I've had some success with Kahne's course and its not a very widely
used system, so any time his name is mentioned I usually get
involved. Nonetheless, after years of mental training with different
cognitive systems, I have not found panacea. I have reinforced for
myself that intelligence encompasses a spectrum of mental abilities
that are limited by our genetics. Kahne must have had some amazing
genetics and unfortunately its doubtful that there is any amount of
training that could get me to his level. Nonetheless, it seems clear
to me that intelligence can be trained and it is useful to think of it
as a light whose brightness is dependent on the intensity each
wavelength that makes it up.
In this convenient light analogy for intelligence, Short Term Memory
should be considered an important wavelength and speed of processing
another wavelength, for example. For things to be well illuminated,
all the wavelengths should not only be there but they should be
individually bright. However, there are very few systems that can
effectively train the whole spectrum at once. For this reason taking
a piece-wise approach and focusing your training on improving the
intensity of specific components is very effective. This approach
takes time but at least it is an effective way to spend your time
toward achieving an end. Where does Harry Kahne fit in in this
paradigm?
If brightness of a light is lacking, it is useful to focus as many
rays as possible on one or a few things, like using a magnifying glass
to concentrate limited rays of a setting sun on a point. However,
for effective synthesis of ideas I think multiple points need to be
illuminated at once, not just one. Sometimes, the goal is to see the
bigger picture with the ant in his surroundings and not just his leg,
other times the reverse is true. This is where, for me, Kahne's
exercises come in. His exercises are excellent for developing, as a
primary outcome, executive control of attention (There may be some
secondary outcomes such as improved speed of processing and increases
in short term memory, which for seems plausible because advances in
his system require longer and longer strings of information to be
recalled, and I presume this information is being stored in short term
memory). Kahne was a freak of nature however, I'll admit that. But,
if your goal is to maximize your potential along your own potential
curve, then this overall approach is about the best approach I have
found up until this point.
With all that said, I never completed his course. But I gave it
decent run and plan on going back eventually. I did however learn
some helpful little tricks for enhancing recall, like taking a random
sentence from a magazine while sitting in a waiting room for example
and attempting to recall it backwards with the goal of being able to
recall more and more over time. Another thing that helped with verbal
fluency that I kind of got as an idea from Kahne was to repeat what I
was listening to on the radio while driving, while using longer and
longer 'caches' of words--i found this especially helpful when getting
the vocals ready for a presentation. It combines nicely with Kahne's
techniques because when presenting, your vocals are fluid and you are
able to talk and think about the next thing coming more effectively
without the appearance of losing your train of thought--its like your
words are behind your thoughts.
Again, every thing for me has been improvement to a degree. Still
don't feel like a genius, but occasionally in my day Ill have a moment
where the light bulb goes off and I surprise myself by making a
connection that wasn't possible before.
