The two economists call their paper "Mental Retirement," and their findings have aroused the interest of behavioral researchers. Data from the United States and 12 European countries suggest that the earlier people retire, the more quickly their memories decline.
The implication, the economists and others say, is that there really seems to be something to the "use it or lose it" notion—if people want to preserve their memories and reasoning abilities, they may have to keep active.
"It’s incredibly interesting and exciting," said Laura Carstensen, director of the Center on Longevity at Stanford University in California. "It suggests that work actually provides an important component of the environment that keeps people functioning optimally."
Researchers repeatedly find that retired people tend to do less well on cognitive tests than people who are still working. But, they note, that could be because people whose memories and thinking skills are declining may be more likely to retire than people whose cognitive skills remain sharp.
And research has failed to support the premise that mastering activities like memory exercises, crossword puzzles and Sudoku improve overall functioning.
"If you do crossword puzzles, you get better at crossword puzzles," said Lisa Berkman, director of the Center for Population and Development Studies at Harvard University. "If you do Sudoku, you get better at Sudoku. You get better at one narrow task. But you don’ t get better at cognitive behavior in life."
The study was possible, explains one of its authors, Robert Willis, a professor of economics at the University of Michigan, because the National Institute on Aging began a large study in the United States nearly 20 years ago. Called the Health and Retirement Study, it surveys more than 22,000 Americans over age 50 every two years, and administers memory tests.
Lisa Berkman claimed that crossword puzzles and some games could_____.
选项
A、not improve man’s overall functioning
B、make people good at one narrow task
C、help improve man’ s cognitive skills
D、help people live longer and slow down aging
答案
A
解析
细节题。短文第五段指出,研究者未能找出证据证明记忆练习、纵横拼字谜等可以提高人的全面功能。另外。第六段最后指出You get better at one narrowtask.But you don’t get better at cognitive behavior in life.即你仅在一项有限的任务上做得很好,但你不会在生活中的认识行为上表现得更好。故选项A正确。
