MSM stands for Multi-Store Model of memory. This model, developed by Atkinson and Shiffrin (1968), describes how information flows between three permanent memory storage systems.
Understanding the Multi-Store Model (MSM)
The Multi-Store Model is a key concept in understanding how memory works. It proposes that memory is not a single entity, but rather consists of different stores with varying characteristics.
The Three Stores in MSM
Here's a breakdown of the three main components of the Multi-Store Model:
- Sensory Register (SR): This is the first stage, briefly holding sensory information.
- Short-Term Memory (STM): This store has limited capacity and duration. Information here is consciously processed.
- Long-Term Memory (LTM): This is the final stage, with potentially unlimited capacity and duration for storing information.
Flow of Information in MSM
Information flows between these stores in a sequential manner, according to Atkinson and Shiffrin's model:
- Sensory Input: Information from the environment enters the Sensory Register.
- Attention: If attention is paid to the information in the Sensory Register, it moves to Short-Term Memory.
- Rehearsal: Maintaining information in Short-Term Memory through rehearsal can lead to its transfer to Long-Term Memory.
- Retrieval: Information can be retrieved from Long-Term Memory and brought back into Short-Term Memory when needed.
