Having a good memory
doesn’t depend on intelligence but on how you use your
brain, according to a recent study. Moreover, individuals
can actually improve their memory by learning some simple,
memory-boosting strategies.
The study compared
the brains of 10 participants in the World Memory Championships
who have above-average memories with 10 people with normal
memories. Both groups had "high-average" intelligence
and identical brain structures, however, the groups used different
parts of the brain during memory tests.
Close to all of
those in the exceptional memory group used a strategy, known
as a mnemonic, for increasing memory that involved visualizing
items to be remembered. Researchers say that this device likely
activated a part of the brain called the hippocampus, which
involved in spatial memory and was activated among those in
the top-memory group.
Researchers say
that it may be possible to improve memory by using strategies
that engage certain parts of the brain. This practice could
potentially be extended to helping people recover from memory
loss due to injury.
