Dag,
Stimulated by your e-mail (using a new thread heading), attached are drafts of a slightly expanded version of the PCT model showing a number of influences on PCT control loop functions. As you can see, besides memory, other internal factors, mechanisms, and related descriptive concepts include hormones, drugs, expectations, overall affect such as mood, etc. The concepts indicated, although describing apparent influences at different logical levels, might help us think about the many internal factors that affect our perceptions and other control loop functions.
With Regards,
Richard Pfau

RM: … According to the PCT model, a perception, p, Â is always a function of environmental variables, x.1,x.2…x.n. That is. p = f(x.1,x.2…x.n). This is true whether p is a low level perception, like the angle of a limb, or a high level perception, like the honesty of a sales pitch.
Well, the PCT model does not account for memory. But when you enjoy your beloved Bach, memory is very much involved. You anticipate every note, don’t you.
So perceptions are functions of environvental variables, plus a huge amount retreived from stored memory.
The PCT model is limited in scope this way. That is OK.
Time to change thread heading ???
Best, Dag
