If your smarts slow down or stop ticking at times, you may be pushing in directions that intelligence simply cannot go. Your brain comes equipped with a neural bottleneck that thwarts multi-tasking … according to researchers at Vanderbilt University. So what?
What does that say about people who tend to do many things at once? Neuroscientists Paul E. Dux and René Marois found that when we handle even two things at once, the brain slows down.
It would seem that with 100 billion neurons processing information at rates of up to a thousand times a second, a person could do two tasks at once, without a problem. Not so.
The problem with too much information creates an attention bottleneck that leaves you unable to sleep but feeling exhausted and overwhelmed according to researchers Nuno Sousa and others.
Researchers described a central “bottleneck” that exists in the brain and prevents people from doing two things at once. Check out the results published in the Dec. 21 issue of Neuron. Could this research contribute to a ban of cell phone use while driving.
Scientists found that that a central bottleneck is created by inability of the lateral frontal and pre-frontal cortex, and also by your superior frontal cortex - to process two tasks at the same time. How many are you trying to juggle?
Because of the hard data here, neither Marois nor Dux use their cell phones while driving. In fact they report that dual-task slow down can literally lose the driver up to a second, and that could create a crash when faster response times are needed to make a critical judgment. Yikes!
My question is, what does this research say about communicating with passengers while we drive? What do you think?
