| Older
adults with memory problems can gradually increase their ability to recollect
information through a simple exercise, according to a study reported in the September
issue of Neuropsychological Rehabilitation.
Janine Jennings
of Wake Forest University and Larry Jacoby of Washington University
were able to improve the memories of a group of older adults whose
average age was 73 by showing them one word at a time from a list,
and asking them to remember certain words that had already appeared
on the list.
After
seven days of training for about 45 minutes each day, the participants performed
an average of 14 times better on the memory task.
Jennings said
the memory training in this study is based on the theory that
memory consists of two processes -- the automatic process of familiarity
and recollection. The automatic memory process lets a person know
that someone they see is familiar.
When
someone begins searching their memory for why that person is familiar or when
they last saw him, Jennings said they are using the second, more difficult memory
process called recollection.
Specifically,
we want to improve the recollection process -- the labor-intensive
part of memory," Jennings said, noting that it would be helpful
if older adults could strengthen the ability to recollect something
following a delay.
"The
next question to answer is whether the effects occur outside the lab and make
a difference in people's everyday memory function," Jennings observed. Other
