Whew, Brad, just reading this and letting my brain absorb it is a real teaser! Thanks for sharing and also for giving me a real stumper!
Joanna, as you saturate yourself in the research the terms come forth easily. But I also try to make this user friendly by showing strategies that benefit you. That's the part I enjoy most.
Hi Robyn,
The question is, "Will the other computer tell me door A leads to death?" Assume Door A does lead to death. The truthful computer will answer "no," because the lying computer, if asked that question, would lie and say "no". However, the lying computer will also answer "no", because the truthful computer would answer "yes".
Now, let's assume Door A leads to life. In that case, if the same question is asked, "Will the other computer tell me door A leads to death?" the truthful computer will answer "yes", and the lying computer will also answer "yes".
So, if the man gets "no" for an answer, he escapes through Door B. If he gets "yes" for an answer, he escapes through Door A.
Whew! I hope I got that right.
"One of the reasons is that they're completely opposite of past associations stored in the basal ganglia!"
It must be so great to be able to write with sentences like that - with total confidence!
Joanna
Cheh, please do come back with your brain teasers! We'd love to see what you have!
Hi Bob, these really do tease our brain. One of the reasons is that they're completely opposite of past associations stored in the basal ganglia!
Brad, I really worked on your brain teaser and I could not develop a question that worked. So please tell us the right question!!!!
Hello Robyn, we have a good collection of teasers...
These are 10 of our most popular (which, of course, includes Stroop...but check the others!)

I really liked this an as example of how we don't usually see what's really there, but rather we associate what we think we see with what we've already experienced.
OMG, I had fun with this challenge!lol Thanks for sharing robyn!
I know I got some brainteaser somewhere,let me dig & come back
OK, Robyn, I'm takin' the challenge!
Blue. Pink. Orange. Pink. Grey - no, Orange. Red, er, pink, um - augh!!!! (sound of brain exploding)
I hope it makes the time pass quickly.
Hey Brad this is fun... Hmmm... I'll think on this one while I'm driving today...
Hi Robyn, Here's a brain teaser--kind of old but one I've always thought is quite elegant.
A man is trapped in a room with two doors, A and B. He knows that one door leads to life and the other door leads to death. There are two computers in the room. One computer always tells the truth. The other computer always lies.
The man can ask one computer one question. What question does he ask to determine which door leads to life?
