Val,

That is very interesting. It makes sense that standardized scores, norms, averages etc are not compatible with NDS based neurofeedback. It seems that to use these as a reference point would actually inhibit the transformational process. After all nothing stays the same and to formulate ideal brain states or norms as the goal sounds limiting and akin to the Buddhist notion of grasping. I think this is also one of the limitations of entrainment methods.

 

I also take your point about why you do not wish to participate in the linear and classical based conferences. The people attracted to them as participants are most likely to come out of that framework and yes they would find your information very challenging. I look forward to the time that we have NDS based neurofeedback conferences. That would be fantastic.

John

John,

So here's the thing. What they do, and what they present on, is either something we already done (and have done for years) OR it's completely irrelevant to what we do, meaning it simply isn't relevant.

So, for instance, now the big buzz is (apparently) z-score based training. And it's not bad, at least in some theoretical ways. There are problems with it though, esp in how it's actually implemented. For one thing, a z-score is a linear mathematical concept. NLD/NDS mathematics work much better since we are actually dealing with the CNS and it is clearly NLD/NDS. But the other real problem lies with the idea that there is an "ideal" central tendency for ALL brains and that training needs to be oriented towards migrating EVERY brain back towards that central tendency, wherever that brain happens to be.

It is a slight twist on the Lake Wobegone idea that "all of our children are above average". Most people are so seduced by Gaussian stats that they really do believe that "average" means something important. And, therefore, being ABOVE average might be even better; so Peak Performance means being "above average" rather than "at your personal optimal level".

A related issue is that it's really clear that the "norms" aren't useful, esp not for the purpose of neurofeedback training. At best they give very clumsy "guides" for what might be useful for some severe deficits, but the truth is that there simply isn't enough data to support those "guides" from the point of view of real normative database statistics. We're still probably 10 years away --at best! -- from having that level of data collected, collated and analyzed in meaningful ways. And, even if we DID have that level of data analysis, neurofeedback is done using different technology than the data that is collected and submitted for QEEG-based analyses so there would still be a real question as to how useful the QEEG-based conclusions would be when applied to fundamentally different data (ie the data actually used during neurofeedback).

Similarly, "protocol-based" decision making is irrelevant to what we do. Our comprehensive, adaptive targeting "covers the waterfront" AND adapts itself to the Client's real-time training data AS training happens. So what choices are needed?

So the overwhelming amount of information presented at those conferences is really of no use whatsoever to how we do neurofeedback training.

Now let's turn the question around and ask can presenting what we do at those conferences be useful to others? And the answer to that is, most likely not at all. The real reason for that is that what we do can ONLY be done using NeurOptimal. No other system can work in the same way. So what would others learn? Basically that they would need to replace their current equipment (or at least extend it with a new purchase) and how much do you think others want to hear that? Esp if they've already invested heavily in an alternative approach, and esp one that relies so much on expensive diagnostic or assessment procedures?

It's just too cognitively dissonant.

That's a real shame IMO but "that's the way it is", to gloss Walter Cronkite.
