[sci.research] How to measure learning ability?

berke@CS.UCLA.EDU (08/27/87)

I am involved with a project part of which is to  teach  mime  to
learning-disabled  children.   I maintain that:  Mimicry behavior
is integral to or forms the basis for animal learning.   Directly
training   mimicry   should  therefore  directly  train  learning
ability.

This is a simple, to me, an obvious claim.  The question is,  how
to determine whether it is true?  If you can answer the following
simple question, I would appreciate hearing from you:

Question 1:  Are there any measures of general  learning  ability
that  are  commonly  accepted?  If not, what measures of learning
ability do you use (or know of), whether they purport to  measure
verbal  learning,  skill  acquisition, or any other behavior that
can be classified as learning?

In "cognitive science" and related fields there is a lot of hubub
currently  about new and better brain models. I have my own which
I call Network Recombination. I refer to "learning and memory" as
a  unified process of learning/memory because of the implications
of my model. If you ascribe to a  model  of  how  brain  activity
produces  the  phenomenon  of  learning/memory  (or "learning" or
"memory"  separately),  I  would  appreciate  an  answer  to  the
following question:

Question  2:   Does  your  model  make  any   predictions   about
intermodal  transfer  of abilities? Specifically, say a subject's
verbal skills are poor and so she does poorly on vocabulary tests
which  Thorndike  (in  Human Learning, 1931, p.174) considers "an
excellent intelligence test."   Say I now train  the  subject  in
physical   skills   to  increase  discrimination,  analysis,  and
creative abilities (defined primitively below).   How  much  will
these  abilities transfer to verbal or quantitative skills?  What
form will the transfer take?  Or will there be none?

  Discrimination ability - seeing different parts in observation

  Analytical ability - breaking things into parts

  Creative ability - putting parts into new wholes

I appreciate all opinions and advice, especially from people  who
have  worked  with learning-disabled children (and even more from
people to whom this posting  seems  based  on  my  ignorance  and
misconceptions).   But I would like to specifically request those
putting forth "mind models" for predictions of their  models.   I
would  like to QUANTIFY increase in general learning ability, and
so the predictions of specific models with specific properties is
necessary.

If there is no such thing as general  learning  ability,  then  I
would  like  to  QUANTIFY  transfer of abilities from physical to
verbal or intellectual skills, or verify that there is none.

Can you help me?

I have posted this to several news groups.  Perhaps it  would  be
best to reply to me in e-mail, or to decide on a single group for
follow-ups, perhaps sci.research.  It has little traffic.

Thank you in advance for all replies.

There's a large body of research that suggests that this is not true.

And like many "simple, obvious" claims, it nmay not have any basis in fact.

The experimental analysis of behavior?  Have you read any?  These
are basis research methods in behavioral science.  What's your
background?  It doesn't sound like it's psychology.

Again these are basic questions of cognitive psychology.  Have you read
at all?  Do you think folks on the net produce less "hubub" than the
published literature contains?

Right. Anecdotal evidence is always better than research data :-).

Nope.  I gave up on this field years ago.  I can only state that I
agree that cognitive psych. is more noise than substance.  As for
"brain models" in general, they're good at helping cognitive
psychologists understand computers (it's curious that mental models
have paralleled the development of computer architecture, not the
other was around.  Computer hardware isn't sophisticated enough
yet to provide the models that cognitive psychologists need to
model the brains of even simple organisms.)

Psychology is a field in which you can have a lot of success.  All
you have to do is come up with a model, and then design research
that supports your model.  That's easy and rewarding.  The hard thing
to do is to design and conduct research that actually _tests_ your
model.  There's no incentive to do so.  Grant money, tenure, even
getting your degree (I assume from your inquiry that you're still
after one) depend on producing research _results_.  Until that
changes (unless we get lucky) psychology is a nowhere field that
produces little of value.

>follow-ups, perhaps sci.research.  It has little traffic.

Cognitive psychologists can flame to /dev/null.  I only listen
to opinions I already agree with :-)
