In artificial IS's, we can observe the computer program and all the processes that occur in the program, but, quite apart from that, we can also observe the concepts and response rules that the program created and stored. The computer program (corresponding to the fundamental physiological mechanisms) existed at the start of the computer run, but it learned the concepts and response rules as a result of experiences during the run. It seems, that in investigating the functions of the human mind, we should also clearly distinguish these two areas: fundamental physiological mechanisms from learned mental activity.
Fundamental Physiological Mechanisms
The fundamental mechanisms of the brain are those that are necessary so that all the functions of the brain, including storage in memory, can occur (These processes of the brain, we call the mind). The brain, through evolution, is so constructed that these functions do occur. They are present and required at the time of birth, so that the brain can start learning and directing the body. No concepts and response rules exist at birth, except the instincts that are like response rules (To be exact, the brain really starts to work prior to birth, when its growth has progressed sufficiently).
Using our terms, these mechanisms are:
The fundamental mechanisms of the brain vary little from person to person. Their speed reaches a peak (as all bodily functions do) in the early twenties and then start a slow decline. This includes the speed of formation of response rules and the amount of examples needed to form a new concept. On the other hand the total amount of response rules in memory increases during life. So a person usually is more intelligent after he has reached his early twenties.
There is a very good book on the fundamental mechanisms of the brain, "On intelligence" by Jeff Hawkins.
