Most people believe they can
multitask to some degree. Most people are wrong. Although we may think we’re
able to do several things at once, the truth is we’re just doing all those
things badly. In almost every case, people would do better to focus their
attention on one activity at a time. But are videogame players (VGP) the exception
to this rule? After all, if there’s any group that can rapidly react to
multiple stimuli, it’s them. Have they learned the secret to successfully
dividing their attention?
To find out, Sarah Donohue from
Duke University and her colleagues from Duke, Pennsylvania State University and
Colby College gave proficient VGPs and non-players a series of three tasks:
driving, multiple object tracking and image-search. For the first, they had to
play a driving simulation game. For the second task, subjects viewed eight
white dots on a screen. Four of the dots flickered a few times, and then all
the dots moved around the screen like a shell game. After twelve seconds of movement, the
participants had to identify which dots had been flickering. Finally, for the last
challenge, subjects were given a paper ‘find the hidden object’ puzzle form a
children’s magazine.
Volunteers ran through each of
these three tasks either without interruption (single-task), or while answering
trivia questions piped in over a loudspeaker (dual-task). The participants were
instructed to do their best at the original task (for example, to complete the
driving task as quickly as possible with no crashes) plus answer each question rapidly and accurately.
As I’m sure you’ve guessed, the VGPs
were no better at multitasking than the non-players. Both groups also showed
similar strategies for dealing with distraction, such as slowing down on the
driving course.
By the way, why did I say that most people can’t multitask? It turns out that about one out of every forty people is a ‘supertasker’ who really can concentrate on more
than one thing at a time. I’m definitely not in this group, as my family can
attest when they’re trying to speak to me while I’m reading something. If you
think you might be, this driving test might convince you otherwise:
