- I did read the article when it appeared. I'm not questioning the
- existence of transfer of learning. The question is, if you proceed by
- learning both at once will you get to the point where both can do it
- proficiently faster or slower than if you learn it with the good and
- then try to transfer it to the bad? The question is one of speed
- rather than whether there is a transfer.

-
- I am sure there is a large amount of evidence for transfer of
- learning, but that is not in question.
-
- The trouble with trying to *prove* (as opposed to accumulate evidence)
- an answer to the speed question is that one can only learn something
- once - you can't learn it one way and then see if learning it the
- other way is faster. This sort of experiment can never have a truly
- reliable control.
-
- This doesn't mean that what others report isn't interesting or that
- the accumulated evidence shouldn't be taken as the closest thing to a
- proof there could be, and acted upon. What I was saying is that
- although you can't formally prove anything, the body of evidence is
- probably a pretty good indicator of how to learn quickly. Of course
- one could counter that it just boils down to the particular individual
- and the particular trick (not to mention a million other variables).
- That may well be, but I am interested in the generalizations about
- learning speed vs learning method that can be drawn from our
- collective experience. Something like that.
-
- Perhaps you might phrase it as: To what extent should one rely on
- transfer of learning to speed the learning of both hands? The
- conclusion that might arise is that one should rely more heavily on it
- (as opposed to learning both hands simultaneously from scratch) when
- it is known beforehand that the trick has some quite distinctive feel
- or rhythm etc that one needs to "get" before it can be done. Perhaps
- this could be phrased as the almost tautological: Rely on transfer of
- learning more than learning both from scratch when there are manifest
- things that can be transferred. Sounds a bit boring, but, assuming the
- previous to be right, what kinds of tricks have significantly more
- that can be transferred in this way? I feel it's the ones that have
- some particular aspects about them that one can conciously recognize.
- If this is so, it would be nice to have an idea of how best others
- have found learning a particular trick. For instance, that a lot of
- people find learning to ride a uni one footed with either foot is best
- done by transfer of learning.
-
- Enough...
