Coding system refers to the process in which information passes through three memory stages and is processed. Stimulation from the external environment enters the receptor register through the receptor. The storage time is 0.25 seconds to 1 second. Then part of the information is noticed and enters the short-term memory. The information that is not noticed disappears. The information in short-term memory is stored for 1 second to 1 minute, and the information is mainly encoded in the form of voice. [1]
The information in short-term memory is repeated. Further processing enters long-term memory. At this time, the encoding mode of information is mainly semantic, and the information storage time is more than 1 minute. The information in long-term memory can be retrieved and returned to short-term memory.
