I recently came across a description of autistic brains as "bottom up" processing and that really fits me.
They describe neurotyoicals as having "big picture" oriented brains. They really quickly start filtering out anything that doesn't suit what gets identified as the big picture in their mind.
Autistics, otoh, are more often "bottom up" processors. We see ALL the details and have to sift through them to construct what we see as the big picture.
