A. It takes time to process more data. B. An old adult doesn't have a good memory. C. But a team of scientists at the University in Germany has a different idea. D. Its performance is similar to that of an older adult. E. There is a small test between two people. F. This finding is based a computer program of learning and memory. |
Usually, we think older people's memories become bad because their brains get weak.
"The human brain works slower in old age," said lead scientist Michael Ramscar, "but only because they have stored more information over time. "Scientists let the computers read a certain amount of words and learn new things each day. When the computer "reads" only so much, its performance on cognitive （认知） tests is similar of a young adult. But if the computer learned the experiences we might encounter（经历）
Often it was slower because increased "experience" had caused the computer's database （数据库） to grow,This is similar to old people. Imagine a person knows two people's birthdays. Another person knows the birthdays of 2, 000 people, but can only match the right person to the right birthday nine times out of 10. Can you say the first person has a better memory than the second person?
