CANTON, N.Y., Nov. 30 (UPI) -- Students who chewed gum for 5 minutes before taking a test did better on the test than students who did not chew gum before the test, U.S. researchers said.
Serge Onyper, an assistant professor at St. Lawrence University in Canton, N.Y., said "mastication-induced arousal" is credited for the testing score boost, which lasted for about the first 20 minutes of testing.
