Habitual Multitaskers Do It Badly 386

Posted by timothy from the please-pass-the-toast-and-jelly-and-scalpel dept.
iandoh writes "According to a group of Stanford researchers, people who frequently multitask don't pay attention, control their memory or switch from one job to another as well as those who prefer to complete one task at a time. In other words, multitaskers are bad at multitasking. The research team is also studying how to design computer voices for cars that result in safer driving." Reader AliasMarlowe adds "The comparison involved multitasking with a number of attention or context related tests. For the study, multitasking was defined as consuming multiple media sources at once — gaming, TV, IM, email, etc. Interestingly, the habitual multitaskers were much worse at multitasking than the single taskers in these relatively straightforward tests. In self-assessment the multitaskers considered themselves good at it and the single taskers considered themselves bad at it. An extreme case of the Dunning-Kruger effect, perhaps, with consequences for business and society."

      I multitask a lot, but I've only been doing it after learning how a computer does it - you know, that same computer INCAPABLE of real multitasking? Yeah, humans should do it like that as well.

      The trick is to use a divide and conquer algorithm on your tasks and divide them into chunks of just the right size - too small and you'll have too much overhead switching processes, too little and you'll essentially reach a dead-lock situation where everything is waiting for you to finish that one thing.

      What works for me is, for example, reading a chapter of a textbook, followed by a few minutes on slashdot and whatnot, then going back to the book and so forth ad nauseum.

      This way you're always multitasking without actually multitasking and you get a lot more done than just focusing on one task for a few hours, then on another for a few more hours and so on.

        Good for you on being able to schedule your time and attention productively, but the above isn't what I would call multitasking.

        It's been shown that the average attention span runs about 20 minutes. After that, you _will_ lose the ability to concentrate and your mind will naturally wander. This new period lasts about 5 minutes IIRC. Once that ends, you're refreshed enough go back to what you were doing with renewed concentration.

        Mind you, you're free to invoke "willpower" to circumvent that natural ebb and flow, but your performance will suffer, and you'll accomplish half the work for twice the effort. With enough motivation or adrenaline, you'll manage just fine, but like missing few hours from a restful night's sleep to cram more workhours into your day, you'll discover diminishing returns.

        So by all means, do browse Slashdot for a minutes. If your disciplined enough to avoid non-essential or otherwise unproductive activities generally, it'll help you work and get more done.

If we're really discussing two different types of absorbtion, purely visual and audio/visual, and the tests are made up of entirely visual questions, aren't the researchers tipping the scales in favor of the purely visual non-multitaskers? From the article: "A survey defined two groups: those who routinely consumed multiple media such as internet, television and mobile phones, and those who did not." The ones not consuming multiple media are consuming what? My guess would be books and newsprint, and if so, are they visual learners? How did they control for intelligence level? If the visual group is on average smarter than the audio/visual group, would that not also skew the results? More information is needed and less conjecture.

        Now, I admit fully to being resolutely anti-corporate, so it's only natural for me to look at this suspiciously. But I have to imagine that a whole lot of other people will see this as a disorder not just of the worker but of management, accepting sight unseen that multitasking, getting bits and pieces done on a whole lot of different projects in short order, is somehow more "efficient" (Hello? Changeover time?) than doing one thing to a good stopping point and then moving to another project when you're damn good and ready. It's especially a management problem if the management insists on mandating the changeovers, forcing employees to change gears without the clutch engaged.

When it was a big buzzword and something taught in our studying class (yes, multitasking, as a strategy of getting studying done in your busy life... like in-between stupid timewasters), I just noticed how before when I could think through something like a challenging math problem or concept, even if it was hard to do so, I had to start relying more and more on the back of the book and work the answers backwards.

      Basically, a guy wanted to find out what the differences are between those who multi-task a lot and those who don't, or feel they are unable to multi-task well.

      He set up an arbitrary experiment that supposedly tests your ability to multi-task and those who multi-task a lot did not do very well at his experiment, hence his conclusion was that multi-taskers are bad at multi-tasking.

      The problem I see with his experiment, and more importantly, his conclusion, is that he assumes the various tests he did actually are all that are required to judge someone's ability to multi-task - effectively he wasn't testing multi-tasking in his experiments, only performing phsycological tests that he assume are the traits that are required to be an effective multi-tasker.

      An experiment cited in the BBC article is one where there is a screen with 2 red rectangles and a number of blue rectangles which is displayed briefly and then the screen is displayed again and the subject has to say whether or not a red rectangle has been rotated. The link to multi-tasking in this particular experiment is weak, I can only guess the assumption is that to multi-task better you need to be able to track multiple objects on screen in detail but that seems to be merely speculation on behalf of the researcher.

      Doing research on this sort of thing is fair enough, but the fact they seem to have come to the outright conclusion that multi-taskers suck at multi-tasking seems quite a leap from what their research actually shows - that there's simply a statistical link between someone's ability to multi-task and how badly/how well someone can do in those specific experiments which in themselves may or may not tell us anything about someone's ability to multi-task.

      I would've thought a better experiment would, you know, involve multi-tasking? An experiment with say a simplified user interface where there are multilple blocks (Windows) where a basic task has to be performed in each but each has a differing time limit as to how quickly it must be completed. Simple, effective, and a good test of multi-tasking ability.

      But then, that might not have given them the results they wanted that would get them headlines that the world's media would blindly follow.

Not saying this is necessarily good, just not clear how this was testing multi-tasking.

    It seems to me a "multi-tasker" would do better at a test that actually tested tracking multiple inputs at once.

    I can involve myself in one high-level function and monitor several low-level functions no problem. If I'm cooking and it's a recipe I know, I can have something on the telly in the background. Certainly not a movie or something that requires 100% focus but I can put the Daily Show or Colbert on no problem, just glancing over during the laughs to catch the sight gag. If it's a recipe I'm unfamiliar with, I have to focus 100%, no time for distractions.

    Driving is another interesting case. When I was first learning, I couldn't have the radio on or even talk with a passenger. It was a new skill and consumed 100% of my attention to a ridiculous degree. As I became more comfortable with driving, I could take a more relaxed approach. I can hold a conversation with a passenger. I'm still doing my sweeps, checking mirrors, instrument panel, paying attention to the feel of the road, listening for anything odd, but it takes less effort to do all these things. But when conditions become more interesting, it takes more effort to retain situational awareness. I'll lose track of the conversation. This is the opposite of the way most people do it, the conversation distracting from the driving.

    As a mostly monotasker, I'm very skeptical of multitaskers, bordering on contemptuous. It really irks me when I'm trying to work with someone who insists on multitasking to the point where you keep having to repeat yourself because he wasn't fucking listening in the first place. "No, I heard what you said. Just repeat it so I can understand." It's a sick, pathetic, constant pattern. I tell someone x is followed by y and z. They hear x and immediately ask about c. Well, c could be related in some instances but I already told you in this instance it's x, then y, then z. But wait, why is y there? That's the sequence. And then after several more rounds the person will exclaim with a sudden revelation "Why, this is x, then y, then z!" Of course, you numpty pillock. I've only been trying to tell you that for the last ten minutes. I'm going to rip that fucking bluetooth out of your ear, yank the battery from your iphone (they are removable if you use enough force) and make you focus for a goddamn minute!

      I think you have a good point here, the most important part of multitasking isn't how many tasks you do at once, but how well you prioritize, as different tasks start to use up more of your internal resources you have to know which tasks to drop and which to keep. This is a common problem, people who keep the cell phone conversation instead of the focus on driving for example.

      I used to work tech support, the majority of calls were dead simple and required very little thought on my part, it was quite common

  • No, not that kind of multitasking! I mean have they corrected for the difference between men and women?

    In our society, and in the hunter-gatherer societies that far preceded it, men's jobs demanded concentration and women's demanded social interaction. This may introduce a sex-linked bias into the experiment.

  • I have long suspected this. I think people who believe they are good at multitasking give themselves the illusion that they are doing a good job simply because they are so busy. It has been my observation that many women, in particular, pride themselves on their multitasking ability, and are confident that they are excellent at each and every task, when in fact they are just doing a mediocre job.

    Pity the poor man who should ever suggest this, however.

    Yes, I can multitask by reading a book and riding a stationary bike with no appreciable impact in performance of either. I can run and catch a football. I can walk down the hall and carry on a conversation. I can answer emails and listen to music.

    All of these examples involve one activity that requires attention and one that does not require attention.

    Where humans can't multitask is when two or more activities require attention. A classic example is driving and talking on a cell phone. Most people think that they can do this effectively. They are ALL wrong. They believe this because of two phenomena (1) for the most part, driving is fairly autonomous, only occasionally does it require attention (2) if your attention is on your phone conversation, you tend to miss those times when driving does require your attention unless something interrupts your attention like you have an accident or someone honks a horn at you for driving like a jackass. For the most part, these drivers are blissfully ignorant of their ineptitude behind the wheel.

    Most people who think they can multitask with other activities are wrong for the same reasons. I've yet to see someone with an open laptop in a meeting freely contribute to the process and often they force everyone else in the meeting to backtrack when their input is actually required.

      Analysis depends on where you parse your task units. Walking miles while focusing intently on the scenery and composing a complex poem and committing it to memory can be two separate tasks, competing for attention, or they can be one single task. Making them one task was the poetic practice of Wordsworth as well as of Wallace Stevens, Basho, and Gary Snyder. Similarly listening to the melody line of a single instrument may be one task, and listening to each of the other instruments in an ensemble separate t
