I chatted with Paul to see what he had to say.
"To always have an optimal anything for everything is impossible. (Violation of
the meta-model, remember?) But more to the point, Optimal Learning doesn't necessarily happen in this moment and then it is done. There are studies that show retaining information requires that you come back for review on several subsequent occasions.
"Sleeping seems to release a buildup of adrenisone too, but what that has to do
with learning? I have no idea."
Paul's also a napper. Plus, he said, "I think that any Paraliminal including the 10-Minute Supercharger can lead a person
into deep theta or delta brain rhythms. Those seem to be the consolidators. I feel that 10-15 seconds in delta is enough to produce a tremendous benefit to my brain."
