Hello Rob and ListMates,
Thanks to Rob for bringing this to everyone's attention.
While many are involved in the technical aspects of building the interface,the software side should receive as much if not more attention.
The underlying issues Rob brings up in his post are very, very important tosuccess in providing the reinforcement in operant conditioning. How engaging the feedback will no doubt be shown in future research to be a crucial, if not critical ingredient in achieving moving the brain into the desired condition.
Speaking of states, while the technical aspects of circuit design are beingformulated, it is also important to look at several aspects of the feedback itself. The timing of the feedback is nearly as important as the content of feedback.
Remember too, effective eeg biofeedback is operant conditioning viz. a vie Skinner--not Pavlov...big differences. It is also important to examine and understand the difference between "state training" and operant conditioning. Hypno-therapists and others do "state training." In eeg biofeedback, we do operant conditioning...else when the person is off the machine and out ofthe training environment he leaves the "state" achieved back there.
Thanks again to you Rob for bringing this important information to our attention to digest and incorporate. Marvin, the "Tetris Master, says "hello."
Best regards to all,
Grant

Actually, video games are engaging for far different reasons than even the
most stimulating neurofeedback display.
I want my clients to remain engaged in the process. If an engaging
display,
game format, interesting sounds and visual feedback encourages that
interest, then I'm all for it.<
Funny you should mention video games. For about two years now, I've had a
growing itnerest in the science of STORY-- structure, elements, dynamics,
hero's journey, etc.
To that end, I have actually begun organizing a meeting for writers,
screenwriters, narratologists, mythologists,algorithm and game developers
on the Science of Story. (Late September, 2002 LA, CA) and already have 16
speakers.
That's where this post comes in. I just reviewed a realvideo lecture on the
use of story in games, and it seems that the better games do have stories
woven into them.
Simpler games just have shooting and fighting, but when it's possible to
put characters the game player can relate to, and challenges which engage
the player, games retain their interest and "replay" value longer.
This is an aspect of biofeedback software that has yet to be developed. I
can imagine characters who go through different adventures, who gain powers
or new weapons after reaching certain criteria levels with biofeedback,
(current score keeping could provide the point counts. )
One consideration in good story development is that the protagonist and
other main characters go through a "character arc" of personal growth or
change (sometimes for the worse.)
One example of this in biofeedback is by the Israeli firm, Ultramind,
headed by Tuvi Orbach, in which a sea creature, as it performs better w ith
GSR feedback, evolves to a land dwelling human. I'd be curious if I am
missing any other examples. It seems most of the animation biofeedback out
there consists of simple cartoons or games which just keep score, rather
than more sophisticated plots as I've described.
It seems to me it ought to be possible to build in character "evolution"
over sessions, using across session data as well as real time feedback. The
evolution might be in the form of getting access to more powers, faster
response times, higher "levels" of the game, etc.
Just a thought for you software developers out there.
