Cracking Up With A Friend Or Politely Chuckling With A Stranger? Your Laughter Reveals It All!
你的笑声出卖了一切
Laughter, be it a loud guffaw or a well-mannered giggle, is a universal way to express joy. But as it turns out, your chuckle reveals a lot more than the fact that you are happy. It enables listeners, even those that cannot observe you, instantly realize if you are having a good time with a close friend or laughing politely with a complete stranger.
无论是哈哈大笑还是抿嘴轻笑，“笑”是用来表达“快乐”的通用语言。事实上，“笑”传达的意思远比“开心”要多得多。你是与密友玩的很开心还是仅仅是对陌生人表示礼貌，这些听的人（甚至是局外人）都能从你的笑声中判断出来。
At least that is the conclusion reached by a team of scientists led by Greg Bryant, an Associate Professor of Communication Studies at the University of California, Los Angeles. The researchers began by requesting collaborators from across the globe to send them audio clips of people laughing. The 48 tapes they received ranged from recent recordings of laughter between two college friends to ones from conversations that occurred a decade ago. The clips also had all possible combinations — Interactions between friends, strangers, all-male groups, all-female groups, as well as a mix of both genders.
Greg Bryant（洛杉矶加州大学交流研究方向的副教授）带头的科学小组研究对此进行过专项研究。起初，他们让来自世界各地的参与者发给他们笑声录音。收到的48份录音中，有近期录制两个大学生的笑声，也有来自十年前一段对话的笑声。此外，里面还包括朋友之间、陌生人之间、全部是男性、全部是女性以及男女混合交谈中发出的笑声。
The team then played the short recordings, each lasting less than a second, to 966 people spread across 24 different cultures around the world. The listeners ranged from people residing in remote areas to those living in some of the world’s most modern cities. To the team’s astonishment, despite the cultural and regional differences, the listeners were able to identify the difference in laughter between friends and strangers, 61% of the time.
随后，小组把这些录音（不小于一分钟），播放给966个来自24种不同文化的人。这些人有的来自偏远地区，有的来自世界最繁华的都市。让小组震惊的是，抛开文化和地域差别，试听者都能够正确判断笑声来自朋友还是陌生人，正确率高达61%。
The scientists, who published their findings in the Scientific Journal, Proceedings of the National Academy of Sciences on March 9, 2016, say that the accuracy was even higher when it came to recordings of only women laughing.
他们在2016年3月9日的《美国科学院论文集》中发表了此次研究结果。同时，他们还表示，对女性笑声判断的正确率比这个研究结果的平均值还要高。
The researchers speculate that this is probably because women are more transparent in expressing their feelings than men.
研究者进一步解释，这可能是因为女性比男性更容易表达自己的真实情感。
