it depends on which kind of memory with me... my episodic memory (memory of events and actions) is practically nonexistent, but my semantic memory (memory of information) is nearly eidetic. for example i remember what happens in a book and can quote bits of it after the first reading, sometimes i remember when and where i read it but i never remember the act of reading it. or another one, when i was in high school i would draw geometric tessellations during class, with a separate note book for each class, when i look at the tessellation i remember everything i heard when i was drawing it but i dont remember the voice that spoke it... its all in my voice. what episodic memory i do have is mostly nonvisual, for example, when i remember a conversation i had with someone i dont remember a "movie" but a "script" of what happened. the only visual memories that stick are ones that provoke a strong negative emotional response... and dreams. everything else is rendered down to "verbal" information strings... but the verbal "sensation" i get is not the sound of the word but the tactile sensation of speaking it. which is why i constantly subvocalise... i find it hard to think without that tactile component. i find it nearly impossible to visualize things in my mind unless its a map, its like i have a GPS in my brain... but it crashes in some places like hospitals and malls. i have an excellent memory for music and can play songs in my head like cd, but im terrible at playing instruments and music for the most part, is the only auditory memories that i remember like that.
but i do not think of myself as a linguistic thinker but a systemiser that "codes" in language, because i am better at mathematics than language arts... math is more precise so its easier to "translate". i find human languages irrational and "slippery"... too blunt of a tool for such delicate work as conveying my thoughts, or anyone elses for that matter... to define is to confine. for me anyways, NTs have a way to add nuances of meaning that look for all the world like telepathy, it isnt, it just looks that way. the only way i come close to that kind delicate precision is by selecting and assembling the words in a manner that causes their "textures" to blend in a way that conveys the nonverbal tone of the word structure... it works best for me in poetry, but i cannot compile it fast enough for everyday conversation. but i never quite get the full measure my thoughts into anything... not even a picture.
holy wall of text Batman... sorry about that i am just trying to be as precise as possible.
