Is brain rot real? Researchers warn of emerging risks tied to short-form video

From: NBC NEWS

With short-form video now dominant on social media, researchers are racing to understand how the highly engaging, algorithm-driven format may be reshaping the brain.

From TikTok to Instagram Reels and YouTube Shorts, short-form video content has become a cornerstone of just about every online platform, including LinkedIn and even Substack. But increasingly, studies are finding associations between heavy consumption of short-form video and challenges with focus and self-control.

The research, though still early, seems to echo widespread concerns over “brain rot,” an internet slang term that the Oxford University Press defines as “the supposed deterioration of a person's mental or intellectual state.” (The term became so mainstream that the academic publishing house crowned it as its 2024 word of the year.)

A September review of 71 studies with a total of nearly 100,000 participants found that heavy consumption of short-form video was associated with poorer cognition, especially in regard to attention spans and impulse control, based on a combination of behavioral tests and self-reported data.

The review, published in Psychological Bulletin, a journal of the American Psychological Association, also found links between heavy consumption of the videos and increased symptoms of depression, anxiety, stress and loneliness.

A paper published in October, which summarized 14 studies of short-form video use, similarly described associations between heavy use and shorter attention spans, as well as poorer academic performance.

Despite growing alarm, some researchers say the long-term picture is still unclear.

James Jackson, a neuropsychologist at Vanderbilt University Medical Center, said there's a long history of people crusading against new technologies and cultural phenomena, whether it's video games or Elvis concerts. So he's cautious about overreacting to the rise of short-form video, but he said nonetheless that he believes many of the concerns are justified.

“The narrative that the only people who are worried about this are grumpy old grandpas who are yelling at you to get off their lawn or the idea that if you're concerned about this you're not in step with the times, I think that's really simplistic,” Jackson said.

Current research on the topic, he said, suggests that short-form video broadly seems to have harmful effects on the brain when it's consumed in large doses. But it will take more research to parse the nuances, such as who's most vulnerable, how permanent the effects are and which particular mechanisms cause harm.

Attention-deficit/hyperactivity disorder diagnoses are rising in the U.S. About 1 in 9 children had received an ADHD diagnosis by 2022, according to the Centers for Disease Control and Prevention.

Is brain rot real? Researchers warn of emerging risks tied to short-form video

From: NBC NEWS

With short-form video now dominant on social media, researchers are racing to understand how the highly engaging, algorithm-driven format may be reshaping the brain.

在短视频全面主导社交平台的当下，研究人员正竞相探索这种由算法驱动、极易沉浸的内容机制，是否会重塑大脑。

But increasingly, studies are finding associations between heavy consumption of short-form video and challenges with focus and self-control.

从TikTok到Instagram Reels再到YouTube Shorts，包括LinkedIn甚至Substack，短视频内容几乎已成为所有线上平台的核心组成部分。然而，越来越多的研究发现，高频刷视频与专注力下降、自律能力减弱之间存在关联。

cornerstone /ˈkɔː.nə.stəʊn/ 1）表示“基石；（尤指）奠基石”，英文解释为“a stone in a corner of a building, especially one with the date when the building was made or other writing on it”

The research, though still early, seems to echo widespread concerns over “brain rot,” an internet slang term that the Oxford University Press defines as “the supposed deterioration of a person's mental or intellectual state.” (The term became so mainstream that the academic publishing house crowned it as its 2024 word of the year.)

尽管相关研究仍处于早期阶段，但它们似乎呼应了人们对“脑腐”的广泛担忧。牛津大学出版社将这一网络俚语定义为“个人精神或智力状态的所谓退化”。（该词流行到足以被评为2024年年度词汇。）

A September review of 71 studies with a total of nearly 100,000 participants found that heavy consumption of short-form video was associated with poorer cognition, especially in regard to attention spans and impulse control, based on a combination of behavioral tests and self-reported data.

9月发表的一项综述分析了71项研究、近10万名参与者，结果显示，大量观看短视频与认知能力较差相关，尤其体现在注意力持续时间和冲动控制方面，该结论基于行为测试与自我报告数据。

cognition /kɒɡˈnɪʃ.ən/ 表示“认识；认知”，英文解释为“the use of conscious mental processes”如：a book on human learning, memory, and cognition 一本关于人类学习、记忆和认知过程的书。

on (an) impulse 表示“一时兴起，心血来潮”，英文解释为“because you suddenly want to, although you haven't planned to”

The review, published in Psychological Bulletin, a journal of the American Psychological Association, also found links between heavy consumption of the videos and increased symptoms of depression, anxiety, stress and loneliness.

这篇发表于《心理学通报》的综述还发现，频繁观看短视频与抑郁、焦虑、压力和孤独感症状的增加存在关联。

symptom /ˈsɪmp.təm/ 表示“（疾病的）症状”，英文解释为“any feeling of illness or physical or mental change that is caused by a particular disease”举个🌰：He's complaining of all the usual flu symptoms - a high temperature, headache, and so on. 他说他出现了所有常见的感冒症状——高烧、头痛等。

A paper published in October, which summarized 14 studies of short-form video use, similarly described associations between heavy use and shorter attention spans, as well as poorer academic performance.

10月发表的一篇论文总结了14项关于短视频使用的研究，同样指出重度使用与专注力减弱以及学业表现下降有关。

Despite growing alarm, some researchers say the long-term picture is still unclear.

尽管担忧不断加剧，但一些研究人员表示，长期影响仍不明朗。

James Jackson, a neuropsychologist at Vanderbilt University Medical Center, said there's a long history of people crusading against new technologies and cultural phenomena, whether it's video games or Elvis concerts. So he's cautious about overreacting to the rise of short-form video, but he said nonetheless that he believes many of the concerns are justified.

范德堡大学医学中心神经心理学家詹姆斯·杰克逊（James Jackson）表示，人们历来都会反对新技术和新文化现象，无论是电子游戏还是猫王演唱会。因此，他对短视频的兴起保持谨慎态度，但仍认为许多担忧并非空穴来风。

神经心理学家（neuropsychologist）指的是专门从事神经心理学研究和临床实践的专业心理学家。这一领域结合了心理学、神经科学和临床医学的知识，主要关注大脑结构与功能如何影响人的行为、认知和情绪。

crusade /kruːˈseɪd/ 表示“从事某运动；为达到某理想而奋斗”，英文解释为“to make an effort to achieve something that you believe in strongly”举个🌰：She crusaded against sex and violence on television. 她致力于反对电视节目中的色情和暴力。

“The narrative that the only people who are worried about this are grumpy old grandpas who are yelling at you to get off their lawn or the idea that if you're concerned about this you're not in step with the times, I think that's really simplistic,” Jackson said.

“有些人觉得，只有那些脾气古怪的老头子才会担心这件事——就是那种会冲你吼‘从我草坪上滚开’的老古董；或者认为你要是为此忧虑，就是跟不上时代——我觉得这种说法实在太简单粗暴了。”杰克逊说道。

narrative /ˈnær.ə.tɪv/ 作形容词，表示“叙述的，讲故事式的”，英文解释为“telling a story”如：a narrative poem 叙述诗。

作名词，1）表示“故事；叙事”，英文解释为“A narrative is a story or an account of a series of events.”如：a fast-moving narrative 一个快节奏的叙事。

Current research on the topic, he said, suggests that short-form video broadly seems to have harmful effects on the brain when it's consumed in large doses. But it will take more research to parse the nuances, such as who's most vulnerable, how permanent the effects are and which particular mechanisms cause harm.

他说，现有研究表明，大量刷短视频总体上似乎会对大脑产生有害影响，但仍需要更多研究来厘清细节，例如哪些人最易受影响、影响是否持久以及具体的危害机制。

dose /dəʊs/ 1）表示“一剂”（a measured amount of something such as medicine），如：a dose of penicillin 一剂青霉素；

2）表示“一些（糟糕或不愉快的事）”，英文解释为“an amount or experience of something, often something bad or unpleasant”举个🌰：He received a hefty dose of bad news this week. 本周他得到了许多坏消息。

📍《经济学人》（The Economist）一篇讲述谷歌的文章中提到：The first route would involve taking a strong dose of managerial medicine to become a more tightly run conglomerate. 第一种解决方法是给它服用一剂管理上的强效药，让它成为管理更严格的企业集团。
