blinking is important

So, I went to the experiment at 8:30 this morning. The task was to draw a line in the specified circles on the computer screen using the mouse-like pen (I don't know the correct name for this device). The experiment lasts for four days, and the first three days are practice sessions. Each session lasts for about an hour. Depending on how well I do on the fourth day on this task, I can get paid up to $200. I don't know if I will still get paid even if I did horrible on the task. If I did really bad on the fourth day and didn't get paid at all, that would be such a waste of time. This fear motivated me to put lots of effort into this task this morning even though the task itself was sooooooooooo boring. And, while I was in the session, I forgot to blink, and my contacts dried up on my eyes! As a (future) psychologist, I think that telling participants that the payment depends on their performance is their strategy to motivate them. (indeed, this strategy is working for me!) Otherwise, nobody will put any effort into this stupid task. anyway, I hope I will get paid something on Thursday.
