Hello
You pull your trigger words when previewing a book. It should take a beginning photoreader 5 to 8 minutes to preview a entire book. You pull 20 to 25 trigger words for a book.
You definitely do not want to spend no more than 8 minutes previewing a book. The problem you get into when previewing more than 8 minutes is that you get ensnared or trapped in a traditional, passive reading mode.
You do not want to get into a lot of detail too soon. It just turns into regular reading.
After you have pulled your trigger words you want to do a review of what you have gained from your survey & your list of trigger words. Also after you have done this review you decide if you need to change or modify your purpose.
The core concept of photoreading is layers. Doing a brief (5 to 8 minutes) preview of a book & pulling trigger words is one layer. Photoreading a book is another layer. Doing superreading & dipping or skittering is another layer. Mindmapping a book is another layer.
Learning takes place best when learning in layers.
