I've seen two types of Asperger's, one type does not really respond with much emotion to other people's emotional display. But if they can get info about what the other person thinks and feels through words, they might be able to get a good cognitive picture of that person's state of mind.

The other type has a hard time mapping out others. But instead they have the instinct to immediate reflect the other person's expressed feelings within themselves.

There are other variations of course. But these are the main two I see.
