Lefties should be particularly vigilant about the chairs/desks. I've heard stories about them having to take long tests on right-handed flip-up deskettes; a true nightmare. I know the registration forms for my grad comps asked lefties to identify themselves, because almost all of the seats in the auditorium had right-hand deskettes. They brought in as many extra lefty ones as they needed. Is there a similar question on SAT registrations?I have got to find time to write a quick post on working memory.
I believe that the "transmission mechanism" from right-hand desks for left-hand test-takers to reduced performance is working memory blowout.
And see: death by calculator. Death by calculator is a case of working memory blowout.
(The real-world term for working memory blowout problems is cognitive load theory.)
