I've heard the female screech pretty much all over western societies. I hardly ever hear men do that. So I was just wondering.
As an autistic person, noises trigger me, and that's why I noticed females doing it more than males.
If it is conditioning, it's something particular to western society, I suppose.
Well imagine a car accident happening while people are walking on the sidewalk. There's always a couple women doing a high pitched screech out of shock. However I hardly ever hear men do it when it's almost gueranteed to trigger this response in women.
