Thinking about this some more...
I was reading one of Michelle Garcia Winner's books with dd today (Social Fortune or Social Fate). This one is a graphic novel geared at teens and tweens. The intro made the point explicitly that excessive laughter is not socially acceptable for this age group. So, I wondered if your dd understands that on an intellectual level, and it's just the physical/emotional control that is lacking, or if the social ramifications still need to be explicitly taught.
The rest of this book does not deal with the laughter issue, but it is very good at showing social consequences of different choices. As a bonus, dd thought it was (mildly) funny, so she didn't reject it out of hand.
Anyway, if you haven't seen Winner's materials at Social Thinking, you might find something useful there, especially if this isn't purely an emotional regulation issue.
