Smart People Choke Under PressureBy Bjorn Carey

SourcePeople perceived as the most likely to succeed might also be the most likely to crumble under pressure.A new study finds that individuals with high working-memory capacity, which normally allows them to excel, crack under pressure and do worse on simple exams than when allowed to work with no constraints. Those with less capacity score low, too, but they tend not to be affected by pressure.
"The pressure causes verbal worries, like ‘Oh no, I can’t screw up,’" said Sian Beilock, assistant professor of psychology at Miami University of Ohio. "These thoughts reside in the working memory." And that takes up space that would otherwise be pondering the task at hand.
"When they begin to worry, then they’re in trouble," Beilock told LiveScience. "People with lower working-memory capacities are not using that capacity to begin with, so they’re not affected by pressure."
The findings are detailed this week’s issue of Psychological Science.
Working memory, also known as short-term memory, holds information that is relevant to performance and ensures task focus. It’s what allows us to remember and retrieve information from an early step of a long task, such as long-division math.
"In these math problems students have to perform subtraction and division, and if you’re trying to hold information in your memory and you start worrying about performance, then you can’t use your entire mental capacity to do the math," Beilock explained.
The study analyzed 93 undergraduate students from Michigan State University to determine their working-memory capacities. The students were divided into two groups, a high working-memory group (HWM) and a low working-memory group (LWM). Each person was given a 24-problem math test in a low-pressure environment. The HWM group did substantially better.
Then the two groups were given the same test, but were told that they were part of a "team effort" and an improved score would earn the team a cash reward. They were also told their performance was being evaluated by math professors.
Under this higher, real world pressure situation, the HWM group’s score dropped to that of the LWM group, which was not affected by the increased pressure.
Since working memory is known to predict many higher-level brain functions, the research calls into question the ability of high-pressure tests such as the SAT, GRE, LSAT, and MCAT to accurately gauge who will succeed in future academic endeavors.

SourceWhen I was in high school, I admired the "tough" teachers, who gave hard exams and had "old fashioned standards", three of my math teachers were like that. They were proud that they routinely gave homework problems that even engineer parents couldn't solve (with the limited methods the kids had been taught).
I left high school early, and got an A in Calculus at Harvard, where the course was rather loosely structured: lecture attendance was optional; you took exams when you felt like it; and there was a pool of fresh exams, so you could take a different exam on each topic (up to twice) if you later gained a deeper insight into a concept, emphasized the wrong concepts in your self-study or simply blew a test.
My high school calc teacher was rather offended by my departure (she'd openly said I'd never amount to anything) and when I mentioned my Harvard "A" to the department chairman on a return visit, she challenged me to take HER final [She'd apparently done this with other students who'd left early, and none had passed.) I passed, but I didn't do particularly well. (Much as the engineering parents might've done, I suppose)
However, I stayed in touch with several of my fellow Honors Math students who had aced her course and went to college in Cambridge. I think they'd all agree that I remained better and more creative in basic calculus than them -- even the ones who went to MIT (I'm not dissing MIT; I've long been associated with that school)
Though I have always been a big fan of alternative approaches to education, it was over ten years and two doctorates later before I realized that these "tough, old-school" teachers hadn't been teaching very well at all. Their "tough" problems really tested how well you retained the trickier examples from of their homework problems.
Though they were quite good at instilling the fundamentals of Algebra 2, Calculus, etc., they hadn't really given their students much skill at "free-form" math. Sadly, in the real world, all math problems are free form: creativity and insight are invaluable, but limiting yourself to specific chosen techniques is almost always a meaningless exercise.
It really saddens me, because I still have a profound respect for "old school" teachers. The problem is: just being "tough" and "old school" isn't enough, and I think many such dedicated teachers would change their methods somewhat and become even more outstanding teachers, if only someone could make them fully understand this one weakness in their teaching, but instead they believe that their daily experience reaffirms the validity of their methods.
I was fortunate to have one teacher, in two different high school courses, who had been a former engineer and valued creative solutions. He also became our Math League coach in those years, and suddenly we went from the bottom of our local league to the top of the state [I still grin when I remember walking through the cafeteria "staging area" for the meets, and hearing the former top schools asking "who are these guys] Our success wasn't just due to his teaching -we barely did any prep, compared to the Powerhouses in our league- but was equally due to his encouragement of creative thinkers, including freshmen (like myself and a coupple of others who I fully admit were more talented at math than I was). Before his tenure, only the Seniors with the best grades (and a few exceptional Juniors) were encouraged to join.
That last point is important: the juniors/seniors on the team when I was a freshman were good, and certainly knew more math than we underclassmen did, make no mistake, but we had, nonetheless, been near the bottom of our league, so I can only guess that they hadn't done well with problems for which they hadn't been specifically prepped, and our math league categories leaned heavily toward "free form" problems, as opposed to "solve this equation".
Suddenly I'm flooded with repressed high school memories. Man, what a waste of life tht would've been, If it hadn't been for the girls [who says geeks can't date like demons?]. Just for the record, though, this isn't high school bitterness. I'm a 40-something, and the past two decades have offered many fresher things to be bitter about!
