Okay, so girls who have autism, PDD NOS, HFA, Aspergers, etc. have flat a-fect a lot more than boys with Autism. I am not sure why, but they do. Not all Girls with Autism have flat A-fect, but the majority do. This is purely from what I’ve seen, so this isn’t scientific fact.
Why is this? Well, one theory I just came up with is that the hormones and biology between Boys and Girls are very different. Flat A-fect could affect girls more than boys due to autism and hormones, but that’s just an unproven theory. More of an idea. People with flat A-fect do show plenty of emotion in their voice, but it is harder to hear, unless you are used to people with flat a-fect. Anyways, this is just what I’ve seen, maybe i am incorrect. Maybe I am not.
