研究:左撇子更易發怒
Life holds many frustrations for left-handed people – from the everyday items designed for right-handers to folklore saying they are in league with the devil.
So perhaps it is the result of dealing with such adversity 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 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 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 professor at Merrimack College in Massachusetts, found that the halves of the brain in those who are lefties or ambidextrous are more interlinked.
This makes them more moody, research published in the Journal of Nervous and Mental Disease found.
Previous studies have shown that 'lefties' are more prone 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 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 , 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.'
對於左撇子來說，生活中有許多令人懊惱的事情，日常物件多是爲右撇子設計的，民間傳說還說他們是魔鬼的同夥。
研究者稱，也許是因爲總是身處這樣的逆境，他們比平常人更容易發怒。
研究者發現，左撇子大腦的兩個半球之間交流得更多，因此和產生消極情緒的部位的互動也更多。
不管是開罐器、園藝工具，還是小刀、剪子，每樣東西的設計通常都沒有爲左撇子考慮。
過去，世世代代的左撇子小孩在學校裏被迫用右手寫字。數個世紀以來，他們一直承受着“左撇子是邪惡的或者會帶來厄運”的污名。
人們還經常把左撇子和笨拙聯繫起來。
麻省莫瑞麥克學院的心理學教授露絲•普若普爾是這一研究的領頭人。該研究發現左撇子或雙手通用的人的大腦兩個半球的聯繫更緊密。
研究發現，這讓他們更加情緒化。這一研究發表在《神經病與精神病雜誌》上。
先前的研究顯示，左撇子更容易產生消極情緒。
世界上許多領袖和明星都是左撇子，他們當中有些人是出了名的脾氣暴。
其中一位脾氣壞得出名的左撇子是鮑勃•吉爾道夫，他能有今天的名氣，一部分要歸功於他在“拯救生命”演唱會的電視轉播過程中破口大罵。
另外一位是網球界的傳奇人物約翰•麥肯羅，他的壞脾氣和他的成功一樣出名。
當今的世界領導人當中，貝拉克•奧巴馬和戴維•卡梅倫都是左撇子。
不過，銷售左撇子專用商品的網站所有者勞倫•米爾森姆說：“左撇子會接受這些不順，並不會抱怨那麼多。
“我們應對的是爲右撇子設計的世界。”
