Actually, when you PhotoRead and activate, you are using "speed-reading" types of techniques....in reverse.
Instead of pushing your eyes faster across the page, trying to cram 7 chunks of information into your brain through your conscious mind, hoping something sticks, with PhotoReading you learn to absorb all the printed text into your brain at a page per second. Then, building comprehension from "whole-to-parts" you trigger information out in layers by connecting with the printed text visually with SuperReading & Dipping.
And, its the Mind Probing questions and your purpose/outcome statement which cause your inner mind and intuition to guide you to dip into dozens of parts of your book, answering those questions.
