Well Well Well there are several things that I think happen:

1. First off we on the spectrum in general have difficulty picking up emotions or appropriately identifying which one the person is displaying at that particular time. A problem that causes major mis-indentification of emotions for us is that according to the standards laid out by society there are just emotions that we are not allowed to display or talk about. For us we find this very unusual because unlike most people when basically say it how it is pretty all the time, which just isnt a acceptable thing to do according to those neurotypical(not on spectrum) people.

2. Second when people on the spectrum do feel or sense other peoples emotions even if the person is trying deny it, we tend to have a lot more of a response to peoples feelings. This is because of all our hypersensitivity issues, imagine for example your hearing is extremely sensitive to certain things. I for one even though I am almost 21 still hate it when people vacum the floor or when the bass setting on the radio is turned up to even what most people would call normal levels seriously bothers me. The problem is even though we do have hypersensitivity to picking up emotions, reading and interpreting them is something from basically the opposite side of the skill spectrum for emotions. It basically comes down to the fact that the emotions that we usually pick up on are strong or negative even though it may not seem as bad as we think it is.

3. Final thing that I want to say which complicates feelings and emotions for people on the spectrum is that pretty much no matter how hard we try it is extremely difficult for us to hide or mask our feelings from others. This creates problems because most people even some of your closest friends dont really want to know the exact feeling you are having, or the supposed intensity based on facial feature recognition that neurotypicals is which is normally way different from how our intensity scale works. For example when I feel that I am irritated according to others my face appears mad and not only irritated like I really want people to know.

Finally yes facial feature recognition and display is something that we all can improve on but the problem is that we develop this school a lot later than most do and at a time where most neurotypicals would find to be inappropriate. In my personal experience even though this is something most 14 year olds would be able to do effectively and appropriate still for me hasnt yet occurred and Im almost 21, so I guess that things will eventually get better it will just take a lot longer and a lot more effort to learn than most people have to put into it.
