[Note by Jerry S (Sorry OB, I’m invading your entry!)]: I programmed this four years ago; I’d do it slightly differently if I was programming it today – there are a couple of problems with it. However, it is a pretty rigorous experimental design (on the analysis page, there’s a link with technical details about the ‘between-subjects’ and ‘within-subjects’ aspects of the design). And the results, right at the end, are interesting.
