SV: Protocol Decision Trees

Pete,

What would you prefer? Reward

band range, or reward band range % of 2-42 Hz?

Bruce,

Good explanation. I think the biggest issue for many people

(including, if I recall properly, the question that started this thread) is

client recognition of when exactly one is " there " . I've done

this with a number of clients who were simply not able to tell me that they

suddenly felt so much better--or worse even sometimes. It seems that,

assuming Sue is always able to find it (which we assume based on hearing always

about her successes), she has a huge amount of experience that most trainers

don't have, so she is perhaps able to " see " things in a client's

response that most trainers would not. Hence the desire for something in

the EEG that might help identify having found the spot.

Another question that often arises is " how long do you stay at

each frequency? " The idea of shifting up and down the range is not

to hard to get your head around, but do you stay at a particular band for 10

seconds? 10 minutes? And, in the older days, there was a 3 Hz band for

reward, which now, I understand, is sometimes as low as 0.5 Hz. So we

can't just start at 12-15 Hz and slide the band down to 11.5-14.5, to 11-14,

etc. Because the sweet spot MAY be 0.5 Hz to 1 Hz (a band, by the way, at

which the delay between an event happening in the brain and the brain receiving

feedback on it--even with the very fastest filters--is likely to be several

seconds!), I'm stumped as to how one decides how wide the band should be, how

long to test each one and where exactly it is, unless I get one of those

clients who can TELL me, " oh yeah! That's it! "
