For this Channel Set:
Note 1. We have tried to include the most commonly used bandwidths and ratios used
for NFB plus a few ratios that may help you follow client progress.
Note 2. For each bandwidth there is % of total power, a damper, pk-pk +damper (for
controlling speed of feedback) and statistics, namely: means, %>C (to set % time
>threshold constants), standard deviations, variability. The damper is used to slow
down movement of bargraphs so the client can follow them more comfortably.
Note 3. For each of the BFB variables there is: max, min, mean, SD, variation coefficient
(variability).
Note 4. The 2 channel NFB channel set has to include the major band widths and ratios
but omit some of the other variables due to the 254 channel limitation.
Objectives
Our objectives in providing these display screens are:
(1) to give clinicians a range of displays applicable to young children, adolescents and
adults
(2) to give Experts basic screens they can modify to meet very specific requirements for
individual clients
(3) to offer trainers who are beginning a NFB practice a sufficient variety of screens to
cover the most common training needs of their clients
Screen Complexity
Note: Some trainers will correctly say that there are too many ‘instruments’ on most of
these screens. The answer to this is as follows:
(1) Many clients want a lot of information and want to make their own choice about
which of the instruments (bargraphs etc.) they follow in any section of their
training session. Our experience with a widely used two monitor (client and
clinician) feedback system has repeatedly demonstrated that even young children
often find the clinician screen much more interesting than the games on the client
screen. Some even follow the raw EEG, which gives them instantaneous, accurate
feedback. The “universal” group of screens will meet this need by allowing the
trainer to put on the client monitor that which is most helpful (and desired) by the
client.
(2) When the client or the trainer wants to eliminate information from a screen this is
easily and rapidly done by clicking on View and Hide and click on the instruments
you want hidden(see Appendix). Alternatively the trainer can click on ‘edit
screens’. The trainer then right clicks on each of the instruments that are to be
deleted and deletes them. Then the trainer clicks on file and save as and gives the
screen a NEW NAME. In this way the original screen is not lost.
(3) In this program it is much easier to eliminate unwanted material than it is to build
screens from scratch. Therefore we have attempted to give you as much
information as possible and let the user delete that which is not needed as they
customize screens for clients. We have also provided a “Universal” screen. This
