  • This is Scientific American — 60-Second Science. I'm Christopher Intagliata.
  • 这里是科学美国人——60秒科学。我是克里斯托弗·因塔利亚塔。
  • How many U.S. presidents can you name?
  • 你能说出几位美国总统的名字?
  • For most people, researchers have found "the first couple are remembered, like Washington, Adams.
  • 研究人员发现,大多数人“记住了前几位,比如华盛顿和亚当斯。
  • And the last couple. Obama, Bush, people like that. But then nothing in between."
  • 还能记住最近几位总统。比如奥巴马、布什等。但中间的总统名字却不记得了。”
  • New York University's Pascal Wallisch studies what's called neural data science—
  • 纽约大学的帕斯卡尔·瓦里斯赫研究“神经数据科学”——
  • dealing with the huge amounts of data that come with studying neuronal activity.
  • 即处理研究神经元活动时获得的大量数据。
  • And he says our recall of presidents is governed by two factors:
  • 他表示,我们对总统的记忆由两个因素控制:
  • what's known as the primacy effect—who came first—and the recency effect—who's been around lately.
  • 其一是首因效应,即谁先出现,其二是近因效应,即谁最近出现。
  • He and his colleagues wanted to see if the same type of cultural memory pattern would hold true for pop music.
  • 他和同事想知道,同样的文化记忆模式是否适用于流行音乐。
  • "The question was, is there a cultural horizon, or event horizon, at which point knowledge drops to zero?"
  • “问题是,是否存在一种文化视野或事件视野,会出现知识降为零的情况?”
  • So his team asked more than 600 volunteers—most of them millennials—
  • 因此,他的团队征集了600多名志愿者——其中多数人是千禧一代——
  • to listen to snippets of Billboard number one hits from 1940 to 2015, and to say whether they'd heard the songs.
  • 让他们听1040年至2015年间公告牌冠军热门单曲的片段,并让他们回答是否听过这些歌曲。
  • Turns out the volunteers barely recognized tunes from the '40s and '50s...
  • 结果发现,志愿者几乎识别不出上世纪40年代和50年代的歌曲。
  • Suggesting the primacy effect holds for presidents, but not pop music.
  • 这表明首因效应适用于记总统名字,但不适用于记流行歌曲。
  • But the recency effect did seem to hold true—
  • 但近因效应似乎在此适用,
  • because songs released in the last few years were more recognized than those released in the aughts.
  • 因为最近几年发行的歌曲的被识别程度要高于之前发行的歌曲。
  • But then the recency effect stalled.
  • 但之后,近因效应也止步不前了。
  • Because rather than continuing to drop in recognition back through the '90s, '80s, '70s and '60s,
  • 因为虽然上世纪90、80、70和60年代的歌曲辨识度持续下降,
  • songs in that 40-year period saw a steady plateau of recognition among the listeners.
  • 但听者对40年代歌曲的认知度却趋于稳定。
  • Within which was noticeable variability in song recognition, despite the fact these were all number one hits in their day.
  • 尽管这些歌曲都是当年的冠军热门单曲,但是识别度存在明显差异。
  • For example, some tunes were almost universally recognized whereas other number ones barely registered.
  • 举例来说,一些歌曲几乎家喻户晓,但其他冠军歌曲却几乎未被记住。
  • The study and full song list is in the journal PLOS ONE.
  • 这项研究和完整的歌单发表在《公共科学图书馆·综合》期刊上。
  • It's not clear why the study subjects remembered what they did—
  • 至于为什么研究对象记得他们做过的事情,目前尚不得而知——
  • whether music from the late 20th century had something special about it, or if maybe over-the-air radio DJs influenced the result.
  • 是因为上世纪末的音乐有特别之处,还是无线电台主持人影响了结果?
  • "These are great questions. And I think they're probably best addressed by doing this in another 30 years when radio's been gone.
  • “这些是大问题。我认为可能在30年后广播消失以后,再来解决这些问题更好。
  • And then we'll see what's stable and not stable about this."
  • 那时我们就会知道哪些是稳定因素,哪些是不稳定因素。”
  • As for Wallisch? "I listen to the softest pop you can imagine."
  • 那瓦里斯赫听什么歌呢?“我听的是你们能想象到的最柔和的流行音乐。
  • And, an even more obscure genre: "I like to listen to my data."
  • ”还有一种更晦涩难懂的音乐类型:“我喜欢听我的数据。”
  • Digital music is just numbers, after all, and with certain programs you can analyze your data by listening to it.
  • 毕竟数字音乐只是数字,而利用某些程序,你可以通过听来分析你的数据。
  • Just don't count on all those numbers turning into number one.
  • 不过不要指望这些数字都能变成第一就好。
  • Thanks for listening for Scientific American — 60-Second Science. I'm Christopher Intagliata.

This is Scientific American — 60-Second Science. I'm Christopher Intagliata.
How many U.S. presidents can you name? For most people, researchers have found "the first couple are remembered, Washington, Adams. And the last couple. Obama, Bush, people like that. But then nothing in between."
New York University's Pascal Wallisch studies what's called neural data sciencedealing with the huge amounts of data that come with studying neuronal activity. And he says our recall of presidents is governed by two factors: what's known as the primacy effectwho came firstand the recency effectwho's been around lately.
He and his colleagues wanted to see if the same type of cultural memory pattern would hold true for pop music. "The question was, is there a cultural horizon, or event horizon, at which point knowledge drops to zero?"
So his team asked more than 600 volunteersmost of them millennialsto listen to snippets of Billboard number one hits from 1940 to 2015, and to say whether they'd heard the songs.
Turns out the volunteers barely recognized tunes from the '40s and '50s...(montage: "Chattanooga Choo Choo," "Cold Cold Heart," "Sleepwalk"). Suggesting the primacy effect holds for presidents, but not pop music. But the recency effect did seem to hold truebecause songs released in the last few years <"Happy"> were more recognized than those released in the aughts. ("Smooth," "Baby Boy," "Drop It Like It's Hot")

But then the recency effect stalled. Because rather than continuing to drop in recognition back through the '90s, '80s, '70s and '60s, songs in that 40-year period saw a steady plateau of recognition among the listeners. Within which was noticeable variability in song recognition, despite the fact these were all number one hits in their day.
For example, some tunes were almost universally recognized (montage: "When a Man Loves a Woman," "The Loco-Motion," "Baby Come Back") whereas other number ones (montage: "Roll with it Baby," "I'm Sorry") barely registered. The study and full song list is in the journal PLOS ONE.
It's not clear why the study subjects remembered what they didwhether music from the late 20th century had something special about it, or if maybe over-the-air radio DJs influenced the result. "These are great questions. And I think they're probably best addressed by doing this in another 30 years when radio's been gone. And then we'll see what's stable and not stable about this."
As for Wallisch? "I listen to the softest pop you can imagine." And, an even more obscure genre: "I like to listen to my data." (data music sample) Digital music is just numbers, after all, and with certain programs you can analyze your data by listening to it. Just don't count on all those numbers turning into number one.
