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.'"

      An iPad can multitask more, it can do 3 tasks at once: you can put a beer glass, the bottle and some food on it at the same time!

    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.

    Task 1: Chewing gum.

    10 Chew Gum
    20 Goto 10

    Task 2: Listening to music

    10 Hear Music
    20 Shake head
    30 Hymn a little bit
    40 Shake leg
    50 Goto 10

    Task 3: Typing to Slashdot

    10 Think of words to type
    20 Search for the spelling of the word
    30 Lift fingers
    40 Use right fingers to hit the right keys
    50 Eye look at screen
    60 Check for typos
    70 Check for grammar mistake
    80 Goto 10

    If that's not multitask, what is?

    So if two is the limit, what does that say about men?
    Which head are they thinking with?

    I think the answer is obvious. Our two tasks are:
    1) Thinking about the woman we're are talking to
    2) Thinking about the other woman over there.

    Isn't your last task really two tasks in one? I mean what're your left fingers doing eh??

    Ahem, a delicate observation. Of course, it could mean you used your right (as opposed to wrong) fingers, but who knows what a slashdotter means

    Mea Culpa.

    Should have used the word "correct" instead of the word "right".
