Trauma and auditory processing: Stephen Porges (polyvagal theory) writes about how people in fear states are more attuned to low frequency background noises (danger! lions! growling!) and less sensitive to the higher frequencies of human voice. 1/

Opposite for people in social engagement mode - more sensitive to voices, less to low frequencies. Porges explains this tradeoff anatomically, in terms of how the brain regulates middle ear muscle tension: 2/pic.twitter.com/f9gt51xNja

Porges also ties this in to auditory processing issues -- some folks with PTSD, autism, etc find it difficult to extract voices from background noise, while simultaneously feeling hypersensitive to other sounds. 3/

I put a short excerpt on this theory of auditory processing & trauma in a Google doc (from The Pocket Guide to the Polyvagal Theory by Stephen Porges). Very interested to hear what y'all think! Especially re: competing theories, other evidence, etc https://docs.google.com/document/d/1eebyGpxsiME00vm5UpsOYIyi7TY-DDp7l-nxl8dhvHE/edit?usp=sharing … 4/

Replying to @SarahAMcManus
I find this a really interesting parallel, which I learnt about from
@mykola - although as I said to him I think it's worth avoiding the sloppy thinking of 'oh the audio processing isn't an autism thing per se it's just traumatised autistic people' - which doesn't stack up IME.1 reply 0 retweets 0 likes -
Yeah, I'm very much wanting to understand more about how different factors contribute. And how it ties in to more general research on the "cocktail party effect" of picking out one audio stream from background noise: https://en.wikipedia.org/wiki/Cocktail_party_effect …

Replying to @SarahAMcManus @misen__
Yes. IMO we need more research on specific reported subjective traits. Do tests, believe people. “Autism” and “trauma” are words that each contain volumes, much of it contradictory. How do we even start to unpack it all?

Looks interesting! Although I don't currently want to make time for it, I'll make note and may get to it at some point.
