I am certainly analytical, I get good grades in Psychology and have an ability to switch off my emotions and do pure logic if required. I have possible AS myself, certainly i think I do, everything I have read applies to me and my DH would agree.
Dh gets his kicks from building unique electronic circuitry, which he then sells. I also like electrical stuff: it has rules and makes sense. It doesn't do things you don't expect it to.
A lecturer last year (Psychology) told me that kids with ASD have at least one parent (typically) with a Maths ability. Don't know if that is research or not, but certainly DH's family.... bil likes his electronics too, though restricts himself to the sound side of it; FIL taught them all it.
