Grown-ups are often surprised by how well they remember something they learned as children but
have never practiced ever since. A man who has not had a chance to go swimming for years can still
swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still
ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the
words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember
the story of Cinderella or Goldilocks and the Three Bears.
One explanation is the law of overlearning , which can be stated as follows: Once we have learned
something, additional learning trials (尝试) increase the length of time we will remember it.
In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing
baseball long after we have learned them. We continue to listen to and remind ourselves of words such
as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn
but overlearn.
The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather
quickly the things that we learn in school, because they are another of the things we overlearn in
childhood.
The law of overlearning explains why cramming (突击学习) for an examination, though it may result
in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn
the subject well enough to get by on the examination, but he is likely soon to forget almost everything he
learned. A little overlearning, on the other hand, is really necessary for one's future development.
