Hmm...

I need a good word for that affect/presentation in which one is a wee bit too serious, slightly agitated, quite frank, slightly entitled, basically calm and collected but in an ever-so-slightly heightened arousal sort of way, talking slightly fast yet clearly and with every other word or so in bold or italics, and really really wants to make sure you know that everything they're saying is quite important to them.

You know, the one where 99% of the occurrences of it are from people with Asperger syndrome.

Everyone knows exactly what I mean, I'm sure, but I just don't think I can quite describe it that way in a report.
