And yet, people have been chewing gum for thousands of years, ever since the ancient Greeks began popping wads of mastic tree resin in their mouth to sweeten the breath. Socrates probably chewed gum. It turns out there's an excellent rationale for this long-standing cultural habit: Gum is an effective booster of mental performance, conferring all sorts of benefits without any side effects. The latest investigation of gum chewing comes from a team of psychologists at St.
Lawrence University. The experiment went like this: students were given a battery of demanding cognitive tasks, such as repeating random numbers backward and solving difficult logic puzzles. Half of the subjects chewed gum sugar-free and sugar-added while the other half were given nothing. Here's where things get peculiar: Those randomly assigned to the gum-chewing condition significantly outperformed those in the control condition on five out of six tests.
The one exception was verbal fluency, in which subjects were asked to name as many words as possible from a given category, such as "animals. While previous studies achieved similar results -- chewing gum is often a better test aid than caffeine -- this latest research investigated the time course of the gum advantage.
It turns out to be rather short lived, as gum chewers only showed an increase in performance during the first 20 minutes of testing. After that, they performed identically to non-chewers.
