大脑对盛行的回想
你能说出多少位美国总统的姓名？研讨人员发现，大部分人能够记住榜首和第二任总统，华盛顿和亚当斯；以及最近两任，奥巴马和小布什；可是在这之间的，一个也没被记住。
纽约大学（New York University）的帕斯卡尔·瓦利施（Pascal Wallisch）研讨的范畴被称作神经数据科学，也便是处理随同神经活动研讨而呈现的很多数据。他表明，咱们回想总统的进程遭到两种要素的分配：首因效应（primacy effect）——最早呈现的人，和近因效应（recency effect）——最近呈现的人。
他和搭档想了解，这种文明回想形式是否也适用于盛行音乐的回想。“是否存在一种文明视界，或许事情视界，一旦跳过这一边界，人们的常识就会降为零？”
因而，他的团队询问了 600 多名受试者，其间大部分人归于千禧一代，他们试听了从 1940 年至 2015 年金曲榜上排名榜首的歌曲片段，然后被要求讲出是否听过这些歌。
成果显现，受试者简直认不出四五十时代的曲子（比方"Chattanooga Choo Choo"、"Cold Cold Heart"、"Sleepwalk"）。首因效应能够解说总统问题，可是关于盛行歌曲就说不通了；近因效应依然适用，由于近两年的新歌，比方"Happy"，就比此前的歌曲（"Smooth"、"Baby Boy"、"Drop It Like It's Hot"）更让他们耳熟。
但时刻再往前推，近因效应也不适用了，由于跟着时刻从 90 时代，80 时代，70 时代到 60 时代的逐步拉远，受试者对歌曲的熟识度并没有随之下降，反而维持着安稳的辨认水平……[检查全文]
Our Brains Really Remember Some Pop Music
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 science—dealing 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 effect—who came first—and the recency effect—who'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 volunteers—most of them millennials—to listen to snippets ofBillboardnumber>
Turns out the volunteers barely recognized tunes from the `40s and `50s…. Suggesting the primacy effect holds for presidents, but not pop music. But the recency effect did seem to hold true—because songs released in the last few years were more recognized than those released in the aughts.
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…[full transcript]
