Hi Gerry:
Its been 25 years since I got a BA degree in Pysch, or even done any
reading in the field, but I believe the basics haven't changed that
much in the physiology of learning theorey. One of the distinctions
between humans and other animals is the almost total lack of behavorial
templates in humans. Behaviorial templates in animals are called
instincts, and beyond a fear of heights, and quick sounds we are
without them.
The human brain is very much like a new computer, just waiting to be
programmed. But the big difference between humans and computers is
that are memories don't get erased. What a memory is, is not fully
understood. But we are pretty certain that it involves the development
of neural junctions called synapses. This development involves the
transmission of neural conductors that actually change the nature of
the synapse in a very real sense the brain, by thinking, experiencing
etc -is altered. The more a neural pathway is used (the same synapses
is used) the more conducive that pathway becomes (the faster it will
transmit). In a sense we literally become predisposed to thinking in
certain ways. (There were a few other theories floating around about
field theories and gestalt netways some 25 years ago but none of them
suggested anything like a inbuilt-template.) When we just start out,
almost nothing is programmed beyond certain capabilities to recognise
certain visual stimuli (movement, edges, possibly circles etc) that
have to do with how receptors and inhibitor neurons interact with the
synapses. There are no inherent neural templates related to learning
specific languages. An infant learns fast because there is nothing in
the way. Us seniors can have a harder time at learning such things as
language because our behavior as become so ingrained and most of us
don't go to the trouble to challenge it (burn in new neural pathways).
Think about it. You have been here in the USA for a long time. Ever
hear of anyone saying that babies born of English descended ancestry
have a much easier time of learning English than someone who is born of
Greek, or French, etc. (Children born to recent immigrants can have
somewhat greater difficulty in learning English, but that is invariably
tied into use of a non-English language at home and that is usually
offset by the childs mastery of another language). Infants/children
simply learn easier, because of the developmental stage they are in.
I have simplified Learning theory a little bit here left out gobs of
information about how the brain processes change with age etc and the
field is actually quite interesting, it was just starting to merge with
AI when I stopped trying to keep up. You may find more information and
better information about your question if you look there.
Best Regards Brent
