Bant there is something I discovered idk if there is a term for it in psychology/neuroscience, but if there is please tell me about it. I just remembered that grandmasters in chess have exceptional ability to remember chess board positions, but only if it wasn't nonsense, none of it transferred to non chess related things. There is an autist who could draw his entire view in just one helicopter flight with perfect detail. Also there are people who can memorise the exact pitches of melodies and songs that most people wouldn't be able to remember much. Like their brains are more able to remember music.

I think I will call this concept specialised skill memory. I wonder how one would go about to develop it, you would need insane amounts of hours.
