When I look up photographic memory techniques, I see a lot about a "military method". I think it's best captured here:
This method will take you at least 1 month to develop. You must also practice it every day because one missed day will set you back a week.
Step 1: You must be in a windowless, dark room. You need to be free from distraction with only a bright lamp in the room.
Step 2: Sit in a position where you have easy access to turn your light on and off without getting up. Next, get a piece of paper and cut a rectangular hole out of it.
Step 3: Now, get whatever it is that you’re trying to memorize. Cover it with the piece of paper, exposing only 1 paragraph.
Then, adjust your distance from the book in a way that your eyes will automatically focus on the words instantly upon opening.
Step 4: Next, turn off the light and let your eyes adjust to the dark. Flip the light on for a split second and then off again.
By doing so, you will have a visual imprint in your eyes of the material that was in front of you.
Step 5: When the imprint is fading, flip the light on again for a split second, while again staring at the material.
Step 6: Rinse and repeat the process until you can memorize every word in the paragraph.
However, I cannot find any information about the military trying this or any studies confirming that it works, much less the claim that one missed day will set you back a week.
A similar question about the validity of this method was also asked here, which includes additional links that reference this "military method".
So there are multiple independent questions:
- Did the military, at any point, try any method similar to this?
- If anyone (including the military) has tested this method, did it appear to work?
- Is it true that missing one day of practicing this method generally sets one back by an entire week?
