Experimental virtuality in a rich myDi-environment

~*~
DOES
an enriched environment
or an impoverished environment
alter learning
ability?
-
ALTHOUGH
some studies suggest that experience in an enriched environment usually improves subsequent learning,
the effects are often
short-lived!
-
EARLY enrichment
may improve subsequent learning of one task,
have no effect on another task and actually impair learning in a third ...
PERHAPS we should not expect much transfer of capacity among entirely different kinds of behavior.
NOR should we expect experience in an enriched environment to lead to an increase in 'general ability';
EVERY environment is specific and SO
are abilities?!
-
IT
has been shown
that early problem-solving in monkeys may have the deleterious effect of fixating infantile behavior patterns;
SUCH monkeys may never reach the efficient adult performance that they would have attained WITHOUT the early training.
But AGAIN, this result is specific and should be generalized ONLY
WITH CAUTION!
-
FORMAL training of rats,
such as teaching them to press a lever in response to a signal or to run a maze, produces changes in brain anatomy & chemistry,
but the type of training seems to determine the KIND of changes.
Changes in brain weight and in the activity of acetylcholinesterase &
chlinesterase after prolonged training of rats were found, but the pattern of changes is different from what what others found with enriched and
impoverished environments.
-
IN our laboratory
we have given rats daily formal training in either operant-conditioning devices or in a series of mazes for a month or more and have found changes in brain weight & brain enzymes.
THESE CHANGES, however, were rather small and also had a pattern different from the changes inducec by environmental experience.
THIS is clearly a problem that requires
MORE RESEARCH?!
