Smartphones
free up brain space but ruin memory
New leads |
Study by UK researchers say into sat-navs shows drivers who used Global
Positioning System remember less about their journeys
London:
Ease of accessing online contents through smartphones, tablets and laptops can
free up brain space, but it makes harder to remember details when unaided,
affecting our ability to recall information, British researchers said on
Wednesday.
Growing
options of wireless devices such as smartphones, tablets and laptops can
free-up mental resources by outsourcing unnecessary tasks to the gadgets.
However,
their scientific evidence also found the ease of access to online searches is
making it harder for humans to remember information without the help of a
computer.
“Remembering
your shopping list or an appointment is not the most effective use of your
cognitive resources and if you can be reminded of that task it frees-up more
space which can be used for a number of things,” said Sam Gilbert, a research
fellow in cognitive neuroscience at University College London and one of the
authors of the review published in ‘Trends in Cognitive Sciences’.
This
so-called “cognitive offloading” or the use of tools to reduce the demand on
our brains should strengthen our memories but other studies the experts
considered showed technologies are affecting our ability to remember details.
Research
into sat-navs showed drivers who used Global Positioning System remembered less
about their journeys and struggled to complete the routes again when unaided.
Another
study into the use of digital cameras showed those who took pictures in museums
could not recall as many details about exhibits as those who did not.
“There
is a clear need to better understand how offloading demands onto various
technologies impact on our organic abilities both in the short - and
long-term,” the review added. —PTI
