We each take the WinSCAT on a laptop, under the supervision of various Wyle psychologists.  Both Astronauts and Flight Analogs take this test repeatedly through screening and then again through training -- or in my case, testing. Astronauts also take it while on their missions to measure any changes, and again when they get home. To mimic this, I'll be taking it a few more times over the course of bedrest, and again when I rise in late October.
The first run-through feels clumsy, because you must read screens of instructions as you go.  Screens flash by, and you have to click the right mouse button for some answers, left mouse button for others as it moves swiftly through mathematical problems, "code substitution," spatial pattern comparisons and memory puzzles.  Accuracy MATTERS; click response time in the correct places and overall testing time are also factors.  
I can't find anything on the web that shows the nature of the tests themselves, though I did find a picture of the introductory screen, and as part of an earlier campaign, a public domain description on the NASA Technical Reports Server.  I also found an interesting slideshow at the Military Operational Medicine Research Program (MOMRP) in the NASA: Human Factors Requirements section, presented by Dr. Edna Fiedler.

To the collective shock of anyone who knows me, I have consistently gotten good scores on the math portions. I thought I was hallucinating too. Definitely would have preferred essay questions ;)    Spatial patterns, I always ace those, and I have to say, I'm far more pleased with performance on this than the  "Hey, Let's See How Many Pull-Ups You Can Do" test, that's for sure.  
(Fair warning footnote to my friends: If some rogue drill sergeant takes you hostage one day and calls me to say, "Do twenty pull-ups or your friend gets it!" Yeah, you're toast.)
We get results immediately, so there's no mystery on this one, and I've improved both scores and response times with each round, but I was disappointed it wasn't rising faster.  When I wanted SPECIFICS around the fourth go, the conducting psychologist grinned and mentioned I had such an "astronaut mentality."  I asked what she meant by that and she said it was clear I was pushing to do better each time, but more interested in beating my OWN score than inquiring about anyone else's. Astronauts are like that, she said, and they are always their own worst critics, even when they perform extremely well.
Judging by the personalities in this joint, I know I am not alone -- we just want to always do BETTER.  I don't think anyone cares if we "beat" anyone, and I wouldn't expect anyone else's score to be disclosed anyway.  I just get peeved when I don't nail it perfectly, and I like to see tallies that say "100%" at the end.
At the time of this writing (Day 40 overall, Day 27 of bed rest), I've had seven WinSCATs, and have five to go.  The first were "baseline" scores, the ones during bedrest are to ensure there is no significant cognitive decline, and the final two will be after I get out of bed.
