What are the time of instantaneous memory, short-term memory and long-term memory? (Educational Psychology)

(1) The storage time of instantaneous memory is about 0.25 seconds to 2 seconds.

(2) The retention time of short-term memory is about 5 seconds to 2 minutes.

(3) Long-term memory is stored for more than 1 minute, until it is accompanied by people's life.

Instantaneous memory, also known as sensory memory, is caused by stimulation acting on sensory organs. Instantaneous memory time is very short, and many noticed information easily disappears, and those that can be remembered enter short-term memory.

Short-term memory is a stage between sensory memory and long-term memory. Short-term memory is an internal mechanism in which cognitive resources are concentrated on a small number of psychological representations. Information coding is mainly auditory coding, but there are also visual coding and semantic coding.

Long-term memory, the information mainly comes from the content repeated in short-term memory stage, and it is also formed because of deep impression. The capacity of long-term memory is infinite, and information is stored in an organized state.

Extended data

There is a certain relationship among sensory memory, short-term memory and long-term memory.

The information in sensory memory can enter short-term memory if we pay attention; The information in short-term memory can enter long-term memory after retelling and recoding. Short-term memory also contains information from long-term memory, and short-term memory and long-term memory are highly interdependent.

These two kinds of memories can be regarded as different aspects of information: short-term memory involves a small amount of temporary and active information, while long-term memory involves a large amount of relatively permanent coded information.

Information stored in long-term memory can be divided into words and images, and there are two ways to organize information: speech coding and image coding.

Speech coding is to form "chunks" of speech materials by word processing information, meaning, grammatical relationship and system classification to help memory. Image coding uses visual images, sound, taste and tactile images to organize materials and help memory. These two coding methods have their own characteristics.

It is generally believed that the two hemispheres of the brain are divided into two parts, the left brain tube language and the right brain tube representation. Generally speaking, in long-term memory, the coding of information is often combined with two ways, which complement each other, but there are also individual differences. Some people like to code in this way, while others like to code in another way.
