Scientists studying emotions have found that basic emotions like amusement, anger, fear, and sadness are common among all cultures. And people from different cultures, whether they’re modern Americans or pre modern aborigines, recognize sound cues like laughter to signify specific emotions. In other words, all people, everywhere around the world, laugh when they’re amused. And cry when they’re sad. And make scared sounds when they’re scared. Even some non human animals, like chimps, have a type of laughter. So we may not all find the same things funny or scary or sad. But we all feel and express these emotions.

研究情绪的科学家们发现在所有文化普通存在着四种基本情绪,比如：娱乐，愤怒，恐惧和悲伤。来自不同文化背景的人，无论他们是现代美国人或前现代原住民，识别诸如笑声这样的声音提示来表示特殊的情绪。换句话说，全世界各地的人，他们被逗乐时会笑。伤心时会哭。害怕时会发出令人惊恐的声音。甚至一些非人类的动物，如黑猩猩，有某种类型的笑声。因此，看待同样的事情，不是所有人都肝胆有趣，吓人或是悲桑。但我们都能感觉并表达这些情绪。
