考試前嚼香口膠 易獲高分

【明報專訊】美國一項研究發現，考試前嚼香口膠5分鐘，有助刺激腦部運作以提升表現，考取高分數。
紐約聖羅倫斯大學的心理學研究人員 以80名大學生為測試對象，先向當中一半人派發香口膠（包括含糖及無糖香口膠），請他們在進行測試前或測試期間咀嚼，全體學生隨後需完成一系列認知測試， 包括倒數複述一些隨機數字，解答邏輯問題等。結果發現，在考試前嚼香口膠5分鐘的測試者，平均分數較沒有嚼香口膠者為高，不過在測試途中仍在嚼香口膠者表 現卻較差。
帶領研究的奧尼珀爾（Serge Onyper）稱，研究結果反映大腦處理咀嚼和認知過程有一定共通點。在考試前嚼香口膠，可以咀嚼刺激大腦活動，有助提升認知表現，約可維持20分鐘；而 在考試期間嚼香口膠卻會令大腦注意力分散，未能全力完成主要任務，因而令成績變差。此項研究亦印證了任何身體活動都可提升腦部表現的說法，即使細微的身體 活動亦有效。

"Don't chew gum in class!" How many times have we all heard that while growing up?
In actuality, though, chewing a bit of gum—especially before a big test—may not be such a bad thing.
A new study published in a recent issue of the journal "Appetite" found that students who chewed gum for five minutes before taking a test achieved better marks than those who didn't chew gum.
According to Serge Onyper, the assistant professor of psychology at St. Lawrence University in Canton, N.Y. who conducted the study, the boost in academic performance can be attributed to "mastication-induced arousal," which continues for about the first 20 minutes of the test.
He said that, to reap the benefits, students should chew gum for five minutes before a test—but not during the test.
Other studies conducted in the past have shown that physical activity can indeed give a boost to brain performance, but this study shows that even a very minor physical activity like gum chewing has the ability to do so.
In Montclair, though, it appears that different schools have different policies when it comes to the chewing of gum.
At Renaissance Middle School, for example, Principal Jill Sack said that absolutely no gum chewing is allowed in class.
But at Mount Hebron Middle School, Principal Guy Whitlock said that each "house" sets its own policy, with some teachers allowing gum chewing and others not allowing the practice.
Onyper notes that a possible reason the benefits didn’t continue throughout testing may be due to “a sharing of resources by cognitive and masticatory processes.”
In other words, most people can’t do two things at once: chew gum and successfully take a test.
What do you think? Should gum chewing be allowed in the classroom? Let us know in the comments section below.
