People might get confused about this thread because there's "faceblindness" which is prosopagnosia which is the inability to recognize a person by face, and then there's a totally separate issue of being unable to read faces. (And then there's something about whether looking at a face causes the "face area" in the brain to light up. Which it does, for nearly all autistic people. Studies that said that it didn't, were studies where they were testing autistic people without bothering to check whether the autistic people were looking at faces or something totally different! Talk about confusing.) Which are three distinct (although sometimes overlapping) issues.
I really don't know whether I "read" body language or facial expression or not. I know that I get a lot of highly accurate information about people based on things as simple as the way their foot hits the floor, the level of tension when they take something from my hand, things like that. But I kind of doubt I'm reading the same cues, in the same way, as nonautistic people do.
