I dunno. That sort of defeats the objective of assessing that person's natural reaction to a little interview pressure. It's not water boarding, it's a simple programming or logic puzzle that requires most people to think.
People (on average) are nervous, anxious, etc during an interview. I don't really care how they "naturally" react in that situation as THAT situation isn't day-to-day (at least not in the software companies I've spent my time) so I'm almost don't really care about that.
I really just care about how well they problem solve, not problem solve in a fox-hole with bullets flying over their head.
