I'm in a weird position to give you advice...see I took some speedreading courses, so on small passages like that, I
do incorporate a type of speedreading system of my own.
Rapid reading won't help you on the passages for the SAT, because you'd need the 20 minute incubation time anyway. I guess you could use a type of rapid reading without photoreading, but you'd be going slower.
Hmn...that probably wouldn't work...see, the reason I think rapid reading works with photoreading is that you'll intuitively know what parts to speed up or slow down, since it's in your subconscious.
I would say that you may be right, and speedreading could be the best application for the scenario you're stating. =\ It's a pretty specific scenario, you have to admit.
I hate to recommend speedreading, because from what I've seen, speedreaders have a very hard time switching to photoreading, (though I didn't, and another guy who used to be on here, Andy, didn't either).
I'll give you a rundown, and see if this helps you in general. This way, you don't really "learn" speedreading, but you learn some techniques that help:
1) Run you finger under each word you are reading, and keep you finger moving at a steady rate. This is the Evelyn Woods method to retain some comprehension, because you focus on the word above your finger. NEVER go back if you miss something - it builds bad habits.
2) Notice any subvocalization - we have a habit of "reading" words out loud, even though we don't really use our mouth; I think I read somewhere that scientists attached a meter to some people voiceboxes, and they were actually flexing in motion to the words, even though the subjects weren't reading out loud. My guide is, if you can kind of imagine a little voice in your head reading it, you're subvocalizing. It slows you down, so try to minimize it.
3) The more you read, the more you become familiar with words. Take the word "fantastic" - when a 1st grader reads the word "fantastic" he sounds it out, and goes very slowly. By sixth grade, he say it normally. If you practice, it stops becoming a "word", it becomes a symbol. After practice, "fantastic" isn't the word "fantastic", the letters are just kind of a symbol that you associate with the idea of fantastic. It's a hard concept to explain, so I'll try doing this. For a first grader, he sees f-a-n-t-a-s-t-i-c, letter by letter, which spells the word "fantastic", which means incredible, and he then incorporates that into his context of the reading. If you practice, "fantastic" is like a picture that you already associate with incredible, so cut out the "letters making up a word meaning something else" process, which actually does slow you down. It's easier with hi-frequency words like "the" "he" "she" "is" but after you practice it becomes second nature - without photoreading I'm still a fast reader.
Those are the three best tips I can give you for faster regular reading (the first step is part of a speedreading concept). I hope it helps. Good luck on your SAT's. =)
