Alright, if you are a FSU student, you can go to www.xsfs.fsu.edu and click the "sign up" link on the right hand side of the page. Use your FSUID, NOT your SSN when you sign up. You are guaranteed $10 if you sign up for an experiment and you show up on time. During the course of the (roughly 2 hour) experiment, you can earn more money. How much more money? Well, I'm not allowed to tell you (it will vary by experiment and your performance), but what I can say is that about 90% of people who did one experiment came back to do another...so people overall must be pretty happy with how much money they're making.
It's not psychology, we're not out to trick you. If we can't tell you something, we'll say that we can't tell you.
