- by @Evadeh EvaHi Arne, Great to learn that you’re interested in PCT, and welcome to this forum. The rights to B:CP (Behavior – the control of Perception) is with the Powers family. Denny Powers is currently publishing the original book. If you email me (president@iapct.org) I’ll share what contact info I have, so you could inquire yourself. […]
- by @arnesauer Arne SauerDear colleagues, I’ve recently joined IAPCT, and I have a question I haven’t been able to settle on my own. As far as I can tell, none of Bill Powers’ books — Behavior: The Control of Perception above all — has ever appeared in German, even though a Chinese translation exists. Is that correct, or […]

Basal ganglia output dynamically controls skilled forelimb kinematics in real time. bioRxiv 2026.03.09.710687; doi: 10.64898/2026.03.09.710687 https://www.biorxiv.org/content/10.64898/2026.03.09.710687v2.full Basal ganglia output dynamically controls skilled forelimb kinematics in real time – PMC “These findings demonstrate that SNr output does not merely gate movement initiation but continuously regulates the stability and kinematic evolution […]
- by @bnhpct Bruce E. NevinThe concept of stigmergy has currency in biology, computer science, and organizational design. When they talk about stigmergy, they’re talking about some forms of collective control. The OED says it’s from the French stigmergie, coined in 1959 by the French biologist Pierre-Paul Grassé to describe the decentralized, mound-building behavior of termites. There’s more in Wikipedia […]
- by @VyvHuddy Vyv HuddyFor anyone interested, I’ve uploaded the R code used for the simulations reported in Chapter 6, Learning Curves and Psychological Change Across Populations: The Implications of Reorganization, in Interdisciplinary Handbook of Perceptual Control Theory, Volume II: Living in the Loop to OSF. The repository contains scripts for: E. coli random-walk simulations based on the Marken […]
