It's not really homework, since this is what I do for a living, but if you are willing to spend 5 minutes, please visit my online visual cognition laboratory:
http://vacognition.wjh.harvard.edu/participate.html
I put up new experiments fairly regularly, so if you feel like being particularly helpful -- or if you just find it interesting -- you can bookmark the page or join the mailing list. I have a Google Groups mailing list I use *ONLY* to announce new experiments or results from old experiments. You won't get spammed, I promise.
Thank you all very much,
