Just a few thoughts,
With the exception of a few extreme cases of general arousal, such as
sleep or extreme agitation, I think you'd be hard-pressed in most cases to
correlate subjective psychological states well with EEG measurements.
There were the flashy EEGs reported by the folks who studied meditators in
the 1970's, but there are some very onerous methodological problems in
doing that kind of analysis, as you probably well know since you seem
familiar with Gevins. I think the trend in research for the most part has
swung more toward EP, ERP, MRI, and PET and away from trying to analyze
patterns in the gross EEG and correlate them to sophisticated mental
activity. Also toward studying simpler behaviors rather than states of
consciousness. That's just my own perception, of course.
Not that it isn't potentially worthwhile, just that there are probably a
lot of other things that we don't understand that we have a much better
chance of understanding in the near future. EEG analysis of subjective
consciousness involves a lot of speculation and frequently the tracking
down of phantasms, IMO.
Elmer and Alyce Green and Maxwell Cade probably represent the height of
the earlier interest in EEGs, but that material is quite dated.
kind regards,
