Psychology Experiments

I'm excited...later this week, I'm going to have the chance to participate in several psychological experiments! It's one of the requirements of my Psychology class-- I have to volunteer for various experiments to help out the department get a full collection of participants. As far as I can see, my part is going to be easy; I mean, I don't think that its going to be anything like the Milgram experiments or anything. (at least, I hope not :*)
