Rick Marken explains how the causal / IVDV / Linear model used within psychological research is flawed. He explains how experimental tasks are formed from closed loop systems, just like tracking task, when studied closely. This approach fits with a Perceptual Control Theory account. This recording was made at the PCT50 50th Anniversary of Perceptual Control Theory Conference at the University of Manchester, 24th July 2010.

What is efficient for survival is having behaviours that actually achieve survival goals that are important, and a simple S-R account has no reference to any goals and so the organism would have no control over whether its response to the stimulus served its goals for survival. Once a reference value for a control unit is set in memory it can be used automatically - no signals needed to higher order systems. So, there would be no difference in time delay the behaviour in PCT is truly on target.

Can you make a prediction using PTC that could not be made by any other theory and then confirm it with experiment?

9:55 So what you say sounds like this:

Top case:

IF [state of light]=[on] THEN [set([state of button] to [on])]

IF [state of light]=[off] THEN [set([state of button] to [off])]

Bottom case:

IF [state of light]=[on] AND [state of button]=[off] then [set([state of button] to [on])]

IF [state of light]=[off] AND [state of button]=[on] then [set([state of button] to [off])]

Well, PCT method requires more processing time therefore it is evolutionary inefficient for survival.

man, you really need to doo a better presentation! pct is facinating, but I guess I wouldn't get that from this video :D

nice try, though. keep up the good work!
