This is Scientific American 60-Second Science. I'm Cynthia Graber. Got a minute?

隐藏原文=

Language can take many forms,spoken, written, even gesticulated, as with American Sign Language.

点击显示原文

隐藏原文=

Regardless of the language form, the left hemisphere of the brain dominates the information processing.

点击显示原文

隐藏原文=

But the right hemisphere plays a greater role in processing acoustics, pitch and melodies.

点击显示原文

隐藏原文=

Which is why researchers were curious about how the brain processes whistled Turkish.

点击显示原文

隐藏原文=

Yes, that's Turkish, but being whistled rather than spoken.

点击显示原文

隐藏原文=

Before the advent of telephones, mountain communities separated by valleys modified the spoken language into sounds that can be heard up to a couple of kilometers away.

点击显示原文

隐藏原文=

For instance means, "Do you have fresh bread?"

点击显示原文

隐藏原文=

And translates to: "Who won the game?"

点击显示原文

隐藏原文=

One member of the research team said he first could not recognize the whistles as Turkish, but was able to pick out words within a week.

点击显示原文

隐藏原文=

So what's going on in the brains that hear and understand these sounds?

点击显示原文

隐藏原文=

When researchers played spoken Turkish syllables through headphones, the subjects' right ears did the most work.

点击显示原文

隐藏原文=

Again, the right ear links to the brain's left hemisphere, the usual primary site for spoken information processing.

点击显示原文

隐藏原文=

But when whistled Turkish syllables were played into the headphones, the subjects' left and right ears shared the task equally, indicating that the two brain hemispheres are both heavily involved in working out the whistles.

点击显示原文

隐藏原文=

The findings are in the journal Current Biology.

点击显示原文

隐藏原文=

The researchers write that "a natural but acoustically different language can create a radical change in the organization dynamics of language asymmetries."

点击显示原文

隐藏原文=

In other words, the brain will adjust quickly to make sense of incoming information.

点击显示原文

隐藏原文=

Oh, and that first whistle you heard?

点击显示原文

隐藏原文=

It means "I speak whistled Turkish."

点击显示原文

隐藏原文=

Thanks for the minute, for Scientific American 60-Second Science. I'm Cynthia Graber.
