Hi mike_C,
Great writeup and an interesting read. I just discovered this site today as I am writing a paper for a high school class. I have a quick question for you. I've read alot of threads and the FAQ's here on this site, and they say to do what you did with biting your tongue in order to set a baseline for  control questions. But how did you know which were the control questions? Did you just bite your tongque or stimulate your nerves when you heard a question that sounded irrelevant?

Regards,
Robert.
