Write down how many lines they have read. Most people see the whole tree in one or two glances. This is what we call Natural Vision. When we are seeing almost anything, we are using Natural Vision, except when we are looking at a page of print. You see, in first grade we were taught how to have tunnel vision.
Most people can only see one word at a time.
You may as well read through a straw. Tunnel vision is unnatural and fatiguing to the eyes. You need to look at a page of print with more Natural Vision so that we are seeing several words at once. In fact, let s pretend that each page of print is just a picture of a tree, with each word being a leaf. They are just to SEE the words.
