Unfortunately it only surfaces in one way. If I listen to a podcast while I’m doing something, then listen to that same podcast again within a week or so, I will have regular, intrusive visual recall of exactly what I was doing the last time I heard whatever passage the podcast I was listening to. The recall is synchronized down to the word with the podcast, and is vividly detailed and colorful and includes some sensation of feeling as well.
It’s weird and cool at the same time. One of these days I’d like to do an experiment where I videotape myself listening to the podcast, wait a week, then listen to it again and record myself describing what I see in my mind to test how accurate it is.
For example, I occasionally play Pubg Mobile and while I do it I ikte listening to some podcasts on a topic I do work. When it comes to apply something that I learned from the podcast I will can have a recall on where exactly I was in the game when this particular topic was discussed.
Something similar was as a teenager: I could remember when/where I learned or first heard a new word. Sadly that ability has been waning.
Instead, the material+process should be adapted to support long term memory. We know how to do it, already have spaced repetition and mnemonics, sadly teachers mostly ignore them.
The power of the market compels your good idea to turn evil.
