研究:左撇子更易发怒
Life holds many frustrations(挫折) for left-handed people – from the everyday items designed for right-handers to folklore（民间传说） saying they are in league with the devil.
So perhaps it is the result of dealing 1 with such adversity（逆境） that, according to researchers, they are angrier than the average person.
Researchers found that among lefties, the two hemispheres of the brain communicate more with each other so have more interaction with the parts which produce negative（消极的） emotions.
Everything from can openers to garden tools to knives and scissors tends to be designed without taking them into consideration.
Many generations of left-handed schoolchildren were forced to write with their right hand. They have endured centuries of stigma 2 that says being left-handed is evil or bad luck.
And they are often associated with clumsiness and awkwardness.
The study, led by Ruth Propper, a psychology 3 professor at Merrimack College in Massachusetts, found that the halves of the brain in those who are lefties or ambidextrous 4 are more interlinked.
This makes them more moody 5, research published in the Journal of Nervous and Mental Disease found.
Previous studies have shown that 'lefties' are more prone 6 to negative emotions.
Many of the world's leaders and stars are left-handed, with some known for being hot-tempered.
One famously grumpy 'leftie' is Bob Geldof, who achieved fame thanks in part to swearing during TV coverage 7 of Live Aid.
Another is tennis legend John McEnroe, who is as famous for his tantrums as his successes.
Current world leaders who are left-handed include Barack Obama and David Cameron.
But Lauren Milsom, owner of Anythinglefthanded.com, which sells goods for left-handed people, said: 'Left-handed people just get on with it and do not complain that much.
'We just deal with a world designed for right-handers.'（本文由在线英语听力室整理编辑）
