The magician, David Copperfield,
recently hosted an in-flight movie about how the brain deals with the thousands
of bits of information it is bombarded with constantly. Scientists have noted
one of the key traits we have as humans is to focus on one set of data,
thought, or sense while tuning out all others.
This has helped us survive whether it be chasing down prey in
prehistoric times or diffusing the ticking bomb on a McGiver re-run. We use the
ability unconscious throughout the day. It allows us to tune out the background
noise in a restaurant background so that we can have a conversation. It is not so helpful watching TV when we
become aware that dim buzz in the background is our spouse speaking to us.
Our brains cannot
consciously process two things at once but instead relies on switching from one
item to another. This trait has been long used by magicians (and pickpockets)
in creating distractions to pull rabbits out of hats, remove the watch from our
wrists, and put the pea in the unexpected shell.
This all came together in
understanding ‘multi-tasking”, something many claim to do. I was always amazed
to find my daughter listening to music while she did her homework while
carrying on multiple “chats” with her friends. Not that we are much different.
Before technology, we already had a long list of crazy things to do while
driving - reading a newspaper, shaving, putting on make-up. Now we’ve added texting,
watching movies, talking on the phone and web surfing to it.
In the documentary, scientists
found a man in Sweden renowned for multi-tasking. To test his ability, the man
was placed in a driving simulator with challenging road conditions and was
given simple arithmetic problems (e.g., 2+3-1) and words (e.g.,“mouse”) to
remember. Watching the experiment, I had no problem doing the arithmetic and
remembered most of the words. But I wasn’t driving! The renowned multi-tasker
got three arithmetic answers correct and could only remember one word.
The conclusion: There is no
such thing as “multi-tasking”. Were it not already a medical condition, a more
suitable name for “multi-tasking” might be “attention deficiency”. I don’t know if I suffer from a physiological
condition or if I am getting increasingly mentally lazy. But a word that my
wife and I are increasingly telling each other these days is “focus!”. I am
probably not alone.
