Worry about taking a math test makes you do worse

Worrying about how you'll perform on a math test may actually contribute to a lower test score, U.S. researchers said on Saturday.

Math anxiety -- feelings of dread and fear and avoiding math -- can sap the brain's limited amount of working capacity, a resource needed to compute difficult math problems, said Mark Ashcroft, a psychologist at the University of Nevada Los Vegas who studies the problem.

"It turns out that math anxiety occupies a person's working memory," said Ashcroft, who spoke on a panel at the annual meeting of the American Association for the Advancement of Science in San Francisco.

Ashcroft said while easy math tasks such as addition require only a small fraction of a person's working memory, harder computations require much more. Worrying about math takes up a large chunk of a person's working memory stores as well, spelling disaster for the anxious student who is taking a high-stakes test.

Stress about how one does on tests like college entrance exams can make even good math students choke. "All of a sudden they start looking for the short cuts," said University of Chicago researcher Sian Beilock. Article here.
