Today we will ask a few questions about the "files" you saw yesterday.
You will need to enter the same anonymous USERNAME that you picked yesterday.
The questions should take roughly 5 minutes.
Your performance is anonymous, but concentrate and try to do well.
If you are seriously interrupted or distracted or
do not wish to continue for any reason,
just hit the "Quit" button. You can revisit the web page later
if you choose.
If the distraction is small (several seconds) don't worry
and just continue on.
Please do not run the experiment to completion more than once.
