I have to pass this along, even though I'm rolling my eyes as I do it. Here's the study (this is the real title): Elevated ceiling heights reduce the cognitive performance of higher-education students during exams (7 page PDF). If you read the paper, you see the authors acknowledge that it could be because the large rooms are cold, crowded, strange, and harder to cheat in. To me, all this raises the question once again: what is it exactly that we are measuring when we assign and grade exams? Each study like this shows that it's less and less likely to be what they actually know.
