I have issues with auditory processing disorder which means my hearing is actually really good, but someone talking to me seems to get a much lower decode priority than some random noise around me - if I can see the lips, even though I can't lipread, it helps me decode the speech with a much greater accuracy.

Every time I looked into this, it seemed to push the link with autism and/or adhd - back in 2008 I wasn't diagnosed so I poo-pooed the idea somewhat. Now I'm diagnosed as AuDHD.
