I understand your wish to use the light/sound machine to help you. I was very interested in Binaural Beats and such myself, and still am to some degree. The other people on this forum gave some good advice. Namely, the most remarkable thing about the brain is not that we can isolate and talk about "right-brain" "left-brain" "Slow-wave" "fast-wave", as if these give actual understanding to our mindstates, the most remarkable thing about the brain is that it constantly, at all times, acts together to create/support a WHOLE MIND...a whole experience. However, I still think that there is potential to guide certain aspects of its electromagnetic functioning towards desired states. ALS, Superlearning, whatever you choose to call it, cannot be reduced to just alpha. Even on a brainwave entrainment device your brain is still producing an incredible variety of frequencies and amplitudes...if it wasn't I'd fear for your brain's health. It's just that some researchers have found CORRELATIONS between DOMINANT frequencies and amplitudes in CERTAIN areas in the brain, and the tricky-to-pin-down state called ALS. I suggest that you play around with the frequencies and effects on your light/sound machine and see what happens- just don't let this interfere with your "unaided" practice of photoreading. You might try using a combination of beta/theta for accelerated learning. Have you followed anything to do with the 40hz frequency? You might try fooling around with that if your machine supports it. If you find something that works/helps please let me know, I'll be very interested.

P.S. Photoreading doesn't let you have immediate recall of the material, making it tricky to judge or quantify.
