Multi-store Memory Model (MSM) | International Baccalaureate

Multi-Store Memory Model

Theory proposed by Atkinson and Shiffrin 1968.

The model suggests that our memory consists of separate components in which information is processed.

• Sequential and works in a single uniform way.

• Sensory Information —> Sensory Memory

• Sensory Memory —> Short-Term Memory

• Short-Term Memory —> Long-Term Memory

Sensory Memory

Memory originated from information processed by the 5 senses:

• Hearing

• Smelling

• Touch

• Sight

• Taste

Short-Term Memory (STM)

Transferred from sensory memory with the help of selective attention.

Capacity = 7+2 Items

Duration = 6-18 Seconds

Long-Term Memory (LTM)

Transferred from short-term memory with help of rehearsal.

Capacity = Unlimited

Duration = Lifelong
