I saw this post on x-twitter that explains this phenomenon which I really relate to:
ADHD and other auditory processing challenged brains will have a delayed ability to process auditory inputs.
But the brain has a pretty nifty feature that stores up to 2 seconds of auditory information… it’s called the “phonological loop”
So, when a brain that struggles to process auditory info takes that info in… even though there’s a delay in processing what that info means… it stays accessible for a short time to be processed when the brain is ready.
Cool, no?
IIRC its also common for folks with the 'tism as well. There are a few other sources for this, none of which I can think of at the moment.
A lot of “ADHD” and “Autism” things are actually normal human behaviors but amplified.
My partner is “neurotypical” (inasmuch as that’s actually real) and has some “oh that’s autism/ADHD” behaviors that are similar to my ADHD but nowhere near as severe.
Humans are a weird bunch. Most of us are normal. Some of us have exaggerated behaviors compared to baseline, but that doesn’t preclude baseline from exhibiting similar behaviors.
