Multi-store Model of Memory (MSM) - Coggle Diagram
Multi-store Model of Memory (MSM)
The multi-store model of memory was proposed by Atkinson and Shiffrin ( 1968) and was one of the first models of memory.
Memory stages
For a memory to go into storage, it has to pass through three distinct stages: the sensory register, short-term memory, and finally long-term memory.
These stages were first proposed by Richard Atkinson and Richard Shiffrin.
Their model of human memory is called Atkinson-Shiffrin (A-S). It is based on the belief that we process memories in the same way that a computer processes information.
Memory variables
There are three variables that can be used to describe the stores that information passes through: coding, capacity and duration.
Coding is the process of changing information from the environment to store it in memory.
Capacity is the amount of information that can be stored.
Duration is the time period that information is held in the memory stores.
Sensory register
The sensory register store is constantly getting information from all of our senses about the world around us. The information is quickly discarded or transferred to short-term memory.
Sensory register storage
In the Atkinson-Shiffrin model, stimuli from the environment are processes first in sensory register - storage of brief sensory events, such as sights, sounds, and tastes.
Duration
It is very brief - up to a couple of seconds.
We are constantly bombarded with sensory information.
We cannot absorb all of it, or even most of it. Most of it has no impact on our lives.
What is stored?
Sensory information can be sights, sounds, and even textures.
If we do not view the information as valuable information, we discard it, and its duration will be very short.
If we view something as valuable, the information will move into our short-term memory system.
Summary
Duration - very quick (0.5 seconds)
Capacity - large
Coding - specific to each sense
