シナジーのメタファー１

A) Memory

　As Hanamura (2005) explained, memory serves as the basis of ironic relations because inference is based on it. It is consciously simplified to avoid making the understanding of the fuzzy logic difficult.
　Memory is characterized by the ability to save information and recall it as needed. For this, there are two different methods: short-term memory and long-term memory. The former saves information for a few seconds to minutes, and the later retains it for a lifetime.
　There are two classifications for short term memory, sensory memory and primary memory.
Sensory stimuli are automatically saved in the sensory memory for a period of few hundred milliseconds to be coded for short-term storage, and to move into the most important features. The memory begins to fade immediately after the acceptance. The transmission of information from the short-term sensory memory to a stable memory can happen in two ways; the first is the verbal coding of the sensory data, the second is a non-verbal way that is little-known.
　Primary memory performs the temporary acceptance of verbally coded materials. Its capacity is smaller than sensory memory. Non-verbal coded material is simplified from the primary memory to the stable secondary memory during “exercises”, for example, repetition.
　There are also two classifications for long term memory, that is, secondary memory and tertiary memory.
　Secondary memory is a large and stable storage system. The difference from the primary memory can be identified clearly depending on the type of mistake the memory makes when recalling. Primary memory makes mistakes of phonetic-similar sounds such as “p/ b”, and the secondary memory confuses words that are of similar meaning.
　Another memory distinction is the time it takes to access. Primary memory recalls it quickly, and secondary memory more slowly. The loss of secondary memory retention seems to depend on the interference of the learning process during the learned knowledge. First a proactive inhibition and then a retroactive inhibition. Proactive inhibition is the more important factor because we have to control a large stock of learned knowledge. Therefore, this is the largest culprit of memory extinction.
　The tertiary memory deals with engram, for example, one’s own name, skill to read and write or other practiced forms that are permanently retained from many years of practice, even if all other memory contents are lost somehow. The engram is also distinguished as having an extremely quick access time, as it is saved in a special memory form, the tertiary memory.
　But a very good consolidated engram can also work with the secondary memory. The model of long-term memory corresponds to the secondary memory plus the tertiary memory.
