They had me go through stuff like that with the biofeedback. Mind you, this is back in early 1980s, but I kept up with it through the years, downloading whatever I could for the DOS then windows computers for the purpose.
Mind you, some of the stuff out there is buillshit that’s being sold at high $$$ as “brain training”. Brain training for fluidic intelligence is not difficult nor is it expensive.
All you need to do is go a certain amount and then introduce confusion into the system. Let it settle, form new patterns, then confuse it again.
The techniques are old and well known but with more better graphics available now we can have immersive environments to play around in with the puzzles, the training and the confusion and regrouping activities.
Plus, we’re not limited to galvanetic skin responses and basic electromagnetic measurements of brain activity.
Now we have fMRI… marvelous machine that is. Theoretically, we could get every university an fMRI, do the experiments in fluidic intelligence training and actually MEASURE at a decent resolution: progress.
*THAT* would be worth shit canning Philosophy and a dozen other departments for.
