General Issue: Redoing tasks

[bissettp]

Why are we letting them redo tasks? In the initial battery instructions, it's unclear under what circumstances subjects should be redoing a task. I don't think we want them to redo (for example) if they think they have caught onto the task and would like to do it again now that they're better. I think we should consider either: (1) not letting subjects redo tasks, or (2) be more explicit that we only want them to redo tasks under a specific set of circumstances (e.g., they were forced away from the computer by some pressing real-world demand)

I think the circumstances are something along the lines of, something unexpected happens and they are forced to run away from the computer, or have some other belief that a task is not properly done.

I haven't included instructions at all yet so it is definitely unclear. We left it in for the reasons vsoch mentioned. I didn't consider people redoing tasks just to do better. Hmmm...

Given a 10 hour battery, I think people would just want to finish, vs. doing some annoying task over just to slightly improve performance. The only incentive to totally redo (I think) would be if the performance was SO bad (aka left keyboard) that they risk not getting credit, period, and that was the reason we made the redo button to begin with.
