Multi-store memory model

Who proposed this?

Atkinson and shiffrin

What is MSM suggesting?

That the memory consists of three separate stores; sensory register, STM, LTM.

Information flows in a linear sequence from one store to the next

What are the key process of MSM?

Attention: This is needed to pass from sensory register to STM, without this STM decays

Rehearsal: Maintenance rehearsal keeps information in STM

Retrieval: Information from LTM is brought back into STM when it is needed for use

Features of sensory register

1. You get stimulus from environment

2. Each store is modality specific

3. Capacity is large

4. Duration is 250 milliseconds

STM features

1. Coded acoustically (dissimilar)

2. Capacity is 5-9

3. Duration is 18-30 seconds

What is displacement in STM?

When information exceeds 5-9 items, it will push some out for the new information.

What is elaborative rehearsal?

When you link the memory to existing knowledge therefore making it meaningful. This makes it easier for STM to become LTM

LTM features

1. Coded semantically dissimilar

2. Capacity is unlimited

3. Duration is lifetime

What is retrieval failure?

Occurs it LTM when the memory exists but you fail to retrieve it because of the lack of cues

What did Glanzer and Cunitz come up with?

Recency: refers to the tendency to remember items at the end of a list better than those in the middle

Primacy: refers to the tendency of remembering items at the beginning of a list better than those in the middle
