动物比人更早学会笑:呼吸系统作用

  There is ample evidence that many other mammals make play sounds, including tickle-induced panting, which resembles human laughter. Indeed, animals are capable of many emotional feelings, just like humans, some scientists say.

  有很多证据可以表明,其他一些哺乳动物也可以发出类似笑的声音,其中包括很类似于人类笑声的由挠痒痒引起的喘息声。一些科学家说,事实上,动物和人类一样是具有多种情感和情绪的。

  "The recognition by neuroscientists that the brain mechanisms underlying pain, pleasure, fear, and lust are the same in humans and other mammals underscores our similarity to other species and is extremely important," said Tecumseh Fitch, a psychology lecturer at the University of St. Andrews in Scotland.

  苏格兰圣·安德鲁斯大学的心理学讲师菲奇表示:“神经科学家公认的,人类和其它哺乳动物间支撑痛苦、压力、恐惧及性的大脑机制都是相同的这一理论强调了人类与其它物种的相似之处,而这一点是非常重要的。”

  In a 2003 study Panksepp and Bowling Green State University neurobiologist Jeff Burgdorf demonstrated that if rats are tickled in a playful way, they readily chirp. Rats that were tickled bonded with the researchers and became rapidly conditioned to seek tickles. Understanding the chirping of the rats may help scientists better understand human laughter.

  早在2003年的一项研究中,潘克塞普和保令·格林州立大学的神经生物学家杰夫·伯格多弗就曾证明,如果人们以一种十分有趣的方式胳肢老鼠,它们就会发出一种唧喳的声音。而弄清老鼠的这种叫声,则可能会帮助科学家们更好地了解人类笑的历史。

  Robert Provine, a psychology professor at the University of Maryland in Baltimore, agrees there is an evolutionary continuity of laughter. Its origin is in tickling and rough-and-tumble play, he says.

  美国马里兰大学的心理学教授罗伯特·布鲁文赞同笑也具有进化连续性的这一说法。他说,笑的起源来自于挠痒痒以及杂乱无章的游戏。

  Provine and other scientists have studied chimpanzees and found a link between their laughter-like noises and human laughter. "Laughter is literally the sound of play, with the primal 'pant-pant'--the labored breathing of physical play--becoming the human 'ha-ha,'" Provine said.

  布鲁文教授和其他一些科学家还对黑猩猩进行了相关的研究,他们发现黑猩猩的笑(声音类似于噪音)与人类的笑存在着某种联系。他说:“确切地讲,笑是一种游戏的声音,从最初的‘喘气的呼呼声’(吃力的呼吸声)发展到人类的‘哈哈’笑的声音。”

  By studying the transition between the panting of chimps and the human ha-ha, scientists discovered that breath control is the key to the emergence of both human laughter and speech.

  通过研究从大猩猩喘气的呼呼声到人类“哈哈”的笑声两者之间的转化,科学家发现,呼吸控制是人类语音和笑声出现的关键所在。
