  I. What is memory

  1. The basic theory of memory

  What is memory

  "Memory is the mother of wisdom" - this famous saying of the ancient Greek poet Athiros has been passed down to this day. Memory is a physiological and psychological phenomenon that people can actually feel, what exactly is it?

  Memory is the reflection of past experience in the brain, and can be regarded as the retention of experience, sometimes in the retention also undergoes an active creative mental process, including recognition - retention - cognition (recognition) or recall, which are three sequential development and at the same time inseparable links, is "the basic condition of the whole mental activity".

  It is the "basic condition of the whole mental activity". Among them, the recognition and retention belong to the aspect of "remembering", and the recognition or cognition belongs to the aspect of "recalling". The process of memorization is to identify and remember the characteristics and connections of things, which is the formation of corresponding temporary neural connections in the cerebral cortex; retention is the retention of the traces of temporary connections in the brain, which is the process of consolidating the acquired knowledge and experience; recognition or recall is the reactivation of temporary connections under different conditions.

  From the biological point of view, memory is a special function of the entire central nervous system, and its essence is a biochemical process, i.e., the process of brain physiological activity. Therefore, memory can also be regarded as a comprehensive process of psychological and physiological cooperation between the human brain in accepting, storing and extracting information from things.

  Memory ≠ memory

  Although memory and memory are inseparable, they cannot be directly equated.

  Memory is a kind of intellectual activity, which is expressed as a kind of passing or process, and is a dynamic presentation. Memory, on the other hand, is a special ability that people show in their memory activities. That is, people's ability to remember the image of things or the passage of things, which actually includes various comprehensive abilities such as identification, analysis, processing, abstraction, comparison, generalization, storage and reproduction of various information materials.

  Memory is an important part of intelligence, and its role and position in memory activities is irreplaceable. Of course, in other intellectual activities such as observation, imagination, thinking and creation, memory also plays an important role.

  2. Classification of memory

  According to the main human senses activated when memory is divided.

  (1) Visual memory (2) Auditory memory (3) Olfactory memory

  (4) Taste memory (5) Tactile memory (6) Balance memory

  (7) combined audiovisual memory (8) combined audiovisual and tactile memory

  (9) Combined memory of multiple sensory organs

  The time that the memorized material is maintained in the brain is divided into

  (1) Instantaneous memory

  (1) Instantaneous memory, also known as sensory memory, has a retention time of less than one second, and is so instantaneous and forgettable that people often do not feel it. The brain does not process and repeat such information, and the traces formed are superficial and active, disappearing after one second, and cannot be recovered after forgetting.

  (2) Short-term memory

  It is also called operational memory, which is maintained for more than one second but not more than one or two minutes, and is often associated with certain operational actions. Short-term memory is a normal phenomenon, which can reduce the memory burden of the brain.

  (3) Long-term memory

  The retention time is greater than one or two minutes, and it can usually be maintained for a longer period of time, some of which can last a lifetime. The brain has actively and actively processed such information before storage, and most of the traces formed are structural, profound and solid, which can be maintained for a longer period of time, and most of them can be recalled after forgetting.

  The same content is memorized repeatedly, which can prolong the memory time and transform the short-term memory into long-term memory. The results of animal experiments show that memory traces must last at least 90 seconds in the brains of rats before short-term memory is transformed and consolidated into long-term memory. For humans, it takes only four or five seconds.

  Division of memory material by brain hemisphere.

  (1) Left hemisphere memory: responsible for remembering logical information, verbal information

  (2) Right hemisphere memory: for remembering image information and artistic information

  In addition, people also divide memory into emotional (sensory) and non-emotional (sensory) memory in terms of psychological characteristics, and motor (action) and non-motor (action) memory in terms of physiological characteristics, etc. 3.

  3. Characteristics of memory


  As time passes, each person's memory of knowledge, experiences, events, objects, etc. does not remain unchanged. Some of the contents, forms or images are changing implicitly; some of the original experiences are gradually enriched, improved and updated by the continuous enrichment of new experiences.


  Memory is invisible and non-intuitive. As long as people refuse to transcribe, speak, write or otherwise reproduce what they have memorized in their minds, others cannot access it.

  Incomplete reliability

  The fallibility of memory leads to incomplete reliability when recalling. The recalled knowledge, experiences, events, images of objects, etc. are not guaranteed to be the prototypes they were when they were first remembered, and some of them may become more complete over time; they may become fragmented; they may become misshapen or deformed; they may expand or contract in whole or in part.


  According to research, the human brain can remember four different pieces of data in a period of 50 milliseconds to half a second. The normal human brain can remember knowledge, experiences, events, etc. of interest in the blink of an eye.

  What people remember is also instantaneous when they access it. People can also compare the remembered information in a short period of time, such as this and that, past and present, etc.


  The memory potential of every normal person is infinite. Darnell Danin described it graphically: "Our memory is like a doll (a peasant woman's costume doll, usually made of wood, the outermost one is the largest): remove one, there is another inside."

  4. The performance of excellent memory


  It is related to speed, that is, "remember quickly". A quick memory saves time, increases efficiency, and allows you to acquire more knowledge.


  It is related to firmness, that is, "remembering well". Long-lasting and long-lasting memory improves the effectiveness of memory.
