The type of memory

Summary:Memory by short-term memory and long-term memory are two types, each stage, the role of memory types are different, you need scientific arrangements.

There are two types of memory: short-term memory and long-term memory,

short-term memory

    The definition of short-term memory: the memory of 30 seconds or minutes. Capacity is limited, usually seven words, for example, not easy to remember the 8 phone numbers, but divided into three groups, “53, 9046,728” easy to remember than" 539,046,728 ", when you are familiar with these numbers, will form a long-term memory, In general, will quickly forget the meaning of words or numbers; Leave a deep impression with the impact of the scene, memories for a long time to keep. The longest month of the short-term memory. If the memory is constantly stressed, it will slowly turn the long-term memory, so for the new memory, need a repeat process of learning, thus transformed into a long-term memory

long-term memory

    Longer memory. The long-term memory can be divided into the following categories:

1. Episodic memory: personal memories

2. Semantic memory: knowledge

3. Procedural memory: the procedures of the things perceived by the body

4. Trigger memory: the sources of misunderstanding the (subconsciousness effect).

    More detailed description of the type of long-term memory, see Si Kaier memory classification.

    Different ages, different memory types, the effect is not the same. Memory hierarchy: at the lowest level is procedural memory, above the trigger memory, and semantic memory, short-term memory, the top is episodic memory. Class more lower, more primitive life is to maintain the relative importance of the memory; Class more up, the higher the degree of memory content.

    Process from early childhood development to adult, the first development program memory, followed by priming memory, semantic memory, short-term memory, the latest development of episodic memory.

    Almost no memory from birth to three-year-old. The phenomenon of early childhood amnesia, the reason lies in the development of episodic memory is relatively late. In fact, before the age of 10, the rapid development of semantic memory, over this age on episodic memory gradually gained the upper hand.

   Conversely, some people grow older, memory loss, there will be forgetful symptoms, this is because the memory disappeared from the top. First, episodic memory is the ability to gradually decline, for example, often forget where to put things in daily life, more serious even forget the meal, this is a symptom of early dementia.With the development of symptoms, the semantic memory also began to disappear, and even forget their friends and family.But even so, the deepest procedural memory has been better preserved, has also been retained memories of dress, walk, eat with chopsticks.
