Visualizing behavior through HPCT -Reply

[Hans Blom, 960227]

In the current PCT model, if I think that John Doe has some
perception that he wishes to maintain, then I can predict his
behavior when I disturb or threaten to disturb his perception
(assuming that I am familiar with his behavior repertoire).

In the current PCT or HPCT model, I cannot predict what perceptions
John Doe's brain will "decide" that John needs to maintain.

This is the prediction that I am interested in.

I sympathize with your point of view. To me, Bill's proposed
hierarchy needs to be replaced by a "needs hierarchy", about which
biology can tell us something. Organisms control, above all, for the
"need" to transmit their genes to the next generation. Everything is
subordinate to this prime goal. That is what evolution theory is all
about. In order to achieve the prime goal, life must be maintained
for a prolonged period. So the subordinate goals of bodily survival
result as the next hierarchical level (see e.g. Maslow), the needs
for oxygen, food, water, integrity of the skin, homeostasis of body
temperature, etc. But just _how_ each individual realizes these goals
(_what_ to eat or drink, _how_ to acquire food and to keep warm and
safe) greatly depends on his/her 'personal culture' or behavioral
repertoire, as you note.

So it seems to me that the grand picture is in place, but also that
it is quite difficult to collect and predict the individual puzzle
