It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions (感知物) , the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.
Memory can be defined as the capacity to keep information available (有效的) for later use. It includes not only “remembering” things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sensed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.
Memory exists not only in humans and animals but also in some physical objects and machines.
Computers, for example, contain devices for storing data (数据) for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instantaccess memory of a large computer may hold up to 100000 “words” ready for instant use. An average U.S. ? teenager probably recognizes the meaning of about 100000 words of English. However, this is but a fraction (片段) of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight. |
