Big Think, Multitasking Is a Myth, and to Attempt It Comes at a Neurobiological Cost.

Multitasking Is a Myth, and to Attempt It Comes at a Neurobiological Cost.

Daniel Levitin: It turns out that multitasking is a myth. We think that we're doing a whole bunch of things at once. But we're not actually because the brain doesn't work that way. In a number of studies now have shown from Earl Miller's lab at MIT and others that what we're really doing is we're paying attention to one thing for a little bit of time and then another and then another and then we come back around to the first. And all of these are separate projects that are occurring in separate parts of the brain, they require a separate start time, a separate monitoring process. And you end up fractionating your attention into little bits and pieces, not really engaging fully in any one thing. All that switching across tasks comes with a neurobiological cost. It depletes resources. So after an hour or two of attempting to multitask, if we find that we're tired and we can't focus, it's because those very neural chemicals we needed to focus are now gone. There are some jobs that require, not multitasking because we know it doesn't exist but this kind of a rapid switching, I'm an air traffic controller, simultaneous translator at the UN, journalists, monitoring all these different things at once. And we can take a tip from the air traffic controllers who, as part of their duty cycle, are required after every hour and a half or two hours of work it's mandated that they take a 15 to 30 minute break. And that means an unplugged disconnected break where they go for a walk or listen to music, they exercise, something to restore all of the burned up neurochemicals.

You might ask during this period of our evolution when there's all this information is the brain adapting and changing? And yes it is. The brain adapts and changes all the time. Evolution is happening all the time. Unfortunately it's rather sluggish. We talk about it in terms of evolutionary lag and generally speaking it takes about 20,000 years for the brain to catch up with the way the environment is in terms of how it's encoded in the genome. So 20,000 years from now our brains may have evolved to deal with it. In the meantime we have to employee strategies, just a little bit more self-disciplined then we currently use to filter out unwanted or unnecessary input. I'm not talking about never letting something frivolous or fun in, but I'm talking about adopting a kind of a habit of allowing yourself to focus on one thing at a time for at least a few hours a day.

Vários estudos do laboratório de Earl Miller no MIT e outros demonstraram que o que estamos realmente a fazer é prestar atenção a uma coisa durante algum tempo e depois a outra e depois a outra e depois voltamos à primeira. В ряде исследований, проведенных в лаборатории Эрла Миллера в Массачусетском технологическом институте и других, было показано, что на самом деле мы обращаем внимание на одну вещь в течение некоторого времени, затем на другую, затем на третью, а потом возвращаемся к первой. Earl Miller'ın MIT'deki laboratuarında ve diğerlerinde yapılan bir dizi çalışma, aslında yaptığımız şeyin bir şeye bir süre dikkatimizi verdikten sonra başka bir şeye, sonra başka bir şeye dikkatimizi verip tekrar ilkine dönmek olduğunu göstermiştir. 麻省理工学院 Earl Miller 实验室和其他人的多项研究表明,我们真正在做的是,我们只关注一件事一段时间,然后关注另一件事,然后再关注另一件事,然后我们又回来了到第一个。 And all of these are separate projects that are occurring in separate parts of the brain, they require a separate start time, a separate monitoring process. ||||||tasks or activities|||||distinct|regions|||||need|||beginning point||||tracking or observing|monitoring method E todos estes são projectos separados que estão a ocorrer em partes separadas do cérebro, requerem uma hora de início separada, um processo de monitorização separado. И все это отдельные проекты, которые происходят в отдельных частях мозга, они требуют отдельного времени запуска, отдельного процесса мониторинга. Ve tüm bunlar beynin ayrı bölümlerinde gerçekleşen ayrı projelerdir, ayrı bir başlangıç zamanı, ayrı bir izleme süreci gerektirirler. 所有这些都是发生在大脑不同部分的独立项目,它们需要一个单独的开始时间,一个单独的监控过程。 And you end up fractionating your attention into little bits and pieces, not really engaging fully in any one thing. ||||teilen||||||||||||||| ||wind up||dividing|||||small parts||small parts|||fully participating in|completely||a single task|| And you end up fractionating your attention into little bits and pieces, not really engaging fully in any one thing.

Ve sonunda dikkatinizi küçük parçalara ve parçalara ayırırsınız, herhangi bir şeye tam olarak odaklanamazsınız. 你最终会把你的注意力分散成一点点零碎的东西,而没有真正全神贯注于任何一件事。 All that switching across tasks comes with a neurobiological cost. ||Wechseln||||||| |||between different tasks|activities||||brain-related| ||switching||||||| All that switching across tasks comes with a neurobiological cost.

Assim, após uma ou duas horas de tentativas de multitarefa, se nos sentirmos cansados e não conseguirmos concentrar-nos, é porque os químicos neurais de que precisávamos para nos concentrarmos já desapareceram. Так что если через час или два после многозадачности мы обнаруживаем, что устали и не можем сосредоточиться, это потому, что те самые нейронные химические вещества, которые были нужны нам для концентрации внимания, теперь исчезли. Yani bir ya da iki saat çoklu görev yapmaya çalıştıktan sonra, yorgun olduğumuzu ve odaklanamadığımızı fark edersek, bunun nedeni odaklanmak için ihtiyaç duyduğumuz sinirsel kimyasalların artık yok olmasıdır. 因此,在尝试同时处理一两个小时后,如果我们发现自己疲倦且无法集中注意力,那是因为那些我们需要集中注意力的神经化学物质现在已经消失了。 There are some jobs that require, not multitasking because we know it doesn't exist but this kind of a rapid switching, I'm an air traffic controller, simultaneous translator at the UN, journalists, monitoring all these different things at once. |||work roles||||||||||isn't real||||||quick transitions|rapid task shifting|||||traffic manager|at the same time|simultaneous interpreter|||United Nations|news reporters||||varied tasks simultaneously||| Há alguns trabalhos que requerem, não multitarefa porque sabemos que não existe, mas este tipo de mudança rápida, sou controlador de tráfego aéreo, tradutor simultâneo na ONU, jornalistas, monitorizando todas estas coisas diferentes ao mesmo tempo.

Bazı işler vardır ki, çoklu görev gerektirmez çünkü böyle bir şeyin olmadığını biliyoruz ama bu tür hızlı geçişler, ben bir hava trafik kontrolörüyüm, BM'de eş zamanlı çevirmenlik yapıyorum, gazeteciyim, aynı anda tüm bu farklı şeyleri izliyorum. 有些工作需要,不是多任务处理,因为我们知道它不存在,而是这种快速切换,我是一名空中交通管制员,联合国的同声传译员,记者,同时监控所有这些不同的事情。 And we can take a tip from the air traffic controllers who, as part of their duty cycle, are required after every hour and a half or two hours of work it's mandated that they take a 15 to 30 minute break. ||||||||||||||||||||||||||||||||vorgeschrieben||||||| |||||piece of advice|||aviation industry professionals|aircraft movement|air traffic managers||||||work schedule|work period||mandated to take||||||90 minutes|||periods of work||||required by rule||||||short period|short rest period |||||a suggestion|||||||||||dovere|cycle|||||||||||||||||||||| E podemos seguir o exemplo dos controladores de tráfego aéreo que, como parte do seu ciclo de trabalho, são obrigados a fazer uma pausa de 15 a 30 minutos após cada hora e meia ou duas horas de trabalho.

Görev döngüsünün bir parçası olarak, her bir buçuk ya da iki saatlik çalışmanın ardından 15 ila 30 dakika mola vermeleri zorunlu olan hava trafik kontrolörlerinden bir ipucu alabiliriz. 我们可以从空中交通管制员那里得到一个提示,作为他们工作周期的一部分,他们需要在每工作一个半小时或两个小时后休息 15 到 30 分钟。 And that means an unplugged disconnected break where they go for a walk or listen to music, they exercise, something to restore all of the burned up neurochemicals. ||||nicht angeschlossen|getrennt|||||||||||Musik||||||||||| ||signifies||disconnected from technology|uninterrupted|||||||||pay attention to||songs or tunes||work out|||replenish||||depleted||brain chemicals ||||desconectada|desconectado||||||||||||||||||||||neuroquímicos E isso significa uma pausa desconectada e desligada em que vão dar um passeio ou ouvir música, fazem exercício, algo para restaurar todos os neuroquímicos queimados. А это значит, что нужно сделать перерыв на отдых, чтобы прогуляться или послушать музыку, заняться спортом, чтобы восстановить все сгоревшие нейрохимические вещества. Bu da yürüyüşe çıktıkları, müzik dinledikleri, egzersiz yaptıkları, tüm yanmış nörokimyasalları geri kazanacakları, fişten çekilmiş bir mola anlamına gelir. 这意味着不插电的休息时间,他们可以去散步或听音乐,锻炼身体,恢复所有燃烧的神经化学物质。

Мы говорим об этом в терминах эволюционного отставания, и в целом мозгу требуется около 20 000 лет, чтобы догнать окружающую среду с точки зрения того, как она закодирована в геноме. Bu konudan evrimsel gecikme açısından bahsediyoruz ve genel olarak konuşursak, beynin genomda nasıl kodlandığı açısından çevrenin durumuna yetişmesi yaklaşık 20.000 yıl alıyor. 我们从进化滞后的角度来谈论它,一般来说,大脑需要大约 20,000 年的时间才能赶上环境在基因组中的编码方式。 So 20,000 years from now our brains may have evolved to deal with it. |||||minds|might have possibly||adapted or changed||handle or manage|| Portanto, daqui a 20 000 anos, os nossos cérebros poderão ter evoluído para lidar com isso.

In the meantime we have to employee strategies, just a little bit more self-disciplined then we currently use to filter out unwanted or unnecessary input. それまでの間、私たちは戦略を採用しなければなりません。不要な入力や不必要な入力を除外するために現在使用しているよりも、もう少し自己規律を高める必要があります。 Entretanto, temos de utilizar estratégias, um pouco mais autodisciplinadas do que as que utilizamos atualmente, para filtrar as informações indesejadas ou desnecessárias. А пока мы должны использовать стратегии, чуть более самодисциплинированные, чем те, которые мы используем сейчас, чтобы отсеивать нежелательные или ненужные данные. Bu arada, istenmeyen veya gereksiz girdileri filtrelemek için şu anda kullandığımızdan biraz daha disiplinli çalışan stratejilerine ihtiyacımız var. 与此同时,我们必须制定员工策略,比我们目前用来过滤掉不需要的或不必要的输入更自律一点。 I'm not talking about never letting something frivolous or fun in, but I'm talking about adopting a kind of a habit of allowing yourself to focus on one thing at a time for at least a few hours a day. |||||lassen||oberflächlich||||||||annehmen|||||||||||||||||||||||| |||||permitting||unimportant or fun||enjoyable activity||||||taking on|||||routine||permitting||||||||||||minimum of||a small number|||per day Ich rede nicht davon, dass man nie etwas Belangloses oder Spaßiges zulässt, sondern davon, eine Art Gewohnheit anzunehmen, sich zumindest ein paar Stunden am Tag auf eine Sache zu konzentrieren.

Я не говорю о том, чтобы никогда не позволять себе что-то легкомысленное или веселое, но я говорю о том, что нужно взять за привычку позволять себе сосредоточиться на чем-то одном хотя бы на несколько часов в день. Anlamsız veya eğlenceli bir şeye asla izin vermemekten bahsetmiyorum, ancak günde en az birkaç saat boyunca tek bir şeye odaklanmanıza izin verme alışkanlığı edinmekten bahsediyorum. 我不是说永远不要让琐碎或有趣的事情进来,而是要养成一种习惯,让自己每天至少花几个小时一次专注于一件事。
