I actually didn't mean to implicate stress, although it is of course also a factor for some people. But even in non-stressful situations, frequent breaks from cognitive load are simply a necessity for me. I think it's because my brain is more like a sprinter than a long distance runner, and the latter is probably better suited to typical tests. I can start getting real sloppy after even 15 minutes of intense mental focus, even if I know the material well. But of course sprinting has its benefits in other situations, so it all balances out.
