I also say it's a test of memory and concentration. And throughout my performance, I have them look at their card 2 or three times: first at the start, then after the "superspeed" change part, then after the "slow motion" change part. After complimenting their good memory and concentration, I say I'm testing them now. So, words to the effect of: "Okay, just a simple yes or no is what I want from you -- WITHOUT LOOKING, do you think you can remember which card you have?"
I have not yet had anyone turn the cards over on me before I was ready. And besides, the way I set it up, my audience is not expecting the cards to change -- I have them thinking that they'll get the cards wrong.
