It's not hard to find examples of highly creative forward-thinking adults who seem to have had this prodigious memory pattern (Nikola Tesla, Isaac Asimov, Leonardo Da Vinci etc.) but amazingly we think we see some of these budding versions in our clinic because of our interest in highly gifted and twice exceptional (gifted with LD) learners.
Vivid personal memory doesn't always translated into academic success in the early years of education - because it's usually impersonal or rote memory that's emphasized in school. Vivid visualizers can be easily distracted, lost in their daydreams, or more concerned with personal trivia (what Toby brought to school, the games on Sarah's DS, etc.) or personal experimentation (homemade catapults) than the steps for rounding decimals or regurgitating dates and names for a history test.
