Exams can be stressful
and everyone looks for a way to make those scores go up.
Wouldn’t it be relieving to know that the answer lies in gum?
是的 小巧 有嚼劲且果味十足的口香糖是你成功的关键
Yes. That small, chewy, fruity piece of gum is your key to success.
那么就坐下来 拿出一条口香糖 然后咀嚼吧
So sit down, grab a stick of gum, and chew.
In the scientific journal Appetite,
a study by professor Onippa shows that
if you chew gum before a test,
your performance will increase slightly as opposed to testing without gum.
224 St. Lawrence University undergraduates were tested
and divided into three groups:
chewing gum before and during the test,
chewing gum for five minutes before the test,
and not chewing gum at all.
Results showed that those who chewed gum before the test scored best,
but their scores leveled out to normal after an average of 20 minutes.
Scores were best right after chewing the gum.
Professor Onippa stated that
chewing gum led to a significant increase in working memory,
and overall, in cognitive function,
while the results were statistically significant.
They were described by Onippa as
showing a difference of two to three words.
It must be noted that chewing gum during the test
did not improve any performance,
as it may have taken away from the function of a brain.
Chewing the gum during the test distracts the brain from the test at hand,
though professor Onippa’s study does show that
gum-chewing improves performance.
There is only speculation and theories as to why.
Initially, some have thought the rise in glucose through the gum
caused better performance,
but this theory has been disproven
as suger-free gum gave the same results.
Mastication induced arousal,
the increase in blood flow to the brain
caused by chewing was another theory,
as it increased awareness.
Another study done by Coventry University discovered that
mint-flavored gum significantly decreases sleepingness in students.
A pupil or graphic sleepness test was given to the students
and showed that they were less exhausted while chewing the gum.
This would give quite an advantage to
those chewing mint gum over those not chewing them at all.
Do you believe that chewing gum helps performance during tests?
Are you willing to give it a go?
