Laughter is a kind of universal body language that’s shared by people of all nationalities, skin colors, cultures and traditions. But did you know that the ability to tell genuine laughter apart from fake laughter also transcends cultures?
笑是一种全球通用的肢体语言,不论国籍、肤色、文化和传统。但你知道吗?其实分辨真假笑声的能力也超越了文化的界限。
Greg Bryant, a professor of communication at the University of California, Los Angeles, US, published a study in Psychological Science in late July in which he found that people are able to identify real laughter through slight variations in sound.
去年7月下旬,美国加州大学洛杉矶分校的传播学教授格雷格·布莱恩特在《心理科学》杂志上发表了一项研究,他发现人们能够通过声音的细微变化辨别出真笑。
In the study, 884 people from 21 countries were asked to listen to random recordings of laughter. Some of the recordings were made up of spontaneous laughs, while others were made by people who were asked to laugh on command.
在这项研究中,来自21个国家的884人随机听取了一些笑声的录音片段。有些录音里是自发的笑声,而有的则是人们被要求录下的。
The study showed that people around the world have the ability to pick out real laughter, although their abilities vary from country to country. Residents of the Samoan Islands, an island chain in the central South Pacific, were particularly good at it, correctly identifying real laughter 56 percent of the time.
