physical sciences. Bill Powers develops an argument that leads from conventional views of behavior to the new view that PCT gives us, emphasizing in the end the odd role that organisms, seen through the eyes of PCT, play in a world otherwise dominated by physical laws. The point will be to show that control theory provides us with the germ of a radically new understanding, a break with all traditional theories of behavior—and many new ones as well […]

Explaining emotion from a PCT perspective. […]

A discussion of the origin of PCT. […]

William T. Powers Control of perception has been reported at very basic levels of life.

Another hard-hitting comment on the state of our contemporary behavioral sciences. […]

A hard-hitting essay by the creator of PCT on what you see when you look at behavior through the eyes of a physical scientist. […]

A continuation of PCT in 11 Steps, this is an overview of how control systems may come into being, change, cause internal conflict, and ways to resolve internal conflict. […]

From Reorganization to Evolution and Back
The concept of reorganization as such is irrefutable, but how can it work? In this essay and final comments, Bill Powers touches on the source and evolution of his thinking over the years. […]
