Calling all 12 year olds

I've been analyzing data from the Memory Test. The response to that experiment has been fantastic, so I'm able to look at performance based on age, from about 14 years old to about 84 years old. Interestingly, by 14 years old, people are performing at adult levels. I have a few kids in the 10-13 range, but not quite enough. It would be nice to know at what age people hit adult competency.

So...if you or someone you know is in that age range, I'd like a few more participants in the near future. I should actually be able to put up a description of the results relatively quickly in this case, should I get enough participants.
