It’s been stated that we all have some degree of a photographic memory. It is the ability to picture a scene in your mind. Granted, definitions can get stretched. Here’s two examples:
a) Suppose you lose your keys, but you can clearly “see” in your mind exactly where they were last. “It was yesterday in the kitchen. They were on the butcher-block counter top next to the fridge. Mom was standing by the window over the sink rinsing a brown stain off her blue blouse since she spilled coffee on it. Oh, yeah! And the keys were bumped off the counter by Jimmie’s ball knocking them into the gap between the counter and fridge. And, here they are!” Some of us will recall more details than others.
b) Another form of photographic memory people speak about more often comes from reading and studying. Some people have a better ability at remembering not just words on a page, but their relative positions…like they can actually picture the whole page in their minds.
Once, I had to remember a speech in a foreign language for a class. I spent days studying from a photocopy with the words on the page starting at the bottom of one column of text and continuing on to the next. I could picture places where the words were lighter than others, etc., due to the quality of the photocopy.
Then, during a trial run in front of my class, I got half-way through and then my mind went blank. When shown the text, the lay-out of the page was totally different. It really threw me off even more!
I’ve had the same experience with practising sheet music from one book and trying to play from another. It’s a subconscious act. I should be meorizing the notes, but the mind seems to link the data with the data’s position on the page. …So, I’ll always bring my own version to be safe - THE version with which my mind’s eye is most familiar. Maybe you’ve experienced this, too?
Ok, this second example is a degree of a photographic memory, too. Although, I wish I could use this skill to the ultimate degree - reading text from pages in my mind’s memory. As you can see, it can sometimes work against you.
Just from my experiences and readings on the subject…
