     Canadian scientists have found a method to help aging people get less forgetful by improving their

cognitive (认知) abilities through well-designed training. Everyone experiences some degree of memory

loss and cognitive decline as they get older. The decline usually becomes noticeable after 50, when

people may find it slightly more difficult to focus on tasks, organize everyday jobs and remember how

to do things in the right order.

     A team of psychologists (心理学家) in Toronto created a strategy (策略) of cognitive training to help

people preserve these abilities."Our primary emphasis was on improving the use of general strategic abilities

because they are particularly weak to the aging process," Dr. Donald Stuss, director of the study, said in

a press release. The team examined 49 healthy older adults with normal cognitive decline. All of the

participants were between the ages of 71 and 87. Over the course of 12 weeks, psychologists taught them

methods to improve their strategic abilities. Afterwards, researchers saw a 15 to 40 percent improvement

in the memories of all participants."Over a period of six months their improvement not only maintained, but

increased," said Dr. Gordon Winocur, coordinator of the study.

     The 12-week course was broken up into three four-week sections, focusing on a different skill involved

in strategic abilities: memory, goal management and psychosocial function.

     The memory training emphasized how to preserve and recover information, while goal management

focused on methods to lower the chance of memory slips. Psychosocial training was aimed at increasing

the participants' confidence in their mental abilities.

     "We wanted to develop a cognitive training program that would produce improvement over a relatively

short period of time, so participants could benefit more on that while they're still functional and slow down

the rate of decline," said Winocur. "If we can work with people in the early stages of cognitive decline, then

we can slow down the rate of this decline and help them maintain a higher level of function for a longer period

of time."
