Research Suggests Brain Has a 2-Task Limit for Multitasking
suraj.sun writes with a story from LiveScience about just how much attention you can devote to each of the tasks on hand that scream for it: "The brain is set up to manage two tasks, but not more, a new study suggests. That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled. 'What really the results show is that we can readily divide tasking. We can cook, and at the same time talk on the phone, and switch back and forth between these two activities,' said study researcher Etienne Koechlin of the Université Pierre et Marie Curie in Paris, France. 'However, we cannot multitask with more than two tasks.'"

So how come I can't walk and chew gum at the same time?
I am chewing gum while listening to music and I am typing this into Slashdot.
Oh shit ! My brain gonna explode !!!
Muchas Gracias, Señor Edward Snowden !
I guess the researchers never played a Bach piece written for 3 voices. You have to play 3 different melodies with 2 hands, read ahead sheet music and keep the tempo. More than 2 tasks, right?
7 projects, 2 of which are corporate mandates with no additional funding or 'resources' to do them, 4 other administrative tasks, plus an hour or so each day dedicated to HR-related corporate marionette-ing to satisfy the Political Correctness Police. All for 2 shell scripts and a mainframe extract. That took 3 months to get done. And this isn't even a government job.
I call bullshit. Right now, I'm replying to this Slashdot article from my cell phone, eating a quick breakfast, and driving my car in morning traffic. I'm doing all three with the utmost saf
Is talking on the phone really a single task? Is cooking? Surely each of those is made up of countless sub-tasks even if you don't consciously think about them.
Somewhere not so long ago I saw research article that pointed out women can multi-task better than men.
And that it was a trait of women in general.
Its a matter of dealing with kids.
So if two is the limit, what does that say about men?
Which head are they thinking with?
I can eat, breath, type and read at the same time while listening to music.
At these moments I am also thinking ahead of what I am going to do.
Even typing could be considered doing several tasks at the same time. The sample of 'cooking' in the summery can be defined as multiple tasks. You are standing, you are tasting and smelling, you are planning of what to do next and probably stirring as well as looking.
For a chef in a kitchen, cooking is also interacting with other people at the same time.
For some people cooking is pressing the button on the microwave and waiting for the 'ting' of the machine.
So what is a 'task'?

I am typing this comment sitting in a library ogling a hot chick sitting in front of me while humming a tune and thinking about burgers. fur burgers.
What about professional musicians, who have to concentrate on far many more things than two at once? Organists, in addition to playing anything up to five keyboard manuals with their hands and one with their feet (simultaneously reading anything up to twelve lines of music, though in practice usually never more than five), have to listen to a choir and/or congregation, watch a conductor, and read the music, all at the same time. Some of them can even sing competently one line whilst doing so!
Whilst I can accept that it is very difficult to consciously concentrate on more than two things at once, somehow some people can train their subconscious into doing so -- when sight-reading music, I experience a lovely sensation, almost as if my brain is being "split" down the middle -- if I concentrate for too long, I start to develop a headache and feel exceptionally exhausted. It is a most wonderful feeling, and nothing else in the world quite comes close (although doing some rewarding mathematics isn't far behind). I would not be surprised if it were possible to find many more examples of people concentrating on more than two things at once, "simply" through getting other bits of their brain to do the dirty work. Juggling on a unicycle while jumping over a skipping rope, anyone?
My UID is prime. Is yours?
Of course, I was not able to hold the steering with my hands, but I was using my knee (was driving on the highway).
So this is 4 tasks at a time. I never had an accident.
Maybe 2 tasks in the foreground but its useful to have your computer checking mail, RSS feeds, defragging, etc in the background.
Thinking
Talking
Listening
Pick two.

I'm glad to see this. There are way too many people in my business life claiming to be good at multitasking when their only real strength is never giving anything their full attention.
It takes a certain amount of horsepower for your brain to help you get through a list of tasks, simple or not. When you focus, you get those things done faster, and usually at a higher quality.
So our brain is better at multitasking than an iPhone?
So the three-app limit in Windows XP was scientifically justified!

I recall an article at Arstechnica about cell phone use while driving mentioning a study that found a minority of people are actually capable of multi-tasking while the rest are "bad at it". Oh yes, here we go:
http://arstechnica.com/science/news/2010/03/rare-supertaskers-balance-driving-and-cellphone-use.ars
...all the researchers are men and have never met any women.
Try making a simple math operation inside your head while you are reading a book or writing an SMS.. Did you stop the reading or the SMS writing while you got the result of 22x11x2? You are not multitasking..sorry!
So we have a 2 processor system, but, at least for me, one of the two processors can also multi-thread.
Because I'm special. And superior to all other beings.

I had an accident and the zone of my brain which is responsible for the communication between the two hemispheres of the brain (corpus callosum) was damaged during a important head injury. Now it's difficult to take notes while listening to a speaker for example because I need to concentrate on two tasks.
So both hemispheres need to work actively but what is more important is the communication between them
The small brain takes care of the mechanical movements of the body, such as walking, swimming, dancing, bicycling etc.
As an aside, my brain is certainly restricted to a single task, since I'm an aspie.

LOL Dual core!
People do countless tasks every day at the same time, and "second nature" type tasks don't even come in to it.
People have to deal with multiple inputs every day and filter them correctly, be it someone taking some notes or a bartender in a busy club with loud music blaring.
Maybe they should rerun the tests on people like this.
I, personally, deal with multiple inputs almost every day and have no problem keeping track of them all.
The only downside for me is that i'm unable to do a lot of logical-heavy computation. But that is just for me, i know of others who are perfectly capable of it.
While we think we know a lot about how the brain works, we really are still pretty clueless. We don't know what any of those neural firings are doing, or mean, just that they are there and happening at the same time a task is being performed.
The brain isn't hardwired to deal with binary data, the main idea of the brain is to deal with countless inputs every nanosecond.
That is what led to it being so complex in such a small size. If the brain were to be expressed as a binary machine, it would be significantly larger.
People hate deciding between more than two things? That isn't the case at all, people like choice, and from my own experiences, most of the people i know usually tend to look for more options if they are presented with binary choices.
32 test cases just isn't a large enough dataset. Nowhere near large enough for something like this.
Hell, if there is one thing we DO know is that the brain is FLEXIBLE. Saying that the brain isn't capable of learning to multitask beyond some sort of "natural default" is just crazy, we have seen much bigger things than this, such as people echo-locating, brain adapting to alternative inputs such as UV and magnetic inputs, as well as emulated sight through stimulation of the TONGUE.
The brain is by no means a static structure.
And while we are at it, the definition of a task within the brain is a bit blurry, at best.
I can drink and drive, or drive and talk on the cellphone, but I can't drink, drive *and* talk on the cellphone.
Seriously though, you might be able to learn how to do that if you could practice doing that 100 times every day, for a month under safe simulated conditions (e.g. driving simulator, and simulated eating too, otherwise you'd end up killing yourself by overeating ;) ).
It's all about practice. Practice, practice, practice.
The first time you drive a car (especially a manual), there are so many tasks.
After a while of practice, your brain configures itself to automatically make those tasks into a subtask, and groups them all into one task - "driving".
Of course some people may never be able to do it. But I think a high proportion of people can. And I bet there are some people who can learn to do it after very short time - just like some people can learn to juggle very quickly, and there was that recent article about supertaskers.
I'm sure Michael Schumacher can eat breakfast and type on a cellphone and still do F1 laps faster than I can, when I'm just doing F1 laps (just driving, not eating or doing other stuff).
The trouble with most people is they're trying to do "for real" without practicing _properly_. That's like trying to juggle chainsaws, without learning how to juggle balls first, and then gradually working your way up under controlled conditions.
In my opinion, the type of task matters. And I think it has to do with what parts of your brain are used. For example, I can code/refactor and listen to a podcast just fine simultaneously. But if it's two comprehension-based tasks, like reading AND listening, I can't do them. Or lately I've even noticed I can't mentally elaborate on a thought and listen to a podcast at the same time.
The coding and listening thing seems very left brain/right brain to me.
Also, to the poster that mentioned musical multi-tasking... That's really interesting! But I think it helps that we as musicians have been training since a very young age to accept that level of multi-tasking, so the things that become muscle memory do. Fingering, breathing, sight reading, etc. Really the only thing that matters by show time is watching the conductor, the rest should be on semi auto pilot.
Some justification for talking on the cell phone while driving.
There is an example from R. Feynman, where he said he used to count the time in his head but he could not talk at the same time, whereas someone else could do that easily but he could not read a paper at the same time. OTOH Feynman could read the newspaper while counting time.
What was the difference? Feynman was counting time by narrating the numbers in his head (using the speech system), while the other guy was picturing the numbers in his head (using the image system). So if he was using the speech system he could not speak at the same time because that system was already in use, while the other guy could not read because he was already using the image system.

It's really all one thing - one movement. In other words, my wrists and feet where acting synchronously to the beat. The position for each body part would be different but the timing was the same. Probably the most impressive drummer I've ever heard was Omar Hakim - drummed for Sting on "Dream of the Blue Turtles". Sometimes I wonder if that guy's hemispheres actually communicate. Which makes me wonder of those folks whose hemispheres were disconnected wouldn't be awesome drummers or piano players.

Oh, that's easy: psychic implementation of parallelism. You're the one who's been using my brain all these years, which happily explains my occasional stupid moments: somewhere in the world, you're singing and using my brain.
This is because correlation yields causation, of course, and everyone who thinks otherwise is wrong--you can tell because causation is correlated with correlation.
Asa result, every once in a while, when you're sight-reading, I get this splitting headache and blurred vision of sheet music. What's worse is that it's all in Treble Clef...
Your brain controls all your bodies systems that keep you alive plus the two tasks they are saying . So your brain does a lot more then two things at a time
Core(tex) 2 duo?
So many posts bragging about being able to do a million different things at once. I don't think I can do two things at once. Once I get going I need a hardware interrupt to stop me. Usually it's the "desperately need to piss" interrupt.
So the hardware that is your brain is a dual core processor, but it's running a pretty rock solid OS that's able to coordinate threading and task scheduling fairly well without any noticeable lag time.
I think it's just the media trying to scare you into upgrading your brain to a quad core. Attack of the Cybermen!
How do people play RTSs then? Show me a good player of Warcraft, Starcraft or Supcomm and I'll show you a person that can manage at least half a dozen tasks simultaneously.

Multitasking is not as hard, as our zen masters teach us, as doing nothing at all ...

Seriously though, you might be able to learn how to do that if you could practice doing that 100 times every day, for a month under safe simulated conditions (e.g. driving simulator, and simulated eating too, otherwise you'd end up killing yourself by overeating ;) ).
It's all about practice. Practice, practice, practice.
When I first started practicing driving, it seemed like a chaotic cloud of different tasks -- pedal, clutch, brake, steering wheel. With time, they seemed to "bundle" together into one single task, mentally treating the separate threads as one process. I think a certain amount of shared context is needed though. Things like "fiddle with radio" or "adjust GPS" still feel like a separate task, no matter how many times I do it.
maybe it is limited logistically by our... two arms?
So we are all Core2Duo's at heart... That must mean those who multitask better are simply hyper-threaded.
Notice this article is popping up around the launch of the IPad, and on tech sites of all places? This is just a plant story to say that we all don't need multitasking because we humans can't do it. Sorry Apple, multi-tasking is a basic feature for about 30 years. And no fanboys, don't attempt to rationalize not having it.
Look at that article recently about justifying the A4 wasn't ready for multitasking. When u've been able to multitask since the first IPhone in 2007 by jailbraking it, it can do it.
When will you people learn?
Then please explain how a man can ride a horse, manage a herd, sing, watch for predators and obstacles, navigate, speculate on dinner, and wonder at the beauty.

Have you ever tried to seriously concentrate on a single task at hand.
* A Single vim/emacs session with a code or text. No Windows, No buffers.
* Or a single webpage open and you are concentrating on that one only.
You will switch only after one is over
Compare this with the multiple buffers open with multiple tabs and multiple applications open, which you constantly switch back and forth. It may not take a genius to figure that the first one is 'more efficient'. This research substantiates that.
I personally favor single tasking with a longer task switching.

Okay, the article seems a bit fuzzy but I haven't dug into the fine print of the study. But we from the computer world may think of "task" differently than the psychologists. Perhaps a better word for us is "Application", aka a whole connected series of subtasks. So I'd say your typing to slashdot is the ONLY "task" you have going. If you opened your email and worked on that, to me that would be Task/Application 2, still within "Brain Specs". So then if you were posting on a message board, per the study that's when I think it would get a little hairy, but they said "a bit muddled, not a total disaster".
However, I believe that things like chewing gum are more loaded into automatic/muscle memory areas (roughly cited source - Biology of Transcendence by Joseph Chilton Pierce). So if muscle memory is handling that one, it doesn't hit the limit of the two front line tasks. Then drawing from This Is Your Brain On Music by Daniel Levitin, music also hits different areas of the brain, and can serve to actually help some people, perhaps such as you, focus better on a different two tasks.

One could do a lot of things at once, but maybe is up to a few to actually solve new problems instead of being just receptor (reading, watching tv, hearing music, probably recognizing patterns in that input) or do a somewhat automated thing (walking, eating, even writting what you are thinking).
Talking with a cellphone while driving could fall into this category, you have one task thinking in what you are talking, and if you try to solve something else you could be out of tasks to solve the problem on how to avoid the next obstacle.
When you practice doing two tasks simultaneously, they become a new, single task. How do good drummers play syncopated beats? You learn a multitude of "keeping the beat" tasks involving many combinations of common patterns on the bass drum, hi-hat, and ride cymbal, then you learn a variety of syncopated beat tasks to play "overtop" of the other task. (You also have to learn strategies for performing these tasks at the same time, especially when you have to borrow a foot or hand from the keeping-the-beat task for an accentuated part and then un-borrow it; however, my point---namely, for a good drummer, many complex patterns involving multiple limbs, when practiced sufficiently, become simply "one task"---still stands.)

If there's one thing I've learned in my 4 decades on this planet, is when you say something, peeps prove ya wrong.
Most of us probably can only multitask 2 things at a time, but saying thats all humans can do?
Sorry, I'm more then sure there's peeps who can do 3 or 4 things at a time, while there's some who can only do 1 thing, or not anything.
Be seeing you...
I'm doing that and eating a bowl of cheetos!
Using your drum analogy then people can only do 1 task.
And if I add a 2nd task of "chewing gum" to the singular task of playing multiple drums? Then you can say, well, with practice chewing gum and playing drums becomes a new single task.
Then if I say, well, he is doing the single task of chewing gum and playing multiple drums and then added the 2nd task of singing (Phil Collins for example)
The you'd say well, with practice that becomes a single task, playing multiple drums, chewing gum, and singing is really only one task.
So now we have the single task of singing, chewing gum, and playing multiple drums and then we add the 2nd task of thinking what song to perform next based on the crowds reaction to what you are currently playing.
So now, with practice, you can say we are single tasking when playing multiple drums, chewing gum, singing, judging the crowds mood, and planning what song to play next.

Two hardware threads doesn't mean you can't do more than two tasks. It just means that you will incur a task switch penalty. How large that penalty is depends on how fast you context switch and how big your thread local storage is.
Yes but when it multitasks is it a fork or a pthread?
We can also JUGGLE tasks. So they are not SIMULTANEOUS tasks but more a rapid switching between multiple tasks. The switching being fast or slow, but nevertheless more than two task can be achieved in parallel.
I have pretty severe ADD (diagnosed since childhood, have used various ADD medication, etc) and I am by far my most productive in situations where i need to multitask about 4 things. 1 is nearly impossible to do, 2 is not enough, and more than 6 starts to become difficult.
It is important to note that the type of task - things that still remain impossible for me to multitask are include hard math problems, tracing bugs though code, and other things that require many linear steps with lots of temporary information in my working memory.
why use classes and objects for stuff that do not have nature of an object ?
none of the elements you put into the classes (and therefore going to use as objects) exhibit object properties at any point. there is little difference in treating them objects, or flat out functions or blocks of code.

Tap eighth notes with your left hand. Tap triplets with the right hand at the same time. At first you'll probably trip over this, but after a while you'll figure out that it's a pattern that goes ||:[both]-[pause]-[right-left-right]-[pause]:||. That is, the two previously separate patterns become just one pattern using both hands.

I heard that someone named Harry Kahne in 60s or 70s did a literal multitasking. Does this mean that, with practice, you can push the limit up to 4 or 5(I'm not sure how many he insisted)? On second thought, I guess you can with practice anyway..
I've always found if I need to get through a monotonous task that turning on some music or talk radio helps me focus. My parents in high school thought I was full of crap to put on some Tull records to study history, but I still do it today when I have a deadline (less Tull, more Free Talk Live). Not having the distraction opens me up to all kinds of "ooh, shiny" weakness.
So, I wonder if somehow one of my two task slots needs to get filled up so the other one can get the work done. I probably have some weakness in sticking tasks to a particular slot or something like that, or perhaps they bounce back and forth causing some opportunity for leakage (I know, stretching the metaphor). I try to resist the term 'ADD' because I can concentrate like hell at times, but 'leaky task slots' feels right.
My God, it's Full of Source!

Most are missing the point entirely. A computer can only do ONE THING. The on/off or hi/lo thing. But it can do it very quickly. The research says we can do TWO things AT THE SAME TIME! Like two processors running in parallel. Geddit?
... that LiveScience has a two bit limit for understanding what they publish and so can get correct. These are the people that produced the 'top 10 mysteries of the brain' some of which had nothing to do with the brain. If they understood what they read, they'd not reprint such drivel laden press release pubs.
I don't expect them to know about the study that found human facial recognition in the brains of dead salmon. That was a real study and required some actual background knowledge. But you have to wonder why they persist in reprinting fMRI stories that fail to show all the relevant parts of the brain operating rather than just the one that controls one function involved. (In TFA frinstance, switching tasks means switching attention which means anterior cingulate. So where is it?) It's probably because the articles have those pretty pictures of colored lights in the brain -- which they fail to include in their reprintings.
So of the two 'things', what's a thing? Per their example, cooking takes at least two tasks (recipe/memory and mixing/motor) and switching between them requires attentional control which is a third. Add the phone and you get a second attentional control function as well as language comprehension and language production. So there's six. Now what happens if you drop the phone into the cake batter? An executive function has to monitor constantly in case novel response is required. Seven. An emergency motor function kicks in that lets you try to catch it. Eight, if called upon.
As for the relationship between TFA and decision making, it is certainly worthwhile to read such scientific wisdom as 'might' 'seem' 'don't appear' and 'perhaps'. Which suggests the question, 'how many "things" is a hypothetical'? One question? One for each possibility? In any case, considering the hypothetical connection between TFA and decisions is a complex collection of interacting items to compare and contrast. Despite the fact that they are unaware they're doing it, the "science" "writers" and LiveScience juggle a fair amount of items in the last section. But just so we don't overtax them, let's let them continue to think they're comparing 'one science thingy' (that's one!) with 'another science thingy' (oh, wait. that's um... there's one and then.... darn, this thingy and thingy stuff is hard).

It is axiomatic that humans can dual-task well? Since when? Citation needed. In fact University of Utah researcehrs that is the rare 2.5% of the population that can truly "supertask" two activities without any loss in efficinecy. For example, drive and talk on a mobile. Citation needed?

All such claims regarding brain function need to be taken with a pinch of salt. The "brain" as a whole clearly multitasks over a very wide range of activities. For instance, balance, coordination of skeletal muscles, vocalisation, temperature regulation, eye movement, aural, optical, tactile and chemoreceptor monitoring. That's just a few of the host of parallel processing capabilities. There are, of course, many more. The greatest source of misunderstandings in this regard is our habit of considering the conscious activies as the main (and cleverest) part of the brain. brain. It is not so, for if considered carefully enough, the subconscious, represented mostly by the cerebellum, hypothalamus and related structures is seen to be way "smarter". The the much-vaunted "conscious" is basically a navigational facility used for interaction with the external environment. It requires extensive memory storage and processing systems in order to form and manipulate internal models of the external environment. Analogous to map-rooms. Since our interactions with our environment are far more complex than those of other species the main locus for the memory required for these map-rooms are the cerebral hemispheres. These considerations are discussed at greater length in chapter 6 of my recent book “Unusual Perspectives”, the full electronic edition of which can be freely downloaded from the eponymous website.
That's because, when faced with two tasks, a part of the brain known as the MFC divides so that half of the region focuses on one task and the other half on the other task.
No wonder the brain is so limited, it's written using MFC. C'mon god, don't you know that Cocoa Touch is this century's class library du jour?
