Update: Perceptual Control Theory and the Evolution of Culture

This is the stock letter I'm sending to friends and anthropologists. If you haven't had a chance to view my powerpoint presentation, it includes the current ways you can access it.

I hope to see you in Cherry Hill next month!




Update: Perceptual Control Theory and the Evolution of Culture

(Note: This supersedes my previous communication on this subject.)


As you perhaps know, I have been working on developing a naturalistic underpinning for cultural anthropology for about forty years.* I think I've finally found a solution to the problem, and I'd very much appreciate your thoughtful evaluation of, and perhaps contribution to, my solution. This solution might even help to re-unify cultural anthropology.

My approach is based upon Perceptual Control Theory (PCT), developed by William T. Powers and presented in his seminal book, Behavior: The Control of Perception (1973).

Rather than attempting to present PCT in written form, I've developed a 45-minute narrated and animated PowerPoint presentation to explain PCT and demonstrate how it can enable a naturalistic cultural anthropology.

I invite -- nay, urge -- you to view the presentation and respond to it.

The program is available (free, of course) in five versions, all identical in content (and audio quality):

     1. The actual PowerPoint version, archived (with its various
        elements and a freestanding PowerPoint Viewer) by WinZip,
        can be downloaded by pointing your browser to


     Advantages of this version:
        a. The file is small (32 mb) and can be downloaded quickly.
        b. You can easily access individual slides for re-viewing.
        c. The visuals are of the best quality.

        a. Retrieving it and running it require certain basic computer
           skills (a readme file is enclosed).
        b. To ensure that the narration and animation are always
           properly synchronized, you need to have PowerPoint 2003/XP
           or later installed on your computer.

     2. The full-scale movie version (780 mb) can be downloaded from


        a. The downloaded file is ready to run.
        b. It runs very well in Windows Media Player and many other
           movie viewers including Quick Time Player on the Mac.

        a. The file is very large and so takes long to download.
        b. Visual quality is slightly reduced.
        c. It's not as easy to access individual slides.

     3. The compressed movie version (206 mb) is at


     The advantages and disadvantages are the same as for 2, except
     that the size is smaller and the visual quality is seriously

     4. The very compressed Windows-only version (61 mb) is at


     The advantages and disadvantages are the same as for 3; it's
     even smaller but you can't play it on a Mac.

     5. You can obtain the DVD version by replying to this email,
        or sending a message to tcloak@unm.edu, including your
        postal mailing address.

     This version is of the same quality as 2, and can be played
     on any DVD viewer such as your TV.

Again, please obtain the program and help me to make it better.

And please forward this email message to your friends and colleagues, especially your anthropologist friends and colleagues, either now or after you've viewed the presentation.
