Hi all...
I was looking for Paul R. Scheele books on Amazon and ran into a "review" of the PR book. This gentlemen was saying that eye physiology negates the claims made to the effectiveness of PR because of the arrangement of rods and cones. The underlying statement was that pereipheral vision was insufficient to produce enough clarity in the words on the page for it to make a lasting impression on the mind.
Then I remembered my days in the Marine Corps. During a night ops training exercise, our DI taught us about night vision. He told us to try to hard focus on an item about 20 yards or so out into the noght. As we did, the item was difficult to see, and even sometimes seemed to dissappear into the dark. Then, our DI told us to open our visual field by looking at the entire landscape, and to bring the item( If I remember right, it was a pole with tires around it) a little outside the center of our field of vision. Amazingly, the item was very easy to see, and actually quite clear, considering we were not actually hard focusing on it.
Clarity of peripheral vision is really a proven biological fact. When we learn to open our field of vision and train our eyes to see peripherally, we can really see and receive quite a bit more.
